Hey guys,
just got my 1+1. Ran some tests.
During the gamma detection tests in the Display Tester app https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&hl=de I experience a constant and overall display flickering during several tests (e.g. the third one). Normally, and as I know from my Nexus 5, the flickering stops immediately after swiping to the next test. In my case, it stays in some cases. I already got feedback from another user which does not have this with his 1+1.
I also get those flickering with the first viewing angle test.
What do u guys think about this?
Thanks!

I'm facing flickering in my google pixel 3xl. You found any solutions?
Does anyone else have the same issue as myself, which is the horrible autorotate issue? By issue I mean the phone refuses to rotate all the time. I find myself constantly rotating my phone in circles both horizontal and vertical as well as a combo of both. Sometimes it will rotate but takes a decade. Any thoughts or fixes would be appreciated.
Yes i do but the issue only started after the last update i believe.
I too have same issue also I wish I could set battery saver to not instantly turn auto rotate off.
I also experienced this issue
My (temp) solution: if u rotate ur phone the rotation icon on the navbar will appear and you can press it. Auto rotation on this phone is f* up
Have the issue since day 1. Fierce annoying when watching YouTube.
Yes YouTube is the worst culprit

i've never had so many annoying problems like the the screen brightnes or dodgy rotation on a phone. Seriously dissapointed. I previously had a LG G6 and despite the performance difference i really like that phone much more than op7 pro right now. Still... after 3 years

I too came from a G6 which I loved. Between this anti rotate and lack of pocket lock function, maybe I should of just got the G8.
It has pwm even on full brightness. I tried the pwmfree app https://forum.xda-developers.com/t/app-amoled-pwmfree.3898070/ but it still hasn't fixed the problem.
Doesn't it bother you? My eyes hurt while looking at the screen.
I've read a bit about it on the link you've provided. How did you know if our phones have it? I am quite interested in this!
You use the camera from another smartphone or another device to look at the screen of the a52. And you change the shutter speed or exposure in the camera until you will see the bars pulsating on the screen of the a52.
Oh well then it seems like most of my phones since 2015 or so have had that, and I've never really suffered from headaches from it, not that I've noticed.
You can't notice it consciously, but some people, including me, are affected by it. The thing is this could easily fixed by samsung, but they wont do it. Other companies have removed the pwm effects on their amoled screens.

Damn that sucks, especially when you know its an easy fix from the OEM to implement.
One thing though, from what I've read off the PWM Free apk page, it uses a transparent black overlay and increases its opacity as you decrease brightness. If that's the case then you could use Twilight to acheive the same goal, right? Just max out the brightness and turn off auto brightness, then use Twilight as your brightness adjuster, turning the bluelight option down. Could that work?
The weird thing about the a52 is that it has pwm even on max brightness, so probably twilight wont work as well. I will try it later though. Same problem on the premium samsung range: https://eu.community.samsung.com/t5...been-addressed-on-the-s21-series/td-p/2641628

Yeah, it still flickers even at full brightness. Maybe setting it at 60hz could fix that? I'll try it later to see if that could work. My previous phone doesn't have that issue at full brightness, so I'll gauge the difference based on the difference between the two.
I use mine only on 60hz and it still flickers.
Yeah, I've tested it and there is a difference between 60hz and 90hz, but the flicker is still present.
Edit: I also re did the test on my old device, a J7 Pro, and it stops to flicker altogether at peak brightness. So yeah, this phone has very prominent PWM.

Yeah, that's why samsung should do something about it. Because we still have flickering at max brightness, we can't use other software to correct the issue.

I suspect you didn't actually have the brightness set to maximum. This cannot be set manually, but is only set when the ambient brightness sensor (front camera) is illuminated by a very bright light - the sun, or a very bright flashlight. The brightness of the display is then visibly increased above the normal maximum.
Well, if the max brightness can't be controlled then it's not relevant. In this review https://www.notebookcheck.net/Samsu...ntly-more-affordable-without-5G.539956.0.html they tested the pwm on the display with an osciloscope and it shows that when you manually set the display at 100% brightness it still has pwm. This is one of the worst pwm out there, and a shame for samsung to do something like this.
is a shame unless samsung make a change in the firmaware the a52 is a pain in the eyes i need to sell mine now i cant play any video game unless i want a eyestrain
Pwm sensitive here.
Samsung A71 was OK pwm 240 hz.
Samsung 21fe was OK pwm 240 hz.
Samsung s6 edge was OK pwm 240hz
Mi 11 ultra not OK pwm 480hz. Not OK even with anti-flickering or pwm_free / oledsaver app. Mi 11 ultra has Samsung display E4.
I really don't understand. Maybe is the highs and Bottoms in the amplitudes.
Works well on my galaxy s8

Hi. I realised the negative effects last year after a year of using amoled display on redmi note 10. It gave me headaches and also my eye power changed from 0.5 to 1.5 for both the eyes in just less than a year. I do 3 hours of use a day. That's how I learnt about PWM and the headache it gives to people.
edit - REDMI NOTE 10 died a week ago and I am searching for a phone which doesn't have PWM issue in it. For past 7 days I am using LCD screen and my eyes feels a lot better.
Just got my phantom black, 12/256 exynos version delivered today, been using it since this morning and I noticed that on mobile data I have little to no connection even though the 5g icon is stable in the Taskbar, as soon as I connect to wifi everything runs normally. I also had the purple glitch when touching the fingerprint sensor but solved it by disabling the dinamic animated lock screen wallpaper and putting in a normal, static one.
Another issue is that the phone locks itself (goes to lock screen) while browsing the apps (just like double tapping on home screen) but not while using any app.
I hope this is just firmware issue since they are shipping all the phones with the same firmware region based but maybe they still need feedback from some carriers (hence the mobile data issue) and also the display glitches I believe are nothing that a firmware update wouldn't fix.
P. S. : in these first few hours I didn't get at 1 hz refresh rate

With my xiaomi 12 pro if the screen brightness is dim it doesn't go to its lowest refresh rate. Increase the screen brightness and see if it goes to 1 hertz
I am having exactly all the same problems as OP with my 12/512 Exynos version. Now wondering if it is hardware or software issue with the screen glitching when using the fingerprint sensor. The glitch only occurs when using 3088x1440 wqhd+ resolution and dynamic animated lock screen. Position of the screen interference is always the same but can differ in size.

I envy those who received their device already, over here they will be delivered next Friday so we have to wait a bit longer. However I don't envy the issues you guys are having, fingers crossed I don't have to return the device shortly after I get it in my hands.

That’s most definitely in need of a screen replacement. That’sa hardware failure. I would think one could get that fixed for free

What's interesting is that the guy reported the problem only when using WQHD+ on youtube. When used in say gallery the problem was not there.
I've found this guy's post with details on our national samsung group

Could this also be a YouTube thing also? Like how Netflix has to certify certain devices in order to use HDR content. Maybe these new 2.0 panels need to have apps updated to work with them.

They forgot to mention one thing. The adaptive refresh rate only works, if your brightness is above 8% or ambient light sensor reads more than 40 lux.
So if you are some like me, with low brightness and low ambient light, get ready for your battery to dissappear as it will be stuck at 120Hz...
on some forums it is mentioned that on Vivis setting for display, the problem does not occur anymore; can you confirm?
anyway, the fact that these artefacts are not displayed when in FHD setting, shows that it is not a display problem, but a software or GPU
I've posted this in a separate thread. I don't think my issue is linked to the screen issues described here. I have a flashing green pixel. Seems like hardware. See the pics.
I have a mountain of problems too, with S22 Ultra black 12/256.
I've got:
Overheating and rebooting in my pocket when doing nothing
Random hanging whilst scrolling down a long list
Intermittent flashing green dots (I think four) across the screen
Horrendous battery life (had it for only 48 hours, but still)
S-Pen sometimes doesn't fire the Air Actions menu when removed (or basically just doesn't notice it's been removed?)
And not really a problem, but after 4 generations it still can't record HDR and 60 frames per second, when in 4k.
This is a huge disappointment, and the fastest tech return ever from me.

Poco X4 Pro 5G screen issue, I'm facing a recent issue with Poco X4 where its screen keeps "flashing" in shades of black that aren't completely black. like trying to adjust the color or something. From what I've noticed, this only happens when I set the screen to 120hz. This was probably caused due to pressure I did while leaving the phone in my pocket but that same day I updated the Android version to 12, so I wanted to know if there is a possibility that this is a software problem, someone is facing the same problem?

Yes, the same thing happens to me when the brightness is at 50-60% on a dark background it starts to flicker and it is not amoled black, it would be a software problem since many users have the same problem with the Poco X4 Pro 5G

From what I could read in this topic, the problem is that the screen does not show the true black of amoled screens, which is not my case, so much so that I tested the solution with Oreo Colorizer but it didn't work, but I've seen it in other topics some people talking about the screen flickering, including a user saying that turning off 120hz solved the problem. I hope that both issues are software related and that Xiaomi fixes this as soon as possible. Anyway thanks for the reply bro

Well, I noticed the problem the very day my phone was updated to Android 12, so it's really a software problem. I don't know how long it will take for Xiaomi to resolve this but I hope it will be soon
