Do screenshot on device greater than 5.0 (Lollipop) without Power and Vol Down
Simple words: this is only application I could do screenshot on my unrooted Lollipop device.
Long words:
if your device is lower than version 5.0, ignore it, it won't work.
most screenshot app claim they support Lollipop, actually they just ask you press Power and Vol Down.
My device panasonic DMC-CM1 does not support snapshoting with Power and Vol Down.
So that is why I build this app ...
