This is my customized theme of Sony Xperia XZ3/XZ2 Premium as i'm always a big Sony lover and i love their UI and launcher.
- rename the Sony Xperia XZ2 Premium.zip file to Sony Xperia XZ2 Premium.hwt
- copy the renamed file to internal storage > themes
- apply the theme
- restart the phone for the icons & systemui fully loaded
Also let me know if something needs to be added prior to accuracy of Sony XZ3/XZ2 Premium original theme.
Attached also are Sony Xperia XZ2 Premium stock wallpaper.
