Hi everyone, first post and it's about a G1 I recently purchased.
My phone is using the Cyanogen Mod 6.0.0-DS, which is freshly installed. The weird thing is that about 2/3 of my screen (when in portrait mode) is unresponsive when I place my finger on it.
When I touch in the Left 1/3 of the screen, it recognizes my touch and works. The even weirder part is that when I start my touch in the 1/3 and move into the other area of the screen, the phone recognizes my movement.
So say I'm on the home screen and swipe left to right. The screen recognizes my touch and I can hold down the touch into the right side of the screen and it follows my movements perfectly. It's only when I touch in that 2/3 right part of the screen when it touches not recognize the touch.
Now, my question is this: Is it software related or hardware related? Is there a setting I can use to maybe calibrate the screen. OR do I need to replace the screen (or digitizer? can someone help me understand the difference)?
Thanks in advance for reading. Any help is greatly appreciated. Ask questions if need be

I am having this issue, too. Anyone able to help?
Its common, I had couple of phones with intermediate touch issues on a portion of the screen, a new digitizer took care of that.
I am not sure whether it is my mind playing trick with me or not, but I feel like my phone is less sensitive after I did the hard reset (power+volume down). Sometimes I need to press 2-3 times because the first light tap was not detected.
So is there anyway to increase the sensitivity?
I have the same problem, but no idea that is the hardware or only software problem.....
Fresh owner of this Optimus 2X in France, in our community, frandroid.com, we encounter the same problem , I think this is a software issue.
Did someone already contact LG??
Maybe they should include this into the bug list thread.
May I know were you guys having this problem since it is out of the box? or after reset?
I have the same problem started from day 1 till now
I have the same issue and already thought I'd be the only one having this problem.
I would not say it's a problem with sensitivity, but it feels like the touchscreen goes into some kind of sleepmode where then you need to press a second time, to wake it up.
Continuous touching is no problem. (like when typing rapidly on the keyboard)
This video is not from me, but it shows the problem.
Have a look at 13:28 and 13:37. The reviewer tries to hit the "Ackermann" entry, but the touchscreen does not recognize the touch. At 13:37 the guy has to press another time to get the entry selected.

Yes! The touchscreen is definitely less sensitive than my old HTC Hero, and gets quite frustrating sometimes when a scroll misses the first part of the movement or a click is missed.

just in case, are you guys using 20110218 baseband too?
The same problem here. If I unlock the screen and then tap on any on screen apps, I need to touch again for it to open. Only the first time though, after that it function ok. I think this is a bug and needs to be fixed... I have my pc for double-click.
Yep, count me in. Same problem here. Sometimes screen taps aren't registered. Will do some research later on, but I think it's a software problem. (maybe you have to tap 2x as fast )
Hi,
same problem here!
Potentially a driver issue. A Nexus S user had a similar issue in this thread: http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/
He managed to tweak the driver and it works fine now. Need to know C++ (I think?) to understand though.

I see, then probably they will fix it on the next update/gingerbread?
Same issue here.
Correct me if I'm wrong, but the problem seems to be that the screen has zero tolerance when it comes to tapping and swiping together. If you tap and slide your finger a bit directly after the tap, the tap is ignored. In other words your tap has to be a steady tap when you click on a button or an app. Right on the spot and with no swiping or sliding afterwards. I can't reproduce this on any of my other devices.
Ergo, it seems that the natural tapping I'm used to isn't working on the x2. It seems like I have to adjust my tap. I think that this could in principle be solved with a setting somewhere, because clearly the x2 is capable of registering this in for example a web page.
The great thing of this is that you can safely tap and swipe in the app drawer to scroll up and down or left and right. The downside is that a tap with a little swipe isn't registered at all. I would say that LG has choosen here for a wrong setting.
My personal experience about screen sensivity.. can you confirm if it's the same for your device?
I noticed a strange touch response.. and after some tests, I can say that the touch screen and icons are influenced by the surface where the phone was put!
with the phone in my hands, it's all ok (only sometimes - rare - I need to tap more than once).
If I put the phone over a glass surface (like a glass table) without touching it with both hands, the touch and the icons not respond!! NEVER!
If I put the phone on my scanner the touch screen works ok, but the icons not (or only few and rare taps was detected).!
If I put the phone over my big Onkyo amplifier.. It works like in my hands.. or better!! even without touching with hands.. only with a finger!
Put it back on my glass table.. and all stop working again. If I put a aluminium foil under the phone (between phone and table).. the touch and the icons works again !!
If I put it on the bed.. it don't work.
LG support say that they have tested the phone about this issue after my report.. but no strange response was detected by them. I don't know if they really tested it..
Try it and let me know what you think about!
tested on glass surface, I can press and swipe through pages with a finger without problem.
it is true that my device is not so responsive, but aint reaching that level yet
i read about a similar behaviour on other devices because some devices need a proper grounding for the capacitive screen to work correctly. You can find this problem via google.
Some devices have problem in a car-mounting, for example.
But i think thats not the problem the thread-opener talked about?
Guys I'm looking to get this phone and after reading Engadgets review of the X2 where they mention that the screen is not as sensitive to the touch as other phones I got a bit worried and started googling which lead me here!
Is this true? The screen isn't very sensitive and you have to apply more pressure than other capacitive phones?
I know that the OP is talking about a different issue but I reckon LG will get that sorted out via software update, or at least hope so!
Please do post your experience about the screen sensitivity of the X2 as this is putting me off. I currently have the Motorola Milestone 2 which is very sensitive to the touch even with a screen protector on it.
Cheers
My HTC 7 MOZART phone has a problem, when to unlock the phone I Swipe my finger up to unlock the screen or answer an incoming call... the screen doesnot go away easily...even I press on the botton and swipe up.
There are several threads on this topic already:

Some people believe it's a hardware problem and other suggested software workarounds. I have replaced digitizer on my phone and it started happening. Then I realized the digitizer cable has an area that is supposed to touch the LCD screen (grounding probably?). I fixed the connection and never witnessed the problem again.
Update: It started happening again, albeit much less than before. I tried the "mwang's fix" referenced in http://forum.xda-developers.com/showthread.php?p=20105772#post20105772 and now the lock screen feels even more responsive than with the original HTC digitizer.

It was very helpfull... thank you!
I recently bought a Xperia SP C5302.
Within 2 days, the top part of the screen stopped responding back.
Initially it used to work after locking the screen and then unlocking it but now it doesnt even responds on rebooting the phone.
What should I do now?
common problem

It is a common problem found in many SP phones. I went to purchase a black SP and it had the same problem. I checked there itself and changed it with white SP. It is not the problem of navigation bar. Navigation bar will work when you rotate the screen. The problem is with the touch screen. You can check this by enabling 'show touches'. My suggestion is to change the phone.

The thing is its been a week and the dealer wont change now.
I have checked the touch using its service menu and it shows that the top 1-1.5 cm touch isn't responding.
Shall i take it to the service center?

Yeah. As it is just one week old, take it to the service center.
Hi,
so I have a huge problem regarding my HTC ONE it's touch screen and capacitive buttons
some times touch and buttons work and sometimes it's not but mostly not
when I press hardly on the bottom of the screen near the home button it response shortly then return back to not working
When it suddenly works and the touch moves smoothly the phone vibrates just like if someone presses the screen and buttons and it returns to home or keep pressing in such a mad way
I couldn't figure out if it's software problem or hardware problem
and I seek help
I think that this touch screen touch problem is mainly because of capacitive touch problem
note:
the phone did face some hard actions, it falls from my hand in the ground few days ago but there wasn't any problem at the time
I have seen problems like this caused by electrical interference (using the phone too close to medical equipment), and by chargers (electronic interference from input current that's not "clean"). In your case, I would guess it's hardware damage. Have you upgraded the OS while keeping very old firmware (drivers)?

If you upgraded officially, the driver update was included in that.

I think it's broken. If a factory reset doesn't solve this, it needs warranty service or a new digitizer (cheaper than the LCD panel, if they can be replaced separately).

If a factory reset didn't solve the problem do you think that installing custom ROM would solve the problem ?!?!?!
could I replace the touch screen only ?! or should I replace the whole LCD with touch, since the LCD doesn't really have any problem
I though of installing custom ROM and try to disable capacitive button and see if the touch problems with the screen goes off
I feel like that since when I press hardly on the right bottom of the screen solve the problem momently maybe it's an out of place lcd or touch thing since it fall from my hind before !!
