No mic or reboot issues with mine. Can't use it at the moment as I am waiting for my Inivisible Armour stuff to 'dry'. If I knew the stuff was so silly to install, I would have just got a cheapo ebay screen protector...

Battery is holding out fine, just a little disappointed with the flash. "Get on my horse" by Weebl is laggy on newgrounds; although, it could just be the ads slowing it down.

Half a battery left, and I got up at 5:30! Reasonable usage, all day 3G and wifi turned on. Tried out the FM transimitter in my car and ran it alongside navigation for half an hour. Currently sitting at half battery
