my telclast x98 air 3g also reboots randomly.. but seems related to one app from what i can see and since
the app was updated recently.
however I think I had weird problems with last years FB (facebook) update.. it started to hang device or slow it down
I removed FB and the tablet was heaps better and stable until this new problem has shown up. suspect its coding and video card conflict.
so did the problem show up recently or always for you. try removing FB and see if it becomes stable.
I also suspect they suffer from heat.. is tablet in a case? someone added heat pads and more copper inside theirs and solved heat issues and lock ups
