(error)app not installed m30s(one ui)

[airjordan1]

So, I've been trying to install clockface from the official samsung website but whenever I try to install it, it says app not installed.

I've enabled install from unknown resources 

Turned off googleplay protect. Still getting the same error.

I had installed the same app on my Samsung galaxy j6 and it installed with no errors.

rebuild the clock face apk using lucky patcher app "resign with test signature" option. it will get installed then and run on m30.

Install lucky patcher.
Go to rebuild & install option in bottom right.
select clock face apk and choose last option "resign with test signature"
once done, choose install app option. That's it.
