lubo I plan to at some point. I think there is 14 phones with the DC dimming option now. I think it was the black shark 2 that even when using the DC Dimming option didn't perform as well as the one plus 7. When I do buy one I want to get at least 90hz refresh rate though.
Usable Smartphones?

AGI I assume there is PWM.
Yes it has very low 240Hz PWM so that's one data point for you that PWM isn't your problem or primary proble. For future reference you can look up devices here if they have tested them. Click the "Show Restrictions" link under the intro paragraph to choose search parameters.
The test equipment goes up quite high but just because the result says "0" doesn't mean there isn't some insane frequency PWM above the equipments threshold, but it's a good way to see if there is LOW frequency PWM.

AGI I use the app "Brightness Manager" by Igor Tseglevskiy. It is pretty perfect for this purpose but has been pulled from the Play Store a while ago (has been there for years). I don't know why he deleted all his apps but it's still available as an .apk file at other sites. @degen downloaded it from a specific site somewhere higher up in this thread and we compared the checksums to make sure it's the original file. I can recommend this app in general for everyone who needs to find a safe non-PWM brightness range. You can view the display through a camera or better oscilloscope, fine-tune the brightness in the 256 levels Android uses behind the scenes and see when the PWM turns off. The set brightness level usually will be remembered after a reboot if auto brightness is off.
This is how I determined this exact value. If you ever use Paranoid Android, the value is a little lower, 65/255.

Thnaks a lot for feedback. Have you tried to deactivate 90Hz mode and activate DC Dimming, makes it any better? It seems that arroung 50% brightness there is no PWM.

So in the next week or so I'm moving the entire family to AT&T (they are having a stellar buy-one-get-one promo on Samsung phones now), which allows me to use GSM phones finally. Planning to hunt around for a OnePlus3. Do we have any idea whether I need to do OnePlus3 or if OnePlus3T is going to be the same? Has anyone used both?

I had the same question. Looks like no one here has tried the 3T...

AGI If you are so inclined post here and ask https://forum.xda-developers.com/ (https://forum.xda-developers.com/oneplus-3t) but be prepared for the usual arrogance, topical diversions, and a really annoying forum design.

What worries me about that (aside from iPhones costing too much) is that its the only LCD panel device they make. Everything else is OLED and it wouldn't be surprising if all will be OLED soon. So if you get stuck in iOS and their OLED devices hurt, then you then have upgrade path. Hoping the Librem 5 isn't crap and whatever solution we may find can be useful there since its going to be running linux and not some proprietary mobile OS.
hpst that its the only LCD panel device they make.
Based on 20 minute testing, I found the XS smoother than the XR though. The XS was the first AMOLED I could look at without having consequences for 2-3 days.
The OnePlus 3 too is decent. I have been using it at night for 1-2 hours for the past 3-4 days, and I seem to be able to handle it with some CVD symptoms. Nothing like the disturbs I got from an S10 or a 6s.
I am confused. Does not it mount a Samsung display? Why can't I tolerate the S10 for a second then?
Also, within a few days I used three different OxygenOS versions, the first two based on Oreo (September 2017 and November 2018), and the last one being the up-to-date version based on Pie. I hate talking of feeling, would like to quantify, but all I can say is that the eyestrain feels stronger the more recent the OS version. I am trying to see if I can adjust to Pie. I am not super-happy, but the morning after I wake up only with a feeling of sand in the eyes and dryness, but no more than that. If I do not use the phone, the symptoms fade quite quickly. Hence the OS seems to play a big role. I had never tested three OS versions within days.
hpst Hoping the Librem 5
I did not know about this. I understand it should guarantee more privacy, but do you expect it to be more gentle on the eyes? Less dithering? Is it just a hope? Thanks!

Well software wise its supposed to be an open device running linux...to theoretically if we can find a dithering solution would should be more easily able to apply it there than to some closed blob in a commercial mobile OS. "If". But it could also be a moot point if they choose bad hardware. It's just a possibility at this point because it's not being built with our issue in mind and we won't know until they deliver.
