um, and this error is succeeded only for 3-4seconds. of course after and before that, it works well. if it is a hardware problem, i think it would be appeared for such a duration from the starting tablet and power-offed automatically.
may be so. they said flash Os and i performed it. but no change at all. purchased Dec. 17 last year in Ali. i emailed them but i heard it may be costed !!
