I already take basic precautions against phone snatching, like setting extra PINs for critical apps, using separate profile on walks and I have FindMyDevice from f-droid. But there is one obvious, very simple thing I'd like to add as well. On my main profile, I'm always connected to my smartwatch, is there a way to make my phone lock when the connection is lost? I'm guessing it would have to be an app with admin permission, but I can't find any.
