Bluetooth of iphone doesn't even work i guess?

Well honestly i been using all kinda Apple products since the biggining but since n i never had problem with any of it but since i start using iphone5 trust me i found many problems only wid iphone5 thats y i stop buying ipad mini .

I know the only problem wid this device is the bumper around the iphone5 . Any wayz the device itself is amazing rest all the best
