Using MMA 1.2.0.0618 with Pro license on a Samsung Galaxy S2 Plus with CyanogenMod 13.0 (based on Android 6.0.1).
- Start playing a song
- Press and hold fast-forward or rewind
- While pressing, also tap the Android Back button.
- Let go of everything.
The Now Playing view will minimize since you pressed the Back button but the song will continue to rewind, eventually showing x5, x10, x30, x60 on screen even though you have let go of all the buttons. Subsequently going back into Now Playing and pausing and starting playing again does not
halt the rewinding/fast-forwarding! There is nothing you can do to halt it except kill MMA or restart the phone.
I have been hit by this bug multiple times while at the gym, while listening to an audio book and wanting to rewind a bit. I have the phone in an armband and apparently it can fog up behind the protection plastic and trigger multiple different button taps accidentally that way.
