Is there any information in the tablet that will tell you when or where the device was made? All I can see is the kernel or OS version. If you know, then maybe we can get an idea of which tablets to avoid buying or which ones have the problem with the screen de-sentitizing. My NEW Nexus 7/2 tablet is only a week old, and already the screen is a little funny. Just after I updated the OS to KOT49H... Don't update your Nexus 7-2 to Android 4.4.2!!
