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?

Just got my unit today and love it.
Only notice a soft sparkle (like when you splash water on any LCD screen) but it's very soft and only noticeable at certain angle.
quick call to friend who has HD2, same problem.
anyone else have that problem ?
it is not a problem, it's how this capacitive display is built. at certain angle You will also notice a grid of lines and tiny dots.

It sounds to me like you've noticed the grid in the screen. This is part of the capacitive screen design, and not a fault or issue. It's there on everyone's phone, but as you've obviously seen, it's so unnoticable normally that you just forget about it.
Is it that, or something else?
Edit:
Or you could you read the post above
just curious, how come I didn't notice it on iphone ? lower screen resolution + smaller screen ?

I couldn't say why you didn't notice it, but it is there.
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 have broken my screen (touch amoled, all the screen) and i bought another one from ebay
looks original and arrived in a samsung service pack box
this new display have something strange in colors when the backlight is low, looks like...don't know how to explain but the colors are not perfect as they were with the factory screen...somehow a little bit green (always when light is low)
anyway sometimes now, like one time every week, after i while i'm using it, the screen go crazy and when i touch it, i see (developer, show touch dots) random touch around my fingers
some days ago this problem happened when i was in a call, me and my interlocutor, we heard a strange noise like bzzzzzrbrbzbrbrbzzzz when i was touching the screen, so there was the touch crazy problem and some strange noise when i was touching the screen
a reboot and everything is ok for some day....
i hope you had understood my poor english
opinions? what can i do? :crying:
ps. i have a 9506
It's probably a fake screen. That would explain your color problem and touch problem.

the screen resolution is correct and with high backlight the colors are perfect, looks like original on the front and on the back
how to check if it's fake?
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,
My realme 2 pro device has touch lag on both sides of screen, succesive touch never respond on side of the panel, even after changing the display of the device, i also have made a video showing the same, but don't know where to post it and how to get resolution
