simplex i already downgrade to android 13 yesterday but it still make me eyestrain or maybe because of one week full eyestrain so it take time to my eyes ?i confuse depress,is anyone in here never experience it

is possible the dithering or pwm setting from android 14 still in android 13 ?

simplex

hansennnnn

It can be

But firstly, take a rest for a week. Eye-spasm has big tail: you will blame all "safe" devices

hansennnnn

simplex what do you mean " it can be " is

for because of i got eyestrain for one week so my eyes take time for cure even use "normal" phone ?

for downgrade android 13 is useless because setting from android 14 still there in android 13 ?

sadly i cannot rest my eyes from using phone because from monday until saturday 9 am until 5 pm i need use my phone for work

I think issue is pixel inversion algorithm which cause pixel flicker to prevent burn or pixel stucking

hansennnnn

simplex is there any setting or application to fix " I think issue is pixel inversion algorithm which cause pixel flicker to prevent burn or pixel stucking " ?

simplex

hansennnnn sadly i cannot rest my eyes

try to use old or safe device to let your eyes relax

nope, it is system code which update panel's chip. You need to get root and some knowledge for android core settings

The problem is, for example, your previous 13 android not modify this data, when 14 - does. Thats why after rollback, you can still have eye-strain ( 13 android exist with panel chip's firmware done by 14 android )

hansennnnn

simplex how to make panel chip's to android 13 ? is there any tutorial ?

Do you have experience same with me ? that your phone is safe but after upgrade cause eyestrain,after downgrade still cause eyestrain

if yes what is your brand and phone type ?

yesterday i already ask tehnician of authorized service center that downgrade my phone,he say downgrade make phone like new from the box so he say impossible that some setting from android 14 stil in android 13,he says its like format all of your storage and flash with the old android 13

simplex

hansennnnn ask tehnician of authorized service center

okay

then all you need is take your eyes rest and dont use " bad " screens

hansennnnn

simplex or maybe it is my brain need to adapt because of placebo effect ?

i dont have any phone beside this one, just laptop that i cannot take everywhere

or maybe the tecnician is lie ?is there possibilty to downgrade android but setting from new android still in old android ? any thread about this topic ?

hansennnnn It is quite common that new version of OS brings new animations, new text-sharpening effects etc. And these features can cause problems. The newest version of Android I can stand is 11.

hansennnnn

pavelbures i already downgrade my phone to 13 but still got eyestrain and headache,before that i use same phone with android 13 no eyestrain at all,i think there is dithering setting from android 14 that still there in android 13 even after downgrade,do you have downgrade os and still got eyestrain ?

i think the only way is to buy new phone with excactly same type and make sure not to update to 14 btw all batch of the same type phone will be have the same hardware and same software right ? while i save money for buy a new one,i searching for solution to disable dithering in here but nobody in here know a way to disabel dithering

My Trust TCL A30 broke, so now I am stuck using a phone that give me eyestrain. It has absolutely zero to do with flicker or PWM or blue light or any of the other nonsense people throw around.

I tried 4 other identical model phones, none of them worked for my eyes. I did a shell swap and still no help so it;s not the screen, it is either the video hardware or some difference in the OS

Just going to use my phone as little as humanely possible while I keep trying to find one that doesn't trigger my BVD. Every phone so far, within a fraction of a second of even glancing at the screen, my right eye tries to focus on something different than my left eye and causes muscle spasms in my face. I can feel my eye moving in and out.

hansennnnn

ensete do you already check android version and firmware version tcl a30 that you can use without eyestrain is exactly the same android version and firmware version with new 4 unit tcl a30 that you have been bought ?if you have swap the screen but still got eyestrain is definitly software problem

ensete

hansennnnn Same Android version (11) but that OS was upgraded, I bought mine when it first came out and never installed the system update, whereas the the one I bought was upgraded

What I am going to do is use the new phone to take diode readings off of so I can try and repair the old phone It stopped charging and was missing texts, so if I can repair it that solves my issue

hansennnnn

ensete i think you must try a new phone with excatly same os and same firmware with your old phone,because even it is a same hardware but if it have a different software it will make difference like eyestrain migraine etc because if some day your old phone got lost,you wont have another solution

ensete

hansennnnn Well, duh 🙂 That's easier said than done

I did do a shell swap and swapped the new motherboard into the old phone body (including screen) and it didn't help. So that proves it is not the screen, it's either a hardware difference with the motherboard, or a software issue (driver or patch level of OS)

hansennnnn

ensete motherboard has storage so it is using the same storage and os,try find new one one market place

edit today i got my new phone with excatly same type dan same os but i still got eyestrain and headache,meanwhile i can use my old phone zenfone no eyestrain at all but so slow and have only 32 gb storage so it is not my eye problem

maybe i think after update the screen a little bit blurry is it from dithering ?i depressss stress,i dont know how to solve this issue,just join telegram grup about ledstrain maybe find something about disablw dithering

ensete

hansennnnn motherboard has storage so it is using the same storage and os,try find new one one market place

The two phones have different update levels. And the GPU and GPU drivers could be different. They are the same "Model" but have different manufacturing numbers.

I have proved it is not the screen hardware, so that leaves the GPU hardware, GPU driver, or O as the culprit

hansennnnn

ensete i am sure in my case it is because of software because before update i can use same the phone with no eyestrain no headache at all,do you know how to disable dithering on android ?

do you have succes with one eye patch training ? is there a tutorial video how to do it ?

my lazy eyes in left my dominance eye is right than i cover my right eyes right ? how long a day ?if i close my right eyes is it the same with patch right eyes ? because is kinda embarasing using patch eyes in public room if closing right eye is the same with patch right eyes ?
