CM11 works fantastic on my D800, just miss the avoid edge touching function on the factory rom. Sometimes I try to reach the far left upper corner and my palm touch the near screen edge, and it is recognized as a multitouch Anyone inform me how to flash this function into CM rom?

I am having trouble with the touch input on an AT&T Galaxy S4 i337 LCD. The phone had minor water damage and the LCD was struggling to turn on all the way. After soaking the LCD assembly in an ultrasonic cleaner for 15 minutes the screen fully loaded and displayed correctly.
However all but the top quarter inch of the screen is recognizing touch input. I have tried the LCD with a known working motherboard and get the same result. When I go into the test mode by pressing *#0*# every part of the screen responds correctly, except the very top portion. When I swipe across the top the line is drawn 1/4" down.
Link to a screenshot of the test.
Otherwise the screen works wonderfully, displays correctly (including the top 1/4"), dims correctly, and accepts touch input everywhere else.
I tried running it through another ultrasonic bath, but I am still having the same problem.
I also flashed the same stock ROM it was already on in Odin. I337UCUAMDL_I337ATTAMDL_I337UCUAMDL_HOME.tar
Does anyone know what could be the cause of the digitizer not recognizing just the very top portion of the screen? It is like the phone has just a slightly shorter resolution according to the digitizer.
So I've been getting ghost or phantom touches on my phone for the past few weeks. I couldn't figure out what was causing it because I've never dropped my phone and it never got wet. The phantom touches only appears down the right side of the screen in almost a straight line. It doesn't happen all the time and I thought it was random but I got it to occur at a successful rate. If I press down on the top left corner of the screen, it would cause the phantom touches. When I press and hold down the top left corner of the phone, everything is fine and no phantom touches appear. I decided to tighten the screws on the top left and it seems to have made it a little better. I'd have to really tap on the top left of the screen to make the phantom touches appear again and it doesn't occur at a 100% rate but it's still occurs.
Anyone know what is causing this? I thought it would be a broken digitizer but it doesn't make sense that tightening the screws would cause the issue to almost fix itself. Problem with the geomangnet? I'm not sure what that does really.

Put 2 (or more) fingers on the screen of your Note 3 in a horizontal line in landscape mode. You can also use Portrait mode with 2 fingers.
Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.

Thank you for the help and suggestion but I've already tried this. My touch screen is fine in terms of detection. I can put 10 fingers on the screen and it would recognize all 10 fingers. My issue has something to do with the top left corner of the screen affecting the right side of the screen. Like something is loose. When I clamp down on the left corner of the phone, everything works fine. No ghost touches (that sounds dirty) or any of the sort. When I let go of the top left corner, I will some times get ghost touches.

It's not a firmware issue. It's definitely a hardware issue since it starts tapping on buttons inside TWRP recovery. Ah well, I tighten the screws even more and it looks like the phantom touches are gone. Hopefully it stays that way even though I destroyed a screw in the process. Those tiny things are fragile.
if the touch ghost click is in some certain location most because of pollution (mainly chemical), best is use ISO alcohol also use a very tinny sharp blade, like a very thin one and slightly go along side the place that does this, sometimes you have to try both horizontal and vertical, then clean with ISO, do a few times it does alright. it does work on most of touch screen include note 3 as well. I've been in IT and fixing all electronic for last 30 years in New Zealand. if you had problem text me on 021 548484
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.
I have a LG G2 D802.
It has never fallen, doesn't have any significant marks of usage but my screen has a kind of row (1 cm) in the middle of the screen, from the left to the right of the phone that does not respond to my fingers.
If I draw a line from up to bottom, there will be a gap right on that "line".
Is there a way to see if this is something related to software?
Is this solvable with a new kernel?
Is this a real problem that will require a new touch screen?
Hello, I noticed that when typing with my right hand, I can't seem to use the keys on the left edge of the screen such as number 1 on Samsung keyboard for instance. It works some times but mostly not and when trying over and over it registers 2 out of 10 times. I'm not sure it is a sensitivity problem as with my left hand, number 1 works always. It seems that the edge of the screen works best when approached by the hand on the same side as if it works under a certain angle or so, anybody noticed this? I tried swiftkey and it is the same. Thanks
Somehow this thread got lost in the Q&A section?
Edit: Sorry, it looks like the search in the browser was not working properly.
So I went to Samsung store to test other S7 edge devices and they are all the same. The guy there mentioned that somebody else has complained about it earlier. It seems that when trying my hand slightly touches the edge and this stops the phone from recognising the touch on the other edge, weird.
I think what is happening is palm rejection by the right hand. You can resize the keyboard in settings or try Swift key

1010110101010101. Guess that's not an issue for me with the keyboard, but there have been other apps that made me wonder if my touches on the side were registering.
