Official firmware 4.0.26 Since I have problems with my touch screen, it hangs and does it reacts more left after the day or worse games in the tablet works correctly only does the screen reacts plus.depuis the official 4.0.28 update product that does more, like with 4.0.28 root no problem, I put it in against the 4.0.28 this root deodexed it again, I do not understand why this one dev can help me understand before possible return to service? thank you
