my Samsung note 3 not booting up Is my phone is bricked or not?The device is not turning on . I thought it was ran out of power. I connected it to my charger. But instead of charging, it shows a blinking  battery symbol contains a circle. When I turned off the charger, my phone started  flashing with the boot logo untill the end of its battery charge and it is not turning on. I'm not installed a custom rom or rooted it.Can anyone find a solution?

Something got wrong with the power button of the phone. I removed it and turned it on without power button. It booted up normally. Thanks for Robert for mentioning about the hardware issue.
