[Q] Black line across screen - Nexus 7 Q&A, Help & Troubleshooting

Hello all.
So I received my N7 today and everything was working perfectly fine. I updated to 4.1.1 and that went smoothly as well.
Played around with it for an hour or so, and then .... suddenly noticed a black line on the bottom part of the screen (1px thick, about 7cm to the bottom). Rebooted still there.
Also I think the magnet inside the screen isn't working for me, as I can't turn the screen on using a magnet (I got one of those fancy cases)...
Anyone experiencing the same thing? Found a fix?
Thanks!
Mo.

Touchscreen Issue

Hi. I have had my Nexus 7 for quite a while now and so fdar it had worked perfectly. However today the touchscreen wouldnt work, even after many restarts. Then it suddenly started working again. I flashed back to stock and till then everything was working good again. However once I flashed a custom rom again the thouch screen got messed up and it was as if I was touching the screen when I wasnt. Does anyone know what's going on with my tablet ?
Thanks
I was mistaken when I thought it was related to software and I found the real issue. When applying pressure on the left side of the frame of the tablet, the screen will start registering touvhes on it's own. Upon using Multitouch Visualizer I noticed that after i pressed the left frame of the screen, the tablet would register touches on the far right of the screen on it's own. Is there any way I can fix this ?

Dead spot in the middle of the screen / Ghost Touch Bug?

Hey guys I got a problem with the touchscreen of my nexus 4.
So, today I noticed that my phone is doing weird things, like open up the clock app and swiping between the homescreen by itself.
And I realized that there is a dead spot (or row) that is not working. It's like 1cm in the upper part of the screen. (I think it's similar to this problem)
Attached you can find some pictures of the test I made.
As you can see the lower part is working perfectly, but the upper part is not (I drew a solid line!)
Any one else got this problem? Do I have to return it? If so, where?
Edit: I did a bit of research and it seems to be something called the "ghost touch" bug... Anyone got this issue before? I think I have to return it

Replacement screen bottom 1/4th of screen unresponsive. Need help!

Hey guys so earlier this year I dropped my phone and the screen cracked. I ordered an lcd + digitizer from ebay and installed it myself. Everything had been working fine for a couple weeks but then randomly one day I woke up and the bottom 1/4th of the screen didnt work. Also, my screen is not very secure onto the device. I can peel off the lcd if I desired. I put double sided tape on all the places that a guide showed me but the screen just doesn't seem to stay in which causes dust and other particles to get in between my screen. Could this be the problem?
Some things i forgot
This started off with only a small portion of the bottom part of my screen to stop working. But then it turned into my whole bottom 1/4th of the screen not working. However, the first time this happened, I fiddle with the screen since it comes off and just moved it around and the bottom 1/4th worked again. However the problem reoccurred and I can't seem to fix it this time.
Thanks for any help!
Edit: Forgot to mention that I tried to open the phone again and press down on the digitizer pins to make sure they were secure. Still didnt work
sorry for posing this as it offers no solution
but just to say i have the same situation on a nexus 5.. came compete with frame.. worked for a week then bottom 1/2 inch stopped working
My upper 1/4th of the screen stopped working... Seems to be like a fairly common issue with the LG G2 and some cases appeared all of a sudden without drops or water, some other with a bit of liquid or slight drop to the floor.
In my case I think it was due to excessive moisture when I used the phone while sweating profusely.
A screen replacement is at hand right after I get my smartwatch

New Note 3 screeen showing unusual behaviour

7 days ago I have purchased this new note 3 N900 , the screen today is acting in a weird manner.
Here is what happened, I switched on the phone and then there was only the wallpaper and a dark triangle on the right side of the screen, I rotated screens but the thing remained the same, that is only the background with a dark triangle on the right side of the screen with a little flicker so I had to restart the phone.
Now it's working fine, please suggest should I get this phone replaced, is this some kind of hardware issue.
Also I had purchased a cover for the phone which was actually very hard to remove and I applied a lot of strength on the right side of the screen to get the cover removed, can that have caused the problem.
Also is there any app which I can use to check is there is a problem with the screen or not.
Thank you for your time, please give your valuable suggestion.
I'm running stock android 5.0 the same software that came out of the box.
The screen roughly looked like the image attached below -
Forgot to mention above that earlier I also had this issue where the all apps button on main screen turned to blue while everything was working fine and won't change to normal so I had to restart the phone again in that situation which did fixed that problem.
Would it be possible for someone to clarify that is this some kind of problem cause due to applying excess pressure as the Urban Armor Case I have purchases was really really hard to remove so I had to apply a lot of strength on the right side of the screen, it was so hard to remove that even the official back cover came off with it, can that have caused the issue or is it just a software problem.

S5 Screen glitches, flickers, duplicates parts

Hi,
My dad has S5 G900F for about 3 years and never really had a problem with it. But now the screen sometimes glitches, bottom half of the screen goes black
when he's in the browser and once he moves the screen it disappears. The upper quarter sometimes duplicates itself, screen splits into 4 parts, other parts duplicate as well,
the phone freezes and then when he reboots it the screen turns into these old TV glitching errors. Once it boots up, it slowly goes down while the upper half is blacked out and his
wallpaper is showing. Photos in links.
Once it's fully rebooted and he gets through the lock screen which freezes for a moment it works just fine.
Do you have any idea what it could be? We're guessing that there could be a motherboard problem but we don't really know. It's an old phone and replacing motherboard would
literally cost more than the phone now so we're just curious.

Hiya, guess what, I had exactly the same problem with mine. Ended up replacing the screen... But before I did so, not only did I notice the screen glitching and having "snowstorms" and suddenly rebooting, parts of the screen ended up having black squares (loading animation for instance) which went away soon after but kept coming back. So now I've got a new display (got it about a week ago) everything's been fine until I noticed that black square appearing again (only briefly while the loading animation was displayed when shutting the phone down). So I think it must be a motherboard issue... Hasn't gotten as bad as it used to be though, not having any other problems... I know this isn't exactly helpful, just felt the need to post this.

It actually helped in knowing that he's not alone who had this issue. It sucks that the motherboard is slowly giving up after 3 years of use but I'll definitely tell him about replacing the screen. It's kinda cheap after years. Although he's looking for an upgrade now. But seriously thank you Hopefully it won't get worse for you.
Update 2 Dec:
The screen no longer works. It just shows TV like error although it works in the background .
