Anyone noticed eyestrain when using the iphone 8 after updating to ios 14.7 or 14.7.1? Yes i have it :-0 seems that Apple messed with the display drivers again. and the worse part is that i cannot downgrade to 14.6 anymore...
I haven’t noticed any change in eye strain. I also suffer from migraine induced vertigo and notice I have a lot more episodes when using an oled screen up close for extended periods of time. With the se2, I really haven’t had any major vertigo spells.
How do you check if your DEVICES are non US market and models that are not covered or reviews by RTINGS?
There's got to be a way/ methods?

Rtings for example, check Image Flicker test:
I haven’t seen anyone else mention this issue on 14.7, are you still having trouble with the update? I’m holding off for now.
Yes me neather, but yes i still have the issue of getting immediate headache when using my iphone 8. I do use another phone at this moment
can't even believe it myself
No. the problem stems from the backlight dimming technology, it has nothing to do with the colors displayed on the screen.
My iPhone 8 has always bugged my eyes after some use regardless of the OS. Not immediate headaches or anything but I definitely get more eyestrain using it than my 6 Plus. I can use my 6 Plus all day long (for years) and never any eyestrain - which is why I still use it every day to this day. The iPhone 8 almost never gets used. Regardless of what Apple says, the regular sized old LCD iPhones with 720P screens are blurrier than the old 1080P plus phones.
Their OLED screens blow.
Lets hope the 13 / 13pro brings back the joy of being able to use the iPhone
that is not probable as oled = pwm at low freq... only chance for future right now seems to be miniled, ipad pro uses pwm but with much hugher freq, so hopefully it is almost impossible to harm anyone, but oled, right now, is unusable if you are a bit sensitive to pwm
The Mini led display on the ipad pro 12.9 2021 still bothered my eyes sadly. No headache but my eyes still felt bothered and fatigued. So I'm still relying on Apple implementing much higher PWM with their oled displays.that is not probable as oled = pwm at low freq... only chance for future right now seems to be miniled, ipad pro uses pwm but with much hugher freq, so hopefully it is almost impossible to harm anyone, but oled, right now, is unusable if you are a bit sensitive to pwm
2021 Apple 12.9-inch M1 iPad Pro with mini LED display shows poor display characteristics including reduced PWM and response times
We tested the PWM and display response times in our 2021 12.9-inch iPad Pro with M1 and found that there are some downsides to Apple's transition to mini LED tech this year. The 2021 12.9-inch iPad Pro not only shows lower PWM compared to the 2020 model but also has noticeably higher response...
Different technologies implemented in different ways.If you are bothered by ioad pro miniled, ni chance you will get oled iphone that wont bother you, i mean ioad pro uses pwm with freq aroung 17k, iohones are right now on 240? so please apple, give us non pwm ips iphine again
Will just have to keep buying products and testing them to see if I can live with them or not - hoping for a change soon. ?♂️

i do think it has something to do with the dithering and that it effects us more than we think or know. When they have a true 10bit display this might be solved.
Apple could do way more like Honor shows. The new Magic 3 Smartphones has a PWM Frequenzy of around 2000 with low light and should not make such a problem like the current oled smarphones from apple. I hope so much that things getting improved this year.
Just looked at this phone, this is insane, the camera's and the screen. TUV eye safe certified
Really want to try this phone
IT seems other brands take pwm flickering serious and set the pwm rate over 1000 hz to avoid flickering and healt proplems.
Latest example Honor Magic 3 with 1920Hz high-frequency PWM.
Compared to 240 hz in the iPhone 12 series....?

Does it give apple some kind Power Savings? Would chip designers / hardware folks know if and how this plays out?
Yep i guess its all about power saving and using cheap hardware to save cost, tweaked to look good with software adjustments like pwm or dithering to show more colors.
