any one has problem with PocketMusic Box?

[Guest JasonMa]

Problem description:

Enable Lock screen when wake up.

Play music with PocketMusic Box, enable power-save option, after 30seconds, screen turn off.

Once there is a incoming call, screen wake up and show the slide-to-answer/ignore button. Once you slide, the phone went no response.

i even tried to install S2u2, but the result was still the same.
