Screen Issue multicolored dot cluster - AT&T Samsung Galaxy Note 8 Questions & Answers

All of a sudden a number of multicolored dots started appearing on the side of my screen. I called Samsung and they said I need to send it back, around 2 weeks without my phone. Anyway I can fix this without sending it back? Anyone seen this issues before? Any ideas?

Send it back, I had that same issue on my note 5. It started small like that and eventually took almost a quarter of the screen.

[Q] Screen is black but still reacts

The device is Samsung Vibrant.
So recently I replaced the screen and it has an annoying bright strip on its left side that randomly shows up from time to time, so I decided to reinstall the screen to fix it. After doing that the screen would stay black but it still reacts (it vibrates upon unlocking, etc)
Before I do anything else, I was wondering if anyone has encountered this and managed to make the screen work again, before I send it back. Thanks.
I think connection was failing and by replacing display it failed ...
yea probably. gonna send it back. thanks

[Q] [help] notification bar randomly opening

Hey guys,
Had my transformer for 2weeks now and loving it. However recently (first noticed it 2 days ago) the notification bar has randomly started opening itself. It doesnt happen on a regular schedule -sometimes it will happen 3 or4 times in a couple of minutes, sometimes only once or twice an hour but not less often than that.
It happens even when im not touching the tablet at the time so i dont think the screen accuracy/calibration would be causing it.
I have turned it off and off a number of times to no avail and Ive also tried a factory reset and even with no additional apps installed it still happens.
Finally ive tried it both with and without sd card in and it happens in both situations.
Oh, and the dock connector being attached or unattached doesnt stop it either.
Has anyone heard of this happening before and or have any ideas to solve this problem?
i get this too all the time. i'm not touching the screen and the notification pops up for no reason. sometimes apps open up randomly too, for example i get an email notification and the email app opens. very annoying when plugged into a projector whilst giving a presentation.
somebody must be able to help. I'm not rooted by the way and have no intention too.
Sounds like a hardware problem - the touchscreen registering fake touch events. Check for mechanical stress in the lower right corner.
Update
I probably should have added, like yours mine isn't rooted.
I also turned on the developer options for touch detection, and it's definitely detecting "phantom" touches in the bottom right corner so definitely hardware not software issue.
Unfortunately, yesterday I started having issues with the touch screen being unresponsive in the right third or so of the screen, so I've called Asus this morning and am RMAing the tablet anyway.
I'd suggest you do the same rob if it's still in warranty, in case its a prelude to larger issues like mine was.
interesting thanks both. i was weighing up an rma because my keyboard dock is getting very loose, letting the top of tablet move about an inch without hinge moving. i've turned on show screen taps and already seen one. thanks again.

[Q] Touch Screen Unresponsive plus White Horizontal lines

Hey guys and gals,
I have nexus 5 that is just about a year and a half old. Every now and then, when I wake up the phone from sleep, the touch screen becomes unresponsive and I see white horizontal lines running across the top. I have tried restarting the phone, resetting the phone to factory. The problem still persists. The only way I get the lines to stop from showing up and get the touch screen responsive again is pushing down on the screen hard at random location.
I have attached a video of the problem I'm getting. https://youtu.be/CzgZ1bcN1Lk
I'm suspecting its a screen issue and I need to replace the LCD panel, Digitizer, etc
Any help would be greatly appreciated.
Thanks!
You need to replace the digitizer (if I'm not wrong), I've encountered this issue before on my older phone.

Weird Korean writing on screen

Sitting in a theater, trying to keep the screen from coming on, when suddenly I got 2 lines of Koren on the screen and a button on the bottom in blue labeled OK. Took the place of my watch face. Had to turn it off and on to get rid of it. Did NOT hit OK. Anyone seen that before?
It is used by MRTIMEMAKER appwhich has a non-loclized part in it.
It just states to accept the recently chosen watchface. Pressing OK just loads it to the screen

Touchscreen randomly not working

Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
