iPhone 8 Plus Screen Auto Dimming

Same thing, iPhone 8. It’s been nearly a year and no fix, hundreds of us have this issue, I’d recommend keeping your phone usage down as much as you can I guess? The less you use it the less often it’ll heat up, and if it constantly heats up like that than the issue will get worse (at least that’s how it is for me) so the more often it’ll dim, and the last thing you’d want is to be trying to squint at a website or something trying to figure out whether that letter is a 5 or an S. Maybe someone at apple will see this and fix it, hopefully it’ll be fixed with the new update coming soon? good luck everyone!!

We wook out to our local service provider & he found a hidden setting. that fixed it for my husband but he had to dig around to find it in settings. There is the true tone stuff then under another feature there are two more spots. I am trying to get the information so if I find it I will post it.

This is also occurring on my phone and it is incredibly annoying and frustrating. When I set a setting to one thing, I expect it to stay set. Is there a fix in the works Apple? Is there an update or something that can done in settings? I am older and my eye sight isn't the greatest. I need that bright light on folks!!

Go to Settings/General/Accessiblity - Display Accommodations and turn off Auto Brightness. Then go to Zoom (in the same place) and turn it off.

If the brightness continues to dim on its own that means that they phone is approaching the upper limit of its operating temperature range and it is dimming the screen to reduce the heat load. The alternative would be for the phone to abruptly shut off when it reached the temperature limit.

I purchased the 8 plus new last month due to the new models not having fingerprint sign in for bank accounts, etc. I’m experiencing the same brightness issues as others. However mine is not from being on any particular app when it occurs. If I charge it, the next morning the screen brightness has been changed to a lower setting.

If I close the apps and put it down without any app running and not charging it lowers. My wife and I both have the same phone. She has no problems with hers but mine is causing lots of problems.

We’ve used apple since the iPhone 5. If none of the fixes suggested in this thread fixes the problem then I’ll most likely move back to android.

I don’t understand why apple insists on changing things that their customers like and changing them and then they don’t fix problems when they are told that it causing problems.

Facial recognition is great to open a phone but most banks and credit card companies don’t offer facial recognition as a means to open your account to make payments, etc.

I’ve had the same issue with dimming. It is soo dim I can barely see what is on screen. I noticed it always happens during the daytime and when it is sunny out. I also noticed the phone is usually hot and it is below 50% battery life.

I’ve had this issue on the X. So I bought the Xs hoping it would go away. I have all auto brightness off. Reduce white point off. And it’s still happening. Any ideas?

Hi guys, Im also experiencing the same thing, APPLE told me to restore my phone using DFU mode. I also noticed that my screen is yellowish compared to other iphones but they said that it's normal.

Hi Matt, is the dimming issue still occurs?

ive downgraded to iphone 7plus and its still happening.. waiting for apple to see this thread.. lol

Same with mine, purchased one month ago. I read answers and will try white point reduction

Hi Mat, Any updates from apple on your issue?

I have the same issue. I found that maybe its related to temperature. My phone was hot when I’ve experinced this, but I dont know the reason I just scolled facebook nothing else. :(
