iPhone 12 pro max keeps dimming

Plus one...

Can happen almost immediately. Happens all the time while I’m messaging here. Doesn’t take much “heat” at all to get it going. I’ll be going in to the Apple Store soon. They can keep giving me new phones until they fix it or I get one that works.

I have the same issue. It is at random that the screen will pulsate light to dark. Almost like an obnoxious flicker. Auto brightness is off, no it is not overheating. Happens in a nice air conditioned room where the phone was locked for at least an hour prior. It is happening to both 12 Pro Maxes at my house. I thought that 14.5 would fix it and 14.6 but looks like that was a giant 'NO".

I am wondering if it has to do with the brightness level when you turn off Auto dimming. I wonder if it saves the current level and returns to this level every time the phone locks and then is unlocked. Testing this now. Try it and let me know.

The real issue I have is why does auto-dimming do such a terrible job that we are wanting to shut it off? Why does auto dimming leave the screen unreadable in bright lights and blinding if you are in a dark environment?

I had the same problem with my iPhone 12 Pro outside on a sunny day. I couldn’t see screen to order table service. I asked my wife to let me see her iPhone 11 and it was fine. I went to Apple store round corner from where I was and they agreed it wasn’t working correctly and gave me a new phone. I think The iPhone 12 has a problem.

This dimming issue has been a habitual problem since I had an iPhone 5. Even after turning off the auto dim function, Apple takes the liberty of dimming your display even further when the temp reaches a certain limit. So, if you're at the beach in FL, forget trying to view the display for a photo you are trying to take. The screen virtually turns itself into a mirror and you cannot see what it is that you are trying to get a photo of. I call it the "Tim Cook Cosmetic Mirror Effect". Terrible outdoor display in the southern latitudes. My current iPhone is obsolete and I have been researching my next phone. From what I am seeing here, the iPhone12 is just another pig in lipstick and not a winner - in fact, it really seems no better that some of it's predecessors. So, it looks as if Samsung is getting the nod on this one.

The new iPhone overheats easily and is crap, everyone who uses their phone at full brightness experiences this, even if you have True Tone turned off, and both auto brightness settings turned off

Yea I think it’s pretty clear the dimming issue is bad. Even indoors turning the face of the screen toward and away a brighter light source results in the same issue. There seems to be layers of dimming too. Outside it’s 3 or even 4 levels of dimming until the screen literally disappears. So it’s not just an overheating issue. Maybe we should record our screens dimming and place them together. If you screen record the issue it’s not seen (rather amusing) but recording the screen issue with another phone will catch the problem… maybe then we can all visually compare and contrast (pun intended) our individual dimming issues …

The iPhone 12’s and above have this mechanism that when you’re using “too much power” the iPhone will automatically dim brightness. Even though you’ve followed procedure to prevent this, it will do it regardless. It’s annoying, yes. If you contact support, they would advise you to reset your phone with no backup. This does work but only because you won’t have the need to run anything. It’s not very practical. There’s nothing we can do unfortunately.

Same, ive tried all settings and actually had apple run a diagnostic with my phone they said there was something wrong with the screen… so they replaced it i was like finally!! no more hot phone and the annoying diming!! Yea right… brand new phone keeps doing the same thing!! this one is worse this actually stops working because it says temp is too high!!! Apple do something!!!!!

There is no doubt it is linked to the overheating prevention. The concern is that no other iphone used in similar conditions face the same pb and no android face this issue.

Therefore the phone design or its built is in question.

True-tone - OFF.

Auto Everything - OFF.

What is the problem with your automatic phone 12XPRO going dark all the time by itself. The only explanation that makes sense is that my phone is possessed by ghosts. ABSOLUTE CRAZINESS.

I have the same problem. Regardless of the setting of the auto brightness switch in both Display and Accessibility, or Trutone setting, the phone just goes dim - in my case if I plug in a charger. The only way to get it to brighten is to turn the phone off and on. I pay a monthly fee for AppleCare on the phone an all I got after reaching out was send it to us and we will send you a new one at a turn around of two weeks, or buy a new one ($1000+) and we will refund you once we get your old one, again around two weeks. So not only is the iPhone (mini) a poor product marketed with known flaws, but Apple's extra cost warranty program is about as user friendly as a train ticket to Antarctica. Thanks Apple! Cancelling one AppleCare subscription post haste.

It’s crazy how common this is and people don’t even realize it. People aren’t stupid.. we know about auto Brightness. All brightness settings are off and the screen randomly dims well below screen brightness then randomly shoots to make screen brightness. It’s not a gradual climb and gradual fall like with auto Brightness.

I have have iPhone 12 Pro and it does this ALL the time. I watch a lot of YouTube and anytime I watch it with Bluetooth headphones it dims. And yes I have check and made sure to take off all of these auto settings like attention awareness, True Tone, auto brightness, reduce white point etc. has anyone found a solution to this or take into apple to see what they say?

I am currently in Thailand on business. I purchased the iPhone 12 pro max for the camera and to be able to use it to take photo's for my work. As it has turned out I get my staff to use their Phones to do what i need to do as the iPhone is useless.

1) The ability to take close up photo's that are clear and focused is non existent. (admittingly, there has been some software updates that have improved the camera with close ups since the purchase nearly a year ago)

2) The weather is hot and humid in Thailand when I take the photo's outside in the sun, I can successfully take 2 or 3 photo's and then the screen dims so much that I cannot see to take photos or even select menu's. (I have recently ventured back to cold and wet Melbourne and I was totally unaware of the "auto brightness" in the accessibility under display and text,

I will try this in a couple of weeks when I am back at work, but if it doesn't work it will be finally time to switch from Apple phones. I have been a loyal customer since iPhone 3. If it can't do the job why support it! 3 of my staff members have androids. The Samsung S22 Ultra, has a much better macro ability and also has a 100 x zoom. Try and take a photo of the moon with your iPhone 12 pro Max. I just can't do it its all blurred and the colours are wrong.. In Thailand there is some lovely red moons at night time with the iPhone a photo of this comes out orange and blurred. A macro of a plant leaf or an insect on a plant leaf is impossible. Very upset! The iPhone 8 I had actually took better macro's. The iphone 12 ProMax does take beautiful clear photo's of scenes, etc and it has some wonderful facilities with pano, portrait, etc. Its time for apple to stop stuffing around and add macro to the tabs in the camera!!
