DisplaysShouldNotBeTVs caoyirui are you on ios 15.8? i have ios 15.7.1 on my iphone 7 and it has no strain or only very little, it is very usable
ocean10 caoyirui Don’t update to 15.8 if you haven’t already. My iPhone 7 was one of the last phones I could use and I carelessly updated to 15.8. Now it gives me symptoms like more modern phones.
caoyirui DisplaysShouldNotBeTVs The iOS on the iphone 8plus is 16 and on the iphone 7plus is 15.7. iOS version aside, for iphone 8plus, I believe the screen maker and manufacture year of the screen determine whether the screen can cause eye strain.
DisplaysShouldNotBeTVs ocean10 yeah that's what i was implying as well, 15.7 is fine but 15.8 is known to really mess things up
asus389 My 6S with 15.8.2 is OK. But some of the 15.x updates were not OK. Its so strange how a minor update can change something like this (and possibly change it back).
