Samsung users BigBlu may theme some of your user apps but this theme is meant to run on its own framework for AOSP and CM based roms it was never built for TW. Thank you

For Nougat you need to be on a rom that has all the latest OMS commits for this theme to fully work.

Please use the BigBlu Android System Overlay to get the best overall experience. BigBlu was made to run on its own Framework. Go thru the list and check the correct overlay choices for your rom if you have any issues choose the other choice in the overlay list.

You can also go into recovery and navigate to the .substratum folder and delete the " current_overlays.xml " or the individual overlay that is causing issues in data/app and reboot.
