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 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

      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

      12 days later
      6 days later

      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 ?

                  hansennnnn

                  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

                    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.

                      ensete because in my case i have a same excatly phone after got update android 14 become eystrain and headache,before update i use the same phone almost one year no eyestrain at all so i believe its software issue for me.do you have same experience like me ?

                        ^ yes, that's right, BOE — somehow, despite BOE typically being hated here, this remains one of the most comfortable panels I've ever used (at least while running this OS)
