Settings • When using three-key navigation, touch to access the recent tasks screen, and touch on an app preview. To unpin, touch and hold . Safe Mode Safe mode uses a simplified 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 device 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, find 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 authorised Huawei Customer Service Centre for assistance. Enter and Exit Safe Mode • Enter Safe mode: During the startup process, short press the Power button continuously until the selection screen is displayed. Touch the 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 device to exit. Privacy Permission Management Apps may require certain permissions, such as the Location permissions, 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 > Permissions. 175
