As we all know the p9 doesnt have an eq from scratch , but i really need one to get my JBL Charge 3 to sound as good as it should . Poweramp is a given when it comes to stored music, but I need an eq that works with Spotify! Believe me I have tried many, many apps from playstore without finding a good one. Most of them dont work with Spotify and the ones that do "work" lowers volume alot and/or crashes etc. . Help! ?
