JOSEUISLEY yep
LineageOS 18.1 made my 2016 Android comfortable again.
Rowe I'll try to buy a Xiaomi Redmi 3 to try with my eyes. Thanks for the answer.

JOSEUISLEY BTW, in order to install LineageOS 18.1 on the device you have to unlock the bootloader (which is a relatively annoying process for this phone, since you have to get an unlock request approved). I unlocked my Xiaomi Redmi 3 bootloader all the way back in December 2016 so I can't speak for if it still works in 2024. YMMV
(If you can somehow find one that already has any custom ROM on it, that would make things a lot easier, but I'm not sure how common that is)
The "Part 1" section of the answer to this post is pretty much what I remember doing (note that 3S and 3 are different phones, but the bootloader unlock process is very similar between them):
Note that:
- it's been way too long to remember what the factory stock ROM (MIUI 7 Android 5) felt like for me. I don't remember having any major issues but there's also a chance that it's not good
- every single other Android 5/6/7/8 custom ROM that wasn't 18.1 caused really annoying eyestrain
- specifically the LineageOS 18.1 (Android 11) ROM with HW overlays disabled is the only custom ROM I've found that doesn't cause the strain at all!
LineageOS 18.1 is the only ROM I can "100% confirm" from experience is strain-free
This is the ROM I used:

Also note that depending on where you live it's either possible or NOT possible to use it as a real "phone" with cell service in 2024 — in the USA, I was able to get a 3G signal on T-Mobile back in 2016-2018, but today, it only can be used as a "WiFi-only tablet" in the USA because of the 3G shutdown
If a carrier in your country supports the phone's 4G bands (which was never the case in the USA, even back then, but is more likely to be true in many other countries) there's a chance you can still get 4G signal on it though
If you're only planning to use it as a tablet (which is what I am doing) you don't have to worry about this cellular stuff
Thanks for the tutorial. This model is difficult to find, I didn't find it on Ali Express (I live in Brazil), I only found the Redmi Note 3, same year and same specs, but is not the same device. But anyway I'll try. I'm going to use it as a tablet on wifi, for calls I use a dumbphone from 2010 lol. Thanks for everything and sorry for the bad english.

JOSEUISLEY Be aware, there are both Snapdragon and MediaTek versions of the Xiaomi Redmi Note 3
Make sure you get the Snapdragon version
(MediaTek phones have an "image enhancement" system called "miravision" which from what I've read seems to cause many issues for sensitive users)
DisplaysShouldNotBeTVs supposedly disable hw overlays in developer settings turns off miravision but haven't tested myself
DisplaysShouldNotBeTVs Oh yes, the Redmi Note 3 that I saw is Snapdragon, I'll test it anyway. As we say in Brazil, whoever is in the rain is supposed to get wet. Thanks
jordan Well, is a good idea to try too. All tests are a hope. Thanks
Can someone try lineageos on Razer phone 2? Supposedly it uses a sharp igzo 120hz panel. Looks like they have a android 14 build one but seems like lineageos 18 is also supported which also is older of course. I would give it a try if I knew if dithering isn't present
i tried lineage21 on a pixel 3xl - not good.
Which kernel version is your device running with 'lineageos 18'?
So just for S&G's I went into my stock device, a TCL 20s, and went into Developer Options and checked Disable HW overlays, and I have to say, it actually made a difference. I cant tell if it;s a great difference but I could noticably see a difference in the display. I'll give it some time and see if it normalizes out into a useable device
Note this is on a Stock Android 11 OS, no Lineage or anything
ensete disable hw overlay can disable dithering ? what else setting beside disable hw overlay that can make difference ?
hansennnnn No idea about dithering, dithering has nothing at all to do with my symptoms/issue.
I can say now with confidence that even on my stock Android 11 OS, disabling the hardware overlays and forcing GPU rending has made a SIGNIFICANT difference and improvement, to the point when I can actually use this phone now as a daily driver
I noticed yesterday after disabling that option that the eye strain immediately vanished, but using the phone was causing significant stomach pain. I used the phone a few minutes at a time throughout the day, this morning woke up and tried the phone again, still getting some stomach symptoms but they are reduced. I actually watched Youtube on the phone for a good 15 minutes and had maybe 1% of the eye strain impacts it gave me previously.
I'm going to stick with it and see if I get complete symptom resolution over the next few days, but this is a huge discovery, assuming the relief holds up over time. I have another device that I need to re-assemble and will then try this on that one (A TCL A30) and see if it helps there as well.

ensete ok thx bro for the info, today i will try disable hw overlay and force gpu rendering and is there anything setting else in developer mode ? like color mode standard or warm or cool ?refresh rate setting ? % brightness setting ? saturation colour setting ?
btw have you try eye patching ?
hansennnnn I patch daily for Windows 10 usage for work
I have no other "special" settings set, my brightness is at 50% Color mode is standard, refresh rate is 60, no color conersion is turned on

ensete where is setting force gpu rendering in phone ? there is only disable hw overlay in developer optiion no force gpu rendering setting btw if brigthness 50 than you are same with me,it is not pwm issues because pwm 100 brigthness
patching is same with just close one eyes right ? because i cannot patching in public room
and patching the eye that dominant and let the other non dominant eye,lazy eye to see right ?
where is setting force gpu rendering in phone ? there is only disable hw overlay in developer optiion no force gpu rendering setting
They are the same thing. Disabling HW overlays forces the GPU to do all the rendering. You are looking in the right place, that is the correct setting
if brigthness 50 than you are same with me,it is not pwm issues because pwm 100 brigthness
PWN has nothing to do with my symptoms. And it is untrue that all brightness control is done via PWN. Some devices use PWM, some do not. Setting the brightness level doesn't make a PWM-less display use PWM. If you get symptoms from a PWM-less display, then PWN has nothing to do with your issue.
patching is same with just close one eyes right ? because i cannot patching in public room
I find just closing one eye to provide less relief than patching and keeping the eye open behind the patch.
And I don't get the "I can't patch in a public room" thing. Of course you can. People with eye injuries wear eye patches in public all the time. If a device helps alleviate pain, use it, who gives a flying F what other people think about how it looks. If they are the kind of ignorant a-holes who would make fun of someone for using a device to treat a disability, F them. They are horrible people.
and patching the eye that dominant and let the other non dominant eye,lazy eye to see right ?
I don't know, I tried patching the right eye and the left eye and patching the right eye offered much more relief so that's the one I patch
ensete have you try setting database editor : persist.sys.use_dithering=0 ?
hansennnnn Dithering is not an issue for me. I have enabled and disabled dithering on multiple devices and it never made any difference whatsoever. Maybe it is for you, but I do not care about dithering, it has zero impact on my symptoms.
