How do I Know whether my Phone's Issues are Affected by Downloaded Apps or not?
You can boot up your device in Safe mode if you wish to troubleshoot whether downloaded apps are causing problems to the device or not. Safe mode will load only basic system software.
Turn Safe Mode On
When the Lock screen is displayed, 'Safe mode' will be displayed on the lower-left corner of the screen.
Turn Safe Mode Off
To exit Safe mode, please restart your device.
If your device is working properly in Safe mode, please uninstall downloaded apps or updates the apps.
