Hi all,
Have been investigating some sources of eye strain and headaches with the PIxel 6, none of the PWM apps work for me, but it's been suggested that temporal dithering employed by the device might be at least a part of the problem.
Does anyone know if it's possible to turn this off in software? if rooted possibly?
It certainly seems that some older ROM toolkits had the ability, but they've long gone.
T.I.A.

I would like to see some solution for Pixel's 6 PWM as well.
I have also tried multiple apps. They help a little, but the issue with Pixel 6 is that it flickers even on 100% brightness.
I do wonder if it it even remotely possible to force the device to DC dimming or there are HW barriers.

Odd issue i've got on my Z Ultra, easy to replicate by doing the following, bring up chrome, click the address bar, with nothing entered in the text box, but then type something, an the white box drops down, with search suggestions, I can see the brightness increase on my screen, clear the text box, brightness dims back down very easily by staring at the keyboard while this is happening.. is this a hardware issue, or software related? anyone else notice this? very strange. its like more white content on the screen, the brightness kicks up.
Seems normal from what I notice. If it bothers you, turn off auto brightness.
It's part of Sony's dumb LCD optimization gimmicks
It's equivalent to auto contrast used by TV's and LCD computer monitors
You'll notice your brightness goes down when much of image is dark, and you'll notice the brightness goes up when viewing white images
This doesn't happen on custom roms based on Aosp (like slimrom which I use aand prefer)

Wow this is crazy, I just noticed my phone doing this a couple of days ago, and here's this thread. While I do find this dimming "feature" a bit irritating, it's hard to complain about the screen on this device. It looks so damn good.
This feature is called optimized backlight and you could disable it in settings on android 4.2.2 (correct me if im wrong) but since android 4.3 sony removed option from settings menu and they enabled it by default, unfortunatly you cant disable it unless sony returns this option in new android version or if you downgrade to android 4.2.
Sorry for my bad English
I'm using a stock BLU R1 HD running Android 6.0 and within the last month, give or take, my phones brightness has randomly been spiking or plummeting before evening out into something legible. I also use Twilight(With pro unlock) and I have for years. I have disabled Backlight Control in the app. I have tried to go into my settings and disable Adaptive Brightness, but it will not stay disabled and turns itself back on as soon as I leave Settings. I've recently installed Lux but the problem persists. I've been googling it and all the responses I find are from 2015, give or take, and most apps regarding brightness have also not updated since around that time.
The frustrating part is that most of the time when it changes I'm not even moving and the light around me is not changing. The problem actually occurs more in normal, indoor lighting than it does in darkness or bright sunlight, and I've been careful not to cover the front camera, where I think the light sensor is, just in case I was the problem.
Does anyone know what I can do? How I can either fix Adaptive Brightness to stop randomly changing my brightness for sometimes 10 to 15 seconds before going back to where it should be, or how to disable Adaptive Brightness so it will stop turning itself back on?
I'd prefer not to root my phone, so please don't suggest it unless there really is no other option. I've ruined several phones that way in various ways and have concluded that rooting is just not for me.
I have a 2 years old Samsung Galaxy S9 plus.
Sometimes, when I lower the brightness of my phone or the brightness goes down on low light conditions as Adaptive Display is 'ON', a bright green color keeps flickering. If I increase the brightness again, it will go.
I did whatever the internet told me to do. I factory reset the phone, enabled the 'Disable HW Overlays' in Developer Options etc. Nothing solved the problem.
This happens only very rarely. Most of the times, my phone will be fine. Very rarely, the flickering occurs.
I took it to the nearest Samsung service center and they told me that i may have to change my phone display. It costs around Rs. 19000.
My question is, if it is a display problem, why it happens very rarely? I want to make absolutely sure that this is a display problem before replacing the display.
Will this cause because of any other issue?
@jayeshbabuav
Do some troubleshooting to make sure the flickering is a problem with your Android’s software, instead of hardware - here: the OLED display. I think it has to do with device's GFX driver - keyword: Screen refresh rate ( Hz ). If refresh rate is too low then flickering occurs because there aren't enough updates per second.

Don't have a Samsung Galaxy S9 Plus phone, hence can't tell you.

is there any chance this is a battery issue?

If this were the case, the screen of a mobile device or laptop being on low battery would flicker all the time. Think about ...
As said: It's a misbehaving app or phone's GFX driver that causes screen flicker.
hey, i've just had this problem too yesterday, with my xperia xz3 which has an oled screen. It flickers like crazy on low brightness, and gave me a CRT like effect when i turned it on or off. have you found the fix to it already? or maybe you changed to a new phone?
Hello all,
This has been an issue since I got the pixel 6 at launch. When playing videos, the shadows appear washed out. It appears to be some sort of gamma shift or HDR tone mapping issue. This happens when in google photos, chrome browser, imgur, even other apps. (youtube is fine).
I've confirmed in person this happens to other pixels one of which was pixel 6 pro.
The issue is recorded here:
I tried changing the color setup under display options in system settings, turning off H265 in camera settings, booting into safe mode, forcing 60hz refresh rate, but it still washes out the videos.
This does not happen with videos shot by other phones, for example my wife's iPhone shot video then sent it over to me and the gamma shift does not happen...
Strange thing is, in Chrome while playing the video, as soon as I swipe up from the bottom to open the recent apps, the video jumps back to normal as seen here:
https://imgur.com/a/Va3l5fQ
I reported this to google, and their chat support to me to fully nuke my phone to factory....
Does anyone have any idea why this is happening, and could other Pixel 6 users verify it's happening on their devices as well ?
Thank you

I seldom shoot video with phones and usually don't like to reference reviews. But from what you described Dxomark's summary about video performance is looking to be spot-on.
Google Pixel 6 Camera review: An outstanding performer in its segment - DXOMARK
The Google Pixel 6 camera displayed an outstanding performanc and is currently the best option for photographers who prefer smaller devices.

My experience with dark objects in still photos has been somewhat similar. Recently I couldn't get enough detail photographing black camera bodies I'm selling online. Even with direct light from a daylight LED lamp I ended up using night mode. Every speck of dust showed up which wasn't ideal either.
Over all, though, I like the Pixel 6 camera.

Did you ever find an answer to this? I'm having the same issue... though it's not for every video, just in certain programs/websites.
Cheers.
I've been able to remedy this in chrome by turning off HW Overlays in Developer Options.
It's still an issue in Google Photos.

Sorry if I didin't understand it at first, the toggle to disable HW Overlays in the developer options will always turn off again, at least in Pixel 6, so that's what confused me

Huh it stays on on note 10 . In that case i am not shure how u can keep it on. Can u elaborate on when it turn itself off back again?
Weird, after I turn it on, I can go to any other screen on the phone, if I come back the toggle it´s off again, maybe it´s a bug on my end, here´s the example
Hi, apparently the Activity Launcher doesn't work for MIUI 13/ Android 12. At the same time, the phone use PWM and has terrible flickering, has anyone found a working solution to the problem?
Thanks!

Activity Launcher, despite the name, is not an Android launcher. It is a tool that allows you to launch and create shortcuts for hidden apps/services. It's popular because it allows modifying the "Anti-Flicker Mode" setting available in some ROMs but hidden from the Settings App.
Nova Launcher, as an Android launcher, cannot enable DC dimming. I don't think DC dimming is possible with this phone at the moment.

Thank you very much for the clarification.
It's a shame that there are no solutions to the screen flickering problem for this lovely phone. Interestingly, the Xiaomi Redmi Note 11s uses the same display, but there the flicker is much less and appears below 54% brightness only, while here it is even at 100% brightness, which is terrible for the eyes...
I haven't actually observed a flickering problem. I'm on MIUI 13.0.9 (Android 11) and can't even observe it at low brightnesses. I keep my display refresh rate at 60Hz to improve battery life, I don't know if that makes a difference? It's not a hardware issue with your device is it?
Use a camera on another phone, set it to pro mode, and choose a shutter speed of about 1/500s. Now point the camera at your phone's display and start dimming it. You will see black bars running all over the display. They are not visible to the naked eye, but at the same time your brain indexes them and if you stare for a long time they will give you a headache and damage your eyes...
This is called PWM and is characteristic of AMOLED screens, which is why they put so much strain on the eyes, unlike IPS screens, where the image does not flicker at all, regardless of the brightness of the screen.
btw my phone updated to android 12, is it possible to downgrade it back to android 11 or is there no such function in the menu?
You could probably flash the old firmware through adb, you could open a new thread and see if anyone has done it?
