So i suppose this is hard to explain, but I've noticed that every now and then the left side of my screen begins to emit what I suppose is best described as noise. If I reboot the device, the problem goes away, and I have only experienced it about 3 times since I got the device. Has anyone else experienced this, or knows if this is an issue that I should be worried about?
FYI I have rooted my device, but have not done anything else.
Thanks for any help

I saw this for the first time today. Appears to have been triggered for me by the microHDMI.

Just to be clear, do you mean that your phone doesn't register your fingers touching the screen on the left side of the phone sometimes?
I would suggest downloading the free app "Touch Test" which shows a grid that not only shows where you are touching, but the path of your slides across the screen. If the phone begins to act up again, you can open the act and see if and where the screen is cutting out in the grid. Aside from that, it might simply be that you need a replacement and its coincidental that it was acting up along side you running a 4.0 rom.

That is the oddest thing I have ever heard lol
It really might be a hardware issue man...I can't think of how it could be the rom. I mean, sure you might occasionally
have an unresponsive touchscreen....but only half the screen working?? That's just weird Oo I'll keep looking around for answers though man
but thus far I've found very little.
Good luck

I have a video but i'm new member i can't send link to my post. I will sent to your inbox. tk
Okay, so that anyone else that happens to come to this thread is on board, here is the video that shows his problem:
http://www.youtube.com/watch?v=5xDolJhmDog&feature=youtu.be
As you can see in the app, if the origin of the trail is on the right side of his screen, the swipe is recognized across over to the left without problem...if however the origin is on the left side of the screen, no touch is recognized until he reached the middle of the screen, at which point it becomes recognized.
I am still looking around for a similar problem, but thus far have few ideas. Typically, the screen either is totally unresponsive or momentarily unresponsive...never half and half, and especially with such weird rules. By this, I mean that obviously the left side of the device is capable of recognizing touches, since if he begins at the right side, it does just fine....the only problem is if he originally touches the left side, then it doesn't recognize it.
My guess: it could be a kernel issue.
I would try the following:
Pull battery and reboot. Take out any external SD card.
Back up what important apps or data you have and try a factory reset.
You can also try some the options below:
1. Reflashing the kernel.
2. Try a different kernel if available.
3. Factory reset and full wipe and flash a different ics or cm9 rom to see it the problem persist. You can try to isolate the issue to hardware or firmware.
4. Full reset and flash back to complete stock to see if the problem persists. If you are fully reseted and back on stock eclair or froyo and the problem persists, you may have to open up the device to check all the connections.
sometimes a bad battery may also creates some problems
Now i'm using xerxes custom 2.3.6 gingerbread. It's ok but i don't know why when i use ics. I can use half left screen

This has been bothering me for some time now, every so often my screen will start to flicker but then goes away. What does It mean at times it goes all black then I see stripes from either left or the right sides...
My screen does this at times also. Although it is pretty annoying, it doesn't seem to cause any issues that I have been able to find.m it seems as if it happens when running graphically intense games/apps/or web pages. But, there really is no rhyme or reason to when this occurs. It is completely random in my experiences. I just hope it isn't a sign of failing hardware...

what firmware are you on? if its happening on any rom it may be a hardware problem? try flashing a different rom and see if it cures the problem.

Hi all
Sorry for a newbie question.
I have a Sony Z Ultra which I really like, but recently the screen sometimes just starts rolling for no reason. I cannot read anything, and it often does not stop. I turn the screen off, then on, and it often doesn't show anything but then it does it is still rolling. I have to hard reset, and even then have to do that a few times before it starts up normally. It seems to be happening more frequently. Any ideas on what I can do?
Thanks so much
Craig

Rolling back? Screenshot

It is more like rolling upwards, like an old tv that is not tuned to the channel properly (I am showing my age here because I still remember that)
I cannot take a screenshot because everything on the screen rolls, so cannot access the screenshot function or anything else for that matter.
I have found that when it happens I bend the phone backwards a little and it stops. This makes me think that perhaps the case may be slightly bent from a drop or from having it in my pocket which is somehow causing the problem.
It is not doing it now; I hope it won't return

From what you describe it sounds like your flex cable is causing the issue.
If that's the case, I could be wrong you can take it apart or return it to Sony. I'd just buy a new one. Sounds like a flex cable issue to me
A final development in the story of my phone. The rolling came back, got worse, and then I had times where I would push the power button to light up the screen out of power-saving screen off mode, and nothing would happen. The back-light would light up, but just a blank, black screen...
I sent it to the repair center and the quote came back. It would need a whole new screen.
The cost was going to be pretty high, so I looked online and bought a whole new phone for only 60 cents more than the repair quote!
I just hope my new phone lasts longer than the old one
Hi guys,
Recently my Nexus 9 would occasionally give me a messed up screen with around 3x10 mm white or other color blocks piled up the entire screen. And flashing.
Sometimes even with shocking noises like biiiiiizzzzzzzzzzzziibibibibibibibizzzzz
It would disappear if I use the power button + volume up combo to force reboot.
Sorry don't have a photo or snapshot yet. I'll try to take one if that happens again.
That did freaks me out when it happened the 1st time.
It just pops out from no where. I've tried to locate where's the cause or the problem but failed.
I just wonder if this is some sort of hardware failure? It does gets quite hot after the screen is on for a while.
Please if anyone ever had the same issue?
And please please please do tell me it's not something wrong with the hardware!
Thanks.
Have the same issue. Seems to happen more likely when the battery is like 50 % or less.

Sounds like you might have the same problem, in which case: yes, it's a hardware problem...
Hey guys,
I got my Redmi note 2 yesterday and I'm having trouble with the touchscreen. sometimes it seems to be perfectly fine and sometimes it doesn't react properly. It seems to be worse in the right half of the screen. Sometimes I start scrolling and it works fine in the beginning, then the screen stops detecting my finger and when it detects it again, it opens the thing that my finger is on instead of scrolling.
I'm not sure if this is a hardware of a software bug.
Would calibrating the screen help? If so, whats the best way to do that?
I would usually try flashing a clean stock rom (the one it came with has some bloatware anyway) and test if that resolves the issue, but that's probably not the best idea if I decide to return it.
thanks for your help

Try entering in the MTK Eng. Mode, then go to Hardware Testing->TouchScreen->HandWriting and try drawing some lines crossing the point where the problem occurs.
A friend of mine had a Nexus 5 with a malfunctioning touchscreen, doing a similar test we noticed that there was a full horizontal line where the touch were not detected so every vertical line we were trying to draw were broken on the point where the bad line were crossed.
Obviously in that case it was an hw fault.
EDIT:
Reading your post again, it seems a behavior caused by lag, so maybe it's a sw problem and not an hw one, especially for the fact that "it opens things instead of scrolling".
Does it always happen in the same point/area? Or is it totally random?

I already did that and the results are very inconsitent. When I first tried it, it started drawing a line as it should, then it stopped and started again half a centimeter later, then it stopped again, and it pretty much went like that from top to bottom of the screen (at least on the right side of the screen, the left side worked better).
When I did the same test again, it didn't even draw lines, it just highlighted a few single pixels along the way that my finger was traveling.
And currently everything works perfect and smooth as it should.
It does kind of feel like a software-thing, but in my mind (correct me if I'm wrong) that should affect the complete screen equally and it just doesn't. I tried pulling down the notification bar earlier, from the top right of the screen and it just didn't work. I did a few tries and nothing happened. Then I tried pulling it down from the top left and it worked fine.
As I said it works fine at the moment, but I guess I'll make a few screenshots and a video of the problem, when it occurs again.
Ok, so the problem came back and I was able to do some more testing and make a video (sorry about the shabby quality, but it'll have to do ).
youtube . com / watch?v=rKsponNr9lA
As it turns out, the whole screen is affected equally, so I'm pretty confident that it's just the software but I'd still like to hear a second opinion.
The thing that kinda throws me off is that the reboot didn't help at all...
So what do you think? Is it just buggy software?
I'd try contacting the seller and explaining him the problem.
Maybe he will ask you to flash a new rom to be sure that it's a hardware problem and not something that could be solved without a replacement. That's what happened with my first phone from China.
If not, you could ask him and I think he will authorize you.
