I think getting a new screen/touch replacement is the best way to fix touch issues.

Just like what I said in the title, I'm about to get a new screen replacement as I heard newer batches don't have any touch related issues. I'm a hardcore gamer and I think touch is very important for me when playing games.
Already 3 months and 'software fixes' regarding touches is not working great.
My phone is from september batch and running 8.12.27 beta and facing touch lags around edges.
Clean flashed 8.12.20 now more multi touches issues under notch.
Is there anyone else who already got a screen replacement?
Any issues like screen bleed/touch delay/multi touch and so on?

Under warranty??

Yes

I also have the same problem but I'm on the stable Pie version of the ROM.

I still havent found any problem though. My screen does have a lil bit light bleed. Still,no touch issue yet.

buy a switch or something, you can consider yourself as ''hardcore gamer'' if you play un phone xD

I'm also facing touch lag around the edges.
The screen center is lag free though. Latest stable Pie didn't improve anything. I also have a little bit of screen bleeding around the notch.
Does the warranty cover this?

How about doing 'qi'test and see if it outputs iq on your Poco.
What ROM you using?
Any multi touch issues when playing tap intensive games like drums or MOBAs?

I think you might be wasting time because I'm pretty sure I've seen someone here or on Reddit say that they had their screen replaced and it did not fix the touch issue for them. Keep in mind after replacement that any of the beta releases from 8.11.23 on (except for the 8.12.27 update) have a new kernel which fixes the delay on the right and left edge and improves scrolling. So if you wish to test if the replaced screen did fix anything, use the stable ROM or the .27 beta to check that.

I must be one of the ones without the screen issue then.

What exactly is the touch issue?

I Got Armoured edition 128GB delivered yesterday itself. Updated it to MIUI 10.1.3.0 PIE and i am facing no issues as of now. No screen bleeding and no touch Issues.

I would like too to know how to detect those display issues.

Ofcourse I'll use the Stable ROM to get a new screen instead using beta.
I can replicate those touch issues on Stable i.e touch delay on edges.
It'll be useless to ask for a screen replacement using a beta just to find out all the store did was just change it from Beta to Stable to 'fix' the touch issue lol.

If you're on Stable pie, type 'qi' fast and most Pocos will output 'iq' even though pressed q first then i. This is touch delay issue.
If you're on 8.12.20 beta, theres screen freezes and multi touches under the notch if you tap and slide 2 finggers at the same button with a bit of force for it to occur. Screen freeeezes also happens where you cannot register ANY touches on the screen until you lock and unlock your phone

Well, I'm still not sure. Sometimes, I will do it quickly and output is "qi" but sometimes I do it quickly, output is "iq" but I'm not sure if I pressed "q" or "i" first, because of the speed. It's there any other way to prove it?
And if it have lags, who can feel those? Because I definitively not.

'q' then 'i' super fast and make sure you know what you are pressing first.
Or you can try 'p' then 'e' quickly see if it comes as 'pe' or 'ep'

Every Poco have it. Forget about it and wait for the fix or just change to another device. If you're really hardcore, I'm assuming you a PUBG gamer, you should know that gyroscopic is the best way to aim on the game and the touch issue means nothing.

I can confirm by testing it, that switching from 8.12.27 to 8.12.10 touchscreen fw the delay is improved. At least, according to the maximum speed that I can type, performing the simple test of typing q and afterwards g or q and afterwards i, with the 8.12.10 is always printing on the screen the right order of the letters I ve typed, thus qg/qi, but on 8.12.27 always the outcome was gq/iq. My device is made on Oct.2018.

Oh that's interesting. Some people here claim that newer batches don't have the touch problem yet you seem to have the exact same issue as my unit which was assembled in July 2018. Full four months and the issue still there... That is why I don't believe there are Poco users who don't have this problem.

I just don't know.
It's just that maybe some units aren't affected.
I heard some random guy in the Poco reddit got a pocophone around September and bought another Poco for her little brother 2 months after that and what happened is his poco has touch issues while his little brother's doesn't have any.
That's why I thought I'm gonna get a new screen replacement

faulty fingerprint sensor

I believe there are some issues with the fingerprint sensor.
I have enrolled my finger print and then noticed after a short while it then seems to not recognise it and seems to rely on the face data to unlock the phone. I actually think this happens more than people maybe aware.
I then register the finger again and after a while same again.
I've now noticed that when I try to register now that it accepts the first couple of presses to register and then stops and won't continue the process.
Hands are squeaky clean and so is the screen.

Yes I'm having the same problem too on my Chinese version with Google play pre-installed.. I thought I bought the Global ROM version but got suckered with the info saying "Chinese version with Global ROM Google Play installed" & even the Play store crashes quite often too.. Anyway, after this latest update it's been glitching my finger print & not reading it sometimes & my hands are clean, screen clean etc.. hopefully wen the stable Android 11 is released it will b fixed...

I have European version and i have the same problem. Annoying.
Luckily the face recognition is superb

Cover the front camera and try the fp reader. I've tried around 55 times and all were success. So no problem on my side.

Fingerprint sensor is intermittent - works well after reflash and then stops

I have a One Plus 7 Pro 5G Europe version running Android 10.
I find that the fingerprint sensor works intermittently.
So for example I have factory reset the phone and also have tried to flash the phone back to original settings. I most recently flashed the phone to a clean A10 about 2 weeks ago
After reset/flash the fingerprint sensor works very well and is quick to respond however after a short time maybe a week or so it doesnt work well, sometimes im pressing 3 or 4 times and it will say too many attempts.
As a test I just added a new fingerprint to see if this would help and Im having the same issues with it working intermittently.
I have to revert to using the pattern which defeats the point of the sensor
Any thoughts please
Thanks Bart

Note 20 ultra Smart view and another problem

Ive received my note 20 ultra around 2 days ago and successfully rooted it with magisk. Now before i rooted it and maybe even after, smart view and samsung dex was working. Now it just connects and disconnects. Ive tried resetting network setting and adding a code to the build prop nothing is working, hopefully somebody can help me out. Also another problem is when ever i turn on my phone after i fully powered it off it says [PDP] Back up files detected. What does this mean??

I'm assuming you checked the functionality of the device before rooting for a few days?

Smart view sucks with this phone. I sometimes get flawless functionality, sometimes it can't even find devices it's paired with before.

Yeah i guess but the thing is i had a oneplus 6t before this and it was working perfect, does this phone have just the normal screen cast by any chance?

For anybody facing the same issue all you have to do is add wlan.wfd.hdcp=disable to your build props reboot and your good to go

Question S22 Ultra bugs (mobile data/display/other)

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.

Some users have this very strange screen problem...

Some users have this strange screen problem .
Its random and it lasts for 1-2' sec
Anyone else?

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.

About the refresh rate, did you see this article?

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.
