When i long press power key and switchoff my device, its not getting switch on again. if i simply press the power button once and select "Switch Off!" then i can turn the device on. if i long press the power button, i must restore the battery in order to power on the device.
I know this problem, I guess it simply needs a little bit longer to power off even when the white LED is already off. Simply wait 10 or 20 seconds and then power on again, it should work.
