I upgraded my phone nexus 4 to Android 5.0 lolly pop, it was over the air upgrade. Before upgrading i had set pattern lock to my phone, after upgrade it is using the same but in settings/security the options to disable the pattern lock is disabled (option none). Also swipe to unlock the device option is also disabled. Pin, Password and Pattern are enabled. please let me know to disable the lock.
Thanks, Harish S
