Hi. I'm referring to my post in page 2.
First of all, the bug is 100% reproducible.
If S2P is playing in the background and the device is locked, pressing the RED button unlocks the device.
Two things can happen:
a) if the GREEN button hasn't been pressed before the RED one, S2P crashes with the PDA showing the today screen;
b) if the GREEN button has been pressed before the RED one, S2P does not crash and continues to play in the background: the device remains unlocked, showing the today screen.
In the b) scenario, if I then press the RED button the screen turns off and S2P continues playing; from now on S2P and S2U2 behave as expected and the integration works very well.
I also tried to run S2P in the background and then suspend the device with the RED button; in this case S2P crashes 100% of the time resuming the device.
Of course, if S2P is not running pressing the RED button does not unlock the device.
Sorry if I did not make myself clear, I'm not an English native speaker.
