Here Are 6 Ways To Fix It

Back when Apple decided to do away with the headphone jack, the company cited that the technology was just too old to be effectively useful. All major Android powerhouses laughed at Apple’s decision at the time, but now, almost all of them have chucked the headphone jacks, especially from upper mid-range or flagship devices. However, there’s no shortage of love for the 3.5mm slot, especially in customers who are more comfortable with budget or midrange devices.

Usually, headphone jacks are as reliable as they come. However, like all the other pieces of tech, the 3.5mm jack, too, is susceptible to the occasional glitches. Today, we’ll discuss the rare flaws of the headphone jack and help you get it up and running as soon as possible.

How to fix the headphone jack on your phone

Being a port that is designed to handle multiple entries for thousands of usages, you don’t expect the headphone jack on your phone to falter easily. However, there can be circumstances under which you can’t seem to hear audio coming from the earphones connected to the headphone jack or there’s some static disrupting your sound experience.

In either of these cases, there can more than just a singular reason as to why the headphone jack is not working. We’ve sieved through the user compliant forums to find what issues users face and how can these problems with the headphone jack be easily resolved using the tips given below.

Solution No.1: Check the headphones

It may seem like a no-brainer to most, but the fact that so many people overlook this basic fix for the headphone jack problem requires it to be explicitly mentioned. There is a chance that there could be nothing wrong with the headphone jack of your smartphone, but the real problem could lie with the 3.5mm port that goes into it – aka the headphones.

The easiest way to find out if the headphones are the real culprit is by plugging them into a different smartphone or media device and listening to whether the audio. If you still can’t seem to hear any sound being produced, then the issue could lie with the headphones, but if the headphones seem to work fine, then move on to the real ways of fixing the headphone jack.

Solution 2: Check the device’s settings

If your headphone is working fine on other devices, then it’s time to check out the device’s settings and see if everything is in order. Since there aren’t many settings to check, this process should be fairly straightforward. Simply press either volume key and expand the panel to check the media sound.

If the sound is dialed up, move on to the next solution.

Solution 3: Restart device

This is another no-brainer, something you must have already tried. However, we want to make sure we have all the basics down. So, if the first two solutions didn’t work for you, give your mobile a good, old pat on the head and perform a restart. To restart, press and hold the power button until the power menu pops up. Then, tap on ‘Restart’ to perform the act.

For mysterious reasons, many “grave” issues tend to solve themselves after a restart. So, see if you catch a lucky break with a simple restart.

Solution No. 4: Physically clean out the port

Your smartphone is theoretically the most used and abused piece of technology that you use every single day. From going to work to heading out the park, carrying your phone around everywhere is a reality, and so is the chance of dirt, grit, and grime getting lodged into the 3.5mm headphone port.

Using a can of compressed air, you can quickly give the headphone jack a blow and dislodge any particles that are blocking the path.

Tilt your Android device to the sideways to make the cleaning processes easier.

Barely insert the straw of the can of compressed air into the port itself.

Blow out the dust and lint that may be stuck in the port and repeat this process a few times.

Cleaning alcohol with a cotton swab can also be helpful in scrubbing out blockage from the headphone jack that wouldn’t necessarily come out using compressed air.

Turn off your device before you proceed to ensure that the circuitry isn’t damaged during the cleanup.

Take a cotton swab and a wooden toothpick with just a drop of cleaning alcohol.

Wipe out the insides of the 3.5mm slot with the cotton swab and let it dry out for a few minutes.

These two methods listed above should help you dislodge any of the lint or dirt that has found its way into the tiny headphone slot. However, if you can’t seem to find any physical entity blocking the headphone jack, proceed to the next solution.

Solution No. 5: Disabling secondary audio connections

Now that the audio world is moving towards turning Bluetooth into the wireless alternative to music, the headphone jack is losing its prominence. However, on devices that are powered by Bluetooth and the 3.5mm audio jack as well, there can be interference between the two that can cause the headphone jack to stop working.

You can start off by making sure that the Bluetooth module is turned off on your Android device. This is to make sure that the smartphone isn’t automatically connecting to a paired Bluetooth device which could be disrupting the headphone jack connection.

From the home screen of your Android device, head over to the Settings

Depending on your Android device, you will be able to see the Bluetooth tab right away or under the Connections

You can either choose to turn off Bluetooth momentarily or simply Unpair Bluetooth audio devices that are already connected to your phone.

Connect the headphone jack and play some audio to see if the issue has been resolved.

Solution 6: Using the SoundAbout app

The problem with the headphone jack can sometimes be a software-related glitch and not directly related to the hardware. Whether it is an app that is unable to detect the headphones connected to the device or some Bluetooth interference, there’s an app called SoundAbout that can help you resolve these issues effortlessly.

→ Download SoundAbout from Google Play Store

Download and install the SoundAbout app on your Android device.

Use the first tab to set the SoundAbout Services status to ON.

You can set the same preference for the Phone call audio tab and save it as well.

Once you exit the SoundAbout app, it will continue to run the background and reroute the audio the headphone jack manually. This should clear out any app-related audio interference that may be causing the headphone jack to stop working.

Wrapping it up

All of the solutions mentioned above have been tried and tested to fix most of the common issues that result in the headphone jack not working. However, it isn’t out of the realm of possibilities that the 3.5mm port on your smartphone could somehow by physically damaged, thus rendering it unfixable even with all of the solutions above.

The only solution left under such circumstances is to take your phone out for repair and seek a professional technician to replace the headphone jack. If your phone is still under warranty, you can have it fixed with no added cost, but either way, the headphone jack is fairly cheap to replace on most devices, although it does require expert soldering skills.

Youtube Not Working? Here Is How To Fix It

YouTube is the largest video-sharing platform in the world with a huge audience and support for long lists of devices. However, despite its immense popularity, users face a range of issues at times. From black screen to constant buffering to playback error, there are lots of problems YouTube needs to address. Nevertheless, if YouTube is not working on your device then there is no reason to worry. In this article, we have come up with 15 different methods to fix many of its nagging issues. With that said, let’s begin the article without any delay.

YouTube Not Working? 15 Methods to Fix Issues in 2023

In this section, we have mentioned 15 ways to deal with a multitude of YouTube issues. The steps are quite straightforward and you can easily resolve them on your own. Apart from that, we have also explained many steps to give you a better idea of the problems and their fixes. Now without further ado, let’s find the desired solution for you.

1. Check if YouTube is Down

Before looking for solutions, check if YouTube is down in your region. Of late, YouTube and many other online platforms have faced outages globally due to high-volume network congestion. So, if YouTube is not working all of a sudden then it’s likely down for everyone. You can find the real-time status of YouTube from here and here.

2. Clear Cache, Cookies, and Data

2. On Android, tap and hold the YouTube app and open “App Info”. Here, go to Storage and then clear both data and cache.

3. Inspect Extensions

If YouTube is not working on your computer, there is a high chance that some Chrome extensions are blocking access. To find whether extensions are the main culprit, follow these steps.

1. Open Chrome and press “Ctrl + Shift + N” shortcut key (Cmd+Shift+N for Mac) at once and an incognito window will open up. Now, open YouTube and see if it’s working. If so, then some dubious extensions are certainly creating trouble.

2. To remove such extensions, paste chrome://extensions/ in the URL bar and hit enter. Here, go through all the extensions and uninstall the ones you have no idea about. Also, try to disable as many extensions as possible to determine the culprit extension.

4. Update Chrome and YouTube App

1. On the desktop, open Chrome and paste chrome://settings/help in the address bar. Here, check for the latest update and install it right away.

2. On Android and iOS, open your respective app store and update the YouTube app. It should hopefully fix the problem you are facing.

5. Check Site Settings

1. Paste chrome://settings/content/javascript in the Chrome URL bar and ensure the toggle is enabled for Javascript. On desktop computers, Javascript is a must for running YouTube properly.

2. Similarly, paste chrome://settings/content/sound in the address bar and enable the toggle for sound settings. It will allow YouTube to play sound.

6. Check Proxy Settings

Sometimes, even after you have removed shady extensions, some changes remain in effect unless you reverse them manually. The proxy setting is one of them which extensions modify and that results in unreachable websites. Here is how to restore the proxy settings on your desktop.

7. Update Graphics Driver

If you are facing black or green screen issues while playing YouTube videos then in all probability, it’s the outdated graphics driver that is causing the problem. Here’s how to fix it.

1. On Windows PC, press “Windows” and “R” keys at once and a small Run window will open up. Here, type chúng tôi and hit enter.

8. Control Hardware Acceleration

Hardware acceleration is a great feature to play YouTube at the best quality. However, if your machine is old then disabling it will be a better option. It allows you to play YouTube at decent performance without any stutter or throttling.

However, if you have a powerful computer then do enable hardware acceleration. Open chrome://settings/system in Chrome and you will find the dedicated settings.

9. Update Date, Time, and Region

Many a time, due to incorrect timezone, date, or region set on the device, YouTube does not work and keeps showing the loading sign. So the fix is simple, just sync the time with the correct values and you will have YouTube working again. Open the Settings page of your device and look for time-related menu. Now, makes changes and restart your device, and hopefully this time YouTube works without any issues.

10. Uninstall Unknown Apps

Besides Chrome extensions, there can be rogue applications installed on your PC which can create trouble against the proper functioning of YouTube. The best way to deal with this problem is to remove unknown apps.

1. On Windows PC, open the Run window by pressing the Windows and R keys at once. Here, type “appwiz.cpl” and hit enter.

2. After that, find apps which you don’t use often and uninstall them right away.

11. Restore DNS

4. Open the Run window again and type “cmd” and hit enter.

5. Here, type ipconfig /flushdns and hit Enter. The DNS will be restored to the default settings.

sudo killall -HUP mDNSResponder

12. Reset Network Settings

If YouTube is not working on your Android or iOS device then you can try enabling the airplane mode. After a while, turn off the airplane mode and check if YouTube is working. If not, then you can reset the network settings altogether.

13. Update Operating System

It may seem unlikely but OS updates can fix most of the issues on devices. Device makers regularly push cumulative updates which are targeted to quell various types of bugs. Besides, your device also gets refreshed during the process with fresh installation and security patches.  So, if you have a pending update on your smartphone or PC, go ahead and update it right now. It might resolve the YouTube issues you are facing on your device.

14. Use a VPN

If YouTube is not working in your school or college then it’s very likely that the website has been restricted by the authority. In such cases, a VPN can help you access YouTube by tunneling the network to a different country. Also, if you live in a country where YouTube is blocked then VPN can help you evade the geographical restriction. You can find the best free VPN services from our list here.

15. Contact your Internet Service Provider

If none of the methods worked then your ISP may be at fault. ISPs are responsible for providing internet access, but they can also block access to certain websites from their end. So to resolve the YouTube issue, you should contact your ISP and ask them to lift the restriction.

6 Ways To Fix Your Iphone Flashlight Not Working

The simplest smartphone utilities, including your iPhone’s flashlight feature, can often fail to work properly in a pinch. Your trusty pocket torch suddenly fails to illuminate, and you find yourself fumbling in the dark. This guide provides the simple steps to troubleshoot and revive your iPhone flashlight when it’s not working.

1. Close the Camera App

Your iPhone’s flashlight is actually the same light used by your device’s rear-facing camera for flash photography. You can often run into a situation where the Camera app may be active in the background, preventing the flashlight from working properly. To fix this, force quit the iPhone Camera app from the app switcher:

Once you see your apps lined up like a deck of cards, swipe the Camera app out of the list by swiping upward on its app preview card. This force-quits the Camera app and may allow you to use your flashlight again.

Tip: on an Android smartphone? Learn how to turn the Android phone flashlight on and off.

2. Disable Low Power Mode

Low Power Mode on your iPhone reduces performance and disables some features to save power and extend how long your iPhone remains operable. Unfortunately, your flashlight and other power-hungry features can end up on the chopping block of disabled utilities by mistake. Follow these steps to override it.

Good to know: Low Power Mode is not an iPhone-exclusive feature. In fact, you can enable Low Power Mode on your Apple Watch to optimize it for multi-day use.

Tap the green switch next to “Low Power Mode,” and your flashlight may spring back to life.

Tip: it’s always a good idea to travel with a high-capacity power bank that can keep all of your gear, including your phone, powered on for days if needed.

3. Reboot Your iPhone

Sometimes the easiest solutions are the most effective. When in doubt, implement the age-old tech troubleshooting tip: the reboot.

For iPhones without a Home button, press and hold either of the volume buttons and the side button to bring up the power-off slider.

Drag it to the right to initiate a shutdown.

Turn your iPhone back on to see whether the flashlight is working.

Good to know: does your iPhone have a Home button? Check out our guide on how to reset any model of iPhone or iPad.

Software glitches can cause all sorts of issues, including a dysfunctional flashlight. If the previous steps didn’t do the trick, it’s worth checking whether there’s an iOS update available:

If an update is available, download and install it by tapping “Download and Install.” With a refreshed iOS, your flashlight may reactivate.

Good to know: updating your iPhone or iPad is straightforward, but updating your AirPods firmware can be a bit more challenging.

5. Reset All Settings

If your flashlight continues to be stubborn, consider a full Settings reset. Your data and content will remain untouched. This step merely resets all settings to their original state, including keyboard dictionary data, network configurations, and more.

Tip: looking for a clean slate? Discover how to factory reset your iPhone. This will erase everything on your device, so make sure you have a backup before you proceed.

6. Inspect Your iPhone’s LED Flash

If you’ve tried all of the software-related solutions, and your flashlight is still not working, it’s possible that the problem is with the hardware itself. Check the LED flash on the back of your iPhone to see if there’s any visible damage or debris. If there is, you’ll likely need to get your iPhone repaired by visiting an Apple retail store or an Apple-authorized repair provider.

Frequently Asked Questions How do I get my flashlight to work on my Lock Screen?

By default, you’ll see a flashlight icon at the bottom left of your Lock Screen. Press and hold this button to turn on your flashlight without unlocking your phone. This method is often faster than using the flashlight toggle in Control Center.

How do I switch on my iPhone flashlight without using the Control Center?

If you cannot use Control Center at the moment, Siri can step in. Trigger Siri by holding the Home button (or the side button on newer iPhone models), then say “Turn on the flashlight.” Alternatively, say “Hey Siri, turn on the flashlight.”

Can I adjust the brightness of my iPhone’s flashlight?

Yes. In the Control Center, a firm press (or a long-press on newer iPhone models) on the flashlight icon will bring up a brightness slider. From there, you can adjust the flashlight intensity by dragging your finger up or down.

6 Ways To Fix Spacebar Is Not Working In Windows

Spacebar and Enter are the most used keys on a keyboard. Imagine if these keys were to stop working – it would prove disastrous to your workflow. If you’re currently facing this issue with the Spacebar on your PC, we can help. Follow this guide to learn how to fix the problem of the spacebar and keyboard not working in Windows.

Tip: in need of a new portable keyboard? Check out these foldable Bluetooth keyboards.

Initial Fixes

Before we jump to specific solutions for the spacebar not working in Windows, there are a few general fixes you can try. Sometimes you can fix a serious-looking problem just by checking a few connections.

Make sure your keyboard is clean: dust, food crumbs, and other particles can become stuck behind your keyboard’s keys, making them unable to operate properly. If possible, remove the keys or use cotton swabs to clean between the keys. You can also use compressed air to clear off dust particles obstructing the keys.

Restart your PC: a system restart refreshes all of your system processes, eliminating any problems caused by system bugs.

Run the SFC command: SFC is a Windows utility that checks your system for any missing or corrupted files. If it finds any faulty files, it will repair them.

Roll back the keyboard driver to an earlier version or reinstall the keyboard driver: Driver updates are usually downloaded and installed automatically by Windows. You can also download them manually from the manufacturer’s official website. However, these updates might not be compatible with your system or contain bugs that require later fixes. You can roll back your keyboard drivers from Device Manager or even uninstall them, then restart your PC so that it can reinstall the drivers automatically after the boot sequence.

1. Connect the Keyboard to a Different USB Port

Most keywords connect to a PC via a USB port unless they are wireless. Even the wireless ones can sometimes connect to your PC via a USB dongle.

Image source:

Pexels

Either way, checking your PC USB ports for any dust that could interfere with the keyword connection would be helpful. Then try connecting the keyboard to a different USB port and see if the Spacebar is now operational.

2. Run the Windows Keyboard Troubleshooter

Windows has various troubleshooters that can help you diagnose your problems and effectively solve them. Conveniently enough, there is a dedicated Keyboard troubleshooter you can run.

If the troubleshooter finds problems with your keyboard, it will instruct you on how to fix it. If no problems are found, you will see the message “No changes or updates were necessary.”

3. Disable Sticky Keys and Filter Keys

The Sticky Keys feature is an accessibility feature that allows users to activate multiple keys together while pressing them one at a time. If you’ve enabled this option, Windows will assume that you’re trying to press a shortcut sequence and won’t register your Spacebar strokes.

Another feature that may cause your Spacebar not to function is Filter Keys, which, if activated, can ignore repeated keystrokes. To avoid any issues, you should make sure that both options are disabled by following the steps below:

The first two options are “Sticky keys” and “Filter keys.” Turn both off.

4. Enable Human Interface Device Service

Press the Win + R keys simultaneously to launch the Run app.

Type services.msc in the box and press Enter.

Good to know: get up to date with the latest Windows update problems and their solutions.

While it’s rare to see a Windows update cause keyboard problems, such as the spacebar not working, it can happen. If you suspect that is the issue, uninstall the most recent Windows update.

As an alternative, you can restore your system to a previous restore point. If you have created a restore point via System Restore, you can use it to bring your PC back to an earlier state when the Spacebar was still working.

6. Reset BIOS to Default

Suppose your BIOS is corrupted, or you recently made some adjustments to it, then your PC won’t be able to boot correctly, resulting in hardware problems. To undo any changes to the BIOS, you should reset it.

Turn your computer on and rapidly press the BIOS key as soon as the Windows logo appears. Depending on your PC manufacturer, this key can vary, but the most common ones are Esc, Delete, F1, F2, F10, F11, or F12.

Navigate with the arrow keys to the “Exit” tab.

Find “Load Setup Defaults” and press Enter.

You may need to confirm your choice again.

Your PC will restart, and the BIOS will return to its factory settings. Not that you will not lose any data in the process.

Tip: if you’re still using Windows 10, learn how to convert Legacy BIOS to UEFI.

Frequently Asked Questions Is there a way to assign the Spacebar function to another key?

There is no way to assign the Spacebar to another key with built-in Windows apps. However, you can try this easy workaround: wherever you want to type a space, hold down the Alt key and type “255” with your Numpad. This should leave a space when you let go of the Alt button. Note that you must ensure that your Numlock is disabled.

How do I activate the on-screen keyboard?

The easiest way to activate the on-screen keyboard is to search for it in the taskbar’s search box and select the best result. Follow the steps in this guide to activate the Windows 11 Touch keyboard.

How do I replace my Spacebar keycap?

To remove a keycap from a keyboard, gently pull it up with a small flat-head screwdriver. For the Spacebar key, try to pry as close to the center as possible. Once the key pops out, examine the hinges of the key socket and line up the new keycap holes with them. Replace the new keycap, and push gently and evenly on the four sides.

A significant part of every Windows version, Microsoft Defender, has become one of the most reliable programs to protect your device against malware.

So when an issue occurs and it doesn’t work properly or Windows 11 cannot open Windows Security, users turn to the Internet in search of causes and solutions to fix the error and get back the protection they need for their devices.

That is why we are going to take a look at the most common causes and show you how to get things on the right track.

How do I fix the Windows 11 Defender not working issue?

Before trying out more complicated solutions when your Windows Defender is not working, try out some of these quick fixes:

Restart your computer

Restart Windows Defender

1. Change the date and time 3. Enable real-time protection 4. Run a SFC scan 5. Change the Proxy Server

If you change your mind and want to give a try to a third-party tool, choose Bitdefender since it’s known for the high detection rates of the latest malware, along with unbeatable multi-layer ransomware protection.

This was our last solution for the Windows 11 Defender not working issue. Moreover, you can read more about the causes of this problem.

Why is my Windows Defender not working in Windows 11?

If you have third-party antivirus software installed on your computer, note that it might lead to certain Windows Defender errors.

Choose to use either Windows Defender or a third-party antivirus tool. Also, if you just got a new laptop, check if it came with a preinstalled antivirus trial version as this can stop Windows Defender to work properly.

Here is what Microsoft said regarding the compatibility with other antivirus products:

What happens when another non-Microsoft antivirus/antimalware solution is used? Can you run Microsoft Defender Antivirus alongside another antivirus product? The answers depend on several factors, such as your operating system and whether you’re using Microsoft Defender for Endpoint (Defender for Endpoint) together with your antivirus protection.

And if you work with programs like Flash or Java, you might need to uninstall the free security scanner which can cause some issues.

Although this might come as a surprise, another common reason why Windows Defender might not start is an incorrect time and date as most system functions are dependent on time and date.

Even more, an outdated PC can lead to many errors so we always recommend you perform a full update on your computer and on the antivirus as well.

If you’re having difficulties updating Windows Defender, you might need to install the virus definitions manually.

Windows 11 cannot open Windows Security

Expert tip:

Fore more info on what to do if Windows Security is not opening on Windows 11, check out our dedicated guide.

What does Windows Defender has to offer to Windows 11 users?

Windows Defender is pretty much the same as it was on the previous OS but there is one remarkable feature called Microsoft Defender Application Guard (MDAG) that you should know more about.

It is available for several types of devices such as enterprise desktops and mobile laptops, as well as personally-owned laptops that are managed through Microsoft Intune or a similar tool.

Designed for Microsoft Edge and for Microsoft Office, the main purpose for Microsoft’s Application Guard is to prevent developing attacks and improve employee productivity:

Microsoft Defender Application Guard (Application Guard) is designed to help prevent old and newly emerging attacks to help keep employees productive. Using our unique hardware isolation approach, our goal is to destroy the playbook that attackers use by making current attack methods obsolete.

The way the system works is quite easy to understand. For example, for Microsoft Edge or Internet Explorer, MDAG will help isolate previously defined untrusted sites, therefore, protecting your company from any attack.

If someone opens a page from an untrusted website, Microsoft Edge will open the page in an isolated Hyper-V-enabled container.

The course between the host PC and the isolated container – SOURCE: docs.microsoft

You can choose which websites, cloud resources, or internal networks are to be trusted or not. Also worth mentioning is the fact that this feature doesn’t require Hyper-V to be turned on.
