Confirmed on LG MediaNAV Evolution and X Compact since SFOS4.1

#3

It’s always been like that, independent from the device I used (at least for Sailfish X).

#4

Lucky you! I can’t pair it with my car kit at all (unlike any other smartphone I’ve ever tried). It is seriously broken. Most of the time it doesn’t even ask for the pairing code.

#5

It used to work in the early years on the Jolla1, there was an update to Bluetooth that broke it, that would show charge level at time of restarting Bluetooth, since the Sailfish X program they’ve been using bluez 5 nd it’s necer worked.

I’d like to see it back.
