iPhone SE 2022

ICEWHYTE

Hi all,

I've been struggling with migraines for 6+ months now. I've tried all sorts and seen many professionals but was getting no where. I read about PWM and it made sense as I literally got an iPhone 15pro the day before my first migrain (I know it sounds stupid that I never linked the two but I had no idea people were sensitive to such things). Once I read about it, I put the new phone in the drawer and started using an iPhone se 2022, the migrains and tensions went away for around a week (it was amazing) but then they came back. I can't say for sure but I think my SE did an update to 17.4 around the time it started again. My question is, does anyone know what has happened to the SE that has caused this? Anyone done a test with a light meter such as the opple one? WOuld be amazing to see a before and after the ios 17 update to see what if anything has changed.

ICEWHYTE if you can use iphone se with brigthness not 100 % without eystrain and migraine than i think pwm is not your issue but temporal dithering is, same with me i can use my phone without eyestrain and migranie before update os,after update os i got eyestrain and migraine its not coicidence right

I'm similar to you. Was never able to use the OLED iPhones. I remember the day I got my iPhone X when it came out I almost called 911 because I got symptoms out of nowhere and didn't realize it was due to the phone.

I was able to use old Apple LCD devices as well and could look at them for hours completely comfortably. But now if I update devices beyond certain iOS versions they become completely unusable. I summarized the versions in a post a few months ago.

As far as I know there hasn't been an iOS 17 version I can use but I haven't tested all of them on LCD screens. I currently use an iPhone SE 2022 on iOS 16.1.1. I can look at this for hours with no issues.

I tried contacting Apple about this to see if they knew what changed and/or if there was a setting that could get me back to the "old" way of however graphics were rendered. I didn't really get an answer but they did say they would get the information to the appropriate internal teams. I feel like there potentially could be some type of accessibility setting they could add if they hear about this issue from enough people.

I'm really at a loss as to what the actual cause of this is. I can put a "good" and "bad" version of a certain model of iPhone/iPad right next to each other and visually they look exactly alike. But one will make me sick and the other won't.

If you look at threads here on Ledstrain it seems something similar has happened between versions of the Mac OS as well. Also recently on Windows. So not sure if there is some type of graphics rendering that everyone has started using.

Hi, similarly to you, I cannot use any oled based iPhones. I’m currently using XR with ios 16. I recently got iPhone SE 2022 and updated it to latest iOS. It made the phone completely not usable for me despite being an lcd screen. It would appear that iOS 17 introduced deeper colour palette that is resulting in dithering to generate billions of colours that the screen is not capable of displaying. I’m back on iPhone XR and have no issues at all - I’m not planning to update it to iOS 17 in case it ruins this phone for me. Hope this helps.

GZunit have you try downgrade ios and make eyestrain migraine gone ?

ICEWHYTE

GZunit Have you tried the SE on grey mode? I would assume this would rule out dithering issues (could be wrong) but it also gives me a migraine after a few minutes.

hansennnnn Am I right in thinking that OLED screens don't get temporal dithering? My iphone 15pro also gave me migraines so assumed it was also PWM sensitivity I have. Moving then to SE, it must also be TD, however I have been using it on greyscale mode (100%) so no colour, also giving me migraines. Very confused.

It is unfortunately very hard if not impossible to downgrade your iPhone to previous operating system. I looked into it and without apple’s support you won’t be able to do it and maintain full functioning of your iPhone. Maybe someone else on this forum knows more on this subject.

ICEWHYTE if you can use your old phone brightness not 100 than you are not pwm sensitif.we can make sure that it is a software problem either is dithering or something else because i look up on telegram ledstrain grup there is someone tha already root their phone and setting dithering off but still got eyestrain,have you try downgrade your iphone ?there many way in google or you can go to service center.

in my case i use android before update android 14 i can use no eyestrain no problem at all but after update 14 i got eyestrain and migraine with the same phone and than i go to service center to downgrade it but after downgrade to 13 i still got eyestrain and migraine,so right now my solution is buy a new one with same excatly type and make sure not to update it,i buy online maybe today or tommorow i get the new phone,and i already make sure all of batch of this phone all of them use androi 13 from factory

someone in here say " The problem is, for example, your previous 13 android not modify this data, when 14 - does. Thats why after rollback, you can still have eye-strain ( 13 android exist "

ocean10 It's very confusing, I can't seem to put my finger on it either. If it was simply due to change in the colour rendering, you would expect greyscale mode would resolve it but for me it's just the same.

Also, noticed it on one of my Windows 11 laptops. It does help having that on night light though for some reason.

Yeah greyscale doesn't seem to resolve it for me either.

None of the modes worked for me with the iPhone SE 2022 on iOS 17. In a way it was worse than any oled iPhone as it made me feel sick Alamo immediately. My friend who develops apps for iOS, let me know that iOS 17 introduced much broader colour spectrum that was not used with previous iOS versions. Oled can dither too as far as I understand.
