Popping/clicking static noise during phone calls on iPhone 5 in Florida
For the past couple of months I have been annoyed by a popping/clicking static noise (kinda like the noise an old antenna TV would make when changing channels) during my phone calls. It doesn't happen on every phone call, but it happens more often than not. The noise repeats every couple seconds, lasting the duration of the phone call. It is not heard by the other caller, just on my end.
Is this a known issue Sprint is working on or should I have my phone looked at? I've had this phone since it came out in October 2012 and didn't have this issue until a couple of months ago and it doesn't seem to be going away.
For reference: zipcode = 32601 crosstreet= University Avenue & Main Street.
