    I am running Android on my Udoo in combination with the 7" LVDS.
    The problem is that the left side of the lcd is not recognising any touch input. the active touch area ends 1cm before the actual lcd's end.

    sys/module/usbtouchscreen/parameters/calibration output is the following

    Code:
    818,21,-1620131,12,481,-1100380,65536,800,480
    
    can someone confirm these values? or is there another way to adjust the touch-sensitve area?


    thanks!

    I noticed the same. The biggest problem is that i couldn't trash icons from the dashboard cos i couldn't reach the "X" on the left.
    Anyway now i am using Nova Launcher that is much better than the stock launcher and i can remove icons too :D

    Found something else about this.
    I needed to "touch" some buttons on the left side of the screen inside an app, so i plugged in a usb mouse and it worked as expected.
    Then I just found out a strange behavior: if you move the cursor all to the right or bottom side, it will be "squeezed".
    The same happens if you enable the option "show touches" under Developer Options and then you touch the screen on right and bottom. You'll see a squeezed glowing ellipse instead a circle.

    Maybe this can help you to find out what's wrong?

    Mine has been replaced... and it works now! So it's an hardware problem.
    Try opening a support ticket explaining the issue and i think they will send you a replacement.
