Hi!

Just want to give feedback on the Powerebutton:

I have by mistake turned of the phone a few times by press the power button instead of volume. Especially when using camera application. It would be great to use powerbutton as shooter but I guess its not possible?

But atleast there should be longer delay, around 10 sec, before shutdown the device. Maybe also some kind of UI/sound warning before it shutdown.
