high pitch sound

[scotth45]

Today I got a new rockfish car charger from best buy and after using it in my car I could not make a call and heard this high pitch noise people I called could not hear anything when I called. After a reboot this stopped but could this be from the car charger ? I have never had this noise before so I'm afraid the charger might screw up my phone somehow.

Thats the exact samething mine has been doing the past two days. I have not used any charger other than the OEM one that came with it.

Im getting a new in box replacement on Sunday. Gotta love VZW Fedexing that sucker for Sunday Delivery.

Mine stopped with a reboot but I thought maybe it was the charger that sound really hurts the ears I thought I fried my phone
