SOLVED: It was Colorflow, i thought disabling in the Settings is enough, but i doesnt. Every other Tweaks can be installed.
Hey Guys,
after i updated to 8.4 and jailbreaked my phone, i have problems with the stock music player.
Everytime i play a song and click on the songbar, the app crash. If i dont tap the songbar, then the app close itself after about 3 minutes.
These are the tweaks i have installed now. Colorize and Colorflow are disabled, just got them installed to know when they update.
This is what i mean with songbar:
If you have some questions or the same problem, please tell me.
