The above screenshot shows the LG K40 Pattern Lock Screen. I failed to draw the correct pattern lock.

I tried to do that same on my LG K40.

To my dismay, I never got any other option to recover my phone. It kept on asking to draw the correct pattern.

The wait time kept on increasing after every few failed attempts.
