Safe Mode
Saf
e mode uses a simplied operating system on your phone with only basic functions and
pr
e-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

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.
