Vertical lines ppearing on my phone. - Redmi Note 8 Questions & Answers

Situation: My phone sometimes shows a vertical line in the middle part that is red and black. Two lines. side-by-side. Just a line. It just shows for a brief moment(approx a second or less) and will disappear.
Replication: I am not so sure if I can replicate this bug, if I can call it that way, however when the line appeared I was loading multiple tabs from google and reddit. I think the phone was just 'stressed' in some way or the other. Again, I am not so sure.
More info: My phone is MIUI Global 11.0.4.0 (PCOMIXM), bought it a month ago. brand new.
Anyone having this kind of problem?

[Q] Touch screen acting weird

When I press on the very bottom of the screen (edge of the glass), it acts as a click to about 1/3 the way up the screen. This is annoying by its self (and doesn't seem ROM related) but also my screen sometimes locks up, with a point at about 1/3 the way up the screen, and horizontally in the middle, and I can't do anything until I lock the screen and leave it off for a second. More recently, but related to this issue, the keyboard when typing hasn't been accurate. I've tried to type 'a' but got caps or 'q' instead, and I get letters I didn't press.
This is not ROM related, as it started happening on CM6 about a week ago, and I've flashed Ava V9, Myn's 2.2, FrEaKy Evo, and CM6, and I have tried stock kernels, and Kings. It seems to lock up more when plugged in also. I've been watching the forums and I haven't seen anyone else post about this, is it just me? It seems very hardware related, but if there is a fix for it that someone knows about, please let me know.
If I get around to it I might take a video of what I'm talking about, but probably only if it's requested.
I'm currently running Myn's Two-Point-Two with King's CFS #11 and am still getting the issues. I've rebooted, and wiped cache/dalvik, flashed new roms, reflashed, nothing.
I am having the exact problem, except that the spot that keeps getting phantom clicks is at the very top of the screen, so the drop down bar starts freaking out. I downloaded the program 'dotty' and it is showing that a touch is being registered in the expect spot, so I'm pretty sure it is just an issue with the screen hardware. I want to take it to a sprint store and see if they can replace just the screen instead of getting a brand new phone because I have so much stuff downloaded on it and I don't want to lose data/settings.
It happens a lot, but then I will have days at a time that it stops happening...its just very strange.
Its good to hear that I'm not the only one with this problem. Currently running rooted stock froyo. unrevoked forever. Original June 7th release device.
same here...was happening witht he W/q as well...but when your viewing a white page you can see a light on the screen brighter than the rest...

W/q? what are you talking about there?
also the light bright spot is completely unrelated: evo developing a light spot in middle of screen
Screen burn possibly due to overclock
Bright spot in the lower right of screen

I downloaded dotty, and it's saying my spot is at:
X: 159.6
Y: 363.5
and P which I'm assuming is the size of the area being touched at .937.
I tested P and it does seem to be how big of an area you're touching but the biggest that I could get using my thumb was only .235, so it's a huge area and constantly in the same spot. Some times it gives me two points or one a bit up and to the left.

Ghost touches in upper third of screen

Hi.
My Z1C seems to have a similar case of faulty display as described in some other threads here, but actually a bit different. The phone is stock, not rooted, running 5.1.1
Whenever I do something, there are ghost touches in the upper quarter or third of the screen. They only happen when I am not touching the screen myself. It happens no matter what I do. When I browse internet, it clicks links, when I scroll contacts, it calls people, when I am on facebook it gives likes etc... It seems like the more demanding task the phone is performing, the more ghost touches.
I turned on the developer settings and the "show pointer location" option, which leaves track of the last touch on screen, so I can research the issue.
I found out that when the phone is on home screen, it happens very rarely or not at all - the track of my last touch stays until screen turns off.
When I jump into the touchscreen service test, it does not happen at all. I can draw a line around the whole screen and it stays higlighted indefinitely.
In lock screen, it also doesn't happen.
I tried it in Sketch and it confirmed what I thought, when I was just sketching, from time to time a dot appeared in the upper part of the screen, but when the phone was downloading or installing in the background, the screen literally had seizures. I touched and released and then a storm of dots started to appear around the top part of the screen. It stopped after 5+ seconds, and after another input from me, the screen got another fit, drawing more dots.
I don't have any experience, but I think that since the problem doesn't happen constantly and it doesn't even happen at all in test mode, it could be a SW mistake.
I have found this thread https://forum.xda-developers.com/showthread.php?t=2691849 and I'm willing to try, but 1) my phone is still under warranty and 2) I have never done a root so I am not too eager. Do you think I should try that? Or has anyone found another solution for this problem?
Thanks.

As You have warranty, I would strongly suggest that You go for a repair. I had the same issue in beginning, ghost touches appearing randomly, going away only after reboot. I was rooted and xposed, so went full stock without restoring any apps or data from internal storage, yet the problem remained, thus ruling out the point that it was software problem. And then after a week or so, that much part of screen stopped responding to touch entirely. You can see details over here, Another user had same problem as Mine and had the same end result,
OK then, I'll go for a repair. Thanks for the tip.

I am having exactly the same behaviour as you described .
Ghost touches happening on the upper part, and triggered when a demanding task is running.
Actually I didn't realized completely about this, I thought it was just random, but right now after I saw your post, I tried an app similar to Sketch while upgrading apps or playing a video in the background. And dots in the upper part start appearing crazily.
Did the phone repair solve your problem ? Mine is not in warranty, so I'll have to pay for it.
But also in my case, before this thing happened, I got some water damage and that upper quarter of the screen stopped responding.
After replacing screen+digitizer I got this very specific behaviour you described.

In my case, I realized that I bought (probably) a badly re-fitted phone. Display's backlight was visible around screen panel edges, where I'd say it shouldn't be visible at all. I decided to return the phone and got a refund.
Sorry for not being able to help you.

Ok. The aftermarket screen I got has that issue with the screen edges also. Very probable you are right.
In my case I water damaged myself. It seems that after 2 years of intensive use, waterproofing is gone, by accumulation of slight hits or so, never had a single crack on the screen. I read many posts reporting this happening, even with much less use time.
Too bad, I loved the phone, but I'm afraid that sending it to repair will mean to change the PCB or similar for a complete fix, which can come to a ridiculous price.
Seems it will be time to move on...
Yeah. If you want it fixed properly, you'd need to send it to Sony, and for the money it would cost you, you can probably gen a new phone. Sadly, similar phones aren't made anymore.

Another widespread screen issue? Not responding in bar across middle

Alright guys so I've been using pixel for about a month after getting one with little to no blue tint and tonight I noticed screen not responding in middle of screen. I'd choose a Facebook message and it wouldn't pick the conversation I tapped on. So I go to display tester and perfect line across screen where I can't get to register. See photo. Anybody else seen anything like it?? This is like my 7th pixel and I've about had it with them!

I have extractly same position as you. I thought It was only me.. yet same position prove it was manufacturer defects.. worried all batch affected.
Unless we see a bunch of people coming forward with the issue, I wouldnt be so quick to jump to "all batch affected".
100% here.

Small flickering line observed at left side

I'm not sure how to describe it - I may be paranoid or something but I've observed that sometimes while scrolling on the screen, i see a very thin line flickering on the touch screen for like 0.05 second then it goes away. It happened on the middle left side of the screen.
If anyone has observed this issue let me know as well. Thank you.
I've seen this as well, it didn't occurs everytime but you can see it, sometime on the left side close to the notch, sometime on the middle of the screen..
But until now, nothing to horry about, lets see in the next 3 months
Alright glad to know it's not happening to me only.

I've written about it with detailed description in the following post

I think we have send bugreports using "Feedback" app.

My G8 doesn't seem right lately

So my phone has been working great for over a year now or so but all the sudden just recently it has been looking kind of weird. It has lines wherever the words are like if you're reading Facebook or typing something out it'll have five lines. 3 through the words and one line on top and below. It looks like halogen lights are behind it. Like you can tell some are darker and some are lighter. Also when you unlock or lock the screen, there is a temporary flash of green. Sometimes the green is small and sometimes it's a big flash of green on the whole screen. Example of what is happening in the linked youtube video.

Just do a backup and try a factory reset for now
