what app are you using

How do you change the language on the lock?

I just got this and when you lock or unlock, it buzzes twice. You can see it locks and then it slightly moves backwards after locking. Do you know why? It's soo annoying to hear that.

No i'm not sure, but I would bet there's a setting you could change to turn that off
