Simply powering it off via the Switch will not "reset" the electrons running through your phone. Right now your phone is congested/stuck with electrons in a unstable state. That's what my electrical engineer friend told me before, don't quote me. Hence, to really reset an electronic device is to pull the battery (power supply) out so the memory effect of the electrons will be gone. This should refresh your phone. Pressing the power switch on/off will not give you a true "reset" because the battery is still connected to the phone, electrons are still flowing.
