Upon seeing here that an iPhone 7 Plus has "0" PWM I ordered a refurbished one from the on-line Apple store. I am very disappointed that I still get migraines from it. I must be making a mistake some where -- any thoughts?

And the question is - which top rated smartphone to buy if you are eye sensitive? My favorite is down (Samsung Note 9)..... any suggestion? (without iphone)

"Smaller values are better" - whaat? Is 50 Hz flickering is better than 5000 Hz?

Just checked with my camera and NOKIA Lumia 930 pulsates at 120Hz.  Painful! Mitigated by manually switching display brightness to high.

 Since we can always return new purchased laptop within a few days, I would check PWM on my laptop first thing and then return it, if it had bad PWM. What would be the best way to do it? Is there any software, or do I have to buy special equipment...? thnx.
PS: I do not think a metod of moving a line on monitor is gonna do it, since PWM is very high these days, or am I wrong?

So an "easy" way to do it is using e.g. the highspeed camera mode on most modern smartphones. With 120fps e.g. you should be able to see flickering up to relative high frequencies. Low frequencies can even be seen in any camera monitor or on the smartphone screen when taking a video. The high PWM modes in the kHz range however can only be captured with high end probes like we use.

Regarding the "smaller values are better", that comment is meant for benchmarks marked with a * as this list can be used for more than just showing PWM values (where higher is of course "better", but 0 is best).

Instead of 0, you should have used infinity symbol "∞" so that it is sorted together with higher numbers - not lower ones like now. Logical.

I can definitely say that the following 2 phones cause eye strain:

- Huawei Mate 20 X (OLED)
- Motorola Moto G7 (LCD)

Both caused vision problems, head discomfort, and a terrible feeling after a short amount of use (20 minutes or less, but I can tell in less than about 60 seconds of use).

Now I'm stuck selling the Huawei, still new in plastic. I returned the Moto G7 immediately. Motorola was really good about the return process (thank goodness!).

I'm going to check out Asus ZenFone 5Z & the new ZenFone 6. At this point it's getting ridiculously hard to find a nice big phone with good camera what won't cause suffering.

I should add that I also had issues with recent HP 24" monitors I bought with LED lighting and had to go back to older standard monitors which are ok for my eyes.

Thanks for this great list!

Fellow PWM and flicker sensitive users who get headaches and eyestrain please let us know what new phones work for you.

It is getting harder to find ones that do, even some listed as 0 PWM seem to cause problems so please add ones that work for you in the comments list.

Thanks
