try to download "multi touch paint" from the market.
draw a line across near the bottom of the screen. you'll find it always below where u touch, compare to a line draw across the top of the screen.

Yup seems to be your the only odd-ball, just kidding i couldnt draw the thing either haha.
I get exactly the same behaviour when I draw a line right over the touch-buttons and when I do the same at the very top edge of the screen, can't see anything that looks misaligned.
I have that issue,too.
That happen most likely when I turn my phone side way and try to access the bottom icon on the home screen. The touch screen has 30% chance to be out of alignment.
the line i draw just slightly below where i touch, that is around 2mm, sleep/reboot won't fix it.
Hey Guys,
I wonder if someone else has experienced the following: When you use your mobile during charge it's hard to use swype or "slide" through your apps since the display "jitters". I mean that when you try to do a straight line on the display it's not possible.
It's the same as with the issues the HTC HD2 displays suffered from.
It would be great if someone could confirm my experiences with the GalaxyS display.
Cheers!!!
quicky
Defective unit? mine doesnt do it.....
Well... don't know, however I didn't realize until I tried to "swype" a message. So tapping an Icon or similar "actions" work perfect. It only happens on swyping or e.g. when you slide in Launcher Pro and keep finger on display... then it doens't hold still but jums around all the time :-(
Trying to lower the top bar is practically impossible... Anyone else has this problem? Could this be a problem caused by the screen protector?

I have the same problem but my problem is not limited to just the top part. i am having trouble with taps and swipes across the whole screen
Me too, I noticed my knock on wasn't working at all, but knock off worked fine...Then I noticed that if I drag the notification bar down really slowly about half inch down it just snaps up as if I lifted my finger, almost like its not detecting touch anymore when it reaches that section. My phone has worked great for 3 weeks, what could be causing this all of a sudden?
Is there a charger in the dock?
Lots of devices get touch screen issues when charging. (I have to double tap everything on my Tablet when it's charging). Some have bigger issues than others. Depends on how good the battery is shielded.
I almost never notice it on my G2 though. Only a tad. Depends on how stable the currency is in my house (The problem is almost non existent at my home. At my mom it's just like my tablet. Have to double tap everything)
Could also be because of a magnet or something in the car dock.
Now I know this problem has been asked before but after some extensive searches I can see there are no clean fixes for this.
My Nexus 4 (Android 5.0.2 LiquidSmooth ROM) has started showing ghost touches at the bottom part of the screen. I know there are a lot of explanations available such as digitizer not working, battery being too old etc. But I'm not interested in these hardware issues/fixes.
I have isolated the area of effect as the bottom ~160 pixel height of the device. I then proceeded to use the ADB shell command
wm overscan 0,0,0,160
which removed that portion from the UI. This fixed the effects these phantom touches have on the apps or UI. But a problem still remains that these ghost touches happen in too many numbers and this leaves other usable areas of the screen insensitive to touch. I am guessing this is due to the multi touch limit being reached in that bottom unused part itself. Multi touch testing apps dont pick up touches on the top part of the screen
So my question is, is it possible to remove a part of the screen from the System itself? Ideally a thick black bar of unused area, leaving me with a shorter yet fully working screen? Or atleast is it possible to turn off touch response in that lower part of the screen so that it doesnt max out the multi touch limit?
My Nexus 4's is same too
I think, that ghost touch will work from Screen Digitizer. My Nexus 4's screen digitizer was non-LG's digitizer, it was fake. I need to change that digitizer
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.
Hello, been visiting the boards for a long time, but I didn't register because I had nothing to contribute really. <.<
I currently have a i9505 running on cm13 6.0.1.
Last night when I wanted to reply to a text I used the right side lock screen shortcut that's set to messaging the circular motion thingy messed up the edge of my screen. (I didn't realize until later that it's not actually a hardware issue if you ask me.)
Some pictures, screenshots don't register anything:
CAN'T POST IMAGES because I'm a new user. :/
It's on imgur, with /a/Murqy extension after .com. Album of three images.
Messaging shortcut thingy on the second screen is a lock-screen burn in, as is lock screen in the middle of the first screen.
Sorry for the garbage quality screens, I don't have any other spare phone except for the ancient Sony Ericsson with me atm.
At first this obviously looks like some display issue or a burn-in. I've checked the display, it has absolutely no scratches.
I've also read about the quality issues of some S4 phones and glass+display being glued together which can lead to yellowish tint. And how display breaks easily because of bad build quality and too much pressure being put on the display itself.
Anyhow, ever since that brown/yellow thing appeared the right/left lock screen shortcut animations stopped showing. And that thing is the exact size of the lock screen shortcut animation.
Also, those three burned in lock screen buttons, phone/unlock/messaging aren't really burn ins. When I try to press any of them in the bugged state when the screen is already unlocked, the dropdown menu activates. Also when I use dropdown menu myself, those 3 buttons are instantly gone without leaving a trace. And when the dropdown menu is activated, the yellowish corner translates from the background to the menu itself. Icons on the home screen in the background aren't yellow anymore, but icons in the dropdown menu are.
So, I'm completely at loss what to do here. I don't wanna use one of those burn in removal apps to mess my phone up, I don't have a warranty because I got it used like less than a month ago and everything was working fine. And I don't wanna take it to a repair shop because they'll just tell me the display is messed up.
There's just too much coincidence here for me to believe it's a classic case of display burn in.
Why wouldn't lock screen shortcut animations show up anymore if that was the case? Even on the left side which is completely fine. And it just appeared out of nowhere when I used one of those shortcuts. As if animation is stuck in there.
Sorry for the wall of text, but wanted to explain it in detail as I couldn't find anything similar anywhere else. <.<

I'm not familiar with burn-ins, but since it's a used phone the probability of the screen being messed up is high.
If it really is a software glitch, the only option would be to flash a different rom. If it continues, flash a stock rom via Odin. If the problem still persists, then it's most probably a hardware issue.
Remember, the flashes have to be clean flashes. As clean as possible. Dirty flashes won't help, especially when trying to find the root of a problem.
I've had it for nearly a month now and I didn't have a single issue.
As I've said, it's probably not a burn in because it just appeared like that due to one animation.
And since it's also there when I boot into recovery I don't think flashing a new ROM would help.

Is this gradient (around the icon) visible to naked eye? This is really nasty Just a guesswork: this could be one of failure modes for amoled. I have 8 weird rectangles burned in over the whole screen and really don't know where they came from.
Check this: http://forum.xda-developers.com/showthread.php?t=2603039 evidently even light from outside can burn in your screen.

Yea, it's visible.
That's the far right shortcut on the dock.
But the weird thing is that it just disappears if I try to click it.
Same goes for the lock screen shortcuts as I've said already, that's why I'm not sure it's a regular case of screen burn.
And when I pull down the dropdown menu, the color of the desktop goes back to normal, but dropdown menu icons in the bottom right turn yellowish, as if the tint translated to the screen that's being used at that moment.
After I realized that I tried to mess around with color saturation and brightness.
Changing brightness had no effect, lowering it would just make that corner darker, but as I dropped down color saturation on all of the RGB components more and more it became less and less noticable.
But the buggy lock screen shortcuts still puzzle me. They remain on the desktop after I unlock the phone, but are instantly gone as soon as I click them.
If it wasn't for that, I'd be pretty sure the screen broke because of bad build quality. I read about the display having too much pressure put on it, somewhat of a design flaw.
Gonna try that burn in app, what's the worst thing that could happen to a broken display. <.<

Does it disappear if you press and hold without actually doing something? Make a screenshot and display the image fullscreen as if it was lockscreen, will it happen again? While showing the screenshot, press and hold on the icon, any change?
Does all of the gradient disappear or just the icon burn in?

If I hold it, it actually works (eg taking me to messages or phone menu as if the screen was locked). It doesn't appear on screenshot, only after I unlock the phone. That's what's puzzling me, it's not actually burned in, it looks like an issue with the display when I change screens (from locked to unlocked or switching from desktop to broswer like in that screenshot with the burned in icon, as soon as I click it it also disappears, same as shortcuts).
And gradient gradually disappears as I lower the color saturation. Disappears fully at around 30% for all RGB components. But brightness is way too low then.

I know, I just wanted you to make your phone display the same content as if it was locked - but now the image would be screenshot and not the actual lockscreen... I know this sounds really wild, but I don't see any better troubleshooting ideas here

I get your point, like I'm leaning towards display issue but not a classic one but a weird one because it has issues with switching screens.
Idk, I'm gonna roll with this for a couple more days, if it gets worse it's definitely the display.

Maybe tomorrow if I find a half-decent camera.
Actually, I made a screencast.
https://media.giphy.com/media/3oGRFj88fgqgT3vWrS/giphy.gif
As you can see, after I unlock the screen, all three shortcuts are burned in.
When I press the burned in unlock icon it just briefly opens the dropdown menu (it wasn't me opening it at that point, when I clicked the lock screen icon in the middle)
Yellow tint in the bottom can't be seen on the video.
