iPhone 4S Audio Distortion/Crackling iOS 6.1.3
Hi All,
This is my first post here. I'm hoping someone can help! I've never had a problem before that I couldn't fix on any of my iDevices but I am stumped on this one.
I've had my iPhone 4S for Verizon for almost 2 years so it is no longer under warranty. Never had a problem until now. I recently upgraded from iOS 6.1.2 to iOS 6.1.3 and now when I try to play any audio (music, ringtones, video) the sound comes out distorted. It comes out distorted whether i play it on my headphones, the iPhone speaker, on a phone call, or an iHome. It doesn't come out distorted on bluetooth or airplay.
It starts the same each time I reset the phone: it comes out fine until I play something bass-heavy (even if bass is turned all the way down) then everything plays distorted. At first it is distorted on the right channel only so I use accessability to move it more to left channel but after a few minutes of that the left channel becomes distorted as well.
This is what I have tried to fix the problem:
System Restore (multiple times) - I have restored with and without a backup, I thought that the backup may be holding some bad code so I restored from scratch and reinstalled everything manually to no avail.
DFU Reset (multiple times) - Didn't work
Tried to restore back to iOS 6.1.2 but was unable to do so
Un-Synced my music library and only had Pandora installed as a test but it failed
Took it to the Apple store but they were unable to pinpoint the issue and told me I would most likely need a new phone (which I'm definitely trying to avoid)
Has anyone ever seen anything like this before? I really can't figure out whether it is a hardware or software issue. It seems like a hardware issue since my other iOS devices (iPad, Nano, Classic, MBP) all play everything fine, but since it started immediately after downloading iOS 6.1.3 I think it could be software also. It is just my iPhone that is having issues. I haven't seen any other posts with this exact issue so I wanted to start a new thread.
Thanks Everyone!
