Samsung Z Fold 3 - causes horrible eye strain due to low Pulse-Width Modulation (PWM).
I know several new Z Fold 3 users including myself started experiencing eye strain after using the device. None of us ever experienced this before from other devices we had in the past. I had all the Galaxy Note series all the way to Note 10 plus.
After going thru and testing, the eye strain was determined and caused by the Z Fold 3. This was confirmed by myself and several other users.
Typically PWM kicks in around 20-30% of low brightness and does not kick in at all at 100% brightness, However the Z Fold 3 flickers or still employs PWM even at this level.
Question to you Samsung engineers or product managers; are you aware of this? are you going to fix this via firmware update? what can I do to remediate this? are you planning on improving this implementation in the future Z fold display?
I love the Z fold 3! it is the best device around, but this is a show stopper, please help!
I saw that this issue already has been reported, but Samsung did not reply nor am I allowed to answer the previously opened threads (may got closed by Samsung) – so I open a new one!
I used Samsung Galaxy and Note devices for years now and never had any problems. My last phone was the Samsung Note 10 +, well "was" is not correct, actually I switchted back to it.
I own a Fold 3 now for 2 days and whenever I use the inner screen (no matter what settings) I get eye pain within 15 to 30 minutes and also headache. Both getting worse they longer I use the phone. (My eyes are absolutly healthy and I see very sharp, so no, is not on my side).
I googled it and saw many posts (like on Redit) about other people having the same issues. Most people refer to poor PWM as cause of this issue.
However: I would like to know if there is a fix for that to reduce this problem or will Samsung deliver some update/fix in the future?
Otherwise I have to return that phone if possible because right now is unuseable for me!
And that at the given price point is not acceptable, sorry Samsung!

I have the same problem with my S20. My eyelids burn, my eyes feel strain and my vision seems affected, and I get headaches. Its to the point that I have to limit my time looking at it.
