BLUETOOTH help

[Tinkerbell]

Hello lovely techs people.

I am still in the U.K.

Husband says that on his Samsung tablet [SMT50] has an issue with Bluetooth.

When he swipes across to put Bluetooth on in settings the little line thingy goes blue but then fades to grey.

I know it’s a bit vague, but anyone give me a clue as to what he has done. I’m presuming he’s inadvertently pressed some sort of turn off button? He’s technically challenged, can build you a house but not turn on a computer

As we are heading into five months apart he’s very dependent on listening to his music

I’d appreciate any ideas

Thanks
