Hello everyone. Today I was outside reading some articles on my S23 Ultra, when all of a sudden, the screen was so dim I could barely read it. The brightness slider said it was optimized for the brightest display possible. Does anyone know why this happened?

To answer your question, you should never leave your phone in direct sunlight.

@kmb1 It may have been because your S23 Ultra got warm and screen brightness was reduced so that it wouldn't overheat. Or maybe the battery was low and triggered some battery saving techniques.

It did get noticeably warm in my hand, and my battery is almost full. After I brought it inside for a few minutes and took it back outside, it stayed bright again, so I believe your first thought was correct.
How would you know how long you could keep the phone in the sun before this started happening? I'm assuming there's no way to get around this auto - dimming, either, since it's obviously there to protect the phone. Thanks for the info.

Right. I grew up in west Texas, so I learned early on to never leave ANYTHING in the sun lol. But in this case, I was holding the phone the entire time; I apparently lost track of time (that kind of thing happens when you get my age). Thanks!

I assume you don't have the display set to automatically adjust to ambient light?

Right. When this happened, I turned it off, and then back on again, but it didn't make any difference. I'm sure I just had it in the direct sunlight too long. Everything's back to normal now. Thanks!
