Google are all about innovating, so what can they do different for locking and unlocking the android phone? Google are implementing a pattern unlocking system where you draw a pattern over the 9 dots on the screen to unlock your phone. This pattern can be anywhere between 4 and 9 dots and follows the bellow rules:

• Needs to be at least 4 dots
• Lit dots cannot be reused
• Knight moves can be used
• Moving over a dot lights it
• Can use already lit dots to reach another

Using these rules the phone will be potentially vastly more secure than the 4 digit pin code on the iPhone as there are a total of 389,112 combinations where as the 4 digit system has 10,000 combinations.

But whats the problem?

Well the flaw with this system is the human body and what it produces, when dragging your finger on a touch screen you leave an oily substance on the screen which someone picking up the phone will be able to use to find out the password.
