Is it bad to blow out the dust from the charger port, or headphone jack port?? Sometimes I'll feel a little bit of saliva spit out, I see there is water sensors in the both ports...just wondering if anyone has triggered these sensors by trying to blow out the dust? Also is it necessary to blow out the dust from the two ports? I mean is it going to effect my phone if I have a lot of dust in those ports?? Could the dust work its way under the screen via either of the ports??
