I am still fooling with this Hannspree HSG1279 tablet running 4.2.2. The screen quit rotating yesterday. I have been looking ever since for information to try to fix the problem to no avail. I tried a factory reset, a hard reset, cleared cache partition, can't seem to find clear Dalvik cache option in Recovery menu. This is really not fun. Does anybody have any idea of what to try next? I am stumped. Device is rooted, but that's all.
