I'm having problems with the microphone in my Iconia A500, it's gone as far as giving me an "Audio Problem" message when I try to do like a google voice search. Not good. Called Acer, they said send it back, we'll get it back to you in 2-3 weeks. Called best buy where I bought it, they said Acer should have given me a Return Authorization Number. Apparently that allows me to bring my broken tablet to Best Buy, get a replacement from Best Buy, and then Best Buy will ship the A500 back to Acer. Sounds like best case scenario and how customer service should be. Called Acer back asking for the Return Authorization Number, they had never heard of it and directed me back through level two support and no one has any idea what that means. Has anyone else had to return their tablet for fixing? They're supposed to replace the motherboard in my tablet.....if it comes back with any scratches or dents on the screen or casing, I'm not going to be a happy camper...
