I never saw the lock screen as a serious protection mechanism, but more like a screensaver, mainly to protect me from pocket-dialing. For me, its more like the key lock on old dumbphones than like the pin code lock.

And since even the pin lock was trivial to bypass by law enforcement or professional criminals (you could buy special devices to unlock the phones), I don't expect that my phone has any really serious protection. I know iOS devices are harder, but I'd expect the police or serious criminals to be able to crack my Android phone in seconds. Which is ok, as long as I'm aware of it. Of course, if my phones lock does turn out to be safe, thats great.
