Hi ! Its a new device, 5 days old ! I noticed a strange sound in the upper right corner( +,-, silence button ) while moving my iphone. I searched a bit and found that it could be the AF of the camera, but the camera its on the other side. I also tried to hold power button, +,- buttons, but still the same sound ! What could it be ? The sound is a bit annoying ! When u pay soo much for a device u espect it to be like it should be, and not like some cheap stuff.. Any help is appreciated ! Thanks !
