The Samsung Galaxy Note 4 is a cellular smartphone that was released in October 2014. The Galaxy Note 4 Model Number is SM-N910, SM-N910A, SM-N910T, SM-N910V, or SM-N910R4 for American variants.
I have lost network connection and do not have a restart option on menu. When I try to hard reboot it only flashes the Samsung word but doesn't vibrate.
