I can't seem to get it to record anything, so can I assume that I've bust it or does it only kick in under certain conditions or in certain apps? I've tried downloading different voice recording apps but even the ones that allow you to switch mics don't seem to actually switch on the N7 - they just seem to use the mic on the top-right of the device.
Can someone on here test their mics and let me know if it records on both? I know that if I push my finger over the main mic I just get some ambient muffled sound (probably just being picked up by the covered mic).
I don't know how resistant the mic is to having a SIM opening tool pushed quite hard into it, stupid as I feel, I'm sure I'm not the only person to have made this mistake!
