Android optimization: how to remove autorunning Samsung applications and speed up your smartphone

Smartphone owners Samsung they often encounter a problem: after turning on the device, unnecessary applications are automatically launched, slowing down the system and consuming battery power. This function, intended for the convenience of users, often becomes a source of irritation - especially when it comes to pre-installed services Samsungthat cannot be removed using standard means.

In this article we will figure out how disable autostart of applications on devices Samsung Galaxy with a shell One UI, without resorting to root access or complex technical manipulations. You'll learn about built-in optimization tools, hidden settings, and alternative methods that will help you take back control of your smartphone's performance. We will pay special attention to system applications Samsung, which are most often guilty of unauthorized launch.

It is important to understand that completely disabling autorun may affect the functionality of some services (for example, notifications or background synchronization). However, proper configuration will allow you to find a balance between performance and convenience.

Why Samsung applications launch automatically

The shell One UI from Samsung uses several auto-launch mechanisms for applications that work even after rebooting the device:

• 🔄 Background optimization: System Automatically detects "important" applications and keeps them in memory for quick access. Unfortunately, the criteria for this definition often do not coincide with user expectations.
• ⚡ Knox Services: A secure platform Samsung Knox can trigger system applications to run security checks, even if you are not using them.
• 📱 Preinstalled widgets: Many widgets (for example, Samsung Weather or Bixby) activate the corresponding applications when the data is updated.
• 🔗 Integration with Samsung account: Linking to an account synchronizes autorun settings between devices, which sometimes leads to unexpected consequences.

According to internal documentation Samsungup to 40% of system resources on new devices can be spent on background activity of pre-installed applications. This is especially noticeable on series models Galaxy A and Galaxy M, where hardware capacity is limited.

⚠️ Attention: Some applications (for example, Samsung Pay or Secure Folder) require background activity to work correctly. Disabling them may lead to failures in payment transactions or access to protected data.

Method 1: Using the built-in startup manager

Starting with version One UI 3.0 (Android 11), Samsung added a hidden section for managing autorun. To get to it:

1. Open Settings → Applications
2. Click on the three dots in the upper right corner and select Special access
3. Go to Autostart applications (on some models the item may be called Optimize autostart)

Here you will see a complete list of applications with the ability to disable autostart for each. Pay attention to the following nuances:

• 🔒 System applications (marked with the Samsungicon) can be disabled only partially - some services will still start under certain conditions.
• ⚠️ After disabling autorun for instant messengers (for example, WhatsApp or Telegram) notifications may arrive with delay.
• 🔄 Changes are not applied immediately - sometimes you need to restart the device.

Back up important data|Write down your current notification settings|Check the One UI version in Settings → About phone|Connect the charger (the process may take 10-15 minutes)-->

On models Galaxy S22 and newer, the interface of this section has been redesigned. Now applications are grouped into categories ("Social networks", "Multimedia", etc.), which simplifies mass shutdown.

Method 2: Optimization through battery settings

An alternative way to manage autorun is through the section. energy saving. This method is less radical, but allows you to limit background activity:

1. Go to Settings → Device care → Battery
2. Click on Background use (or Battery optimization on older versions)
3. Select Never optimize for critical applications and Optimize for the rest

This method has several advantages:

Parameter	Autorun manager	Battery optimization
Impact on notifications	Strong (may not arrive)	Moderate (delays are possible)
Effect on performance	Significant	Average
Working with system applications	Partial disabling	Restriction without complete shutdown
Reboot required	Sometimes	Never

For maximum effect, it is recommended to combine both methods: first disable autorun for unnecessary applications, and then optimize the remaining ones through the battery settings.

Method 3: Using ADB for deep optimization

For advanced users who are ready to work with the command line, there is a method to disable autorun via Android Debug Bridge (ADB). This method allows you to block even those components that are not available in the graphical interface.

You will need:

• 🖥️ A computer with installed drivers Samsung and package ADB
• 📱 Enabled USB debugging on your smartphone (Settings → About phone → Build number — press 7 times, then return to Settings → Developer options)
• 🔌 USB cable (preferably original)

Basic commands to disable autorun:

adb shell pm disable-user --user 0 com.samsung.android.app.launcher
adb shell pm disable-user --user 0 com.sec.android.app.launcher
adb shell cmd appops set com.samsung.systemui RUN_ANY_IN_BACKGROUND ignore

These commands disable:

1. Standard launcher Samsung (can be replaced with Nova Launcher or another)
2. Background activity of the system interface
3. Automatic launch of desktop widgets

What to do if ADB does not see the device?

1. Check if USB debugging is enabled in developer options

2. Install the latest Samsung drivers from the official website

3. Try using a USB 2.0 port instead of 3.0

4. At the command line, run adb kill-serverthen adb start-server

5. On some models, you must additionally enable debugging in the window that appears on the phone

⚠️ Attention: Incorrect use of ADB can lead to unstable system operation. Before executing commands, create a backup copy of your data using adb backup or built-in tools Samsung.

Method 4: Third-party applications for managing autorun

If the built-in tools One UI do not suit you, you can use specialized utilities from Google Play. The most effective solutions:

• 🛠️ Greenify —allows you to “freeze” applications in the background without root access. Particularly useful for system services Samsungthat cannot be completely disabled.
• 🚀 Brevient — creates “light” versions of applications, blocking their background activity. Requires configuration via ADB.
• 🔍 App Inspector —shows hidden processes and application dependencies, helping to identify the main resource hogs.
• ⚡ AccuBattery —monitors battery consumption by application and offers optimizations, including autorun control.

When using third-party utilities, consider the following points:

1. Many applications require special permissions via ADB (command adb shell pm grant package.applications android.permission.WRITE_SECURE_SETTINGS)
2. Some functions may conflict with Samsung Knoxwhich will result in warnings about security breach
3. After major updates One UI you may need to reconfigure utilities

For example, for Greenify the setup process looks like this:

1. Install the application from Google Play
2. Activate the "Aggressive Hibernation" mode in the settings
3. Add problematic applications to the hibernation list
4. Set up automatic hibernation when the screen is locked

Optimization features on different Samsung models

Autostart algorithms and the ability to configure them vary significantly depending on the device series and version. Let's look at the key ones. differences: One UI. Let's look at the key differences:

Device series	One UI version	Autostart features	Recommendations
Galaxy S23/S22	5.0+	Aggressive battery optimization, many background services Knox	Use ADB to disable unnecessary Knox components
Galaxy A54/A53	4.1-5.0	Limited options for managing autorun in the interface	Combine built-in settings with Greenify
Galaxy M33/M53	4.0	Strong memory fragmentation due to weak hardware	Disable autorun for all non-system applications
Galaxy Z Fold/Flip	5.1	Additional services for multitasking on the big screen	Leave autorun only for frequently used applications

On devices with chipsets Exynos (for example, Galaxy S23 for the European market), the background activity of system applications is usually higher than on models with Snapdragon. This is due to the features of integration Samsung Knox into the firmware.

For devices with One UI 6.0 (Android 14), a new function "Automatic optimization" has appeared, which itself determines which applications can be suspended. However, its work is not always transparent to the user. To disable automatic optimization:

1. Go to Settings → Device care
2. Click on the three dots → Settings
3. Disable parameter Automatic optimization

What to do if autorun returns after an update

One of the most common problems is resetting autorun settings after an update One UI. This happens because:

1. Samsung resets some optimization settings to default values
2. New firmware versions may add previously missing system services
3. Security updates sometimes overwrite user ADB settings

To minimize the impact updates:

• 📝 Create a text file with a list of disabled applications and ADB commands - this will simplify re-configuration
• 🔄 Use ADB scripts to automatically apply the settings after the update
• 🛡️ Disable automatic installation of updates in Settings → Software update → Automatic download
• 🔍 Check the change log before installing major updates on the forums XDA Developers

Example script for automatically disabling autorun after update:

@echo off
adb wait-for-device
adb shell pm disable-user --user 0 com.samsung.android.app.spage
adb shell pm disable-user --user 0 com.samsung.android.app.launcher
adb shell pm disable-user --user 0 com.sec.android.app.launcher
adb shell cmd appops set com.samsung.systemui RUN_ANY_IN_BACKGROUND ignore
pause

Save this file with the extension .bat and run it after each update by connecting your phone to the computer.

Alternative methods for optimizing performance

Disabling autorun is only part of a comprehensive approach to optimizing devices Samsung. Let's consider additional methods that will enhance the effect:

• 🧹 Clearing the cache of system applications: Go to Settings → Applications, select the system application (for example, Samsung Internet) and press Memory → Clear cache. Repeat for all unnecessary services.
• 🔄 Disable animation: B Developer options set Window animation scale, Transition animation scale i Animator duration to No animation.
• 📴 Deactivating Bixby: If you do not use the voice assistant, disable it via Settings → Additional features → Bixby and remove all permissions for the application Bixby Voice.
• 🔋 Setting the mode performance: In Settings → Device care → Battery → Modes and routines select Maximum performance instead of Optimized.

Pay special attention location services. Many system applications Samsung (for example, Samsung Weather or Find My Mobile) constantly request geodata, even when not in use. To limit this functionality:

1. Go to Settings → Privacy → Manager permissions
2. Select Location
3. Disable access for all unnecessary applications
4. For critical services (for example, Google Mapsset the permission Only while in use

On devices Since One UI 5.0 and newer, there's a Privacy Guard feature that shows which apps have recently used your location, microphone, or camera. This helps identify hidden system service activity.

⚠️ Warning: Disabling location services for system applications Samsung may cause problems with the feature Find My Mobilethat helps you find your lost device. Weigh the risks before disabling.

FAQ: Frequently asked questions about autorun optimization

Is it possible to completely disable all Samsung system applications without root access?

No, it is impossible to completely disable all system applications without root access. The shell One UI protects critical services, without which the device will not be able to function normally. However, you can disable autostart for most of them through ADB or built-in settings, which will significantly reduce their impact on performance.

The list of untouchable system applications includes:

• com.android.systemui (system interface)
• com.samsung.android.knox.analytics.uploader (core Knox functions)
• com.sec.phone (telephone services)

An attempt to disable these components will lead to errors in the system.

How to check which applications start when you turn on the phone?

There are several ways to track autostart:

1. Via ADB: Run the command adb shell dumpsys activity broadcasts | grep "android.intent.action.BOOT_COMPLETED" —it will show all applications that respond to the boot completion event.
2. Startup Manager application (requires root or ADB): Shows a complete list of startup applications with the ability to disable them.
3. Manual monitoring: After the reboot, quickly open Settings → Care device → Memory → Memory usage - the applications with the highest consumption were most likely launched automatically.

On devices with One UI 4.0 and newer, the built-in utility Device care shows “recently used applications” - many of them launched without your knowledge.

Will there be a reset? before factory settings solve the autorun problem?

Resetting to factory settings will return all autorun parameters to their original state, that is, the problem will not disappear, but will return to the “default” values Samsung. However, this may be useful in the following cases:

• If you have previously experimented with settings via ADB and want to start from scratch
• If system applications began to behave unstable after manually disabling autorun
• If you want to test the device's performance out of the box before applying optimizations

After the reset, you will have to reconfigure autorun, but this may be easier than correcting the consequences of incorrect changes.

Does disabling autorun affect the operation of Always On Display?

Yes, disabling autorun for system services responsible for Always On Display (for example, com.samsung.android.app.aodservice), will disable this feature. If you want to keep AOD but reduce its impact on your battery:

• Limit display time (for example, only 10 seconds after notifications)
• Disable animations and unnecessary widgets on the lock screen
• Use the "Show on schedule" mode instead of constant display

On devices with AMOLED screens (all flagship models Galaxy S i Galaxy Z) AOD consumes a minimal amount of energy, so turning it off will not give a significant increase in battery life.

Is it possible to disable autorun for Google Play Services?

Technically disable autorun for Google Play Services It is possible via ADB, but this is highly not recommended. This service is responsible for:

• Operation Google Play Market and updating applications
• Google account synchronization (contacts, mail, calendar)
• Security functions (Google Play Protect)
• Geolocation API for maps and navigation

Disabling autorun will lead to:

• Errors when updating applications
• Problems with authorization in Google services
• Incorrect geolocation operation
• Increased battery consumption due to constant attempts to restart the service

Instead of completely shutting it down, it is better to limit background activity through the battery settings, as described in Method 2.
