valex13 you should be able to manually flash the old firmware. I think on Xiaomi forums they post them there

      jordan it is very complicated as I have to unlock the boot, and to do it i have to get the unlock permission from Xiaomi. But they don't give it for hyperos firmware. It is very complicated process now.

        Hi. I also post this on another forum I found today. And I find this forum too. Can please anyone recommend good eye ache free phone

        I try new OnePlus 12 for few days and it causing me lot of aching eye and very strong headache. I try all brightness colours setting but aching eyes still too much. I cant use for more few mins because eyes hurt too much

        Before I also try honor 90, magic 5 pro, Xiaomi 13 pro, s23 ultra, Moto edge 40 pro pixel 8 pro all in1 year but I return all as same ache and headache

        I read review of OnePlus 12 which said good for eye but for me not true. I am now sending back too.

        Is any new phone with good camera eye ache free with no headache? I need good camera for pictures videos but I need headache free phone cause I use a lot for work things

        I was using a Hisense A5 procc until i bricked it. Now a normal Redmi LCd phone and it sucks. Especially at night. Will get the TCL nxtpaper 40 soon and see how that goes. if not good then ill buy the hisense a9 eink phone

          It seems like the HyperOS update for the Redmi 12 5G has slightly improved the comfortability of the display.

          The toxic backlight issue is still very present, especially at lower brightness levels, however, xiaomi have included a new "contrast" option within the developer settings. I've fiddled around with this (standard, medium, high), and i feel improvements after selecting the medium/high setting. The improvement is solely to do with the readability of web text. Web text appears more refined and easier to read/focus on.

          Still, the display doesn't feel 100% comfortable, especially using it under 50% brightness, but after the HyperOs update, there does seems to be a marked improvement.

          However, the HyperOS update has restricted disabling/uninstalling apps via ADB commands, which is a huge shame. This means debloating is now almost impossible. I think there is a workaround, but it entails creating a xiaomi mi account and registering the device first.

              vegeta97 I've had a negative experience with the Nxtpaper phones.

              They both use PWM, confirmed by TCL's tech team/customer support.

                  Redmi Note 12 5G Pro looks interesting for me: just small background discomfort compare to other smartphones that trigger strong reaction from first seconds

                    Vividblu99 really? sucks to hear that. Which model did you use? Am waiiting for the 50 models. So theyre not like eink at all? in terms of less eye strain i mean

                        I still think we need some sort of 'poll' feature where (within reason) we can list phones (maybe different polls per year as there are a lot of devices released) we can then all vote against devices to say who can use / cannot use them etc.

                        Query I've got for everyone though, on an android device you can use, please list the screen resolution and if it supports HDR / wide color gamut or not?

                        Download 'devcheck' (its free) as it'll say there under hardware display.

                        I have a theory that HDR and wide gamut uses more dithering, often on more budged phones with HD / HD+ (not FHD) we do not see HDR support so less dithering and less eye / headache pain?

                        Also if it has PWM, some people PWM does not affect but I cannot tolerate it or much HDR as its all flickering to me and flickering = severe migraine headache pain (any OLED based phone is very likely using PWM)

                        FYI Android 13 extra dim mode is similar to IOS reduce white point, makes screen even dimmer

                        Latest from me, Moto g23 possibly usable with time, symptoms not so bad with night mode / eye shield warmer display + extra dim mode (LCD HD+, no HDR or wide gamut, cannot detect PWM) surprisingly fast for a phone with emmc storage though.(android 13)

                        Moto g54 symptoms worse, (LCD FHD+, wide gamut and HDR enabled) unsure if usable long term (android 13)

                        Samsung A32 5G, totally fine (LCD HD+, no HDR or wide gamut, cannot detect PWM) surprisingly slow for a phone with UFS storage though, samsung bloat / launcher / OS issue maybe? (android 11)

                        vegeta97 I've had the opportunity to try both the 4G and 5G.

                        I purchased the 4G model outright, and returned it soon after.

                          Throughout all of 2023, the Honor 70 Lite was the least problematic handset I've tried, and has provided the most comfort.

                          It's followed closely by the Honor X8A, however the X8A display has a very high saturation/contrast, so it may not be suitable for everyone.

                          I've found both of these comfortable when using them at a fixed 60hz refresh rate only.

                          It must be said that the performance/specs for both of them are trash, but that was something I was willing to overlook for eye comfort.

                          Other devices that i've found comfortable to use in the past include the older Realme LCD based phones such as the 9 Pro, 7 5G, 8 5G, X50 5G. Everything realme has released after these has been uncomfortable.

                              Based on the good experience I've had with the Honor 70 Lite, I really thought the Honor X7B would be similar, as they share similar display specs (90hz/TFT). But I was completely wrong.

                              I've found the X7B's display awful. I loved the form factor though. It has a 6.8 inch large display, and has a nice grip and the handset is comfortable to hold. Also the sound quality was good too. But they've really messed up on the display. Very uncomfortable.

                                Yesterday I tested the Blackview Shark 8.
                                LCD screen but not good.
                                Under Opple Lightmaster test, it didn't show any flickering, but I had migraine and Eye strain.

                                  Aquila That is so disappointing to hear!

                                  Did you feel strain on both refresh rates of 60/120hz?

                                  There is something definitely wrong with these new LCD displays. I can't put my finger on what the exact issue is if it's not pwm.

                                    I just got OnePlus 12 but will be returning it. It gives me instant headache and nausea.

                                    I'll keep using my OnePlus 7T Pro and OxygenOS 11 (which still allows to turn on DC Dimming) for the time being because it's very easy on the eyes for me.

                                    Anyone replaced the original oled screen of the iphone 14 or 15 for an lcd screen? I would like to try it, it may work for us who are sensitive to oled screens.
