So I have 2 problems with my iPhone currently. 1) whenever I make or receive a normal call. My voice is very very soft to the other party. Only way to solve this is to talk using speaker phone, which is a nusiance. It should not be a hardware problem because my microphone works fine whenever I use any social messaging app (whatsapp, wechat, line, Skype) to make a call. Updating to the latest iOS does not help. How do I solve this? 2)so I went to buy a wireless Bluetooth earphones with microphone to help with this issue. But the problem is, whenever I pair and use the earphones, my keyboard in my iPhone is somehow disabled. Meaning I cannot type, the keyboard just does not show up, in any and every application, i.e. Messaging, notes, any social messaging apps or games. It cost a pretty penny and is a major hindrance if I can't type while using the earphones. Please help!! Thanks in advance.
