Swift for Samsung is a bedrock theme with over 150 overlays, each with a dark or black option, supporting the Samsung S7, S8 and 8 note, including S8 Oreo.
Update the theme of the Play Store. After the update, do a clean installation of overlays: Uninstall all overlays of the “Manager” overlay, which you will find in the left navigation drawer inside the substratum. When this is done, install the new overlays followed by a reboot. And remember to uninstall all overlays before firmware upgrade (OTA).
