Question: Microphone not working
Hi. I have bought a second hand iPhone 6s and when I am making an whatsapp video call, the othe person can't hear me. With voice call and FaceTime is everything ok, just the whatsapp video call seems to be the problem. Any advice?
I will take it back to the shop, but is frustrating because I. Don't understand the problem: is it an IPhone issue or an whatsapp one? Thanks
