Hi..
I have installed a new 7" Chinese car Android player in my car. From day 1 it's touch panel randomly stops working then started working. The player keeps on functioning i can use a mouse to interact. Most often it happens at the first 5 min of starting the car and after 10 - 15 min it starts to work and keeps on working. Sometime it works and keeps on working.
When the touch panel hangs resetting the player with a pin doesn't do anything, Android reboots but no touch then after some time it starts to work.
The touch panel is using GT911 6pin connection which i read uses i2c bus.
So far i cleaned the connection in mother board, insulated the flex cable of digitizer, added another ground cable to the player.
But still same random hang.
Please help.
Thank you.
