Anybody have this issue or has resolved it? Blacks out for about 0.5 seconds every 5 seconds or so repeatedly forever until reboot, then occurs again randomly shortly after. Touchscreen is non responsive during blankout event, but sound is not interrupted. Happens randomly during phone use and unable to reproduce on demand.
Also blanks out sometimes when trying to unlock, except a small window around the digital clock with non-responsive touchscreen. Locking and unlocking again sometimes resolves this.
Stopped programs, fiddled around with display settings, wireless, developer options with no success.
Edit: In my case, there was some defect in the screen assembly. Replaced it and the problem went away. Installed a new screen, worked fine until I screwed down the ribbon cable to the connector, showing the same initial symptoms. Installed another new screen but left the connector plugged in but not screwed down and it worked fine for several years and counting.
