Ever wonder how secure is your mobile phone. Nowadays we carry out all our work, transaction, store data, contact, messages, Facebook, twitter..etc on our mobile devices. And what we do to protect it just a pattern lock which can be easily opened and anyone can get access to all your data. So here are some pattern locks which are difficult to guess and difficult to draw.
Well in the start it would be difficult for you even but with practise and opening it again and again you will be able to draw it perfectly easily and with more speed every time you do so. Believe me I have tried it. So even if someone watches you drawing it won't be able to guess it.
