No audio when phone rings

[DougieBoy]

Any tips on how to get audio on the 6S phone when it rings.
I can get it on the speaker setting and through earphones but not through the built-in speaker when you have the phone on your ear. I can't hear anything.
Many thanks

Try pressing the volume up button as the call comes in.
