I have old android phone LG Prada 3.0 - it has custom Android 4.0.4 with black/white icons everywhere (Prada Theme). Except downloaded apps.
I would like to get the same theme to my new phone running Android 8.0 Oreo (Sony Xperia XA). So far I have managed to get all the black/white icons from old phone. I have also found some apps that let me change icons on my new phone but I can only change them in home-screen. If I press the "apps" button, original icons are still there.
Is there some theme extract/import app that I can use?
I would like to make my new phone look as much as possible as in old phone...
