Possible iOS 9.3.1 Passcode Vulnerability?
I recieved a text from a known contact containing nothing odd while my phone was locked face up. Once received it swirched to the passcode screen unprompted and I took a screen shot of it:
It doesn't correlate to my passcode that I can tell, but was very odd, unprompted behavior.
