One UI Version 2.0
Don't know what else you require. Smart Lock worked for a week or so Very frustrating! I saw one response from Mr. Samsung to clear the cache. I did that and that was the time it worked for 2 hours. I WILL NOT JUMP THROUGH HOOPS TO GET IT TO WORK FOR 2 HOURS!
I am also having this issue on Note9 since updating to Andriod 10. Staying unlocked at home has never worked (even though it has BOTH my address and Lat/Long), but I have a Galaxy watch and a Plantronics BT earpiece and they only allow the phone to stay unlocked about 10% of the time. This is super annoying when I'm sitting AT HOME with my watch right next to me AND connected via bluetooth (not on the mobile network connection) and I STILL have to put in my pattern EVERY time. This is a $1000 phone. Get your act together Samsung.
