Smartphone manufacturers on Android often load devices with dozens of pre-installed applications - from useful services Google to unnecessary bloatware from Samsung, Xiaomi or Huawei. Many of them take up memory, consume battery power in the background and slow down the system, but it is impossible to remove them using standard methods. Are they really necessary? Spoiler: most can be safely deactivated or deletedif you know what each is responsible for.

In this article we will figure out which system applications on Android can be deleted without consequenceswhich ones should not be touched. You will learn:

  • 🔍 How to distinguish critical services from unnecessary garbage
  • ⚙️ Step-by-step guide for removal (including without root access)
  • ⚠️ List of applications, which absolutely cannot be deleted
  • 📱 Features for smartphones of different brands (Samsung, Xiaomi, Realme etc.)

Important: before any manipulation back up your data and make sure that you have access to your account Google —some actions may require a reset. If you are not sure of your actions, it is better to limit yourself to disabling applications instead of completely deleting them.

Why pre-installed applications interfere with the operation of the smartphone

Pre-installed software (bloatware) takes up space on the device tryom osnovnym prichinam:

1. Memory consumption. V srednem nenuzhnye prilozheniya zanimayut ot 1–3 GB na byudzhetnykh smartfonakh do 5–8 GB na flagmanakh Samsung ili OnePlus. For example, duplicate galleries, branded launchers or game hubs (like Game Launcher from Samsung) can weigh 100–300 MB each.

2. Background activity. Many services start automatically and consume resources. For example, Bixby on Samsung or Mi Video on Xiaomi can spend up to 5–10% battery charge per day, even if you do not use them.

3. System slowdown. The more background processes, the stronger lag multitasking. This is especially noticeable on devices with 2–4 GB of RAMwhere each extra service takes away precious megabytes.

⚠️ Attention: Some manufacturers (for example, Huawei or Oppo) block the ability to delete their branded applications via ADB or root. Before experimenting, check whether this will not violate the warranty.

How to determine which application can be removed

Not all system applications are equally useful. To understand what can be deleted and what cannot, follow this algorithm:

  1. Proverte nazvanie paketa. Open Nastroyki → Prilozheniya and find the "System" section. Imena paketov (naprimer, com.sec.android.app.launcher dlya launchera Samsung) pomogut identifitsirovat soft.
  2. Learn the permissions. Esli prilozhenie zaprashivaet dostup to SMS, calls or geolocation, but you do not use it - these are candidates for deletion.
  3. Look at the usage statistics. In Settings → Battery → Battery usage you can see which apps are consuming power in the background.

Signs of "junk" applications:

  • 📦 The name contains the words Demo, Tutorial, Hub or Launcher (for example, Samsung Free, Xiaomi GetApps).
  • 🔄 Not updated via Google Play (which means it is system and is not needed for operation OS).
  • 🚫 You've never used it, but it takes up space in the menu.

List of applications safe to delete (by brand)

Below is a table with applications that can be removed on popular smartphones without risk to system stability. Please note that on some firmware (for example MIUI or ColorOS) some of the software can be integrated into the OS - in this case it can only disable.

Brand Application name Package (name in the system) What it does
Samsung Bixby Voice com.samsung.android.bixby.agent Voice assistant (alternative Google Assistant)
Xiaomi Mi Video / Mi Music com.miui.video / com.miui.player Branded players (can be replaced with VLC or YouTube Music)
Realme/Oppo Theme Store com.heytap.theme.store Theme Store (useless if you do not use customization)
Huawei Huawei AppGallery com.huawei.appmarket Alternative application store (not needed if you use Google Play)
Any Google Play Music / Movies com.google.android.music / com.google.android.videos Outdated services (replaced by YouTube Music and Google TV)

Critical information: On smartphones with Android Go (for example, Nokia 1.4 or Samsung Galaxy A03s) deleting even “safe” applications can lead to failures. These devices are optimized to work with a minimal set of software.

What happens if you delete a system application by mistake?

At best, nothing (for example, the icon of an unnecessary player will disappear. At worst, functions like NFC, Always On Display or Quick settings. If the smartphone stops turning on, only resetting to factory settings or flashing it via Fastboot or Odin will help (for Samsung).

How to remove system applications: 3 methods

Depending on the smartphone model and version Android you can use different methods. Let's consider them from the safest to the most radical.

1. Disabling through settings (without root)

The easiest way is deactivate unnecessary apps. This will not free up memory, but will stop them running in the background:

  1. Open Settings → Applications.
  2. Select the desired application (for example, Samsung Pay).
  3. Click Disable (or Uninstall updatesif the button is active).

✅ Pros: does not require superuser rights, reversible.

❌ Cons: the application remains in memory, takes up space.

2. Uninstallation via ADB (without root, but from a PC)

This method requires a computer. with installed drivers ADB and enabled USB debugging on the smartphone. Instructions:

  1. Connect the phone to the PC and run the command line (cmd).
  2. Enter the command to check connections: 
    adb devices

    The serial number of the device should appear.

  3. Uninstall the application with the command (example for Bixby): 
    adb shell pm uninstall --user 0 com.samsung.android.bixby.agent

List of popular commands for ADB:

  • 📋 View all installed packages: 
    adb shell pm list packages
  • 🗑️ Uninstall the application for the current user (without root): 
    adb shell pm uninstall --user 0 [package_name]
  • 🔄 Return the application (if something went wrong): 
    adb shell cmd package install-existing [package_name]
⚠️ Attention: On some devices (for example, Xiaomi c MIUI 14+the command uninstall may not work due to manufacturer blocking. In this case, only root or a reset will help. settings.

3. Removal with root access (for experienced)

If you have root, you can permanently remove applications using a file manager (for example, Root Explorer) or the command: 

su

rm -rf /system/app/[package_name]

⚠️ Risk: Invalid removal of system files may lead to "brick" (inoperability) of the device. Before doing this, be sure to make a backup via TWRP or OrangeFox.

💡

Before deleting via ADB or root, check whether the application is a dependency for other services. For example, deleting com.google.android.gms (Google Play Services) will lead to the crash of most applications, including Gmail and Maps.

Which applications CANNOT be deleted (critical list)

Some system services necessary for stable operation of Android. Deleting them will lead to errors, the inability to make calls, connect to the network, or even turn on the smartphone. Here's what you can't touch:

  • 📞 Phone and contacts:
    • com.android.phone (call module)
    • com.android.contacts (contacts)
  • 🌐 Network and Internet:
    • com.android.providers.telephony (SIM cards)
    • com.google.android.gms (Google Play Services)
  • ⚙️ System components:
    • com.android.systemui (system interface)
    • android (OS kernel)

How to check if an application can be uninstalled? If there are words in its name framework, service, provider or core —it’s better not to take risks. Also avoid anything related to:

  • 🔋 Power management (com.android.server.power)
  • 🔒 Security (com.android.keystore)
  • 📶 Communication modules (com.qualcomm... for Snapdragon)
💡

Even if the application seems unnecessary, but its package begins with com.android. or com.google.android., you can delete it only after checking it in reliable sources (for example, on forums XDA Developers or 4PDA).

Features for smartphones of different brands

What to do if something breaks after deleting

If, after manipulating system applications, the smartphone begins to glitch, does not turn on, or has lost important functions, use these tips:

  1. Return the application via ADB: 
    adb shell cmd package install-existing [package_name]
  2. Reset settings: Restore factory settings via Recovery Mode (press Power + Volume up when turning on).
  3. Reflash the device: If the smartphone does not turn on, download the official firmware from the manufacturer's website and install it via Odin (Samsung), Fastboot (Google Pixel) or SP Flash Tool (Mediatek).

Typical symptoms after incorrect removal:

  • 🔄 Endless loading (bootloop).
  • 📵 Lack of network or mobile data.
  • ⚙️ Not working Settings or Notification panel.
  • 🔋 Rapid battery drain (if the power management service is removed).
⚠️ Attention: If you deleted something critical (for example, com.android.phone), but there is no backup, you may need to reflash it via EDL mode (for Qualcomm) or contact a service center.
💡

Before experimenting with system files, always check whether there is a custom recovery (TWRP) and stock firmware for your smartphone model. This will save the device in 90% of cases of unsuccessful removal.
