How to prevent pre installed apps in phones?

There are a few things you can do to prevent pre-installed apps from crowding your phone.
First, take a look at your app drawer and see which apps you actually use. If there are a bunch of apps that you never use, you can uninstall them. This will free up some space and prevent them from running in the background and using up resources.
If you can't uninstall an app, you can try disabling it. This will prevent it from running and using up resources, but it will still be on your phone in case you ever need it.
You can also use a launcher to customize your app drawer and only show the apps you want. This can help declutter your phone and make it easier to find the apps you need.

Finally, keep in mind that pre-installed apps are often updated automatically, so you may not be able to completely get rid of them. But by taking these steps, you can reduce their impact on your phone and keep them from taking up too much space.
Every Android device comes with a number of pre-installed apps. These are apps that Google or your smartphone manufacturer wants you to use. You might find some of them essential, but what about the pre-installed apps that you never use?

These unwanted Android apps are called “bloatware” because most of them cannot be removed through the traditional uninstallation process.
Here, we will show you an alternative method to uninstall pre-installed apps on Android without rooting your device. But first, let's try disabling the default apps.

 Disable Pre-Installed Apps

Some smartphone manufacturers allow you to disable pre-installed apps. This won't remove the app from your smartphone, but the app will stop running in the background and will no longer show up in the app drawer.
To disable an app on your Android device, head to Settings > Apps & notifications > See all apps. Now choose the app you want to disable and tap on the Disable button. This method can vary depending upon the Android device you’re using.
If you don’t see the Disable button, or see an option that reads, “Uninstall updates”, it means that you cannot disable the app. You can remove it by following the method below.

How to Remove Bloatware From Android

To remove pre-installed apps from your Android, you will need to install ADB on your device. See our guide on how to use ADB and Fastboot on Android for more on how to do this. If you are running Windows, you can download the minimal ADB setup from xda-developers.com for ease of use.

Before we move forward, you also need to enable USB debugging on your Android device. Go to Android settings > About Phone then tap several times on the Build number to unlock the Developer options. Now, find USB debugging in the Developer options—which you'll usually find under System or Additional Settings—and enable it.

Once you have ADB running on your system and USB debugging is enabled, follow the below steps to remove bloatware from Android:Once you have ADB running on your system and USB debugging is enabled, follow the below steps to remove bloatware from Android:

 Connect your Android device to the PC using a USB cable.

Open the command-line on your PC.

Type adb devices in the command prompt and press Enter. You will get a prompt on your smartphone asking you to authorize a connection with the computer. Tap on OK.

Again, enter the command adb devices. You will now see your device under “List of devices attached”.

Type adb shell and press Enter.

     Type pm uninstall -k --user 0 <package name> to uninstall your unwanted app.

Package name in this case refers to the name of the file that contains the app you're uninstalling. How do you know what that is? On your Android device, download a free app called App Inspector from the Play Store. You can then use this to find the package name of the app you want to remove.

You can also re-install a default app using the command: adb shell cmd package install-existing <name of package>.
