For who is interested: I tested 20+ phones, and the Oneplus9 had the least complaints. Since 3/4 year all complaints vanished, just like that. I think because of a software update…
Usable Smartphones?
I got a TCL A20S, with Nova Launcher, and Disabling HW Overlays, is useable pain free
TCL A20S? I am not sure this phone exists. There is Samsung Galaxy A20s

why doesn't anyone check for flicker through a microscope? then we could be more objective for the majority about screen safety.
my friend from another forum tested several android phones, iPhone 11 and incell screens for iPhone 12 Pro Max and iPhone 14 Plus
the safest screen among android turned out to be Huawei Mate 20 and I confirm this, in five years of use I have never once encountered problems with this phone.
On iPhone 11 he noticed strong Temporal Dithering, which can cause symptoms. the incell screens for iPhone are more complicated. the most flicker-free screen was the screen from RJ factory for iPhone 12 Pro Max, flicker was either not detected at all, or was very slight and only on certain settings. but after iPhone 12 or iPhone 13 RJ factory changed the technology of display production, the pixel structure changed and the screen began to flicker more. Of all the screens tested for the iPhone 14 Plus, the most flicker-free was the screen from HL factory, but it is of low quality with poor colors and still flickers more than RJ for the iPhone 12 Pro Max. He also tested screens from JK, EK Pro, TC and a few more completely unknown and they all flicker noticeably.
I'm also attaching a video comparing incell screens and iPhone 11 where you can see the flickering.
snksmxnzkz mate 20 doesn't use temporal dithering ?
jordan Through the microscope, flicker is either completely absent or almost imperceptible. so far, this is the most flicker-free phone of all tested phones.

snksmxnzkz Ah. Was hoping to buy iphone 15 pro and RJ screen for it.
As i have RJ for regular 12. Its not usable for me for something like maps navigation, reading or youtube playing but after installed RJ i can use it for camera, sound recording and voice pitch monitoring (which requires me to stare at the screen a lot), but for some reasons staring at the app called Singscope doesnt hurt my eyes opposite to google maps in night mode (immediate pain)
My main phone is iphone 11 which doesnt hurt at all. But cant find another 11 which will be the same pain free for my eyes. Thats why trying to prepare myself to the moment 11 screen will die.

Cons Maybe on other iPhone models the situation with flicker will be different, I have not yet been able to find measurements of incell screen flicker for the 13th and 15th series of iPhones.
I don't exclude that the incell-screen manufacturing technology is different for each iPhone series, or the hardware of the device may affect it.
We have too little data because no one checks their screens and doesn't know about Temporal Dithering.
Besides, it would be worth writing to all factories that produce incell screens and ask them for more data about this situation.
snksmxnzkz …because all theories don't match reality/pain issues.
I am still waiting for an academic proof/relation between temp. dithering and eye discomfort/nausea/headaches.

I wouldn't hold my breath. Ignoring questionable certification such as TUV we've just barely established low frequency PWM with high modulation as harmful and have had product changes as a result.

Sunspark A client of mine provides me the Samsung Zfold6 on Android 14. I don't use it every day, but when i do use it is usually for the whole day. My experience with it is that the internal screen is ok, however the external screen is hurting my eyes. I use the external screen e.g. when i take the tube and i cant use the phone with both hands. It is a bit tiring to open the device all the time and this is the main reason I haven't purchased it for personal use, given also the very high price.
Strangely the smaller fold Samsung is giving me eye strain straight in a few minutes of use. I tried it in a couple of stores.
I need to find another phone because my trusted A70 (still in Android 9) is malfunctioning (screen freezes very often).
Leachim38 It's not a theory, it's evidence based. our eyes hurt because of flicker, I pointed you to a way to test that flicker.
13 days later
Was using an iPhone 16 Pro Max for quite a while tonight helping with the setup, more tomorrow. It already had a cheap glass protector screen slapped on it. Bold font option turned on. Seemed fine.
What about TCL 50 pro?
My galaxy s22 is basically issue free. It's oled so has PWM but my understanding is that it doesn't dither. I think for me dithering is the main issue, so the s22 works for me.
pavelbures Sorry it's the 20s, not A20s

Still my daily driver, with HW Overlays disabled it very tolerable.

There isn't one. Everyone jumps on the "dithering/flickering" explanation cause it sounds like it makes sense. IMHO it has pretty much zero to do with our condition
If someone wants to try older iphones: my wife is using an iPhone SE 2 for a few years now, doesn't have issue with it, and I never had any issue with it either, including today using iOS 18.1.1.
(compared to my iPhone 12 Mini which is a pain to watch for more than a few minutes).
Limitless I'm switching to an iPhone SE 2020 (2nd gen) from my iphone 8. It seems to have an identical display. I tried an 11, but the display was newer, and the OS was updated all the way, so it wasn't good for me. If you can find an older 11 that somehow still has a good battery (or where the battery has been replaced but not the screen) you might have luck but right now the SE 2020 seems to be the best bet. It's the same generation as an 11, so it'll support iOS updates for quite some time.
