I love Android’s pattern lock feature and I wish to use it in my Windows Phone (Lumia 525). Is there any way or App to use that feature? Does any Windows Phone have Pattern lock feature just like Android?
As of the writing of this, pattern unlock isn't supported on Windows Phone. The only option for protecting your phone is currently a PIN code.
That said, it seems there is an unofficial app in the works that would add pattern unlock using the new Live Lock Screen feature in Windows Phone 8.1:
It doesn't seem to be actually available yet (at least I couldn't find a download link anywhere), but is something to keep your eye on nonetheless.
If you are looking for an open source control which helps you to do enable pattern lock in your application then you can follow this blog Pattern Lock for Windows Phone which has a similar control and it's free.
