If already asked sorry but what does it mean clones are device locked.
I used app cloner (paid and legal version) for creating the launcher, weather app and clock.
Basically it helps you create a clone of any app so that you can use it other than the system app too.
You can use my apks/or download from apkmirror.com and create clones and install on your devices, it will work then.
VERY USEFUL FOR INSTALLING ALL PIE APPS ON OREO NOTE 8
Can't share the app cloner apk as I have paid for the same and it can be found via Google search- can't violate rules of the community.
