I have a ZT-180 tablet, not sure if it is V1 or 2, it has the camera and hdmi output. It is a 512mb ram, 4gb flash hd, 1ghz processor, running Android_2.2. I can be playing an app and it will kill it and kick back to the home screen for no apparent reason. It does this mainly when playing Angry Birds, Angry Birds RIO, and some other games. It has also done this when in Browser and attempting to open a web site. Has anyone else had this problem or any know of a fix for it? I have not tried to flash the whole tablet yet, I have only had it a couple weeks.
