With the Z9X/Z10 Pro Beta Firmware v6.0.45 Zidoo updated Music Player to Version v6.7.6
I’ve created a modded APK for the Android 6/7.1 devices based on the Android 9 code from the Z9X firmware v6.0.45_G beta
It took me three days to figure out how to create working APKs for the Android 6/7.1 devices based on the Android 9 code from the Z9X firmware v6.0.35.
Update 2020-09-10: Since Zidoo released an update for Z9S with even more current versions of their apps, the use of modded APKs is not necessary for now.
Zidoo announced a new Music Player 6.0 on the product pages of their upcoming model .
