single black vertical line - G2 Q&A, Help & Troubleshooting

Hi, since all threads about screens and lines are about multiple lines I decided to make a new one 'bout my single black vertical line problem. Like vaguely noticable in the image at about a quarter from the right of the screen all of sudden that line appeared, no overheating or anything before. Weirdly enough I had this before but it suddenly disappeared, without even rebooting it was just gone, but now it seems here to stay. How can I find out if it's a hardware or software error? running Spiderio 380p 1.2f, rooted, stock kernel
-edit- how weird went to the movies to take my mind off it, and returned to find the line gone, weird huh? although there's no more rush but I'd like to know what caused it.

aaand, it's back! Was absent for over a year, but now it's back, switching ROM/kernel didn't help. Currently on tesla 5.1.1 with llama kernel, what the hell causes this?!

static lines/ glitching

Anyone else had any graphic glitching?
i was using inparisv4 i have been getting the odd little graphical glitch,
At first its just a small; a flash here and there, but recently the entire screen has be glitching for about 30 seconds at a time (Full on like a no signal telly)
Searched in the forum, and a few people had the prob when flashing the touchwiz interface. they solved it by flashing to samsung ota and then back again.
I tried that i thought it was fixed but a noticed small glitches just once.
Anybody know whats causing it?
I am really freaked
Screen Glitching
I had a new "re-furbed" tab that within the first 30min of use exhibited this. Then the screen went dark and it never booted again. I believe that this is hardware related, and from what I could tell from my research, it happens on stock as well as rooted tabs. I sent mine back to get another "new" one, and hope that I do not have this problem again as the tab is exactly what I was looking for.

[Q] Camera problems.

Hello
I have been having some problems with the main camera on the A500. It has different tints to it. Sometimes the picture seems to be divided in 4 and all 4 squares have a different hue to them. Restoring to factory settings seem to take care of it for a while. Initially I thought it was "skype" that messed it up, but it is not.
I just restarted the tablet and the camera is giving me a yellow tint, with a clear horizontal stripe about 3/4 inch wide through the middle.
The tab has stock 3.2 on it.
I was wondering if anyone has experienced similar problems and if there was a solution to the problem.
Thank you
Well, I would think the problem seems to be some app/apps you have installed. Based on when you do a factory reset, it goes away.
I would just do another factory reset. Then verify it went away. Run it for a couple of days WITHOUT installing any apps. This will probably rule out a hardware issue.
Then install apps, 1 at a time. Use the camera, and look for issues.
Thanx. I will give that a try.
I traced it back to Swift Key X keyboard for tablets. How is that even possible?
Also yahoo messenger is another one that ruins the camera. As soon as I install any of those apps and reboot, the camera is back to normal.
Does anyone out there use either of those apps?

So, everything is ok?
Rule #1,
Stay away from apps meant for phones.
Yes, they "may" have tested it it on "1" tablet, then gave it a clean bill of health. Maybe.

I thought it would be ok. But after restarting a few times, the camera colors are off. I'm going to root and install a custom 3.2 to make sure it is not the hardware.
Spasiba for all your help )
any news about this problems.
it seems that my iconia has the same problem- i never noticed it because i dont use the rear camera.
i sold it it today and the guy who bought has described something like what you folks are talking about
the strange thing is that i had done a clean boot before i sold it, and the buyer hasnt installed anything on it yet.
im waiting to hear back from him after he tries another clean boot.
anyone else have any ideas ?
I'm having the same problem. I don't use it much, but the camera was ok before. When I tried using it this weekend, it showed colored translucent squares on the sides. It is not a config problem, as there are no effects turned on. The front camera works 100%. I will post a sample when I get home.
If I change the "whites" config to Incandescent, it kind of solves the problem. Sometimes, the squares appear, but not for most the time.
I believe this is not a harware issue, unless that whites configuration is made with hardware (highly doubt it). I don't have Swift key, or Yahoo messenger, or any other apps that use the camera (other than Skype, but it was already installed when the camera worked).
Did anybody find a fix to this? It seems it is only a problem on stock 3.2.
Edit: not an exclusive 3.2 stock issue, it appears that custom roms have this problem as well.
I have the same issue after ICS ota upgrade...
Any ideas?
I haven't had the issue since the ICS upgrade. Only tested once or twice, but it is working properly.
What I did to partially fix it was changing the White Balance to "Incandescent".

[Q] Screen flicker problem. Please help

I am experiencing a screen flicker on my Nexus 7.
It happens once every 5-10 minutes always in the same spot, across the bottom third of the screen.
I am running Paranoid Android 2.1.6 rom on it.
It is still within the two week exchange policy of the best buy where i purchased it. Yet, if i can diagnose the problem and fix it, i would prefer not to exchanging the unit.
Is it a rom problem or a hardware issue?
Can someone please help?
Much appreciated.
Define flicker.
If people here talk about screen flicker they refer to an issue where the brightness of the entire screen changes. It happens on low brightness and seems to be related to wifi.
What you're describing leans more to another known issue, namely the vertical stripe. It happens periodically and manifests as a single vertical line (in landscape) across the screen for a few frames duration. This seems to be a software problem and is reportedly fixed by flashing motley's kernel.
If your problem is really 1/3 of your screen flickering then to me that's an unknown issue and I would rma if I were you. Unless it's to do with your rom, for rom related issues you should check the thread. Can't hurt to try another rom before swapping device ofc.

Thanks so much for your reply.
The verical stripe is exactly the issue I am having.
Can I flush the motley's kernel right on top of paranoid android?
The vertical line is thin, it doesn't take up tbe third of the screen.

[Q] Nexus 4 Ghost touches

So I bought a used N4 sold as is because the seller said he had some issues with the ROM and the touch sensitivity and all it needed was a stock ROM flash. I took up the challenge and flashed stock 4.4.4.
While I'm at the home screen everything's fine, as soon as opened the app drawer there were random touches all over the bottom half of the screen. Some were shown in the center and many at the bottom left corner but most were just random. I mean like 7-8 touches per second. The same happened whenever I went into play store, Opera or Chrome. Didn't test it further since I decided to try another rom.
Flashed Purity ROM and at first glance it worked flawlessly. Not random touches in home screen, app drawer or settings. Then I flash Gapps and the same thing happens with Play and Opera.
The funny thing is that the problem persists but at different circumstances. Can't pinpoint the exact cause. Should I get a new screen and try? Or maybe something else is at fault there?
I've been having the exact same problem as you. It started after I replaced the screen and the usb flex.
Ghost touches 1-2 each second only on some apps (none on homescreen or settings). I noticed that it happen in 4.4.4 app drawer but not in the 4.2.2 app drawer. I got almost no ghost touches on 4.2.2 messaging app also. It happens in almost any app, like play store, dropbox,chrome....
I thought it was the battery so I replaced it, but it did not fix it.
I have been trying to troubleshoot the problem but I ran out of theories. I wish the best luck to find the solution, as I almost gave up on it. If you happen to solve it tell me.
I think i found out what's causing this issue.
My theory was that apps with a lot of white would trigger the ghost touches. So I tested with flashlight screen apps that only show white on the screen. As expected the ghost touches only started to appear when i turned the flashlight on.
Therefore my theory was correct.
In my case I will contact the seller that sold me the screen to see if I can get a replacement.
I've had the intermittent touch screen issue, just above the capacitive buttons and also the ghost touches.
Started about 2+ weeks ago.
I reverted back to the stock "HOME" launcher instead of the Google Now launcher and that seemed to have fixed the issue.
I will have to keep an eye out to see if it lasts.

Hi everyone. this is my first post. i may make some grammar mistakes, because english is not my native language.
I found a solution for the ghost touch issue on my nexus 4, so maybe it can help who is having the same problem.
1- Download and instal the NOMone Resolution Changer on Play store
(this is my first post here, so i cant paste de link here, but you will not have trouble to find it)
2- when asked, Allow superuser
3- open the app and change the height resolution to 1250. (it worked for me, but make some tests to see if you need to disable a bigger part of the screen to avoid de problem)
This is not the best way to keep using your phone, because you may lost a part of the usable screen, but worked for me.
Thanks!
I workaround this issue avoid using undervoling in the kernel, and avoid lower temperatures in phone, yes as you read ... this issue give my crazy when my phone was to hot and I tried to cold my phone using one ice cube in screen and back, the temperature of the phone down but ghost touches appears again, so played some videos to warm the phone again and dissapear again.
Don't ask me about how it works, or relation with screen, digitizer or battery, I don't understand but help me to workaround the issue.

Left Third of Screen Flickers On Gray Image

Hey all.
So I got my MXP about a month ago, as my faithful Nexus 6 has long been deteriorating (#RIPshamu), and I wanted to try something a little different. I love the device and have almost gotten it tweaked and set up just the way I like it. However, I'm currently facing an issue that I can't seem to fix.
When I have a dark gray image on screen, such as the dimming when you pull down the notification bar over a white screen, the left side of my screen flickers rapidly from dark to normal, as if changing brightness. It is most noticeable on higher brightness settings, but plenty present enough on lower ones anyhow. I have made sure that no odd display tweaks in GravityBox are interfering with system presets, and I can't figure out what might be causing this.
I'm hoping it is software-related; I bought the device off-contract and without warranty, as I do with all my handsets, but if the problem is with hardware I should be able to fix it on my own so long as I know what part is causing the issue.
I'm running TruPureXMM with FrankenClark kernel. (systemless SU, magisk/systemless-xposed if any of that matters to you). Can provide logs upon request, but things seem normal to me at first glance.
Anyone else experienced this or have a fix?
I too am running TruPure and Frankenclark. I've been having a similar issue with the display, except it's the bottom half of the screen that is dimmed. I've also noticed that the 'dimming' takes on vertical lines of color depending on what the screen is displaying. The 'dimming' has consistently been transparent for me.
I originally thought that it may have started because I changed some settings using kernel adiutor, however changing those settings back did not fix the issue. I've yet to try returning to stock. I've also noticed the same display issue on boot up and in TWRP, which suggests a hardware problem, not a software one.
Some research online suggests that there is a known display bug with the Moto pure, and that the temporary fix is to reboot, but that doesn't solve the problem for me.
I think I'll try reverting to stock first, and if that is unsuccessful, then I'll try to reseat the display connector.
