Lock screen problem

[Phoenix]

I'm using Poweramp beta v3

I've enabled Poweramp lockscreen.

Now while playing a song,if I lock my phone,my phone doesn't respond to my fingerprint...

I have to turn on screen,unlock Poweramp lockscreen and then my phone responds to fingerprint.

Now, I've researched for sometimes and saw that after locking the device if I turn on the screen and off again,then my phone responds to my fingerprint.

I don't have to unlock the phone.

Just turn on the screen and off it.

Then only fingerprint unlock works.

Hope after giving the detailed information about the bug, it'll be fixed soon...

Thanks...
