How to stop a process on Android: from simple methods to forced termination

A ​​frozen application, endless loading or unresponsive system process - almost every owner of an Android device has encountered these problems. Unlike a PC, where you just need to press Ctrl+Alt+Del, on a smartphone the algorithm of actions depends on the type of process, OS version and even the device manufacturer. Incorrect manipulations can lead to data loss, system failure, or even a “brick” (complete inoperability of the gadget).

In this article we will look at all current methods of stopping processes from standard Android tools to advanced methods using ADB and Safe Mode. We will pay special attention processes that are not terminated through the "Recently Used" menuincluding system services and background tasks from the manufacturer (for example, MIUI, One UI or ColorOS).

1. Standard closing through "Recently Used"

The most obvious and safest method is closing the application through the multitasking menu. However, it does not always work: some processes (for example, system ones or with administrator rights) may be automatically restarted.

How to do this:

• 📱 On most smartphones, swipe up from the bottom and hold your finger in the center of the screen (or press the square navigation button).
• 🔄 Find the frozen app card and swipe it up or to the side (depending on the Android version).
• 🔍 On some devices (for example, Xiaomi or Samsung) you may need to click on the "Pin" or "Close All" icon.

If the application does not close or restarts immediately, move on to the next method. This is a signal that the process is running in the background or has elevated privileges.

2. Forced stop through Android settings

This method is suitable for any applications, including system ones, but requires manual intervention. Important: some processes (for example, com.android.systemui) after stopping can lead to a temporary crash of the interface.

Instructions:

1. Open Settings → Applications (on some devices - Settings → All applications).
2. Find the desired application in the list (use search if there are many).
3. Tap on it and select Forced stop (or Stop).
4. Confirm the action in the window that appears.

On devices with MIUI (for example, Redmi or POCO) the path may differ: Settings → Applications → Manage applications → [Select application] → Stop. On Samsung s One UI Sometimes you first need to click on the three dots in the upper right corner and select Show system processes.

3. Using Task Manager

Many manufacturers build their own dispatcher tasksinto the firmware, which allows you to terminate processes more flexibly than the standard Android tool. For example, on Samsung it Device Care, on Huawei — Phone Manager, and on Xiaomi — Security.

Interface examples:

⚠️ Attention: Task managers from manufacturers often aggressively close background processes, which can disrupt notifications or synchronization. Do not use “optimization” too often - Android manages memory on its own better than most “cleaners.”

4. Ending processes via ADB (for experienced users)

If standard methods do not help, you can use Android Debug Bridge (ADB) —a debugging tool that allows you to manage processes via the command line. This method requires connecting the device to a PC and enabling USB debugging.

Step-by-step guide:

1. Install ADB Tools on your computer.
2. Enable on your smartphone Settings → About phone → Build number (tap 7 times to activate Developer mode).
3. Return to Settings → System → Developer Mode and enable USB Debugging.
4. Connect the device to the PC and enter in the command line:

   adb devices

   (your device should appear).

5. Get a list of active ones processes:

   adb shell ps -A | grep "process_name"

   For example, for Facebook:

   adb shell ps -A | grep "com.facebook"

6. Turn the process by PID (identifier):

   adb shell kill -9 [PID]

   For example:

   adb shell kill -9 12345

To stop system applications (for example, com.android.systemui), you may need the command:

adb shell am force-stop com.android.systemui

⚠️ Attention: Commands kill -9 and force-stop can lead to temporary system instability. Do not terminate processes named zygote, surfaceflinger or android.process.acore are critical components of Android.

5. Safe Mode to stop system processes

If a process is associated with a virus, malware, or firmware glitch, it may not be possible to stop it normally. In such cases, it will help Safe Mode - a mode in which only standard system applications are loaded.

How to enable Safe Mode:

• 🔄 On most devices: hold down the button Power, then tap and hold Shutdown (a prompt will appear to switch to Safe Mode).
• 📱 On some models (for example, Samsung): press Power + Volume Down until logo.
• 🔌 On devices with a non-working screen: connect the charger, then press Power + Volume Up for 10 seconds.

In Safe Mode:

1. Check whether the problem has disappeared (if so, third-party software is to blame).
2. Go to Settings → Applications and remove or stop suspicious processes.
3. Reboot your device to exit Safe Mode.

6 will help. Alternative methods: Termux and third-party applications

For users who do not want to connect to a PC, there are ways to end processes directly from the phone:

Method 1: Termux (terminal for Android)

1. Install Termux from Google Play.
2. Enter the command to obtain superuser rights (if you have root):

   su

3. View the list of processes:

   ps -A

4. End the process by PID:

   kill -9 [PID]

Method 2: Third-party Task Killer

Applications like Greenify or Advanced Task Killer allow you to manage processes without ADB. However:

• ⚠️ They require root access for full operation.
• ⚠️ They may conflict with the Android memory management system (especially on new versions of the OS).
• ⚠️ Some antiviruses (for example, Avast) block them as potentially dangerous.

⚠️ Attention: Using Task Killer on Android 10+ and newer is often useless due to background activity restrictions introduced by Google. The system itself optimizes memory, and forcing processes to close can only increase battery consumption.

Common errors and how to avoid them

Many users make critical mistakes when trying to stop processes. Here are the most common:

• 🚫 Closing system processes without understanding the consequences. For example, stopping com.android.phone will lead to network loss.
• 🚫 Using Task Killer on a permanent basis. This breaks Android's memory management mechanisms and increases the load on the processor.
• 🚫 Forced stop of the launcher (com.android.launcher). This will cause the interface to reload and loss of widgets.
• 🚫 Deleting the system application cache. May lead to malfunctions of the camera, calls or GPS.

If, after stopping the process, the device begins to slow down or overheat, follow these steps:

1. Restart the smartphone.
2. Check the battery temperature in Settings → Battery.
3. If the problem persists, reset the settings to factory settings (after saving the data).
