ensete you're lucky you can use 6. When HTC updated my One m8 from 5 to 6 I had to force downgrade and root the OS so it wouldn't pull OTA updates. They made HUGE changes from 5 to 6, at least at the firmware level on this phone. That isn't necessarily the case with all phones, though.
Google handwaves it away probably because it's device-dependent. The OS probably hasn't changed much about the display output...
I spent some time with my girlfriend's iPhone 7+ this weekend. It's really nice, eyestrain is slow to develop on it. She has a tempered glass screen protector. It doesn't have instant-eyestrain like the 6 did. I'm going to see if I can play with it for a longer period and maybe put one of those matte screen protectors from skinomi on it. If that works for me, it is a viable upgrade path for my now-3-year-old HTC One m8.
I can use Samsung s6 without any problems all day. And iPhone 4s as well.
I find it better when I use iPhone 6 at greater than 30% brightness with reduce white point setting (accessibility- display optimisations) set at 100%. I also use darker colours ON & have adjusted colour filter to provide a very slight yellow tint. This combo allows me to use the phone for a long time. The iPhone 5 I have however is absolutely perfect in as much as there is no strain at all. I also experience no strain on Xiaomi Mi Pad, but all their other devices like Mi5, Mi Max etc cause strain. Samsung is taboo for eye people
The M9 is ... not as good as the M8, but it shipped with Marshmallow so that might be the problem.
Have somebody tried LG G6, S8 or P10?
We have those only in our Mediamarkt, but they use some strong withe led-s in whole store so after few minutes i feel like on drugs. So it's impossible to test some thing. I think that LG should work for me but I don't have place to test it. I will try to order online and than return. When I see S8 on youtube it got PWM and some problem with red tint and I know now that color tint is also causing strain even if I'm using my old Samsung TV or LG G2 - small color change causing eye strain so I thing S8 will not work for me anyway.
On my iPhone 6s I have always used lowest brightness and when Night Shift became available I enabled that 24/7 and at it's warmest setting. There was an option in accessibility to 'Reduce White Point' but the effect was so insignificant as to make little difference.
The display was still way too bright. Recently I revisited the 'Reduce White Point' option and found that there is a sliding scale and you can really dial down the harshness of the light (believe this was introduced in 10.3). It's a huge improvement and I can use the phone for short periods to shoot a text or short email whereas previously I would not use it except to make calls which I did with voice commands.
It's still not a comfortable display and I can't get comfortable using as it can cause eyegraines which I usually associate with PWM but iPhone 6s does not use PWM..
Either way this new slider on 'Reduce White Point' is a big improvement.
I am iPhone fan since 3G. But I like other smartphones too. After 3G i cant use any high end smartphone because of eyestrain. I have problem with all flagships phones. I can distinguish ips display from the headache, nausea i get. I get a different type of headache from amoled. The only amoled i havent tried is rgb matrix. Pentile 100% headache for me. I dont have problem with ccfl. I thought i may try lg g flex the first one. Is it possible to order custom made display and fit it in smartphone? For example i would love a tn display like 3g's on iphone 6s for example. Has anyone tried anything like this or thought about it?
Here is another theory. One of the suspect of the causes of eye strain is the color profile or the color rendering, which this thread elaborates more in detail:
https://ledstrain.org/d/200-found-a-cure-for-one-machine-at-least/36
What if the same also applies for mobile phones? We have read reports that phones that were not causing eye strain (e.g. HTC M8), suddenly cause eye strain when the OS was upgraded, e.g. Android 5 upgraded to Android 6 (marshmallow). So the latest android OS must've added something or change the way the graphics are rendered that it is now causing eye strain.
If this theory is true, that means if we install apps that changes the color profile of the phone like CF.lumen, then there might be a chance that the app will override or eliminate whatever it is that is causing the eye strain in the new OS. The app also said that if the phone is rooted, then the app will work even better. Maybe in rooted phones, the app can override how the phone renders color completely?
Can someone give this a try? Especially those who has M8 or phones that were not causing eye strain before, but when they upgraded the OS, suddenly they get eye strain. I read there were a few in this scenario based on earlier posts in this thread. Let us know if our phone is rooted or not as well.
The problem is figuring out what changed from Lollipop (where most people were ok) to Marshmallow (where they weren't). We can say we suspect things like rendering and overlays and hardware surface whatchits but the reality is we just don't know. Nobody has found anything definitive that they can turn off and go "HA! IT WORKED!" so we're sort of stuck.
I know. Without knowing the exact cause, the only thing that we can do is trial and error. We take one theory or possible solution at a time, and try it out, and see if it works or not. And hopefully one of the theory or possible solution actually works.

Well, we can narrow it down to something to do with the way the OS renders content to the screen. The OS alone shouldn't affect refresh rate or flicker. It can affect dithering and color. Unless the driver subsystem was changed, that could do it to

That was me. Unfortunately those "color filters" don't change the way the dispaly render colors. It just changes the color it is displaying. For example, if you are sensitive to particular spectrum of blue light the display emits, f.lux and the like won't change that from being emitted. It will just add red and green to the color display to make it look less blue.
ICC profiles work by actually changing the way the display shows colors. Unfortunately Google has decided not to add ICC support to Android, which is weird since there already exists an ICC profile class for Java so it would be trivial for it to be incorporated into the OS, and color accuracy is a huge deal for photographers and have kept smartphone from really being considered high end cameras, but they have handwaved away the issue like so many people who do not suffer our symptoms. You can search the Android bug report/suggestion forums for ICC and see the discussions.
Kray Can someone give this a try?
I did already. I have a Moto G, zero issues with a Skinomi screen protector and Lollipop, massive eye pain when it was upgraded to Marshmellow. I tried every light filter app out there, changed screen protectors, adjusted every display setting, nothing worked. Ultimately I had to restore the phone to stock and root it to block the update.

Yeah, I know I keep harping on it, but honestly, the color theory is the only theory that actually would explain every instance of eye strain I have experienced from any device and/or lighting source.
The color theory might be a good direction. I always got eye strain when trying any other color profiles on my OP3 other than "Default" (or whatever it's named). So my solution was to not change the color profile. It worked on Android 6 ("Marshmallow") and Android 7.0. Sadly, on Android 7.1, this doesn't help anymore. Whatever "they" did with the other profiles in earlier versions, they now seem to do with the default profile as well.
I use a Samsung S5. Android has color management coming in O. To me that meams installing color profiles similar to icc on desktop but on mobile. I have really never had too much problem with any version software on my phone. It has an amoled display. only when looking at it while in front of my monitor does The strain happen on my phone. in a room, with lights off, is usually fine unless my eyes are super tired and i get the hangover my desktop system causes and my eyes are completely beat.
However, If i have other leds shining on my phone it can be an issue. From room lighting or monitor.
Im hoping there is more to icc profiles and monitor calibration than i thought. That would take so much mystery out of this. I am calibrating my monitor. See how that goes. a custom icc profile for the individual monitor in use.

I'm trying to dive more into the the world of color profiles but it is a bewildering topic.

Check the bottom. Romanian guy is someone i used to follow on twitter and is on the Android team from what I understand.

I talked to tech support from X-Rite and he said you cannot "edit" an ICC profile. You can only change the settings when making a new one. DisplayCal seems to beat out private commercial software from what i have read on Amazon, one comment on Reddit and other general forums it seems.
All this talk about IPS panels. I prefer the VA panel from Samsung. I go to Amazon and the 32 inch LG IPS has rave reviews, i got to youtube, people say its the best screen they have ever had, but IPS doesn't draw me in like the VA panel. its just to artificial while the VA panel is more like looking out of a window.
Also, here LG is apparently investing in OLED screens. I assume this is only for mobile devices:
https://techspecs.blog/blog/2017/4/26/lg-display-rumored-to-be-investing-in-mobile-oled-production
I read somewhere but can not longer find it but individuals from AU optronics, i think ceo actually, stating that they expect quantum dot screen to beat out OLEDs in the long run in terms of cost and performance i believe.
