Auto-brightness is a great feature that can help automatically manage your iPhone’s brightness depending on a different environment and lighting conditions. But, sometimes, when you’re outside in the sun and open your iPhone, you realize the screen keeps dimming repeatedly even when auto-brightness is turned off.

Occasionally, the sensor malfunctions to accurately detect the environment, creating the screen dimming issue. It can happen because of a software bug, or you have enabled the features that control the brightness. However, you can disable this feature and control brightness manually. 

This article will cover the possible causes and fixes you can use to solve your issues with auto-brightness.

Why is iPhone Screen Dimming With Auto-brightness Off

There are several causes for iPhone screens to keep dimming with auto-brightness off. Here are the possible causes that might lead to this issue. 

Device Overheating: Your iPhone screen will automatically dim even though you have disabled the auto-brightness. It will dim once your device temperature reaches more than 40°C. This is done to protect your iPhone from physical damage.

True Tone: If you have turned off the auto-brightness, but your True Tone feature is on your iPhone. Then, it can adjust the brightness according to the environment, just like auto-brightness.

Night Shift: Another possible cause for your iPhone to keep dimming would be if you have turned on the Night Shift. This feature will reduce blue light per your scheduled time and shift to night brightness.

Low Power Mode: Your iPhone screen brightness will drop if you switch to Low Power Mode to save your battery. 

Low Battery: If your iPhone is running out of your battery, it’s normal to drop brightness levels. This is done to save your battery to use for a longer time.

How to Fix iPhone Screen From Keep Dimming

You don’t need to worry if your iPhone screen keeps dimming. It can happen if you have turned on Low Power Mode or other features. You can easily fix this by simply rebooting or updating your iPhone. Here I have compiled some quick fixes you can use to stop your iPhone from dimming.

Turn Off Auto-Brightness

The first thing you need to ensure is whether your Auto-brightness setting is turned on or not. Auto-Brightness helps adjust the brightness levels depending on your surroundings. 

Here’re the steps to turn on auto-brightness settings on your iPhone:

Turn Off Night Shift

If you have enabled the Night Shift, this will automatically switch your display to warmer color as per your scheduled time, reducing your iPhone’s brightness. You may have unintentionally set the feature to be enabled at the wrong time or during the daytime making your iPhone brightness dimmer. 

Turn Off True Tone

True Tone can also act as an auto-brightness feature that uses sensors to adapt the color and brightness of your display based on the lighting conditions around you.

It’s a hit-and-miss feature that doesn’t always work effectively, causing fluctuations in the brightness of your iPhone’s display. Turning off True Tone will stop your display from fluctuating and will resolve the dimming problem. 

Or, you can try these steps to turn it off from the control center.

Disable Low Power Mode

It can be a great feature if you run out of juice on your iPhone as it preserves the battery by disabling some other features and reducing the background activities. However, screen brightness consumes most of the battery. The first thing low power mode will do is reduce your iPhone’s brightness so that it can last longer.

If you have turned on Low Power Mode, consider disabling this feature. Once you turn this off, your display will be back to normal. 

Disable Zoom Filter

If you have accidentally enabled this feature. Then, disabling the zoom filter can also work if your screen keeps dimming even without auto-brightness. To turn this feature off,

Turn Off Auto-Lock

This Auto-Lock will dim the screen before your iPhone is about to get locked. This feature is useful, too, as it will lock your device if you leave it idle for more than 30 seconds or as per your setup time. You can turn this off by following the given instructions.

Note: When in Low Power Mode, your iPhone is auto-lock which is restricted to 30 seconds.

Restart Your iPhone

Restarting is the one that can solve almost all common bugs. It forces your iPhone to end all the previous tasks and begin with new ones. Restarting can also fix this problem of dimming.

You can power off your iPhone device using the steps below:

Press and hold down the power button.

Swipe to the right to power off. 

Now, Press and hold down the power button for 3-4 seconds.

Apple logo will appear, which means it is turning on.

Here’re the steps to force restart your iPhone:

First, Tap once on Volume up and Volume Down, then hold the power button until the screen goes black.

Once the screen goes black, leave it for 5 seconds.

Then, press the power button until you see the Apple logo.

Cool Down Your Device

If you are using your iPhone excessively without giving it a break, your phone will heat up. Also, if you are using it while charging and tons of apps are loaded in the background, it will increase your device temperature, forcing it to drop its brightness. 

You can cool down your iPhone quicker by closing all the background apps, taking off the phone’s case, and turning on Airplane mode. Switching it off can also work to cool down your chúng tôi will also get a warning when your iPhone gets excessive heat.

At such times you won’t be able to use your iPhone. Once it returns to normal temperature, your brightness level will also turn bright.

Update Your iPhone

If your screen keeps dimming, although your auto-brightness is off, it can be fixed by software update if it’s a problem caused by iOS bugs. When updating your iPhone, Apple adds new features and fixes previous software bugs. So, consider updating your iPhone if you haven’t. 

Resetting Your iPhone

Although you have tried previous methods, this can be another option you can consider if your device’s brightness keeps going down. Resetting can help reinitialize the system’s settings and delete all the previous data.

The resetting process on iPhone involves two major steps, first, you need to backup your device to iCloud and then erase all the contents on the iPhone.

Here’re the steps to backup your device to iCloud:

Note: Make sure to

Make sure to back up your files to iCloud or third-party storage before resetting your iPhone.

Follow the steps below to reset your iPhone:

No Service On Iphone? Try These 10 Fixes!

Are you unable to make or receive calls? Is your iPhone showing ‘No Service’ or ‘Searching’? Your iPhone may have some software or hardware problems due to which it can’t connect with your carrier. Here are some quick fixes to help you out when your iPhone has no service.

Why your iPhone says ‘No Service’?

It could be a case of carrier settings update gone wrong, or there could be some hardware issue with your iPhone. Also, the chances are that your carrier might be facing some operational issues due to which you are not getting network on your iPhone.

There are quite a few fixes to get rid of the ‘No Service’ error message on your iPhone. Let’s go through each of them.

10 Ways to fix your iPhone when it has no service

1. Check your coverage area

If you live in the rural area, you probably won’t have one of the best cellular receptions. In that case, talk with your service provider and convince them to install cellular towers in your area or get a signal booster for your home.

Alternatively, you can also try enabling Wi-Fi calling if you have a reliable Wi-Fi connection at your home.

2. Turn on/off Airplane mode

First, ensure you don’t have Airplane mode turned on. Now, turn Airplane mode on and then back off.

To do so, go to Settings → toggle on Airplane mode → toggle it off after a few seconds.

This should fix the No Service error, but if you’re still getting the error message, you can check out the fixes mentioned below.

3. Restart your iPhone

Restarting your iPhone might help you get rid of the error. So, don’t hesitate to give it a chance.

On iPhone 8 and earlier: Press and hold the side button and drag the power off slider to turn off the device. After some time, press and hold the side button to turn it on.

4. Reinsert SIM card

Sometimes the problem isn’t too big. This could be the case with your iPhone. Maybe you have not inserted the SIM card correctly, and that’s why your iPhone can’t connect to the carrier. Try reinserting the SIM card properly and restart your iPhone once.

If the problem persists, move on to the next step.

5. Enable Data Roaming

Sometimes your carrier doesn’t connect you to the network if you’re out of your home network zone, leading to the no server error. So, you need to ensure data roaming is enabled on your device.

To do so, open Settings → Cellular → Cellular Data Options → toggle on Data Roaming.

6. Reset Network Settings

On a rare occasion, your network setting may be corrupted, due to which you are getting the No Service error message. So, resetting the network to factory default could help you fix that issue.

To do so, open Settings → General → Reset → Reset Network Settings. Now, enter your passcode and tap Reset Network Settings.

Note: Resetting network settings to default will reset Wi-Fi networks and passwords, cellular settings, VPN, and APN settings.

Sometimes the wrong date and time could be the reason behind the iPhone says no service. To modify date and time, open Settings  → General → Date and Time → turn on Set Automatically → select the appropriate Time Zone.

You could have installed the wrong carrier settings, or there may be some bug in the carrier settings update, resulting in the No Service error message on iPhone. In such a case, see if an update is available for career settings.

Note: Make sure you’re connected to a Wi-Fi network.

Open Settings.

Next, tap Update.

Now reboot your iPhone and check if you’re still getting the No Service error message.

There are chances that the last software update caused this issue. So, it’s better to check for the new iOS update as Apple usually releases new updates that fix the bugs. To do so,

Open Settings.

Now tap General → Software Update.

If none of the fixes worked out for you, there might be some issue from the end of your mobile carrier. It’s best to contact your service provider to help fix the issue.

I hope that the fixes mentioned above solved your issue. If you’re still getting the No Service error, I suggest contacting Apple Support once. It could be a hardware issue.

Is Your Tv Screen Blurry Or Fuzzy? Try These 10 Fixes

This is the age of tack-sharp Ultra High Definition televisions, so why is your TV’s picture so blurry or fuzzy?

You might need a new prescription for your glasses. But if there’s nothing wrong with your eyes, you’ll have to troubleshoot to get the best picture.

Table of Contents

1. Remove Sources of Interference

Some LCD blur or ghosting issues result from electrical interference or faulty surge protectors. To eliminate this as a cause, try plugging your TV directly into the outlet without any power strips or surge suppressors in the chain. If that solves the problem, you can try using a different power strip.

You should also try switching off devices on the same circuit as the TV. Any device with an AC motor, such as a fridge, air conditioner, or fan can cause electrical interference. It’s unlikely that these devices would be on the same circuit as the outlet for your TV, but it’s worth checking.

If you have fluctuating power coming directly from your mains, a UPS that filters out these spikes may be the solution, but you’ll need an electrician to check your supply.

2. Is Your Source Low Resolution?

One of the most common causes of a blurry picture on a flat-screen LCD TV (or monitor) is a mismatch between the content’s resolution and the native resolution capability of the screen.

LCD, Mini-LED, microLED, Plasma, OLED, or QD-OLED all use different types of technology to make moving pictures. However, one thing they all have in common is a “native” resolution. This refers to the TV’s grid of physical pixels (picture elements). A 4K UHD TV has a pixel grid of 3840 x 2160 pixels. This is four times as many pixels as a Full HD TV at 1920×1080. So, for every pixel of information in a Full HD image source, the TV must fill four physical pixels’ worth of data.

There are various methods of “upscaling” lower-resolution images to high-resolution displays, and they all have varying levels of success. Going from FHD to UHD is straightforward since it involves making groups of four pixels act as a single pixel. Whenever the resolution of the source image divides evenly into the target screen’s resolution, you’ll get a softer image, but it will still look good.

If the source doesn’t divide perfectly into the target, you may get an ugly smeary result. Many of the fixes listed below can help to fix blurry or fuzzy upscaling results.

3. Change Your Upscaling Settings (Or Your Upscaler)

Various TVs and set-top box devices offer different options regarding how they should scale lower-resolution sources to a higher-resolution screen. We can’t be very specific here because different devices and TVs have other names and menu systems. So you’re better off looking in your manual or online for anything to do with “upscaling” and your devices.

One important tip we can give you is to avoid having the TV itself do the upscaling. High-end televisions may have superior upscaling technology, but mid-range and low-end sets generally don’t have the processing power to upscale with good results.

Instead, if you’re using a connected device like a cable box, gaming console, Android TV, Apple TV, or another similar source, set its output resolution to match your TV’s native resolution. Any upscaling will happen on that device before it reaches the TV.

4. Change Your Streaming Picture Quality Settings

If you are watching a streaming video source (such as the Netflix or Hulu app on a smart TV), then the fuzzy image may have nothing to do with your TV and everything to do with your bandwidth or quality settings.

Go to the picture settings of your streaming app of choice and set your quality and bandwidth usage preference. With some streaming apps (e.g., Disney Plus), you can select the preferred quality while watching your content. Change the quality setting from automatic to a setting that matches what your TV was designed to display.

Bear in mind that your internet connection may simply be too slow to stream at your TV’s sharpest quality. It may also take a few seconds for the stream to switch to the higher-quality mode. There are also different quality “bitrates” within each resolution tier. So although you may be streaming at (for example) 4K, if it’s at the lower end of the bitrate for that resolution, there can still be blurring, fuzziness, or other artifacts in the picture.

5. Is the Source Digital or Analog?

HDMI is a digital image standard, ensuring you get the source’s quality without degradation. If you’re using an analog source, such as a DVD player connected using RCA connectors, there can be a significant amount of interference or signal loss based on several factors.

If at all possible, switch to HDMI instead. Returning to our DVD player example, some models provide HDMI output and have internal upscalers designed to make DVD footage look sharper on modern HDTVs.

6. Try a Different HDMI Cable or Port

HDMI is digital, and usually, it works correctly or not at all. We have seen situations, though, where bad ports or cables can cause snow or other image artifacts. HDMI is built to have a certain level of digital error correction. However, if the amount of electrical interference or damage to a cable or port passes a threshold, it may degrade the image.

One fix for a blurry or fuzzy video is to switch out the HDMI cable or move it to another input on the TV to check if there might be something wrong with the cable or the port.

7. Change The Sharpness Settings

Virtually all modern HDTVs offer a form of digital sharpening. This is usually listed under TV settings alongside contrast, brightness, etc. Use your TV remote control to access those menus, usually by first pressing the menu button. 

Lowering the sharpness level will soften the image. It might be that your sharpness setting has softened things so much that the display looks blurry or fuzzy. The answer, of course, is to turn the sharpness up until you’re happy with the result.

Increasing the sharpness filter is also an effective way to deal with blurriness in the source footage. Still, there’s only so much that can be done before the image looks over-sharpened and unappealing.

8. Turn On Blur-Reduction Features

Unlike CRT (cathode ray tube) TVs, all modern flat-screen TVs exhibit a type of motion blur known as sample-and-hold motion blur. In addition, lower-end TVs may have inherent blur as the individual pixels change their state too slowly.

Companies like Samsung and Sony have worked tirelessly to create new panel technologies to combat these issues. If you have an old TV, it may not benefit from the fast pixel response times more recent models can achieve.

As for motion blur caused by the sample-and-hold nature of flat panel technology, there are two main features you can activate to combat it. The first is motion smoothing, also known as frame interpolation. Different TV brands have other names, so you’ll have to look for something that refers to motion, smoothness, or do a web search for your TV model with the term “motion smoothing.”

This feature creates new frames from the existing frames in the video to offer liquid-smooth blur-free motion. This is the much-derided “soap opera effect,” but you may prefer the crispness of this mode for some content, such as HD sports broadcasts.

The second feature is something known as Black Frame Insertion (BFI). This inserts a black frame between every frame displayed on the screen. This makes the TV offer motion closer to a pulsed CRT display, thus defeating sample-and-hold blur. However, this comes at the cost of brightness and vibrancy. Newer TVs don’t suffer as much as older models, but either way, you can switch the feature on and decide which image you prefer.

9. Turn Off Image Post-processing

Post-processing features are all of the things that the TV does to the image before displaying it. TV manufacturers have a “secret sauce” of algorithms that help make images look better, but too much post-processing can leave a soft and blurry image.

Turn off as many post-processing effects as possible, using your TV manual as a guide, and then experiment with the ones that offer the best picture without causing too much blur. Noise reduction may be one of the most important settings to adjust if you’re experiencing a snowy or speckled image.

10. Get a Professional Assessment

If nothing you’ve tried above seems to resolve your fuzzy, blurry TV, it’s probably time to have a professional tech support person look at your TV. In some cases, it may be as simple as replacing a relatively inexpensive component. But if there’s something wrong with the core components of the TV, it’s often not worth the expense to replace those major parts. If your TV is still under warranty, you should refrain from letting anyone work on it, even if it is a minor problem. Instead, have it repaired and replaced under warranty.

Iphone Turning Itself Off And Won’t Turn Back On? Try These 8 Fixes

Does your iPhone switch off randomly even if it has sufficient battery left, and then refuse to turn back on? Follow along as we share why this happens and how to fix an iPhone that keeps shutting down on its own.

Why does your iPhone shut down randomly?

Your iPhone will shut down randomly due to high temperature, software bugs, app crashes, water damage, or glitches picked up during regular use. Secondly, your old iPhone can also keep turning off due to poor battery health. You can check the battery health of your iPhone and understand more here.


During an episode of our podcast, I mentioned that I had overslept that morning due to my iPhone 11 Pro turning itself off overnight. It was positioned perfectly on a wireless charger, with plenty of battery left from the day before, and it had no water damage or any other notable hardware concerns. It simply turned itself off and wouldn’t turn back on.

As it turns out, this is just one of those things that sometimes happens to iPhone models X and newer. Luckily, after some stringent Googling, I could work out an easy fix for it. So I thought it would be helpful if I shared that fix (and some more) in case you’re ever unlucky enough to come across this weird bug.

How to fix an iPhone that won’t turn back on

Force restart your iPhone

Once you’ve confirmed your iPhone has at least some battery, and it won’t turn on with a simple press of the power button, go ahead and perform a force restart. We have a dedicated tutorial for all devices. If you have iPhone 8, X, or later, we have recapped the steps below:

Press the volume up button and release it quickly. This is more of a tap than a press-and-hold.

Do the same thing with the volume down button. Again, it’s just a quick press.

Press and hold the Power/Sleep button, and this time keep holding until you see the Apple logo appear on the screen.

The steps should be done rather quickly: press volume up, press volume down, and then press & hold the Power button. If you hold on to one of the volume buttons too long or don’t hold the power button long enough, it may not work.

Plug your iPhone into charging

If a force restart isn’t able to switch on your iPhone, plug it into charging for at least 15 to 30 minutes. Once the battery is adequately juiced up, try to switch on your iPhone normally or force restart it again.

Let the iPhone cool down

iPhone can heat up significantly if left on a wireless charger or a sunny day with maximum brightness, GPS, and many running apps. Once the internal temperature gets high enough, your iPhone becomes almost unusable or shuts down. You can turn it back on after it has cooled down.

Reset all iPhone settings

If your iPhone keeps turning off, reset all settings, and this should hopefully fix the problem.

Check for water damage

Your iPhone has a Liquid Contact Indicator (LCI) that is normally white or silver. But when it comes in contact with water, it turns red. Here’s how to determine if your iPhone is water damaged or not:

Set your device in bright light, and also make sure you have a flashlight handy.

Take out the SIM card tray and look inside.

If the LCI is red, water has gone inside your device, due to which it is performing inconsistently and turning off randomly or refusing to power on. Take it to an Apple Store to fix the problem.

Try DFU mode or full erase and set up

Once you have followed everything and the problem continues, put your iPhone in DFU mode (Device Firmware Update) and erase it. This will remove everything from your device and fix the software issues causing your iPhone to turn off and refuse to turn on. Before proceeding, make sure your back up your iPhone to iCloud or computer.

Note: If you can’t use DFU mode due to lack of technical skills or fast internet, take it to an Apple Store, and they should assist.

Finally, if nothing helps, book an appointment at your nearest Apple Store or Apple-authorized store and get your device inspected. They will inspect the iPhone and tell you the exact hardware problem related to the internals or the battery.

Samsung Dex Not Working? Try These Fixes

Samsung DeX is an amazing feature that offers a desktop-like experience via a bigger display on a Samsung Galaxy phone. If you use it regularly, but it suddenly stops working, you may be wondering what happened. Thankfully, you can easily make it work again by following the fixes provided below. Let’s check different ways to bring the Samsung DeX functionality back on track.

1. Restart All Connected Devices

The first thing you must do if Samsung DeX isn’t working is restart all of the connected devices, including:

Samsung Galaxy phone

Wi-Fi modem, if you are connecting wirelessly

PC, if you are using DeX on a PC

TV, if you are connecting DeX on a TV

2. Check Compatibility

For DeX to work properly, you must check whether the devices are compatible. Samsung DeX doesn’t work on all Samsung phones. It’s available only on the Samsung S8 series and up, except for the Galaxy Flip series.

Furthermore, you must have a TV that supports Miracast technology to use DeX wirelessly. Similarly, Windows PCs with an ARM processor may not be compatible with DeX. Touchscreen displays and Samsung DeX for Mac are also not supported. Check the list of the DeX-compatible devices and displays on Samsung’s official webpage.

Tip: check out other ways to run Android apps on PC.

3. Check Connected Hardware

Hardware plays a significant role in DeX working properly. You must ensure that everything is working smoothly. For instance, if you are using a DeX station, make sure your phone is seated properly. If necessary, remove the phone and replace it.

If DeX isn’t working on your TV or monitor, try connecting it to a different device. There are chances that the monitor may not be compatible with DeX.

4. Check USB Cable

For DeX connections via cable, ensure that the cable is securely plugged in. Remove and reconnect it. Also, try using the original cable that came with your phone and connect via a different port on your PC or monitor to get DeX working again.

5. Connect to the Same Wi-Fi Network

If you are trying to use DeX wirelessly, ensure that your phone and the device that you are trying to connect (TV or PC) are on the same Wi-Fi network.

Tip: is your Wi-Fi connection slow around the house? These steps can help remedy the situation.

6. Switch to a Different Wi-Fi Band

Some displays are not compatible with the 5GHz Wi-Fi band, so it would help if you switched to the 2.5 GHz network on both devices in Wi-Fi settings.

7. Disable the Power-Saving Mode

When using DeX mode, you must turn off the power-saving mode on your phone.

Turn off the toggle next to “Power saving.”

Also, try to charge your phone before using DeX or keep it plugged in when connecting DeX.

If you are using a USB to HDMI hub, make sure to connect it to a power supply; otherwise, you will only be able to screen mirror and will not have full use of the capabilities of DeX.

8. Turn Off VPN

DeX may not work properly if your phone or TV/PC is connected to a VPN. You must turn off your VPN, then try using DeX.

9. Change USB Mode on the Phone

Whenever you connect your phone to your PC using a USB cable, you will see a USB options notification in the notification panel. Tap on this notification, then try resetting the connection by switching to “Charging phone only,” then back to “Transfer files.” This should fix the issue of DeX not working.

10. Install, Open, or Restart the DeX App on PC

Unlike a TV, where you can use DeX without installing anything, you need to first download the DeX software to your Windows PC.

Next, make sure that the DeX app is open on your Windows PC when you are trying to use it. There’s a chance that your PC has closed the DeX app. If you don’t see the DeX app icon on the taskbar, open it.

However, if the DeX app is already running, restart the app by closing it and reopening it.

Press the “Start DeX” button. Also, enable the toggle next to “Auto start when HDMI is connected.” This will automatically start DeX mode when you connect an HDMI cable.

13. Select Right Connection Mode

On OneUI 5 and above, both your PC and TV/monitor will show up in the list of available devices under the “Connect wirelessly” section.

On the earlier versions of OneUI, Samsung offers two separate modes for connecting DeX: “DeX on TV” (or monitor) and “DeX on PC.” You must select the proper mode when connecting DeX.

14. Select Samsung DeX from Notification Panel

After connecting DeX, if your TV or monitor starts mirroring your phone instead of switching to DeX, you must tap on the Samsung DeX notification in the notification panel followed by Samsung DeX. That’s it. Samsung DeX mode will instantly launch on the connected device.

Pro Tip: on some phones, you may need to search for HDMI mode settings and switch to DeX from mirroring.

If you are able to connect your phone to your PC wirelessly, but the USB mode doesn’t work, you must update the USB drivers on your Windows PC. The issue with Samsung DeX not working could be happening due to outdated drivers.

Connect your phone and PC via the USB cable.

16. Clear Cache and Data of DeX App on Your Phone

As with everything, you must try the golden trick of clearing the cache and data of all the DeX-related apps on your Samsung Galaxy phone to fix DeX not working.

Open Settings on your Samsung Galaxy phone.

Go to “Apps.”

Tap on the Sort and Filter icon and enable the toggle next to “Show system apps.” Press the “OK” button.

Type “DeX” in the search at the top, then select each item that shows, one by one.

Restart your phone.

Good to know: have a Samsung TV? Learn how to pair it with Alexa.

If Samsung DeX fails to work on your PC, you must update the DeX PC app. You may be using an old version of the app, and it may have a bug or not be compatible with your phone. To update the Samsung DeX app on your Windows PC, follow these steps:

Launch the DeX app on your computer.

18. Reinstall DeX App on Your PC

If updating the DeX app didn’t help it work on your PC, then you must reinstall the app. Uninstall the DeX app from your computer, restart your computer, then install the app again.

19. Start Samsung Services on Your PC

If you are connecting DeX to your PC using a cable, ensure that Samsung Mobile connectivity services have been started. Typically, the services are set to start automatically, but this may have changed.

In your Windows search, type “Services” and select the best match underneath.

Reconnect the USB cable.

20. Add Wireless Display Feature on Windows 11

If Samsung DeX isn’t working on Windows 11, you may need to manually add the Miracast (wireless display) feature on some PCs running Windows 11.

Search for a “Wireless Display.” Select it and hit the “Next” button. Follow the on-screen instructions to install it.

After installing it, restart your computer, then try using DeX on PC.

21. Download Samsung DeX Patch

If your Samsung Galaxy phone is issued and administrated by a business, and DeX mode doesn’t start, you will need to download the DeX patch. But first, check whether a patch is required.

Disconnect your phone from the monitor.

Scroll down and look for “Knox Customization.” If it appears, you will need to download the DeX patch. Open the Knox website in a browser on your Samsung phone and follow the on-screen instructions to download the patch.

Do you have a company- or school-owned PC? If yes, and the above solutions didn’t help, you must contact the admin of your PC, as some public computers have security software installed that prevents DeX from running properly.

23. Reset Settings on Your Samsung Phone

Lastly, if Dex isn’t working, you must reset the settings on your Samsung phone. Doing so will restore all the settings to their original values, fixing the issues you may be facing while using DeX. Don’t worry, as this will not delete any data or files from your phone.

Tip: customization is one of the strong points of Samsung Galaxy phones. We show you how to personalize your home screen according to your preferences.

Frequently Asked Questions How can I fix DeX not working on my Mac?

As mentioned earlier, Samsung DeX is no longer supported on Mac. But if you have the older version installed, and it’s not working, you need to allow certain permissions.

How can I reset Samsung DeX?

There is no option to reset Samsung DeX. On a PC, reinstall the app, and on a phone, clear the data of the DeX apps.

Switch Dock Not Working? Try These Fixes

When the Dock does not work, both the display and USB port fails to respond, and the green LED on the corner does not light up. Although it may seem like the faulty power cable is to blame, we cannot rule out other possible causes like HDMI issues, the device being low on power or the device being in an error state.

There could be a slew of fixes. Checking the green LED is the easiest method. This indicates whether or not the device is receiving power. If the device receives power, the problem is most likely with its firmware or ports. And you might want to start by repairing those components. However, depending on what caused the issue, there may be more than one solution.

When a Nintendo Switch Dock stops working, there are two things that could have happened. Whether the device is not getting power or there could be other technical issues.

The device usually faces power issues due to a faulty power adapter or the port itself. On the other hand, technical issues could be anything from a defective display cable to a damaged dock.

Faulty HDMI cable

Nintendo Switch Outdated

Damaged Power Cable

Wrong display source on your screen

Damaged Switch Dock

Now that you know why Switch Dock stops working, let us understand how you can fix it.

First, restart both the Dock and the Switch and connect the two. Now check the Switch dock for a green LED. 

If the LED is on, the issue is likely with the ports or configurations. If the LED does not turn on, remove and reconnect all the cables that go into your Dock. 

If that does not work, you might want to power cycle the Switch.

Any parts inside a hardware component need to interact with each other to function. If a system or a device enters a deadlock situation where components cannot interact with each other, the entire device may not work.

This is where power cycling a device comes in. Power cycling a device frees it from all remaining charges which removes any configuration stored. This in turn returns the device to its base state or a stable state, fixing any errors or bugs causing the malfunction.

To power cycle the Switch,

Remove the Switch from the Dock.

Now plug everything back, connect the Switch to the Dock, and turn it on.

If power cycling does not work, you may need to insert the cables in the correct order before turning on the Switch.

Sometimes, the Switch dock only works when you insert cables in the correct order. Users in many Q&A forums have reported that connecting the power to the Dock solved the issue. Power issues may stop the ports from being detected when you connect them before the power supply. 

It could also simply be a bug in Nintendo Switch. Nevertheless, here is how you need to connect the cables in Nintendo Switch.

Now connect one end of the HDMI cable to the Dock.

Connect another end of HDMI to the display device.

A bug in the device could be the reason Nintendo Switch is having issues connecting to the Dock. In that case, we recommend that you update your Switch right away. Updating Switch not only fixes any bugs and errors with the device but also brings new features and security upgrades.

To update Switch,

Turn on the Switch.

Scroll down to System.

Select Update and then press OK.

Once the process is complete, Switch will automatically restart.

Now connect Switch to the Dock and the Dock to your display device to see if the update fixed the problem.

When Switch is connected to a display device, Match TV Power State allows both your display device and Switch to turn on and off together. Meaning that when you turn on the display device, Switch automatically turns on and turns off when you turn off your primary display screen. 

Enabling this feature can confuse Switch when turning off the display device and trying to turn on Switch. If that’s the case for you, we recommend that you disable Match TV Power State from TV Output settings.

Turn on the Switch.

Select the gear icon to open System Settings.

Scroll down to TV Settings.

If the green light on the Dock turns on, but you still do not get any display, the problem could be with the HDMI cable. HDMI cables do transfer video data efficiently. However, they are known to be faulty as well. Besides this, these cables do not age well with time, as frequent twists and turns are known to damage them.

Furthermore, you may also have issues getting any display on your monitor if the HDMI port version on the Dock does not match the HDMI cable’s version. Therefore, make sure that you are using the correct HDMI type.

Try using a different HDMI cable, one that matches the HDMI version and is not faulty, to connect the Dock to the display source to see if it fixes the issue.

Another reason the Switch dock does not seem to be working is if the display device is taking a different source as input. You will find several input ports on your display device. Therefore, you can select the input source from which the monitor takes input.

You need to make sure that the currently selected source on your display device is the one to which Switch is connected.

If you are on a TV, navigate through display settings and set the correct Source. On a monitor, however, you will need to navigate settings using the side buttons. 

Note: Depending on the monitor or TV, you will need to navigate through the display configuration to find the correct settings. 

Dust and debris on your display ports could be obstructing data transfer between the Switch and the display device. If this happens, the output screen will not display anything, making it seem like the Switch Dock is faulty.

Try cleaning both the ports on the Dock and the display device using a can of compressed air. Make sure that both the ports and the cables are clean before inserting them.

When you connect the Dock to a screen, the green light on the Dock will turn on. If this light fails to turn on, there is a high chance that it is not getting power or the battery draining fast and taking long time to charge. In that case, try using a different cable to power Switch Dock.

If the second power cable still does not work, it could be that the Dock itself is at fault.

If none of the solutions works, you can try using a separate dock to determine where the problem lies. If you still do not get anything on the screen after connecting the Switch to a different Dock, there is a high chance that the connector that joins the Switch to the Dock is faulty.

However, if the new Dock works, the issue is likely with the older Nintendo Switch dock, and you need to replace or repair it. You can try taking the Switch dock to a local electronic repair shop to get an idea about what caused the malfunction and ways you can fix it.
