Idk if it's just to mine but when i'm in a call with my iphone 15 not pro i can i ear what the microphone capture. Just to be more clear, when i'm in a call and i touch the mic near the charging port i can ear it from the earpiece speaker. I tried to do it on my xs max and on a 13 of a friend and they don't do this. Does anyone know why and if i can disable it?
