I have an S3 on contract which is about 6mth old. Since the last update a couple of weeks ago the sound has become an issue. If I ring out no one can herar me and if I get an incoming call i am very distant. Also sometimes there is no sound on you tube or notifications. I have been into local EE shop who just said take battery out etc etc and if still the same it will need to be sent back for up to a month which I don't want to do if possible.
does anyone have any suggestions or similar experience?
