Hi,

I got Pipo Max-M6 Pro.

It had weird behaviour related to touch screen. Some buttons (or areas) were not accessble by touch. I needed to twist tablet in otder to push the button. After upgrading to "[ ROM ] Pipo M6 pro custom root Android 4.2.2 firmware (OTA_1.1.2 - 2013/12/04)" (http://www.arctablet.com/blog/forum/pipo-max-m6/rom-pipo-m6-pro-custom-root-android-4-2-2-firmware-ota_1-1-2-20131204/) Touch screen problem didn't go anywhere. Now I turned on "show touches" option and yeah I see that touches are shown below the place stilo placed. And the closer to top of the screen the bigger difference.

Anyone knows solution of this? There is no calibrtion tool in software found (at least I can't see it anywhere).

It is good tablet but e.g. using keyboard with this un-callibrated screen is pain.

Thank you for any help.
