What device are you currently using? Also which update did you recently update to?
Have you tried a phone restart or a full shutdown?
If the following doesn't work, you might have to factory reset to in case there's a faulty driver / software that's misbehaving with the Bluetooth.
If you go down the route with Factory Reset, I highly recommend backing up your device using Samsung SmartSwitch - which will copy all of your files onto your computer. Which then you can restore by plugging it back in once the Reset is finished.
