hansennnnn recently I noticed that android 13 also do migraines. I had galaxy s23 and when he launched he had Android 13 which didn’t do anything but one year later something happened and I can’t use him without migraines. I’m not sure what is the safe version but I think Android 12 I good for me.

      twomee

      what type and brand phone that use android 13 that safe for you ?

      can you screenshot what is kernel and date type android 13 ?

      for one year you use s23 with android 13 no eyestrain or you just update android 13 after one year ?

      what is brand and type phone android 12 that safe for you ?

          hansennnnn I used s23 for half year with android 13 without any strain, with android 14 I started to get the strain. In the past I had pixel 6 with android 12 and didn’t got a strain.

          I suspect it’s something related to firmware and not software updates

              twomee so now you use your s23 with android 13 without eyestrain ? because CMIIW all samsung phone cannot downgrade because of binary system

              firmware update is like update android 13 to 14 right ?

              software update is just like update application like game chrome etc right ?

              yesterday i already downgrade to android 13 but today it still make me eyestrain,is possible is the dithering or pwm setting from android 14 still in android 13 ?

                K-Moss Android is not like Windows. Android cannot run arbitrary code. It can only run code in a signed APK file. Android is inherently secure because of this, new Android levels have very little to do with security and are almost entirely cosmetic and UI changes

                  I bought a Motorola G54 5G phone because it has an LCD screen without PWM.

                  As soon as I updated from Android 13 to 14 I noticed the strain on my eyes which obviously comes from temporal dithering (which was implemented in Android 14).

                  As there is no way to downgrade I sold the phone, bought another G54 (with Android 13) and blocked all updates right from the start.

                  What can I say? I never ever had any phone that is so good for my eyes! Highly recommended!

                  The downside is: I fear I will never be able to use any phone with Android 14 or higher.

                    Reinhard62 Do you have no problem with the same phone before update to android 14 ?

                    i have same case with you and i already buy the new one with same android 13 but still got headache

                        hansennnnn I can't say how the first phone was originally. Because the first thing I did was the update to Android 14.

                        Maybe in your case it's also pwm flickering. Luckily I don't have this because the Motorola G54 has an LCD screen. So with Android 13 it's perfect. I can read on the phone for hours without noticing anything. (And my eyes are VERY sensitive!)

                            I also get eye strain from Android 14 phones. I tend to think that temporal dithering has been implemented in either Android 13 or 14. Currently I use old phone from 2018, which has Android 9 and never update.

                              For me, it is the Samsung A70. I don't use it for games, so it's fine that it's old now.

                              For me the difference between dithering and no dithering seems to be between Android 13 and 14.

                              Reinhard62 i am sure in my case is not pwm because i can use the same phone before update to 14 with no headache and migtaine but after update to 14 i got headache.

                              i thought the solution is just buy a new one with same exactly type with original android 13 but weirdly the new phone make me headache too, so confuse

                              i get headache and migraine while use smartphone coincidencly when start eating oatmeal 2 times a day for my diet program for about a month before,is there any connection ?i google alergies oat make headache or more light sensitive or maybe oat have gluten

                              or is there anyway to disable dithering ?

                                  hansennnnn I do not think that oatmeal has anything to do with it.

                                  I can only say that for me the solution is a phone without pwm (Motorola G54 with LCD screen) and staying on Android 13 (not updating to 14).

                                    So you have to be lucky, because there are people who use two identical devices, the same model, Moto G54 5G, Android 13. One of them causes eye pain and the other doesn't. How to understand?
