I know this is an old thread but it seemed like an appropriate one to use. I have a similar problem in that the digitiser is broken on a cheap Chinese 7 inch tablet running ice cream sandwich. It works with mouse fine so I tried disconnecting the touch screen. Unfortunately, pulling the connector leaves all the capacitive inputs floating which means thousands of random perceived touches all over the screen at once. I have the device in USB debugging mode so can see the touches everywhere. I've plugged the touch panel back in and managed to pinch the top right hand corner of the display enough to make it semi usable while I use the mouse and navigate through the menus etc. but this is no real fix. I'm keen to pull the touch panel off altogether and was wondering if there is a way to disable touch using USB debugging. I know little about ADB and SDK but am happy to follow my nose. I saw a post on another forum that showed a way to do it through a command line but don't know if the commands are device specific or not...
All the info I have on the device can be found here:
The link was provided by the person who gave the tablet to me. (After he had broken it)
Any help on this thread or advice on where to find the answer on this forum or indeed where I should create a new thread if suitable would be greatly appreciated.
