My Samsung Tablet S 8.4 does not switch off or restart by pressing and holding the power button. Is
Only solution now is a hard reset. Going into recovery mode and wiping the entire device is the only way out. The secure lockscreen is there for a reason, and sorry to say this, but you can't register
fingerprints without setting an alternate password...
Usually turning the device on by holding the power + volume up + home button together until you see the Recovery Menu works.

went for the factory reset (Volume up, Power button and Home button).
----------------------
Press and hold the Volume UP and Volume DOWN and Power button at the same time, 10 seconds. Tablet restart.
-------------------
After about eight hours the battery didn't die. Got frustrated... continued looking at multiple forums. Found that someone managed a reboot on a Tab2 with combination of volume and power hold for 10 seconds.
Well it worked... Volume down, then power button hold for 10+ seconds and the unit rebooted.

even when I held the power button for 30 sec it didn't do anything, what did work was hold the power button , volume down and menu key for 10 seconds and it will reset
