I found a weird bug. On Security section on Settings, if you use a PIN or a password, there is Quick unlock, which should unlocks the phone straightaway. The problem is that it don't. The phone can't be unlocked at all. The only way is through recovery mode.
I don't know if that problem is about my device only, or others have the same problem too. It might also be a bug from Lineage OS, which RR is based from. If you have the same device please test one of the latest Lineage OS builds to check if there is the same bug.
