Yes, I see this exact behaviour. Like a split-second drop in brightness around the 18% mark. Also happens (but to a far lesser degree) around the 45% mark.
Got a tip for us?

So I got mine replaced at the Apple Store and the new one appears to be doing the exact same thing. Going to do some more tests tonight, but sadly this might be a wider problem than just a few bad phones out there. I'm hoping maybe I just got unlucky twice in a row, or that this is a software issue. In other news, a friend managed to already scuff up the stainless steel and the phone is less than 24 hours old...
I saw a similar thread and someone had checked in the Apple Store, going through 9 XS/XS Max models in total and they all exhibited this behaviour. Turning off Night Shift and True Tone temporarily seems to fix the issue, so it looks like a software quirk.
I think the posters have spotted two separate issues:
- An auto brightness 'flicker' lasting 2-3 seconds, which you describe, which does not sound normal and resolved on replacing the handset.
- A widespread reproducible split second subtle 'drop' in brightness, which can appear as a single flicker and can be reproduced around the 20% brightness mark by very slowly moving the brightness slider down from 30% to 0% with Night Shift or True Tone enabled.
I agree, your issue looks to have described something more serious and I'm pleased swapping the handset resolved it.
Sounds about right - I experienced the first issue you described. It indeed did last 2-3 seconds and looked like the screen was interlacing so to speak.
Just to clarify, what I was encountering was constant (not just 2-3 seconds) and does not stop with turning off True Tone or auto brightness.
Yah annoying. I asked someone on new beta to test and they said it not fixed yet. Doh! So annoying.
This image drives my XS crazy. Sets of full-screen slight flicker.. sometimes really bad and sometimes light.. but happens quite a bit.
[doublepost=1540991374][/doublepost]I am on 12.1. It does seem associated with the screen trying to ‘adjust’ something. I will try without auto-brightness on.

My issue is the first one.
I too have the issue where as the brightness changes past 18%, there is an abrupt increase/decrease in brightness that manifests as a flicker. It can be reproduced by sliding the brightness slider up/down past the 18% mark slowly.
I have had two XS Max devices with this issue. iOS 12.1.1 beta 1 does not fix it.

I think this issue is pretty widespread based on other people's XS Max devices I've looked at. I think that most people don't realize the flicker is caused by the brightness auto-adjusted.

It looks like this issue only happens with TrueTone enabled which is interesting.
Had a follow-up with the Genius Bar and this is confirmed as a known issue with the XS models. According to the genius their instruction is to not replace the phones, as the engineers believe this is a software issue. The temporary fix is to go to Accessibility and use the reduce white point setting set to 60%.
I’m still not 100% convinced this isn’t a hardware issue and they are just trying to find a way to mask it a bit better with software for those models that are experiencing it. But that’s what I’ve been told.

Hello,
I just received my XS. After 10’ using it, I agarres to del a light headache so I decided to do some tests:
Firstly, I disabled auto-brightness. Later, if I put Safari in about:blank page and reduce the brightness to 0%, I can’t directly see the flcikering, but if I look it using the iPhone XR camera then it’s pretty obvious.
I have to raise brightness to more than 50% or >30% + Enable reduce white point at 95%.
Same effect having TrueTone ON or OFF.
If I look the XR screen with the XS camera, no flickering in any case.
I see this hardly being solved by software... I believe this happens to all devices, because is how the OLED panel of iPhone X, XS and XS Max works. I think most people saying that their device is flicker free is because they have not tested it well, being necessary another camera to look at it...
Thoughts?

iOS 12.1.1 which I just installed still doesn't fix this issue where as the brightness slider passes 20% (either increasing or decreasing birghtness) the brightness changes abruptly. Some describe it as a single flicker. I believe they cannot fix it at this point. I am very surprised more people haven't complained. Its most obvious with both TrueTone and Night Shift on.
It seems that todays ios 12.1.2 beta takes a big step in the rigtig direction - the flicker is almost gone on my XS.
I do not know what it takes to chance the PWM - but I do not see the same flicker since I updated 12 hours ago. Its like apple changes the way auto brightness works/changes brightness - it feels more smooth in a strange way. But thats just my opinion.
I also had difficulty believing this but I just updated and it’s not noticeable at all with iOS 12.1.2 beta 1.
