well my htc hd2 is using android and using it a year by now and notice that the upper left of the screen is not working?is it the lcd or digitizer or just need to align it?i dropped this many times(up to 5 times i think)but no damage on the housing and it looks new,and it is annoying in some games cause it wont work and i notice a very little red dot on that part.....pls help
If you lost sensitivity and the screen does not respond to touch, then it's a digitizer, if picture is distorted or, as you describe, a red dot appeared where it shouldn't be - LCD, sounds like both in your case. I am not quite sure how it doesn't work in games or whether the problem is present in normal screens. Alignment is a procedure to tune and correct mistakes in touch recognition or to make touch more precise on resistive screens.
I suggest replacement of your LCD + DIGITIZER. Dropping it many times may have caused it too, even if housing looks perfect.
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 owned a Xiamoi Mi5 and It had a anoying "touch latency" or "touch sensitivity", that we could notice when you quicly move the finger along the screen and the phone took some extras miliseconds to follow in comparission with other phones. Do the Mi Note 2 have the same issue?
No dude , the touch works perfectly , it's the most touch sensitive phone i've owned till now.
was a while since i was here last time.
Congrats to devs for switchroot, bought switch just to flash there android.
in description of known bugs there is a phantom touches sometimes, thats not actually true. The touch is oversensitive.
i installed pixelstarships and immediately noticed that its not random , its always present
In game if you want to look more the right, you just touch and swipe it to hte direction and your cam moves.
You see, if you want to select something (room / crew..) you just point at it with finger and touch. However this is not the case, cause your finger is detected much sooner and instead of selecting something ,you for split of a second will do "touch and hold" , efectively moving cam around few millimiters. Your finger is ALWAYS detected like 1-2mm above the touch screen (i learned how to touch without touching, it took sometime...)
Hope it will get fixed in next release.

It's already known that the issue with touch is the internal resolution is 1080p. An example of this is the boot screen when Android first starts. 1080p on a 720p display = inaccurate touch.

have no idea of inacurate touch (did not had this issue) , i m talking about that "touch" got detected before the actual touch.
But good to know,
I changed the whole screen (lcd+touch). Then I noticed that the screen touch performance is buggy. I couldt type well, it touches twice and writes a word for example "like => liikee" and this makes me crazy!.
Then I changed it again with a better one but this issue stilles. the response of touch screen is like a low resolution. But when i use a simple drwaing app it draws perfect lines even dots close enough. What should I do to solve this?
