I've done everything to fix Smart Lock. Stop wasting time trying to fix this bug with internet tutorials. This is an Android bug. The problem occurs with any manufacturer's smartphone. What happens is that after 4 hours of inactivity, the Smartphone asks for the credentials again (OK, that's how Smart Lock works). The bug is: after entering the credentials (after 4 hours of inactivity) the smatphone does not understand that you have disabled it and that it is time to know that it is in a trusted place. Clear cache or even reset your smartphone to the factory default will not fix the bug because the next time it goes into inactivity after 4 hours, the problem will return.
