SGS 42mm, owned since June (late June). It's in perfect condition, but I think that the microphone is defective. I have tried several times to append voice recordings to text messages to friends (rather than the rote responses available) -- and the microphone greys out immediately when I hit 'respond'. I asked a friend - while sitting right next to him - to send me a text with voice recording from HIS SGS. The microphone was immediately available on his watch, and the text with vocal attachment came through perfectly. What the heck!? It is connected via both wifi, bluetooth, it is not in Airplane mode, and my cellular connection is on. I can send text-only text without any problem. I would appreciate anyone's advice here!
