[Q] Is anyone has bug of the touchscreen? - LG Optimus 3D

After lock the screen of my o3d and wake it up, the touch panel is very unstable. By using some multi-touch testing app, it can found that the touch panel can only recognize one finger accurately. It there anyone know how to fix this bug????

i did not notice this problem. Try wipe. What firmware you use??

Try to install Android system info. Tap on menu, and touchscreen test. There should be ok.
For me in some testing apps from market, there where some anomalies. Eg. Taping both fingers very fast, and then it recognized only one touch etc.

Seems to happen to me as well on stock 10J Optus Australia firmware. The touch screen seems to be able to detect >10 fingers (Most other smartphones are 3-5) but when more than one is used, the touch points seem to jump to the other finger (For example, in fruit ninja, when two fingers slide vertically quickly, sometimes a random horizontal cut occurs).
Its pretty annoying in games - Especially when trying to shoot and aim in Modern Combat 2, I keep doing 180 degree turns randomly.

Yes I have the same problem in games, sudden180 degree spins in backstab, shadowgun ...
I'm on stock GB.

happens almost everytime screen locks when a game is running. try playing minisquadron and let the screen lock. when you wake phone up only one touch will be recognised at a time for an interval ranging from a few seconds till you shut down the game and restart it or even sometimes restart your phone. had it since v10a all the way to v20a and believe my i tried them all. even on custom roms....

The solution: (kind of)

I thought I was just crazy when this happened.
The 3-tap fix doesn't seem to completely fix it but it helps without having to restart the game.

[Q] Weird screen issue on the 7.0

Hi guys,
I am having a weird issue on my Galaxy Tab 2 7.0 where, if you hold in one spot for too long, the tablet stops detecting your finger on the screen. This is most apparent in games where, for example, you have to hold one direction on a d-pad for a while. After holding the button for 5-10 seconds, input is no longer detected, and the character stops moving. At this point, I'll need to remove my finger before input will be detected again (and this can take anywhere between instantly to a few seconds).
I've tried it on 4 tablets and all present with the same issue. Does anyone have any solutions/suggestions?
Yes am too facing this issue but still no fix found...
Its called water drop detection which means if u long press screen your touch get disabled for 2-3 seconds...this"FEATURE" is for avoiding accidental touches....i hate it....gives a lot problem in games gta,where is my water,moto racer etc...

issue with touch screen

The main issue I'm having is, on occasion, the touch screen seems to behave erratically, registering input even when I am not touching the screen. I can't seem to figure out how to reproduce it reliably, but it seems to happen at least once every day. The phone seems to think something is touching parts of the screen, as it launches apps, types garbage on the keyboard, bounces the lock screen up and down, etc, all without me even touching the device. And of course, when I do touch the device, it either doesn't register, or 'fights' with the ghost input, and basically doesn't do what I want.
Try changing your touch sensitivity from High to Normal. Find under Settings - touch - Touch sensitivity.
This worked for me Mine was very sensitive too when I first bought it but after messing around with it for a couple of days and changing the setting from High to Normal and back again it's been fine ever since, Crazy!

[Q] Anyone else have an unresponsive touch screen, especially in games?

I first noticed this on a running game where you have to hold down either the left or right side of the screen to move in that direction. It would usually register the first press, but not that I had held my finger down so I wasnt moving properly. I thought this was due to the game it's self rather than my phone.
I've just downloaded Naugh where you have to rotate the screen by touching either side of the phone, and again the same issue. It's really unresponsive - It will recognise the tap but not that i've held it, it will stop working. Occasionaly this will also happen when scrolling a page.
Has anyone else experienced this? Or if not, any suggestions on figuring out whats wrong?

When you go to Settings>About phone - there is a Diagnostics section>Test device. You will see a list of tests you could do including touch screen.
I've tried this, thanks.
There is no aparrent issue using this diagnostic. It doesnt detect multi-touch though, which I find a little odd.
I did find this article though:
http://johnhaller.com/blog/2014-03-06--sony-xperia-z1-z1s-touch-screen-issue
Which seems to be the exact same issue I have on my Z3 now.

What do you mean? There are two options; one which shows dots where you are touching, and another which shows two lines for each point you touch; the lines cross at the point you are touching. They absolutely do detect multitouch, so if you're using more than 1 finger but only seeing one point, or one pair of lines, then you have a problem.
I only have one option under that test, which is to see a yelow line. It doesnt detect more than one touch at a time though.
I have downloaded a seperate screen testing app, and that detects up to ten points at once - again without any obvious issues with unresponsive.
I really can only reliably replicate the issue when playing games.
Mine does have a similarish issue.
Double tap doesn't work on first try when you last use the phone for some time.
But i think it is a software thing cause it worked fine when in continuous use.

In Settings, enable the Developer Options, then tick "show touches" and "pointer location".
I notice this issue all of the time in Ingress, however I have tried multi touch test apps and can easily get perfect tracking with 5 fingers on the screen, so I am sure the multitouch and display is working fine, and I have no problems with Google Maps or Waze where similar gestures to tap on things, and two fingers to rotate and shrink/enlarge are used.
I have no idea what is causing it, but it seems to be software rather than hardware.

I don't play games on the phone, but did try Modern Combat 3/4, which I have purchased long time ago, just to try them out. So I have played last night and have not had touch screen issues.
Yes I have noticed it, and it has at times been extremely frustrating, and 99% of the time I think part of my fingers holding the phone are touching the screen somewhere, each time I see this and adjust my grip the problem is not longer there. I think this also is partly related to the thread about ghost touches.

Yes exactly the same issue.
I agree I think it's software. Another strange thing is If I flip the phone around (So the headphone jack is now on the right, rather the left), and the game allows the screen to rotate, the issue goes away completely.
Such a strange bug.
Same thing here, and it happens very often. I ran all tests and it seems a software issue. Hope Sony solves it 'coz it's damn annoying.
Just discovered something else, in Ingress, it's always been dodgy with multitouch, however if I put the phone on the table or sofa and just touch the screen it's even worse.
Again using the same gestures in Google Maps it works fine.
I don't understand why not holding the phone would make a difference. I tried propping it up on the table to see if it was related to the angle, but still a lot worse when not holding it compared to holding it.
Never had it during games but during calls it kinda doesn't respond to touches properly.....weird.
I am facing too many issues with the Z3. First the camera quality, then the front bezel leaking light, then the 3G, now touch response. Duh!!! Should've bought the HTC M8 EYE.
No such issue for me so far at least.
Isn't the M8 Eye for China only?
I can't type for **** on my Z3 compared to my SIII. Taps don't register as quickly. Not sure what the heck is going on.
I can confirm that the latest firmware 23.0.1.A.5.73 released by Sony today, has fixed my issues with the responsiveness with the screen and games.
I hope I see that update soon. I can't wait to type quickly and double tap with no issues.
No issue with games but, typing is a chore, it keeps pressing the wrong keys like b for spacebar etc....

I've been noticing this lately as well when using the phone when it's on a flat surface.
Sometimes pulling the notification bar down can take a few times.
While play Ruzzle, it's nearly impossible to spell a word unless you pick the phone up.
Was thinking it might be the way it detects your finger, as I normally use the tip of my finger when it's flat, and my thumb when it's in my hand.

sometimes unresponsive touch

So, i have Mi4W for almost 2 years, and now it's touchscreen starting to become unresponsive. Is there something i can do myself about it (without bringing it to service center)?
The problem is minor and only happen sometimes, though mostly when i use it for rhythm game where i need to do fast multiple tap or hold tap. I've tried wiping the screen clean but the problem still there.
