Screen flickering after new firmware (apg2)

Hi everyone,
Yesterday I clean flashed the new firmware (apg2 XAR) for tab s2 (2016).
After an hour of use the screen started to flicker, shifting colors everywhere on the screen.
After a reboot the flicker was gone but not sure if that was a "fix". If it happens again I will try to capture the screen.
Nonetheless I wanted to ask if anyone had something similar. Can that be a hardware issue? Or a software one? Maybe a graphic driver problem?
Thanks for any input.

Well if a reboot fixed it then you're good to go.

Touch issues / Sensitivity issues after Nougat update

Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?

Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.

I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.

On what device/OS?

Sprint Note 5 on Nougat

Did you try gloves mode? Does it work?

the same for me on 920cd and the same iusse using S pen

I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.

Anyone tried to contact samsung about the problem?
They dont know anything about it.

facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook

I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help

Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.

Screen flickering and artifacts.

Hi All,
After updating to Oreo got this weird issue, screen flickers every, roughly 2 seconds. Wit the times it also starts showing some color artifacts, freezing some parts of the screen and eventually going to complete gray-to-black flickering only. Anyone experienced something similar?
I'm thinking it may not be Oreo upgrade related just (unfortunately) some hardware issue.
Cheers

I've had similar issue after updating to oreo.
Half screen displayed artifacts.
Nokia replied to me saying that there is a bug in display drivers. Probably gong to update it soon.
Had to send it back.
Replacement works fine.

The left half of my screen is covered with black/white/grey artifacts. Sometimes after resetting or going back to factory defaults the screen goes back to normal again.
Running Oreo on a 128gb Nokia 8. REally hope it is software related (driver?). So far installing the latest updates doen't fix the problem.
Switched back to my old Samsung Galaxy S6 but man I miss my 8 already.

I changed the motherboard and I got ghost touch problem then I change the lcd and everything seems fine to me
I don't think is sw problem

I have the same problem today. As i received a call, display start to flicker. As i have all imp docs in my phone as i relies on NOKIA , I am as nothing. Somehow I am able to reset to factory reset. phone start works, but I lost all my valuable datas. How can one relies on NOKIa, who was one of BEST

mi 9 multi touch problem

My mi 9 seems to be able to only detect 1 finger. Completely wiped phone and problem still persist. Anyone with same issue or able to fix issue?

I have the same problem. Have you found any solution?

I have that same problem. Could you help

Happened the same issue to my Mi9. Multi touch was working normally but suddenly it stopped working while I was zooming on a web page. Then I made a factory reset but still didn't work. Today I updated to Miui 12 hopping the problem would be solved but still no success. I think this bug is related to Android 10 as I saw elsewhere someone rolled back to Miui 10/Android 9 and things got to normal. On the other hand this is not a hardware failure for sure since multi touch keeps working normally on apps running in game turbo mode.
So, has anyone found how to kill this annoying bug?
Thanks for any help.

ive been searching everywhere how to fix this. i already email xiaomi about this issue. still didnt find clue how to fix this bug. still hoping that xiaomi will fix this issue.

This issue is a shame for Xiaomi!
As far as I know the only solution is to downgrade to Miui10 and stuck on this version or take the risk to upgrade to Miui11 (not recommended for obvious reasons) or the fresh new Miui12. So far I've been using the "turbo game" thing to workaround the bug. I had to install some alternative apps from Google Play (such as Chrome Beta, other gallery app, Google Maps Go...) to use instead of the stock apps so I can use them with "turbo" and get pinch to zoom working. This is not the best way to solve the issue -- the ideal is to get multi touch back working again without the need to resort to any tricks -- however it works very well. Maybe one of these days I'll get some patience to setup the good old Miui10 again...

i also have this ghost touch on the upper part of the screen. it came same time as the multi touch issue. it cant even fix by game turbo. i cant even play games normally like moba or fps game. i dont know if its just me have this ghost touch issue. its a big shame for xiaomi flagship phone?

No news about this issue? Everything works fine with Pixel Experience in my MI9 but multitouch. I remmember I solved another problem (auto-rotate didn't work for the display) and I solved it flashing only last version of "persist.img".

Same here bro!
I bought my Mi 9 in February and everything worked well. I also upgraded to MIUI 12 with no problems at all, then suddenly multitouch stopped working.
If I flash Pixel Experience will the problem be solved?

No way, Installing PE doesn't solve the problem.
I'm going to try it with new kernels and FWs.

Try to flash MIUI 10... I read somewhere it should work, because MIUI 10 is built on Android 9, which doesn't have this issue

same i have this issue, i tried miflash. the only workaround are miui 10 and game turbo method.
also i have this nonresponsive part of the upper screen, right where most game analog button placed. idk if this "dead touch" is connected to this multitouch issue

This was the first and probably the last Xiomi I bought. Back to iOS. Bought a second hand iPhone 11 in mint condition. Working rock solid! Crap Mi9!!!

Have the same problem here!!!
Upper screen DEAD
Annoying ghost touch on upper screen
Have to type multiple times because It keeps ghost touching...
Can't sell the phone, because of these issues...
Miss my Galaxy note

Is there a fix to this issue now? GameTurbo enhances the touch so that multitouch works. There must be a fix to this.
