Have you ever face a situation when you forgot your pattern lock and you have to wipe out all data for recovering from that problem?
Many android users stuck at pattern lock screen when they enter pattern in wrong way for 20 times,the real problem begins when they have data/wifi connection turned off and not able to login through gmail.
There are methods available for hard reset on internet for all devices,which solves the problem but not in the way any user would like,in fact this hard reset method also delete all user data from device including contacts,images*,videos* (* if they resides in internal storage).
