Repair test the app store battery is in play, his image is a battery with a heart and a white cross ...
just open the app tells you it took to be the first time you accept and start the analysis and can use it up once a week ...
ooh and he tells you that you download another app of them and there is no problem if the shock is a battery gauge, is also good but for that I must have rooted
you're well .. greetings
