[ S7 edge ] bluetooth doesn't work

Hello /e/ community,

I have installed the last week /e/ on my phone and I have an issue with the bluetooth.
I can’t connect my phone to others devices like my car or my headphones.
My phone don’t see the others devices, and the others devices don’t see my phone.

The bluetooth doesn’t work with S7 in G930FXXU4ESB1 band version but works with older band version like G930FXXU2ERD6.

I think it’s impossible to downgrade the band version on Samsung phone.
Someone have a solution ?
