Suggested January 2024 How To Check If Carrieriq Tracking Software Is Installed In Your Android Phone

The hottest news lately has to be the discovery of the CarrierIQ software residing in most Android phones. If you are still not aware, CarrierIQ is a tracking software that can track almost every single bit of information in your phone, including the characters you typed in your keyboard, the website you visited, the information stored in your phone and many more, without your knowledge and permission. Unlike most third party app where you have to install manually, this software comes in-built in the phone and since it lies at the kernel of the OS, it can’t be removed easily.

For those of you who are not sure if your Android phone comes with this tracking software, simply go to the market and search with the term “carrierIQ detector“. It should return a big list of CarrierIQ detector app that you can install to check if your phone is infected.

I tried with the Lookout CarrierIQ Detector and this is what it shows on the screen when you run the app.

What should I do if my phone is infected?

As the CarrierIQ is embedded in the kernel level, there is no way to remove the tracking software within the OS. If you are technical competent and are willing to void your warranty, the only way to remove CarrierIQ from your phone is to root your phone and replace the existing ROM with a custom ROM. Popular third-party ROMs such as Cyanogenmod and MIUI are community-based and are safe from CarrierIQ’s clutches.

Note: As there are too many Android phones, each with their own rooting method, we won’t be discussing in detail the method to root your phone and install custom ROM.


Apple admits that the CarrierIQ is included in iOS as well, but they do provide you with a way to turn it off.

That’s it.

How To Tell If Your Android Phone Was Infected

The possibility of getting infected on Android has been taken seriously ever since malware started appearing on Google Play. The market is flooded daily with different malicious applications, mainly because Google doesn’t regulate its ever-growing market sufficiently. This isn’t exactly good news for you, since your phone may behave strangely one day due to an app. I got a wake-up call recently when my phone was almost infected as a website automatically downloaded an app into it. For this reason, I decided it’s a good a day as any to talk about how you can tell if you’re infected, and what to do to prevent it from happening.

1: Your Calls Act Funny

If you’re calling someone and the conversation suddenly stops, try calling another number. Maybe the problem is on the other end. Call a land line. If you still get dropped calls once in awhile, you’re probably infected by malware (unless you’re calling from a tunnel). Malware has a tendency to interfere with calls when it uses your cellular antenna. Sometimes, it even records what you’re saying on the phone. This is a massive breach of privacy that must be stopped immediately.

2: You Get a Few (or Many) Surprises in Your Bill

The day you get your phone bill, pay close attention to it. If you see a spike in SMS activity or data usage that shouldn’t be there, an app is probably sending messages or relaying data without your knowledge. Some of them send messages just once in a while, making it difficult to distinguish. Ask people on your contacts list whether they’ve seen strange messages from you. If you’re lucky, some people might actually reply to the SMS sent by the malware, demonstrating that something is sending messages on your behalf without your knowledge. Android might even show the message in the conversation window.

3: The Phone has Enormous Amounts of Lag

Just like viruses in Windows, malware in Android can cause significant drops in performance on the platform you’re using. You’ll either find the phone nearly unusable in the most extreme cases, or you’ll have difficulty switching from an app to your home screen as smoothly as you’re used to. This kind of performance drop is experienced either by a rogue application acting weirdly or malware exploiting your phone’s processing power heavily.

How to Stop and Prevent Malware on Android

First of all, you should have a competent antivirus app installed on your phone. I’d recommend Avast! or Lookout. This will help you get rid of whatever malware you might have right now. To prevent any infections, take these precautions:

When looking at an app on Google Play, check the reviews. If you’re lucky, a few people will come out and say that it’s malware. How many people downloaded the app? If it’s not popular enough for at least 1,000 reviews, you’re taking a higher risk.

How To Tell If Your Phone Has Been Hacked?

If you see suspicious things happening on your phone, like a new app you didn’t install or charges on your bill that don’t make sense, it’s possible that it’s been hacked.

Some of the most common methods hackers can use to hack your phone are:

Social engineering: Another common method hackers use is social engineering, which mainly exploits the human aspect. They manipulate our psychology/ emotion to get the required information for the attack. It could be as simple as asking for a password straight up for Wi-Fi or an OTP code.

Keylogger: Hackers can use keylogger software to track and record every keystroke you type, including account login credentials. Such programs get into your devices through malicious apps or any other form of malware.

Nonetheless, there are still some subtle signs that your phone is likely hacked or infected with malware.

If you see any unrecognized apps, you shouldn’t open them and consider uninstalling them immediately for your safety.

The major reason someone would try to hack your phone is for financial benefit. So, if you find any unknown purchase made from your phone, check the SMS alerts sent by your digital wallet or banking app. Furthermore, you can also download the entire list of your financial statements to review all your purchases.

If you get a message such as “Your phone is locked” or similar, your phone is probably hacked. In these cases, you cannot access your files, media, or documents and could be asked for a ransom to retrieve them. These are special types of malware called ransomware and are hard to get rid of. Also, there’s no guarantee that you will get your files back even if you pay the ransom.

A phone’s performance drops gradually after a certain point in time. However, it isn’t normal if the performance drops significantly and your phone suddenly becomes too sluggish.

Similarly, your phone can heat up abnormally even when you don’t seem to have any open applications, and the battery drains too quickly. Also, your phone may behave erratically and restart multiple times for no reason.

All the signs above indicate that a background process, most likely a virus/malware, is running in the background, hogging up your memory and taking control of your phone.

Sometimes your call history looks different, and unknown phone numbers exist without your knowledge, even when you haven’t actively used your phone. Also, some messages have been deleted, or there are unknown text messages. In these cases, your phone might have been in the control of the attackers. Or the text message could be malicious.

These days, scammers use this tactic to request money from people on your contact list, impersonating you when in reality, the money is being transferred to them.

In some cases, you are logged out of any account automatically on your mobile phone. And when you try to log in, you keep getting an error message like “Incorrect password” even though you entered the correct one.

If your password has been compromised, your phone might be hacked, and its passwords might have even been leaked online by hackers.

If you ever feel like your mobile data is being consumed more than usual, a third person might be using them to secretly upload your private information to their server. In such cases, your phone has abnormally high data consumption even when you haven’t utilized any data.

On Android devices, you can view the data usage graphs through the Settings app and check if the data traffic is unusual.

Instead of being a victim of a possible scam or hack, you should try to avoid/prevent them by being aware of the signs like the above. To prevent such incidents, you can do the following things.

Passwords are the key component when it comes to your device security. Whether it be your lock screen or your Google Account, the perpetrator can do severe harm if they get their hands on the passwords.

Therefore, you should always use a strong password that contains a combination of all kinds of characters; symbols, letters, numbers, etc. Also, consider using a longer password as it can withstand most brute-force attacks than a shorter one. To easily manage passwords, consider using a password manager.

On the other hand, don’t use the same password for every site you sign up for. It’s because if one of the passwords gets breached, others can also get compromised.

While a strong password is a great way of keeping your device safe from hackers, you should also consider turning on two-factor authentication. This adds an extra layer of security by requiring you to provide multiple passwords/information before you can finally log in to the account.

Public Wi-Fi is one of the most exploited methods used by cybercriminals to hack your smartphones. Such Wi-Fi connections are generally unencrypted and thus easier for them to hack and exploit.

Hence, you should avoid using public Wi-Fi, and in case of emergency, access the Internet through a VPN for a secure connection. Also, refrain from performing any financial transactions while using such Wi-Fi.

Another common way a hacker can get his hands on your device is when you install malicious apps from an external source. Therefore, you should only install apps from the official Play Store/ App Store.

If you have a habit of leaving your phone unlocked, other people can easily access its contents. So, consider signing out of your social media account when not in use. Or, at least secure your phone with a password/PIN to prevent it.

If your phone is running on an older version or has an outdated app, it may contain several bugs and issues which can be exploited by the bad guys. Such weaknesses are even circulated among illegal hacker forums, which means phones with older OS are easy prey for them.

Phone manufacturers and app developers constantly release newer versions of the app to fix the device’s previous vulnerabilities with the latest security patch. Therefore, you should always keep your phone and the apps updated to avoid such risks.

While some people root their Android phone for further customization, it isn’t recommended. Doing so voids the warranty, and you may not get any security updates for the device, which makes you vulnerable to malicious exploits.

Although saving passwords and enabling autofill on a browser is easier, it’s an unsafe practice. Any person, not necessarily a hacker, with physical access to your phone can easily log into websites and view your personal information.

You should always try to avoid getting into situations where your phone gets compromised in the first place. However, if you somehow fall into the trap and suspect your phone is hacked, you should consider doing the following things.

In case any of your accounts are breached, you should immediately change all their passwords. And, if the Google account is compromised on your Android device and you cannot change your password, you can reach out to Google Support.

If your phone is hacked, it most likely contains malware. Therefore, install a reliable antivirus app and use it to scan and remove all the potentially harmful software or viruses on your phone.

Resetting your phone clears all your phone contents and restores it to its initial configuration. All the malware or viruses are also wiped off along the process. However, consider backing up your files and other contents before doing so.

The moment you notice any suspicious activity on your phone, especially if you get a notification of an unknown purchase, you should immediately contact your financial institution. Then, ask them to freeze your accounts so that you can prevent further financial losses.

How To Check If A Matrix Is Invertible Or Not In R?

If the matrix is singular then it is not invertible and if it is non−singular then it is invertible. Therefore, we can check if a matrix is singular or not. We can use is.singular.matrix function of matrixcalc for this purpose. For example, if we have a matrix called M then to check whether it is invertible or not, we can use is.singular.matrix(M).


Loading matrixcalc package and creating a matrix −

What Is Android System Intelligence, And Why Is It On Your Phone?

Edgar Cervantes / Android Authority

Your Android phone has a host of system apps and services, all with their own tasks. One such app is Android System Intelligence. Google has chosen to name the app rather broadly and vaguely, and it’s not immediately clear what it is, what it does, and why it needs so many permissions. Here’s what you need to know about the Android System Intelligence app and whether you can remove it from your Android smartphone.

Android System Intelligence is a system component within Private Compute Core that powers intelligent features across Android while keeping your data private.

In short, Android System Intelligence is a system app that helps make your smartphone “smart.” The name is rather vague and opaque, but that is due to the “miscellaneous” nature of the features it encompasses.

What does Android System Intelligence do?

Ryan Haines / Android Authority

But what does this app actually do? As mentioned, Android System Intelligence powers a bunch of features.

Live Caption: Automatic captions for media.

Screen Attention: Your screen won’t turn off while you look at it (present on the Pixel 4).

Smart Autorotate: Detects the orientation you hold your phone in.

Improved copy and paste: It makes moving text from one app to another easier.

App predictions in the launcher: Suggests the app you may need next.

Action buttons to notifications: For example, the action buttons could add directions to a place, help you track a package, or add a contact right from the notification.

Smart Text Selection across the system: Makes selecting and acting on text easier. For example, on an address, you can long-press to select it or tap to check directions.

Linkify text: Turns text in apps into links.

Live Translate: Translates live text conversations and video.

App Search: Find a specific app.

Assistant Voice Typing: Dictate text through your voice with Assistant voice typing on Gboard.

Now Playing: Recognition of music around you.

Adding boarding pass with a screenshot: You can add a boarding pass to Google Pay with a screenshot.

Note that not all Android devices will get all the features. Some features are Pixel-specific, and some require other hardware.

Can I uninstall or disable Android System Intelligence? How to uninstall or disable Android System Intelligence from your Android phone

Android allows you to disable the Android System Intelligence app. Here are the steps for the same:

Here, you will find the listing for Android System Intelligence.

Disabling the app is fairly harmless, and you can re-enable it in the future.

Since Android System Intelligence is part of the Android system, you cannot uninstall it like a regular app. If you really want to uninstall it, you will need to root your phone or use shell commands to uninstall it.

Here’s the command that you would need to run on adb on your computer to remove the app on your phone:


adb uninstall chúng tôi the app is also fairly harmless, with the caveat that the above features will not work. Thankfully, removing the app does not impact your phone’s telephony or other critical functions.

Why does Android System Intelligence need location permissions?

Google does not specifically disclose why Android System Intelligence needs location permissions. However, Google does mention that the app uses system permissions to provide smart predictions. The example that Google says relates to the contacts’ permission, but we can also extrapolate the same to the location permission. For example, the app suggestion feature will need access to your location to smartly present ride-sharing apps when you are out and about.


Certain smart features like Now Playing, Live Caption, Live Translate, and more will stop working if you disable Android System Intelligence. However, your critical phone functions will continue working.
