[BrazilianStudant]

Good morning friends, recently bought my mbIV, yesterday I slept with her arm and when I woke up was without her, tried to call several times and did not show anything on the screen ... Shows that is synchronized with the phone and when I put the charger, appears the notification on the phone, but the bracelet itself shows nothing.
