### ⭐ Not too happy with the purchase
            
*by T***A on February 13, 2018*

The one thing I wanted this to do, unlock my phone when I pick it up wearing the ring, does not work. Depending on who you believe, either Samsung has disabled this function, or the ring doesn't know how to to do this. I can get the ring to return the phone to the home screen, so it does work, just not I really want it to do. Not too happy with the purchase.
