When i will have some time I will make a video with the iPhone issue and i will update my post here. The iPhone main camera (back camera) has a small blur given by autofocus sometimes.can be a iOS driver or coding issue and not hardware?.the Facebook Messenger and WhatsApp use a microphone that can be in bad condition? May be the Rear Microphone between the main camera and flashlight led on the backcover of the iPhone?.the FaceTime use the same microphone which work’s fine like in local recordings.the local audio and video recording use a single microphone which work’s fine (possible buttom or front).Why i tell that “loose the sound routing”? Because when i start a Facebook Messenger audio call, the receiver can hear me only if i press Speaker icon but i can’t hear him when the Speaker button is on (like the walkie-talkie). The iPhone loose microphone sound routing only in internet connection streaming. That means all the microphones are ok as hardware condition. The tests were made both on wifi and cellular data.Įach audio and video recording made with Voice Memos, Telegram, Facebook Messenger are ok all the microphones works on local recording. All the app’s mentioned here have permissions activated in settings for microphone and camera. Identifiable by the model numbers A1549, A1586, and A1589. On FaceTime the microphone works fine but on Facebook Messenger, WhatsApp is not working. Released on September 19, 2014, this 4.7' screen iPhone is the smaller version of the iPhone 6 Plus. I have the same problem with my iPhone 6 plus latest iOS with automatic updates turned on for all app’s.
