my wife's Galaxy S3 spontaneously wakes up at night while connected to the charger.this occurs in unexpected intervals: the screen lights up and a short notification beep is heard. seems that the longer the phone is still hooked to the charger -this happens more frequently (like every 10-15 minutes).
my galaxy S3 in the same conditions, is charging quietly and nothing of the described happens.
I can't find the setting (?) that is responsable for this fenomenon.
