Huawei's mobile phone display signature is inconsistent because the system detects the application in pure mode and adapts it, and there may be a virus. Just turn off native mode and reinstall. To turn off native mode, follow these steps:

1, click Desktop Settings.

2. Click "System and Update" at the bottom of the settings.

3. Select "Native Mode" in the system and update.

4. Click "Exit" after entering the pure mode.
