Correct me if I am wrong but Microsoft owns those. If you are using W10M TP for long then you might have noticed that there is an app called Windows Default LockScreen App and in 3-4 builds back when we could see the app in menu list. Since Microsoft acquired Echo and they also have 2 different lockscreen app, do you think they will bring support for Lockscreen app in W10M ???
I really loved the Live Lockscreen Beta and Tetra LockScreen but unfortunately MSFT killed off both.
:devil:
