Safe Mode
Safe mode uses a simplied operating system with only basic functions and pre-installed
apps available. It can be used to locate third-party apps causing system failures.
Safe Mode Functions
After installing certain third-party apps, your phone may fail to work properly. In this case,
you can enter Safe mode to check whether the problem has been caused by a third-party app
or by the system itself.
• If the system is running properly in Safe mode, the issue is likely caused by a third-party
app. In Safe mode, go to Settings > Apps > Apps, nd the third-party app in question,
and uninstall it after switching back to the normal mode.
• If the system runs abnormally in Safe mode, then the system is faulty. Back up your data
and take your device and proof of purchase to an authorized Huawei Customer Service
Center for assistance.
Enter and Exit Safe Mode
• Enter Safe mode: During the startup process, press and hold the Power and Volume up
buttons simultaneously until the selection screen is displayed. Press the Volume button to
select Safe mode and press the Power button to enter Safe mode. In Safe mode, Safe
mode is displayed in the lower left corner.
• Exit Safe mode: Restart your phone to exit.
Privacy
Permission Management
Apps may require certain permissions, such as the Location permission, in order to provide
you with corresponding services.
However, some apps may obtain too many unnecessary permissions, posing potential risks to
your privacy and information security. You can monitor the permissions granted to each app
and deny those you deem unnecessary.
Manage the Location Permission
With the Location permission, apps can obtain your location to provide location-based
services. For example, if a map app obtains the Location permission, it can provide you with
location and navigation services. You can disable the permission if you do not need these
services.
1 Go to Settings > Apps > Permission manager.
2 On the Permission manager screen, enter Location, touch the app you want to manage,
and select an option.
