Application error, What a kind of behavior is this Samsung

[Anonymous]

A21s is your company's phone only, Samsung 

Very disappointed

Can't Believe ☹☹😡😡

A21s runs on One ui core. Good lock is not compatible with one ui core version as of now

Thanks for information 👍

You sure about that it isn't a 3rd party app?

There is no such statement from Samsung about official good lock support in one ui core version phones. Many M series users including M31s users are flooding post about why it isn't available for their devices. So.

M31s has one ui core and goodlock apps are not compatible for it too.
