I find stock apps on Navifly Yin 53 more then terrible. When I find out that Navi radio will be ported to Fyt units I was thrilled to finally get decent radio app for my unit, now just to replace music player and most disappointing things will be addressedYes, I already wrote a script for it. Soon to be released.
The extra functionality of the Joying player is that it is also a "folder based" media player. I don't use playlists (these Android units with removable storage are simply not "cache storage safe" enough). I have my collections in folders, for me that is enough. I modded the player a little to have a better layout in split-screen mode (well, I think it is better) and also made a "dark mode" version of the player (not switchable) because in evenings I find the screen way too bright. I tested and modded the uis7862 player and it works just as fine on my current sc9853i.
