note 5 not responding

[overthelimit]

Samsung Note 5 is not responding; it is on; left it on the charger all night; the little blue light top left has not stopped flashing but the screen will not open; calls go straight to voicemail; no notifications come through either...and it is warm to the touch.

I've held the power button for several seconds and it will not power off.  Any suggestions ?

How old is the battery on your phone? The problems you are conveying sounds like the battery can not hold a charge.

the phone is about 2 yrs old.  i was able to restart it and it is charging now.  hopefully it was just frozen.

thank you.
