Huawei P8 - Why Cant I Install some Apps and Why Does My Phone Prompt Repeated Permissions

16.1.6 Why can't I install some apps and why does my phone
prompt "repeated permissions"?
The repeated permissions function is used by the Android 5.0 system to restrict third-party
apps in customized permissions, thereby standardizing the permission app of apps and
protecting data security of users. The Android 5.0 system checks the applied permissions
when you install apps. If the new apps apply for the permissions customized by other apps
and the signatures are different, the system prompts for repeated permissions and exits the
installation. Huawei will try to promote the app developers to rectify the design to avoid
security risks.
16.1.7 Why is a third-party app still running after I close all the
apps at the touch of a button?
1. Go to Settings > Manage apps > Running. Select the corresponding app and forcibly
stop it.
2. You can also open the application and exit it.
16.1.8 Why do I have to delete the pre-installed application twice
and why does my phone always display a message telling me that
the application can't be deleted at the first time?
The pre-installed application and its updates are not saved in the same directory. When you
delete the application for the first time, you have only deleted its updates and the application
icon will appear on the home screen again. If the application can't be uninstalled, your phone
will display a message telling you that the application can't be deleted at the second time.
16.1.9 What can I do if the third-party application can't access my
location?
To solve this problem:
1. Go to Settings > Location access and turn on Access my location.
2. Go to Settings > Permission manager > Access location info and set the permission of
the application to Allow.
16.1.10 Why isn't the system font size applicable to the third-party
application?
You can set the font size in the settings menu of the third-party application.
16.1.11 What can I do if there isn't a pop-up window for a new
SMS when I am using an application?
On the Messaging screen, touch the menu icon then Settings, and select Notification.
