no alert for incoming calls, incoming notifications, no vibration, no music or video playing, black screen in camera, keypad slow
nothing is working fine on my iphone 6s plus. I purchased it from US. Model No. A 1634. Currently I m in India. There is no alert for incoming calls, incoming notifications, no vibration, no music or video playing, black screen in camera, keypad slow etc etc. What should I do. I have already restored my phone once through itunes. Also tried in DFU mode but the download fails saying that the network connection is timed out. Help me.
iPhone 6s Plus, iOS 9.3.1
