I wish I could released this sooner but I have HiFi Show in Thailand requiring immediate attention last week so I finally got time to work on it after the show with Nimitra. This new version also won’t wipe your data anymore so enjoy free non-wipe upgrade. 🙂

-Deodexed
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)
