Hi. I present the mod Dolby Digital Plus (interface and functionality is the same as that of Dolby Atmos). Theoretically should work on OS 6.0-9.0. I checked only on Oreo and Pie (Samsung Tab A 10.1 LTE and Xiaomi Redmi 4x) and now on 10-Q too. The mod is based on the post from here . I removed the garbage, made it in one archive and added an uninstaller. Install via TWRP to a clean firmware.
Added magisk build.
Builds v.2.5, v.2.6, v.2.7, v.4.4, v.4.5, v.6.0, v.6.1, 6.3, 6.4, 6.5, 6.7, 6.8 for magisk and for TWRP support widgets, the rest are not.
