iPhone screen dims randomly

I have the same problem... Just purchased it 7 days ago

I haven't had this problem on my iPhone X, but it sounds like an anti-screen burning in feature since the iPhone X uses Samsung's OLED screens. So it would make sense, but I'm not 100% sure.

I might try getting it replaced. This is annoying.

It must be the heat thing because it only happens to me when using my phone in the sun

I received a call back. Engineers want me to record my screen when I’m using Waze and if it happens I need to send the video in. Of course today I used Waze and had no issues.

Once it happens and I send the recording to Apple I’ll update.

The weird thing is today it was very cloudy/overcast and I had no issues. It seems to only occur when it is sunny/bright out. Phone was still warm to the touch and it felt the same when the screen dimmed.

I have the same issue… I just got a brand new iPhone 10 and it is doing the same thing as my old phone. I’ve been on the phone with Apple tech-support for three days… This is so frustrating! I cannot use this phone outside… I cannot see the screen in the sunlight because it dims.

I have the dimming problem on the iPhone X. The screen is never very bright, but when it dims it is completely unusable in daylight. CVS drugstore has an app that displays a barcode on your phone that the pharmacy scans when you pick up prescriptions. Whether or not the phone is dimmed they always have trouble scanning mine.

I use this app as well. My iPhone X has no brightness / dimming issues, but the clerk also has trouble scanning the barcode. I believe their scanner requires a very precise angle and somewhat precise distance for the barcode to be presented and recognized.

I’m having the same issues as well, with the screen dimming for anywhere between 2 and 30 minutes at a time. Mostly I notice it on brighter days when I’m using Waze as well, phone plugged into charger, but where phone is in my car is low, under stereo, and rarely in direct sunlight at all. Screen dims and makes it stupidly difficult to read on very bright days, and when driving can’t always reboot phone to fix the issue. All screen settings are set to the absolute basic, even turned True Tone off as a test the most recent trip I took. Seems like my screen dims to about 50%, and when I move brightness slider down from 100%, it doesn’t change til I’m halfway down, then will get dimmer from there, but brightness locks at around 50-60% and doesn’t go up despite setting at 100%

When it happens to you have you left the phone running and has the screen returned back to normal brightness? It happened last week so I left Waze running and after a few minutes the screen slowly returned to normal.

Still have not heard back from Apple. They have my videos/screen recordings so hopefully I will hear back soon with a fix.

In my case this issue of the screen dimming on its own is irregardless of Waze which I hardly ever use. In my case the screen dimming in its own happens seemingly haphazardly and in any app. I wonder sometimes if it has to do with the number of apps open and amount of power the apps are using combined or if it has to do with how much battery is left and the phone is trying to conserve. Whatever the case it’s very frustrating especially when I’m trying to read or use my phone outside and can barely see the words on the screen.

This is my third NEW iPhone X. They all dim outside or indoors. It dims when plugged in and even when not. Bottom line is I was planning using this phone to operate a new drone and that will now be impossible!! Apple must know there’s an issue but doesn’t seem to Acknowledge or admit they have a problem.

Have anyone got this issue solved? Same thing happening to my X. Just got it 4 days ago 😟 I've noticed it's somehow related to the phone temperature in order to prevent overheating or something but guys cmon we spent +$1000 ($1300 in Russia for 64gb) and we expect to get the best possible experience... So, what we gota do? Restore? Set as a new phone? Bring it to service center ? Any thoughts ?

I have the same issue(iPhone X) although where others say their screen slowly returns my phone doesn’t. It’s more like a switch (on or off), I’ll be using my phone on a bright sunny day and then all of a sudden the screen goes dull in a instance. Randomly it will then brighten back up again in a instance. I have auto brightness and True Tone off aswell as reduce white point. Very frustrating especially while playing PUBG.

I see your point but what’s the purpose to use the phone as GPS when you can’t even see the screen?

I get that they don’t want burn in or want to protect the screen but sometimes mine will dim within 3 minutes of using it. There’s no way it’s getting that hot in that short amount of time.
