Completly wipe out phone including os after few failed password attempts

[Gulash]

until now i was using app called "Locker" version 1.1.0 for the purpose of completly wiping the data on the phone including os to be sure that no data like photos can be recorved.

After i bought the new galaxy s20 it seems to not work- the messages of "you have left X attempts before wipe out" As i don't want to lose the phone to check if it will still erase it even though it doesn't show the notification (over hthe password screen)

How can i fix this problem? Or maybe do you have a name of an app like this that will work on galaxy s20?

Thank you.

How would an app be able to wipe the OS? You'd need a custom recovery to do that, root access at the minimum. If you don't have those you have misunderstood what the app does.

Of course if the phone is encrypted a simple factory reset would suffice to render data irrecoverable.
