There are two methods to disable the auto-restart function Method 1: From the home screen swipe up or down to access the App Screen > Setting > General Management > Reset > Auto Restart > To Turn OFF auto-restart slide the slider toward the left. Method 2: Go to 'Settings'>>Tap on 'Battery and device care'>> Tap on Three dots>>Tap on 'Automation'>>Disable 'Auto-restart at set times' if enabled
If you are facing this issue after installing any new application then uninstall that application. Navigate to the Apps screen and tap on Settings>>Tap on Apps>>Tap on the desired app>>Tap on Uninstall>>Tap on OK
Reset settings: From the home screen, click on Settings>>General Management>> click on reset and then reset setting.
