[HELP] onda vi10 - cyanogenmod10 - touch screen problem

Hello guys,
I try neoficial Cyanogenmod 10 http://forum.xda-developers.com/showthread.php?t=1821398 with my Tablet OndaVi10 v2.
Tablet crash and I had to use Livesuit and install any firmware. I do not know if the correct version.
From the second tablet (same type-original without modifications) I did that backup (use ClockworkMod recovery) and recorded this backup to crash tablet.
Tablet running ok now, BUT I have a big problem with touch screen.
Touch screen senses the bad touch (in a horizontal position). I tap on the upper edge of the display, touch screen but it reacts in the lower edge of the display. In vertical position it works properly.
Where is a problem? Any idea how it fix? Another firmware?
Help me, please Thanks!

[Q] Phantom Input

I am having issues with my Verizon Galaxy S3 SCH-I353. Over the past few months this problem has been increasing in severity. My screen is detecting "phantom inputs". These inputs are rapid, horizontal movements in the top 1/3 of the screen. These movements render the screen unresponsive, and will register as touches to any screen item in that zone. Turning the screen on and then off stops the movements but only very temporarily. Some days this problem is minimal, while others my phone is nearly impossible to use due to the frequency of these inputs. These inputs occur in the same exact spot every time, and at the same spot that other people have reported, so I can rule out screen scratches or smudges. I created a .gif of the inputs after I turned on "show touch inputs" in the developer options.
I've seen others with this problem online, but no one has narrowed down if this is a software or hardware malfunction. Here are some of my possible problems:
1. Hardware: Possibly a loose cable? Malfunctioning Screen? Possible fix - taking it apart and putting it back together.
2. Software: Screen needs re-calibration of some kind (too sensetive?), would this be possible?
3. App running in the background that overrides touch inputs and is somehow creating this?
Any help would be greatly appreciated.
Other info: Problem started on stock 4.1.2, Verizon SCH-1535
Now on stock 4.3, rooted with xposed modules.
Phone was purchased new in Fall 2012.
No water damage.

[Q] Resistive screen offset problem after replace

I've replaced the resistive screen of an Huawei U8110. I've checked it is working properly entering with adb shell and then 'cat /dev/input/event0' (this is always the screen), and it returns raw data wherever I touch the screen.
The problem is that, with any rom I tested, the screen is displaced about 1cm to the right, so I'm even unable to unlock it! Because of that I'm assuming that the screen calibration is recorded directly in the touch detection chip, so my questions are:
Is it possible to know the chip brand and try to communicate with ti directly to do some kind of "reset calibration"?
Does somebody know if there is any rom with ts_lib integrated, so there'll be an extra layer that enable the user to calibrate de screen in software?

[Completed] [Q] Touch screen calibration issues

Dear sirs/madams.
I have an Intenso Tab814 tablet that has Android 4.1.1 installed. I accidentaly broke my digitizer, so i bought a new one and installed it myself. But i am having issues with the touch input, seems like i am pressing on a specific spot but it is like i am pressing a little further away so it is difficult to use. I am trying to calibrate my touch screen but i am unable to find the calibration menu. How should i procceed?
Sorry about my poor English

[Q] Touch Screen Unresponsive plus White Horizontal lines

Hey guys and gals,
I have nexus 5 that is just about a year and a half old. Every now and then, when I wake up the phone from sleep, the touch screen becomes unresponsive and I see white horizontal lines running across the top. I have tried restarting the phone, resetting the phone to factory. The problem still persists. The only way I get the lines to stop from showing up and get the touch screen responsive again is pushing down on the screen hard at random location.
I have attached a video of the problem I'm getting. https://youtu.be/CzgZ1bcN1Lk
I'm suspecting its a screen issue and I need to replace the LCD panel, Digitizer, etc
Any help would be greatly appreciated.
Thanks!
You need to replace the digitizer (if I'm not wrong), I've encountered this issue before on my older phone.
