NFC and Bluetooth problems

Where is this located? Dropped the phone on the top in an otter box but now the NFC doesn’t work and Bluetooth audio streaming keeps dropping and reconnecting. Bluetooth phone calls are fine. Flashlight is also spotty works and doesn’t sometimes. Is this a connector or a brass pin connector or a bad chip? Already had this issue and phone was replaced under limited warranty. It’s happening again after a drop. I work in the field. Update: it drops connection when the top of the phone is sandwiched lightly Around the area of the mute switch. If I squeeze it, it drops and comes back after a few seconds. It’s a full drop connection
