I have tried a lot of music player apps and several "solutions" but can't seem to make this work. When a song is playing on my phone, I have the option to pause/play and skip on my lock screen. However, if I hit pause and then my screen goes black, when I tap the screen again the music controls have disappeared and I have to unlock the phone and go back to my music app to play again. Even with apps that have controls in my status bar drop down menu, the controls are not an option when the phone is locked. This is all really inconvenient when I have to pause/play quickly at work and can't be fiddling with my phone very much.
Solutions? Apps that specifically operate this way?
