in acessability->display-> reduce the white point. That should help you a lot.

Staycalmsyndrome

Been using a Xiaomi Redmi Note 3 Pro with Tianma panel and Android 7.1.2 builds (7.6.15 firmware) for a while but i tested a Mi Mix 2S (JDI) and noticed that the ghosting effect when scrolling in browser is pretty bothersome, a Samsung Galaxy Note 9 burned my retinas(even with hw overlays disabled) and a Huawei Mate 20 with RGBW JDI LCD still gives me discomfort. Any suggestions?

Staycalmsyndrome Maybe Xiaomi A2 with Tianma display

So. In retrospect, my eyes got tired using the iPhone 7+ but didn't ... strain ... per se.

I've now used the HTC 10 long enough to set it up, running Android 8.0 (it got Oreo, who knew?), and so far I'm mixed on it.

First of all, the battery life is not awesome. Doing initial setup and fooling around for 30-40 minutes has me down to 78%. Not stellar.

Second of all, it's... hard to focus on. Easier with my glasses off. This might be something I get used to, it might not.

It does NOT induce instant strain. I'm trying hard to find words to describe this, but...

The HTC m8, when using Lollipop, has ZERO strain. As did the iPhone 4s.

When I use the iPhone 7+, I can tell my eyes are working to focus but it doesn't hurt per se. They just get tired. The next morning they were a little bleary. I need to do a repeat evaluation.

When I update the m8 to Marshmallow firmware, it is INSTANTLY more painful. Actual eyestrain occurs.

This HTC 10... is just harder to focus on. The strain is slower to build, but I believe it is there. I don't know if this is a factor of the OS (Oreo), firmware (unknown), or screen technology.

I also have to turn the brightness up pretty high to be comfortable, lower brightnesses are very hard to use on this phone.

Night mode seems pretty useless, it just changes the screen to orange.

I may spend more time with the iPhone 7+ and render a final verdict, but I'm leaning towards ordering one from Verizon and getting used to it.

Gurm Can you check HTC 10 panel? If is Sharp ou Tianma?

Also on Iphone 7 reduce the white point.

Gurm

tfouto It's Tianma.

Maybe it might be better to test that iPhone 7+ with some print as well. You were playing a game which has much larger objects to focus on, so in the efforts of making it a fair test, read a bunch of articles on the phone and see if the strain gets noticeably worse!

Gurm

MagnuM Will do.

Unfortunately the Essential Phone is now discontinued: https://www.techradar.com/news/its-the-end-of-the-road-for-the-essential-phone-but-a-successor-is-coming . You can only purchase from another retailer or on Swappa. Just got mine and will play with it.

I just learned of Amazon Prime Exclusive Phones including the LG V35 and LG G6 https://www.amazon.com/b/ref=sv_cps_2?_encoding=UTF8&node=14613304011. Amazon should have 30 day return policy on them.

OnePlus 3 is still really good for me. I can look at that phone the longest out of any of my non e-ink devices. The camera kinda sucks, and the battery is pretty degraded, but at least I have something I can look at.

Basically, it’s been the real deal for me, at least using @KM settings.

ryans

degen What are the settings you use?

Also I see a type of "flickering" in this Pixel 3, I'm guessing PWM from the OLED display but not sure: https://youtu.be/JRV-1WnyUOk?t=141

Spent some time with the essential. Screen definitely seems to hurt my eyes almost immediately, I suspect because of PWM. A shame because it's a beautiful device. Wonder if a PWM free kernel would make this device usable.

JTL

ryans That reminds me of PWM from OLED :/

tfouto

It seems that Iphone X and XS at 50% brightness presents, the less variation in PWM.

Guys hello,
I recently had a dizziness and headache problem for the first time with my Samsung S8.
It was so annoying that i had to sell it.
Now im in a dilemma, i dont know what phone i should buy.
Im between Pocophone F1 and Huawei Mate 20 lite.
If anyone has an experience with these phones please let me know, it will help me very much.
Thank you.

ryans

iliasb Hard to say. What phones have you used previously that didn't bother you?

@Gurm Let us know what you pick!

Final verdict ... I sold the HTC 10. I had lingering eye issues and focus problems for the remainder of the day after using it. It ... might ... be something I could eventually get used to, or maybe not.

I'm ordering up a brand new HTC One m8 with a fresh battery (still available from Amazon and eBay) and going to use that as primary while I experiment with other phones (might try an M9).

noigmn

I'm thinking of trying an m8 or m9, but my old HTC One m7 makes me sick. Did they use a few different screens in the m7 too?

It's running lollipop 5.01, but it's a custom ROM (stock android). I couldn't detect any PWM or brightness variation with my S7 phone camera. It's rooted so I might be able to run something to detect the panel.

tfouto

noigmn yes they use. I had a good Htc One m7 for my eyes. Then i need to repair the GPS, and they also for some reason also exchanged the screen. That new panel was terrible. I sent the phone back with a letter explaing that the new panel was afwul and want the old one back. They replace it by a new one which was good. It was similar to the first one.

At least your story had a happy ending.

noigmn

tfouto do you know what the good screen was? I might replace the cracked screen on mine.

Also, I tried to identify the panel on the m7, but devcheck doesn't show the panel type. Anyone know why? Is it an m7 thing or might that be due to the ROM I'm using?

noigmn

tfouto Do you still have your HTC One m7? If so, could you check your panel type?

I checked my panel type and it is:
SHARP_RENESAS FULL HD panel

Just open /proc/last_kmsg in a text editor and search for panelid to find it.

It should be same as mine or else one of:
Samsung M7 C2 OR
Samsung M7 C1

tfouto

JTL Yes until now that i the HTC one is almost useless. The touch dont work, the speaker also.
