Good but lack of feature The lock screen is good and minimal but I feel unsafe whenever I leave my phone on a table or if I lost my phone. Please have an option to have security passwords or patterns. Here is my idea  instead of dragging only to unlock  you set up a pattern for it to unlock even without the 3x3 dots as long as it creates the gesture. But if it's not possible  any security measure can do.
