Hi guys, first post here to thank you about the problem I had. As I see many people here had the same when drain the battery full..
I solved it by pressing the power button for about 25 sec and after then charging -not with stoch charger/cable.
My question is: To avoid this problem again what it the solution? Ok.. the easy answer is "do not drain the battery" but I mean until how much % is it safe to use without charging? And something else, same important: can I use my nexus 7 while charging?
