Welcome to BigBlu, a Unique Custom Theme for the Substratum Theme System. Using Black, Dark or Transparent backgrounds and Blue accents, BigBlu will transform your device, and theme some of your favorite apps. Big Blu gives you the option to choose from multiple buttons, or no buttons at all, and they will show throughout the theme and across many themed apps. Just choose the button you want when enabling the Android System overlay and your ready to go.

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.

***Please reboot to get all theme resources to set and update*** TY


BigBlu is tested on and fully supports N7.1.1-Oreo 8.1.0 - DU, RR, Screwd, AICP, GZR Roms, AEX, Aosip, Havoc, FireHound, MSM Xtended, OwnROM, LR, Franken, and CM14-15 using the Substratum Theme System. BigBlu should work across many different roms and devices. If you have any issues after applying the theme, please use the Substratum Rescue zip or the Substratum Rescue Legacy zip. 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.

☆For Gboard to theme use v6.1.171 or lower and choose Material Dark. If you want my buttons/keys to show enable key borders in settings☆
