Hello, the screen in Gionee's mobile phone GN5005 turned black. How can I change it?

1, you can select the normal mode from System Manager → Power Saving Management;

2. System Manager → Power Saving Management → Click the I number on the right side of the daily power saving mode → Close the "Dark Power Saving Theme".

3. Black screen of the mobile phone: If the operation of an application software by the mobile phone causes a black screen error, you can uninstall it first to rule out whether it is normal or not, and download it from the regular application store;

You can press on/key 15 seconds or more to restart the mobile phone, and click the left virtual key or middle key at the bottom of the screen to clear the background program of the mobile phone.

After the above operations, it is still recommended to back up the data and try to restore the mobile phone to the factory settings.
