I had this bug too, with my gear s.
2 way to connect:
1. Reinstall ROM and connect your gear before you make any settings (exept startup).
2. Delete samsung accaunt an clear gear data. Restart. Then connect to samsung accaunt ang gear.
I`m make clean install v1.01. But add new bluetooth device in Smart lock still FC :( Auto brightness work good, only on max brightness. How can I reduce the minimum brightness?
Other works fine! Almost perfect ROM. Thank Geiti94! Great work!
