Smartphones on Android are often clogged with unnecessary applications even at the purchase stage. Manufacturers install dozens of preloaded apps - from branded launchers to little-used services Google. Over time, users add their own applications, many of which end up abandoned. As a result, the device begins to slow down, and free disk space melts before our eyes.

But not all apps can be deleted without consequences. Some applications are critical to system operation, while others simply take up space but do not impact performance. In this article we will figure out What apps can be safely removed on Androidhow to distinguish system files from unnecessary software, and what to do if something goes wrong after deletion. We will also consider ways to clear the cache, disable built-in applications, and alternative methods for optimizing memory.

Why are there so many unnecessary apps on Android

Even on a new smartphone, the user finds dozens of installed applications that he will never use. Where do they come from?

1. Bloatware from the manufacturer. Companies like Samsung, Xiaomi or Huawei adding their own branded services - from alternative browsers to cloud storage. For example, devices Samsung Galaxy are pre-installed Samsung Health, Samsung Pay, Bixby and other apps that many users do not use. On Xiaomi this can be Mi Browser, Mi Video, GetApps other utilities.

2. Google services. Even on “pure” Android (for example, on Pixel) there are applications that not everyone actively uses: Google Play Music (already closed, but remains on older devices), Google Duo (replaced by Google Meet), Google Tips (Google Tips) and others. Some of them duplicate functions or are simply not needed by most users.

3. Applications from telecom operators. Mobile operators (MTS, Beeline, MegaFon, Tele2) often install their own apps for managing tariffs, viewing balances or accessing entertainment content. For example, My MTS, Beeline TV or MegaFon TV. These apps take up space and can run in the background, draining your battery.

4. Residual files after updates. When updating the OS or applications, sometimes old versions of apps, caches or temporary files remain. They are not visible in the main list of applications, but take up disk space.

⚠️ Attention: Some pre-installed applications cannot be removed using standard means, but they can disable. This will free up space and stop background activity, but the files will remain in the device memory.

Which applications can be deleted without risk

Before you start cleaning, it is important to understand which apps do not affect the operation of the system and can be deleted without consequences. Below is a list of categories of applications that you can get rid of.

Install drivers for your device on your PC

Enable developer mode and USB debugging

Download and configure ADB (Platform Tools)

Check the name of the application package

Create a backup copy of important data-->

Method 4: Using third-party cleaning apps

There are applications that help find and remove unnecessary software. them:

  • 🧹 SD Maid - finds residual files, cache and unnecessary applications.
  • 🗑️ Files by Google - built-in memory cleaning tool.
  • 🔍 App Inspector - shows detailed information about applications, including system ones.

How to disable system applications that cannot be deleted

If an application cannot be deleted, you can disable. This will stop it from working, hide the icon from the menu and free up some memory. However, the application files will remain on the device.

  2. Select the desired application (for example, Bixby on Samsung).
  3. Click Disable (or Turn off).
  4. Confirm the action.

After shutdown:

  • ✅ The application will stop working and updating.
  • ✅ Background activity will stop (saving battery power).
  • ✅ The icon will disappear from the menu (but will remain in the list of applications in the settings).
  • ❌ Application files will remain on device (this will not free up a lot of space).

Some applications cannot be disabled using standard means. In this case, it will help ADB:

adb shell pm disable-user --user 0 package name

To enable the application again, use:

adb shell pm enable package name
