My Flip 6 screen has gone completely black. I could get it back with a hard reset (volume down start button) But not anymore. . It was random at first but now it's full time. The cover screen still works. I've tried all of the tricks mentioned in a few YouTube videos, nothing. It appears this is a Samsung wide problem. Many people are saying that when they take the phone in for repair they are being charged hundreds of dollars because Samsung says they must have damaged the phone. Anyone else having this black screen problem?
