Greetings, using an E975 which recently had to get its screen+digitizer changed, which is working fine except for a little issue, touches get registered about 1-1.5mm lower compared to where I touched. So vertical orientation is a bit off, horizontal appears ok.
Old/original digitizer didn't have such an issue. Rom is official 4.4.2.
I tried pretty extensively for a touch calibration app as well as looked in the menu for a built-in option but no luck. Any ideas?

About 2 months ago I started getting phantom touches on my screen, always on the right side. In the app Dotty, I could create the touches by moving my finger near the right edge until a circle would appear and start barely moving up and down really fast. This would be the primary touch point and other touch points would show on the screen in Dotty but in any other program all secondary touches were ignored(keyboard, homescreen). This created the illusion of the touchscreen simply not working. To fix it I had to sleep/wake the phone a couple times until it went away. This issue would come and go and seem to be really bad for a day then there wouldn't be a problem for a week. As of now, the phantom touch point problem seems to have gone away. However, the right 1/4" of the screen no longer registers touch. This mainly only affects the P key but is quite annoying. The strip that doesn't work runs from x:287-320(edge) in Dotty. I've flashed, re-flashed several roms and can't seem to fix the problem. Any ideas? Is this a digitizer gone bad? Should I contact HTC/is it covered by the warranty?
My touchscreen have some issue but i don't know if its a software or hardware issue.
at start when I use my phone it works perfectly but at time past the touchscreen will press randomly and at a point

press randomly and so on...

Does this happen while you're on charging?

Both, either not charging and charging...
and there's an area in the touchscreen that is untouchable
but when you restart it a couple of times the whole touchscreen will start functioning again...
The touch digitizer might be damaged.. As was in my G too.. To find it out set the brightness to full and check near the bezels.. If you see white light coming near the bezels (the black colour has been somehow scratched away).. Then you need a digitizer replacement

Well, this seems to be software problem if it is specific. Did you try a wipe? Reflashed KDZ?

Did u try to test the touch screen in lg hidden menu .. You can enter it by entering the following in the dialer
3845#*<yourmodel>#
Eg.
3845#*975# for lg e975
3845#*970# for lg e970
In the hidden menu go to device test then individual item test (at the bottom) then. Touch Draw Test..
Now just draw there and see for yourself if the Touch is damaged...
In my case , i couldn't draw at the center of the screen ..

Recently, I've got an issue where the screen will randomly go dark, but not turn off. I have chekced this in a dark room and the screen remains on, but it no longers registers any touch inputs nor displays anything on the screen. The screen remains dark until I turn it off and turn it on again. I tried a screen recording app and checked the video afterwards. It seems that once the physical screen goes dark, the video shows that everything starts to run very slowly. From this, i'm guessing that the issue is either the CPU is having trouble or the GPU can't render the screen properly, although the recording seems to show that the screen is still there, but just not shown on the physical device. I checked the CPU usage though, and it doesn't seem to show issues as it is not running fully with about half of the memory free.
I have tried reflashing the stock rom with this
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
and the probelm persists. This also wiped root access and i have not yet restored it.
Could this be a problem with the CPU/GPU or would it be a physical problem with the hardware of the screen? If the issue is with the
Hello. So recently my phone has behaved verry strange, when I wanted to type the screen went off. After that everything was back to normal when I noticed that the touchscreen at the top of the creenw as not working. I couldn't pull down the statusbar. I changed the android version completely but no change. The exact part where the statusbar is the touchscreen is dead. I downloaded an app with wich I could thest the touch. I uploaded the image so you can see it too. Is there a solution or do I need to change the screen?
Cheapest route is just the digitizer. Easiest route is the lcd and digitizer combo. Takes about 20 min to change first option can take hours and easy to mess up
So I need to change te touchscreen and display? I tought that is just some error that can be fixed without changing the touchscreen and display
Use the 360 screen rotation mod from Fulmics rom or G3 tweaksbox and see if you can pull down the status bar the other way around?.....
Hi everyone.
I have recently had my screen replaced. After playing around, i quickly noticed that my keyboard screws up when i start typing.
The faster i type, the worse the problem is.
I checked touch response times and achieves normal times of about 60ms, however, i turned on touch overlay in developer settings and noticed that if i touch opposite sides of the screen quickly (to simulate typing), it would draw lines between the touches as if i was dragging between the two points.
This is what causes my keyboard to do funky stuff and heavily lag when typing fast.
Please note that this never happened before the screen replacement, and a hard reset didnt fix the problem.
Is there any software fix for this, or do i need another screen?
thanks.

I mainly work on iPhones, but it sounds like your digitizer is out of calibration. Don't know if there's a software fix for it, but hopefully this will point you in the right direction. Also I'd take it back to the place you had it repaired and see if they can fix if it's still warrantied.
