- Having too many apps running at the same time may cause a black screen. You may use Phone Manager to clean and speed up your phone, and close unnecessary apps that are running in the background.
- Please clean up the app’s data and uninstall the app. Then download the app from an official channel, reinstall it and try again.
- Please back up important data, restore your phone to factory settings and try again.
If the issue persists, it might be because the app is incompatible with Android 6.0. Please wait for an updated version of the third-party app, or replace it another similar app.
