Well still no fix, no professional service can provide any understanding or reason why, even Samsung have been completely stumped by it. They all just go round and round explaining and suggesting the same typical things of what to do but none worked despite telling them that consistently;
-Software update, didn't work.
-Checked and switched on/off all settings like Airplane, Volume and Silence modes, Do Not Disturb mode, even all settings given a basic reset, but didn't work.
-Software reboot, didn't work.
-Full Factory reset, didn't work.

Now even the normal microphone doesn't work, still won't read similar tray 2, still won't play the notifications or ringtone for any apps. It's basically now just an expensive paperweight because even updating to latest software didn't work. So had no choice but to upgrade contract to a new phone, and couldn't even use the old phone as a trade-in coz it doesn't work sufficiently, they said it wouldn't be worth much not working like that.
