Hello guys !!! I have G10S and i charge it like 3 hours and turn it on, after 20 minutes he starts to turn off ... As if I didn't even charge it ... At the beginning there are three lines, then soon two, then one and after 15 minutes it turns off ... I tried it update but nothing happened ... I bought it from a friend. I can give it back to him, but I would like to know what I need to do to fix him... Can the GT10S be replaced with new batteries ... Please help!
