when I receive a call, the caller cannot hear me… as if I have phone on mute. cannot find a mute button

You’ll find it on your dial pad click on the icon that has a bunch of squares, microphone with a line across it. I would do a " SIM card pull" as in removing the the back and pulling out the battery and the sim card waith minutes and reinstert and assemble. Prior to this look into Cameron’s advice; if its only one person it an issue on the end of that person; if its everybody or an ew occurrence may be a network issue. Then proceed to my advice

People cant hear me on the phone i can hear them please help me
