Hi. I expected to get my hands on iBasso DX220 already but the plans was delayed so I decided to update iBasso DX200 ROM with new MangoPlayer app from DX220 model instead. This is still the same ROM plus new app so it should be stable. 🙂
-Based on firmware version Oreo 8.1 V1.06.041
-Added MangoPlayer from iBasso DX220 1.0.9.092 app
–Yalp Store is added as Play Store’s alternative (I still keep Google services for those who want to install Play Store through other means)
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-Revamped MangoPlayer UI with improved user experience
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
