brightness dimming on its own(even when auto brightness is off).

[nishant3009]

so here i am facing this really weird issue with my new 5s.i always keep my brightness at 100% without auto brightness.sometimes the brightness dims on its own.
happened to me quite a few times when i was playing injustice(a game), twice in settings, and again while scrolling in music player.also the battery was charged to above 50% when it occured.
any one else facing it?

Is your iPhone overheating when this happens?

I have not heard of that before.

Have you tried to reboot the phone? If not I would try that. Turn off Auto Brightness, then reboot the phone. When it comes back up check to make sure Auto is still off then slide the screen brightness all the way up.

yeah it heats up while gaming but thats normal right?coz my iphone 5 did that as well.

My LG phone dimmed when it got warm (playing games). Thats probably the case here.
