Phone was working fine, Twenty minutes after last use I noticed always on display was off so pressed power button, nothing.
Did all the recommended troubleshooting researched on Google and YouTube, nothing.
About 4 hours later I noticed a very dimly lit screen. Since I could see what I was doing I rebooted the phone, still dim screen. Left phone alone and about a 1/2 hour later everything back to normal. Rebooted once again and all good.
Turned in for the night thinking all was well, wrong. This morning back to blank screen. Going back to Samsung for warranty repair.
Anybody experience this before?
