One of the latest tweaks to hit Cydia is the PatternUnlock offering by Jonas Gessner, and although it offers a core feature set that we have already seen on iOS with the likes of AndroidLock, it innovates by not only implementing it a lot better but by also adding additional pro features.
Android introduced a very different kind of entry protection in 2008. Named Pattern Lock, it allowed users to swipe in a specific way across 9 dots to unlock their smartphone. It is arguably easier to input and technically much more secure than a 4 digit PIN code. But, as time goes by, people found ways to bypass it. The first method I’ve heard of is actually pretty simple: if your fingers are the least bit oily, they will be leave smudges in line with pattern you use to unlock. If an intruder, then, observes the smudges, they may be able to gain access to your phone. The second method is to just go by trial and error as, in my own personal experience, I’ve noticed a lot of people use letters of the alphabet (such as V, D, U, O, etc. alphabets that can be easily recreated in the pattern lock).
