Safe Mode
Safe mode uses a simplied operating system on your phone 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.
Use the Password Vault to Automatically Fill in the Password
Password Vault saves your usernames and passwords and
autolls them for you each time
you log in to an app. This data is hardware encrypted and stored only on your device. Huawei
does not have access to this data, and will not upload it to the Internet or server.
• Before using Password Vault, set a lock screen password for your phone.
• Password Vault is only compatible with certain apps.
Log In Faster with Password Vault
1 When you log in to an app for the rst time, your phone will automatically prompt you to
save the password. Touch SAVE when prompted.
If you accidentally touch Never save, you can still enable the autoll feature for this app
by going to Settings > Security > Password Vault > Autoll settings, and toggling on
the switch next to this app. When the switch is toggled o, the autoll feature will be
disabled.
2 If you log out of the app, the next time you log in, your device will
autoll the username
and password once you have veried your identity with your lock screen password,
ngerprint, or face ID.
When you switch to a new Huawei phone, you can use Phone Clone to transfer data in
Password Vault to your new device.
