This is getting RIDICULOUS!! The only tolerable iphone is the 11 that i was using it since day one. Last year i tested an SE2022 and my eyes burnt like hell and got nausea. 2 weeks ago i found a sealed iphone 11 and purchased it instantly.... i sold my old 11 and started using the fresh 11..... it gives me dry eyes and mild dizziness.... SO WTF is going on? Are we sure our issues are PWM related....? I installed a dark screen protector and the fresh 11 is more manageable but not pain free still.....like my older iphone 11.........

There is plenty of evidence that the iPhone 11 dithers heavily, plus there are several other factors other than pwm, please use the search function

I am thinking to purchase an Oled iPhone and replace the screen with XO7 soft oled from mobile sentrix….. it is LTPS and some say that it uses DC dimming….

@"DJTaurus"#p43965 are they of the same IOS or not?

@"DJTaurus"#p43965 The panel supplier lottery definitely exists for iPhone 11. For example, I've needed to look at my dad's iPhone 11 every now and then and it's OK, still not really something I'd say is "great", but I'm able to look at it, use it, and read text on his phone when I've needed to without any serious issues. The light source coming from the backlight seems OK-ish. I feel like some people on the forum (such as those who are OK with some IPS panels) would find the panel on my dad's 11 fine for them. On the other hand, one of my friend's iPhone 11 has a totally different panel, which is very reminiscent of the terrible panel I experienced once on an iPhone SE 2020 -- this friend's 11 probably has a panel made by the same manufacturer. The glass on this friend's 11 has so much glare and reflects light super weirdly (I get immediately dizzy looking into the glass even when their phone is off, which doesn't happen at all with my dad's 11). In addition, the friend's 11 screen is very hard to read for me, everything looks like it's floating above the screen or glowing. And, even looking at something on my friend's phone for only two minutes causes me some double vision and immediate disorientation, and I actually have to take a bit of time to re-collect myself after looking at their phone. The backlight also appears very harsh. Meanwhile, my dad's iPhone 11 is not at all like this -- his phone is still decent enough for me to tolerate looking at and reading for a similar time, and I don't experience any immediate dizziness with my dad's phone. I've seen this "much worse" panel my friend has, on a good amount of other 11s as well, so I know that both the decent panel on my dad's phone, and the other terrible one, are both stock / genuine panels that can ship with the iPhone 11 (not replacements) I've seen both my dad's 11 and this friend's 11 running the same, latest iOS 18 version. Both devices do NOT have any screen protector. TLDR: The panel supplier lottery is real, and can entirely make or break a phone's usability for me ---

It seems sharp panel for iPhone 11 is the best. Mine is from Toshiba

@"DJTaurus"#p43987 You mean your old iPhone 11 is using Sharp panel and the new iPhone 11 is using Toshiba panel? And they are of the same IOS? Then the reason could be due to different screen panels.

@"DisplaysShouldNotBeTVs"#p43976 So the differences do not lie in the model, the IOS, the screen protector. Could the difference be caused by different screen manufacturers? I mean, iPhone 11's screens are made by three different manufacturers, namely Sharp, Toshiba and LG. It will be great if you can check the screen manufacturers of the iPhone 11 you have seen.

@"ITwebs"#p43991 Unfortunately i sold my old and never learned what panel it had. New one is from toshiba.

I finally made 11 to work…. While double invert didn’t make any difference to the oleds i tried it worked with 11…. now it’s almost tolerable. But i ll continue searching for one with a sharp panel.

Differences between iPhone 11 units

ITwebs after you erase the phone. You restore it from iCloud or you set it up fresh and downloading all apps one by one ?

DJTaurus

Yes, immediately feel more comfortable, at least it was not causing instant strain. I just used the phone to restore. I go to "General" , then press "Transfer or Reset iPhone" and "Erase All Content and Settings". That is all. After that I just used "iCloud" to restore some old data and installed some apps from app stores.

DJTaurus

I just purchased an 11 with sharp panel. My eyes are thanking me again. Such an easier and smooth experience. Zero irritation. Let’s see now what iPhone 17 line will bring to the table. I don’t want to go to android…. tried 24 ultra and I hated the OS.

Good to hear that you find a usable phone. Is it a new phone? what IOS is installed in it?

DJTaurus

ITwebs It was manufactured 2024. Latest io 18.5.

ITwebs

DJTaurus

That means if the screen panel is good enough, then the phone will be reasonably comfortable even when IOS 18 is installed.

That may solve the mystery why some people find iPhone 11 with IOS 18 comfortable to use while others find it unusable.

How about the degree of comfort? Do you find this new iPhone 11 with IOS 18 installed more, less or equally comfortable when compared to the old iPhone 11 that worked for you.

DJTaurus

ITwebs better even than my old 11 which sometimes gave me heavy eyes. It’s lighter feeling too.

ITwebs

DJTaurus

That is good. But then it also implies even with the screens from the same manufacture, the quality can differ?? Like, Sharp has screens of different quality.
