Your device DOES NOT have a native theming engine to use without root, thus, THIS WILL NOT WORK ON YOUR DEVICE!
We separated the Theme Killer into a different package, available here, completely free! https://play.google.com/store/apps/details?id=projekt.theme.killer
An add-on to enable Samsung mode for Samsung devices (Nougat 7.0 - 7.1.1) on our main theme engine, Substratum, downloadable here: https://play.google.com/store/apps/details?id=projekt.substratum
This is required to use Substratum regardless whether you are rooted or not, since it enables a series of features specifically for Samsung users.
Thank you to all our testers in making this possible and the people who believed in us enough, you guys were great motivations!
This is a
add-on as a gesture of thanks to the team!
