What if there is a black screen when the mobile phone plays video?

If the screen appears black when the mobile phone plays video, I suggest you.

Replace the video player

Verify that the Internet is used for online video viewing, and try to change the video player.

Download third-party players

Try downloading another third-party video player.

Clear player data

If this problem occurs in your own player, please: 1). Try playing another video. 2). Try to clear the video player data.

Backup data

If not, please back up the data (contacts, text messages, photos, etc. ) and try to restore the factory settings.

Contact the after-sales service center

If the problem still exists, it is recommended that you take the machine, purchase invoice and warranty card to the local Samsung after-sales service center for testing.
