Touch screen not work with right bottom conner

I dont know why but today i use quick memo and realize that have a small square at right bottom conner cant be touched. I clean my screen, remove the screen protector but the problem didnt solved.
It is the bug off ics xbsall v7 or my touch screen is bad? Could any one have a test please?

would assume your touchscreen is broken. i had the same issue some time ago and the only way to fix it was to have it repaired at lg.

I have faced this problem some time ago with another phone. I just replace screen protector and have a cleaning the screen surface to solve problem. But this time with our fuc...king phone I have no luck. :crying: In my place it take about 100usd to replace the touch screen with the new one. :crying:

I realize that my dead screen touch conner will work well if i hold a finger on some where on the screen and have another finger touch to the dead conner. So with this test i can surely that the hard ware still work. May be the problem is the ics driver. Im on xbsall ics v7.2

Go to settings , developer options and select show touches , then slide towards the section of the touchscreen that doesn't work and see if you see the lines going over that spot.
If not , flash a different ROM then try again.
If it's still not working , then your touchscreen is probably broken.
You can buy replacements off eBay for 19 dollars , free shipping.
This question has been asked a thousand times , next time do a search before opening a thread.

Ive already use the developer options to see the spot line off my touch on the screen. I mean that with only one finger touch on screen so the dead corner didnt realize my touch. But if I keep one finger on screen and another finger make a touch to the dead corner and The dead corner touch is working (with dual touch the dead corner become working but singer touch).

yesterday i faced the same problem, when i : 1 ) disabled some google apps from application minue
2) uninstaling dx toolbox which i placed its shortcut on toolbal
when i uninstalled the app the shortcut was gone and left an empty place , i wasnt able to use my bottom right corner on the toolbar also on the screen.
i managed to fix it by enabling those google apps that i already disabled
sorry for my bad English

my rom is 30a i didnot use the flash method i used KDZ version.
i made a dual touch and the hard ware is working very good.
like i sade i managed to fix it by enabling the some google apps that i had disabled for battery improvment.
i think you can fix your lg phone by offline updating with KDZ version.not custom roms.
i think your problem is software related not hardware as long as your hard ware is working.
well this is my opinion i hope your phone will be fixed

So your problem is singer touch to the bottom right corner not working but dual touch with 1 touch to the dead corner working well? May be i will try to flash a stock bin file when i have time.

well, when i had this problem i didn't know that there is an option in developers minue to test the tuch area, but after fixing it , i came to this xda site and i saw your post.
that you can touch the dead corner with dual touch
as a noob i suggest that you use fresh kdz instead of fls/bin, using kdz is the best method , it will make your phone as fresh / new as before.
good luck buddy :good:

What I need to do is set the pixals required to move to 0!!!!!!
Do you know of something that can do that for the tab 2?

Well try to install any calibrate apps and wee will see..

touch delay
Hello i have this problem too in my G tab 2, its more like a dead zone because you need some space for the touch to be registered, its very annoying because i cant aim precise on games, and can you give me an example of a calibration software

I think i got it
I think i found a way to fix this, it's an app called "TouchScreenTune" it needs a rooted device, i didnt try it since my Tab is not rooted but i will try it soon, so when u open it just change the first slider "minimum Movement amount" to 0"most left part" and tap apply and see in the upper part of it works

[Q] Band of touch screen not responding

Hi, I have a problem with the touch screen of the Nexus: a few days ago I realized that a central band of the screen, more or less half an inch high, no longer responds to touch ... To understand, I attach a picture made ​​with 'Position pointer ' from 'Developer options'.
I wonder if anyone has ever had experiences like this, and what do you advise me to do,namely if trying to change the screen, or maybe other most basic solutions (I've read on the web of people who recommend 'squeeze' the screen). Unfortunately the warranty has expired three months ago ...
Thanks in advance

Had the exact same problem with my old android phone, it was after a great fall... I assume that it is a hardware problem and you have to replace your touchscreen to fix it...
But its not a big deal as you dont use that part most of the time and also "auto-rotate" is always present to help you... And if still you cant touch some things then use VNC viewer...

I do not know if it can be somehow help .. The page is in Italian, use google translate .. It is said to 'squeeze' the screen, many people seem to have solved .. Do you say that is our case?

[Q] Strange screen behaviors

Seems like something might be wrong with my phone. Today out of nowhere I started to get strange lines going through the screen for not even a second, similar to how a broken LCD will show multiple colors.
A little bit ago Netflix froze up and, I locked the screen it it should the top half on the bottom and the bottom half on top for couple seconds then went back.
I've done nothing to damage the phone, but it seems like the LCD is messing up on it, and I really hope there's some solution...
Any help appreciated. Thanks.

you are undervolting?

No, but I am on ElementalX kernel. I rebooted my phone and it stopped so maybe it was a weird software issue. Hopefully that's it.

maybe it was a derp. if it happens again, try another kernel. if it still happens again. its not elementalx.

[Q] Touchscreen issue?

Hello! Sorry if my English is not great, it's not my first language.
I have a Prestigio 3400 Duo and I have two issues with my touchscreen, the multitouch function in particular. My phone is freshly factory reset, done while trying to solve this problem, and
The first problem is pretty apparent, when I'm holding two fingers on the screen in a horizontal line it registers only one point at the center of the two I'm actually pressing (that's what a multitouch test app sees, at least). This happens exclusively in an horizontal line.
The second problem I have is when I'm holding two fingers on the screen and I let one go, the other one - the one that's still holding - is not getting registered for an instant before appearing again. So when, say, I'm playing a game on the phone and my character walks and I press a button at the same time, the character stops for a second. Really annoying stuff.
Is there any solution for either of these? I saw some fix for other phones but they're exclusively for those, not mine.

Well I don't know if it was something that I've done that caused this, I don't play many games so I've noticed it only recently. I can tell you that for a while the phone was rooted - now it isn't - but I've never installed CFWs or stuff like that.

I took off the root thing because I wanted to play a game that doesn't accept rooted phones.

Can you direct me to a good custom rom or how to reinstall stock? I'm not good at these things, I don't know much about it.

Thank you, but there's no stock rom or a tutorial there, so...

I'm bumping the thread, hoping that someone that knows how to fix the problem can see this.
I'd like to at least solve the second problem, because the first one is barely noticeable to me. I basically can't play any game with the second issue because it's really annoying. I read that sometimes these kinds of problems are when you have an app that is used to block the touchscreen of the phone, but I've never used any of those so I don't know.
