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
So.. I had my apple appointment yesterday, I made sure to video the screen dimming too before I went in, I showed them the videos and explained the issue I was having, to which they admitted was very strange, they said it’s most like software based to which I agreed, but i said, what are you going to do about it, to which they responded, there’s nothing we can do, other than try a screen replacement, so I said go ahead. Now, to do the screen replacement they have to plug the device into a diagnostic machine which will look for a fault and then allow them to do a repair, so they did this, and to both mine and the employees surprised, there were 5 faults with the device! It failed the screen test, the face I.D test, ambient lighting test and two other which I forget, but this meant that they couldn’t do a screen replacement as there were many more issues, so their solution… they straight up replaced my device there and then in the shop! I was gob smacked at this point as usual you’d hear horror stories of how they will blame you and send you away! So far it’s been 24hrs, no screen dim! I’ve even done the things I did before to make it happen, and nothing! So for now, I am happy, I hope this device continues to perform correctly and if I do experience any issues I will be sure to note them here!
my advise, video your issue on another device and head to your nearest apple store!

Helps to include the info! “There is 1 more Accessibility feature that can cause the iPhone 12 dimmed screen issue. It’s found in Settings -> Accessibility -> Zoom. Tap Zoom Filter & if it’s set to ‘Low Light’, switch to ‘None’! When enabled this will cause your iPhone’s screen to display w/low brightness when using zoom mode
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

Well great. I’m still making payments on my phone and just this week I noticed it seemed to be going darker while using it. I thought I was seeing things. Then I caught it first hand and realized what was happening. It seemed as if it was going in the stages of “sleep mode” except not as dark. Then it would brighten back up suddenly. Ughhhh. This angers me. Pay all that money and it messes up before you’ve had it a year.
Go to Settings/Accessibility/Face ID & Attention and turn off Attention Aware Features. When it is on the screen will dim if you are not looking directly at it.
Ok
yesterday I wrote about the zoom feature and keeping the brightness on at 90% and I thought I'd cracked it !
no it started again .. what had I changed over Christmas that might be causing it to over heat .. my cover .. to one with a much thicker plastic bumper ... I e put my old cover on today and it has not dimmed once
SOLVED - iPhone 12 Max Pro Dimming.
A non-apple case causes it to overheat!
My iPhone was fine for two years and I switched from the Apple purchased case that I bought at the Apple Store for a non-Apple case to enjoy a new color. Didn’t think about it but started having problems with my phone dimming.
It was constant if I was googling or reading texts etc it would toggle up and toggle down from bright to dim so I could barely read it. It was ridiculous.
Tried everything the Internet suggested. Turning it off helped but that was only because it was cooling it off. It didn’t solve it. Changing any and all settings did absolutely nothing.
Read a post that mentioned they thought it was an overheating issue. Remembered that I had just purchased a new case before this started. Put back on my Apple purchased case. Voila. No issue for a whole month. SOLVED
There is a auto brightness in the accessibility under display and text you need to turn off as well. This fixed my issue.
This works-posted by a different user.

Go to Settings/Accessibility/Face ID & Attention and turn off Attention Aware Features.
Then go to Settings/Face ID & Passcode and also turn off Attention Aware Features.
Midnighttsx solved my problem with the dimming issue. The auto brightness in the accessibility/display was indeed turned on. I turned it off and the screen is no longer automatically dimming.
I called Apple tech support. Eventually got a supervisor. He said with iphone12 there’s new stuff in there that causes the phone to possibly overheat. It auto adjusts brightness regardless of the setting you choose to help with overheating. When it heats up by being in your pocket, exposure to sun, or just general use, you’ll notice it happen. This makes perfect sense for all of us who’ve tried everything. Sucks because I have to have my phone at near full brightness to see anything without straining. Wish I would’ve kept my iPhone 8 longer and skipped the 12 in hopes that the next model would have this little nightmare figured out. Totally disappointed. I hope they come up with an iOS fix but it sounds like it’s a hardware design issue. Sorry to break the news to you.
When you get all your settings in order like others have mentioned, a force restart of your phone will preserve the settings for you. I tried everything and this simple trick is what worked. Apple, please start sharing this trick on tech support! //// Force restart: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button.
Yo, I THOUGHT I disabled the auto brightness option, but you have to click it on and off again, in BOTH accessibility and display. MUCH brighter now, I’d say I’m getting the full 800 nits now. Definitely brighter than the 11
Same problem
I went into accessibility into zoom and the maximum zoom amount slide was a quarter over .. I moved it back to zero
and then took the phones brightness down from full to about 90% and it has stayed there since . This is defo not a heat issue
iPhone 12 pro max keeps dimming
