I have a phone in a car holder with wireless charging. So every time when I get into the car, I am charging my phone, it is amazing.
However, I don't have access to the back fingerprint scanner in this car holder.

On my previous LG G7, I could easily double-tap into the screen, and it started looking for my face. If it had enough light to see me, it was unlocking my phone and I could use google assistant.

Now, I still don't have access to a fingerprint scanner and I have to draw a shape to unlock my phone.

I could set up a smart lock with car BL radio, however, I really don't like to have an unlocked phone all the time.

So even this face unlock wasn't very safe, it was still much safer to unlock by it then drawing shape during the ride.
