If i leave my phone anywhere within 20 feet, like charging in my front room where my pc is, I can tap the lock on the outside to unlock it.  Not very safe for front door lock.  I've moved the lock to a different location for the time being.  I can force close the app on my phone, but it will restart itself after a certain amount of time goes by. 
 I'm probably going to return it soon.  yes, its convenient to tap unlock it, but not safe enough for my home.
