CORRECTION 1: It appears this bug exclusively pertains to the HTC One, rather than Android as a whole. Most likely something to do with the HTC Sense software.
UPDATE 1: A Reddit user seems to have confirmed that HTC have issued a fix. I’ve yet to update and test. If anyone wants to confirm, I’m on Twitter.
One can very easily bypass the HTC One lockscreen by swiping up from the bottom center of the screen during restart. You have a less than 500ms window in which to swipe up before the lock pattern is enforced. I recorded this video to demonstrate the exploit. Once in, one has total access to all the phones settings and apps. This is a very serious exploit that needs to be fixed.
