From speaking with Samsung I was lead on to believe that there should be a new update by the end of next week to resolve audio issues. (UK)
Hopefully this is the same fix that resolved Korean's S3's.
Hopefully it's sooner than end of next week, will keep checking KIES over the next few days
I spoke to Samsung about the audio crackle issue and they suggested I take it to a samsung repair centre for repair? Is there any point? It seems like this doesn't affect everyone or else it would be a bigger issue?
read above.
But basically - people working at Samsung, don't even know their own products
