Forgot the Pattern lock pattern in lollipop. How di i reset it? I locked my mobile with pattern lock. I forgot the pattern. In lollipop there is no option "Forget Pattern". I used Android Device Manager to lock my mobile. It Locked. But I does not ask for the password. The Mobile Screen is like bellow. How to Reset it?
The first and easiest way is resetting that Tushar's answer is about. I'm afraid there is no physical offline way to bypass the lock.

Although, there are apps that have access to the lock screen and can actually bypass it.

For example Samsung's Knox and Google device manager (Read a howto here), but they have prerequisites. You need to sync your device with them. If you have, be happy. If you have not, I can think of other ways.
