iPhone 6 : Auto Brightness Issue After Updated To iOS 8.3

there is a trick which is a some kind of workaround... but nevertheless there is something wrong with that feature

but symptoms first (at least for me)

- auto brightness is on

- moving from dark room to bright room - always works

- moving from bright room to dark room - never works

====

What works for me is to just turning the screen off and turning it on again when I am already in a dark place. Then brightness is adjusting itself as it suppose to, and I always need to do that.

... maybe this is a "feature" which suppose to work like that by design 😝 😉

Cheers!

You can't downgrade iOS levels.

I am having no problems with Auto Brightness on iOS 8.3 so I doubt that it is the cause of your trouble.

Try the standard troubleshooting steps in this order:

Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.

Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10-15 seconds). No data will be lost.

Restore: Connect your device to iTunes on your computer, backup, and then select Restore to Factory.

See here for more details on restore: https://support.apple.com/en-us/HT201252

If none of these work your device may have developed a hardware problem. Contact Apple Support: http://www.apple.com/contact/

I got this symtom too. It,the auto brightness in ip 6, is actually NOT "not working" at all, but it's not stable. When you're about to move from bright place to dark place, sometimes it worked as expected, sometimes it do NOT reduce brightness to adapt to the dark environment (the auto brightness is set to ON,of course), this occured sinced I updated from iOS 8.2 to 8.3 (all are official version). Also tried to do a clear restore my iphone 6 from itunes on PC but not help.

Hi Apple guys, please help to investigate this and fix ASAP. Thanks

I can confirm the same thing.

If I move from a bright room to dark room or vice versa the screen brightness does not change. I went to a dark area, turned Auto-Brightness off and moved it to the lowest brightness level. Turned Auto-Brightness back on and moved to a brighter area. The slider moved and the screen became brighter. Moved back to the dark area and the brightness once again did not change. I have tested this on both my iPad mini 2 and iPhone 6. Restarting the devices does not resolve the issue.

Hey anypats.Does your ipad mini 2 got this issue or not?You said you tested but dont give result about it.I used to think it's due to hw,but now it seems to be OS related issue.

What I've found is that if you manually chaange the brightness then auto brightness no longer works, I have to go into settings & untick auto brightness & then activate it again to get it working again.

It works again but not stable, after a couple of times reducing brightness as expected, it won't work anymore

Reset, restart,restore do NOT work at all 😟

If you manually adjust the brightness then auto brightness stops working. If the brightness stops working withought manually changing it then it might not change until you're in a darker or brighter room.

As I said I do NOT manually adjust the brightness, just set auto brightness to ON, and sometimes it works, sometimes it does NOT work.

you have to repeat this test more than 2-3 times continuosly so you can observe this issue occurs

Just to clarify, once auto adjust is set by turning off then on are you then turning it off & on again several times or are you moving to a brighter or darker room & noticing the auto brightness isn't working?

just turn off then on 1 time, then moving around dark/bright room several times. At some first times, maybe they work ok, but after trying to repeat the test (moving around...) then it will got stuck when you're in the most dark room (no light at all) but the brightness is still not reduced to 0 (as expected). Got my idea ?

Thanks for the clarification, I have no further suggestions sorry apart from checking that the screen is clean, if it is then you might have a problem with the sensor in the device.

I Have the same exact problem on Ipad mini 3. It simply increases brightness but if i move to a darker room, brightness does not change. Hope this problem can be corrected in a future release, not too far away. Each time now i need to use manual because automatic does not work or is unstable.
