Actually what does the rear microphone do on the ipad mini R? We also don't use it as a phone so why do we need the microphone ar?
So if we use a ipad mini 1 on the ipad mini R... And cover the microphone.. Any implications ?
Facetime. Skype. Google hangouts. Siri.
There are actually quite a number of use cases for a microphone on an iPad, but few people take advantage of it.
Siri is particularly good for setting quick alarms. Try using Siri and saying "wake me up in 15 minutes".
