Screen does not turn off while waiting for me to enter unlock pin

[AC Question]

GS5. Phone locked. Somehow it is woken up (either press power button myself, or magic that happens to my phone while whiling away its day in my pocket). It is waiting for me to enter unlock pin. But if I fail to enter a pin within x many seconds it should go back to sleep. Instead it stays on indefinitely lighting up the inside of my pocket and draining my battery. It is also providing a lot of heat, but I'm not sure I really need this in my pocket.

Welcome to Android Central.

Presumably you have set an appropriate sleep time in Settings, Display, Time to sleep? It isn't set to Never?

(I'm the OP)

Yes, of course I set the sleep time. The display _does_ turn off upon timeout, _unless_ I'm at the 'type your pin' screen.
