iPhone 12 pro max keeps dimming

I have the iPhone 12 Pro Max and it constantly dims. I made sure the Automatic button was off, it still dims. I went to answer the phone and it had dimmed itself down to an almost completely dark screen. I am constantly having to reset the brightness back to where I can see the screen. Any "bright" ideas?

iPhone 12 Pro Max, iOS 14

Hey guys , I had the same problem. My auto brightness was off and my phone kept dimming. Then I discovered that I had “reduce white point” on , once I cut it off my phone went back to normal. Go to accessibility-display and text and it’ll be right above auto brightness

Can’t believe now many people are having this. It’s exciting I am not alone 😆 shame it’s not easily solved 🤦🏻‍♀️

I did really honestly thought it was just me. Well the phone. I’m not so lucky so I just crack on. 🤷🏻‍♀️

I have had iPhone mini replacement for this issue previously. I’ve sold that since and I now have the purple mini.

This is the same unfortunately.

(All the dim and brightness battery and face attention etc are off. Always have. I’ve tried force restart. I’ve tried reset and set up as new).

I’m just saying this so it doesn’t get re-suggested lol I’ve read the thread. 🤐

I’ve still got a iPhone 11pro. Thinks I may use this if I can’t find my happy ending..

I’ve not felt a phone get this hot for long time.

It’s archaic… shouldn’t happen in this technological era. (I’m sad) always loved apple.

And I’m out of pocket. I’ll be in touch with apple as I pay the apple coverage too. See what happens. 🙄

I normally would be kicking my own *** because I ‘should have got the 12pro’ but I don’t even feel like I would have it.

The mini was what I wanted. I was well excited I love having a small phone, I’m tiny so it’s a nice thing to hold a phone and not nearly drop it.

Very disheartening 😵‍💫 (ah well, I’ve been trying to get use of the emojis while I can) 😬⁉️

I’ve tried capturing the issue with a screen recording but it doesn’t capture brightness changes. The recording just plays back at the current brightness setting. Unless of course it’s starting dimming.. lol. Like you mentioned when it’s acting up adjusting the brightness slide bar doesn’t do anything until you get to around the bottom 1/3 of the bar.

So I had my iPhone replaced around 2 weeks ago because it had the screen dimming fault.. it failed all tests in store so they gave me a new one. Now my replacement phone not only has the same fault… but now my **** cameras don’t work! Like ummmm, what the sh*t apple! No Face ID, all three rear cameras don’t work and nor the front.. I know they’re not broken because when I open the camera app they briefly show an image then instantly freeze, FaceTime says another app is using my cameras and my Face ID works for passwords but not to actually unlock my phone! I’m so disappointed and frustrated with apple and how janky these iPhones are!

I’m still having issues with my screen as well. No matter what settings I play with it does not help!! I’ve turned it on and off and turned off all auto dim settings and still dims whenever it wants?! Why is this an issue? I do not understand it. It has given me so many problems. :-( please fix this issue in an update or something!

Unfortunately, none of the suggestions, including the latest update, has done anything to fix my constant dimming problem which tells me my new 12 Pro Max is defective. This is just a pain because now I’m going to have to figure out how to deal with this problem with Verizon. There’s always something….. thanks everyone for the suggestions though! It’s greatly appreciated!

Having same problem with iphone 12.


I bought this phone 2 weeks ago and it is having these problems.


I also went to the local ishop in El Salvador, they told me it could take around 2 weeks to fix. I would be without a cellphone for all that time. This is a very bad experience for an expensive phone that is not working, they should replace it inmediately
