In addition to the pattern-based tweaks we covered yesterday, Android 12 Developer Preview 2 also a few more lock screen-related adjustments, including a bigger and brighter emergency call button that follows your system accent color and a new enter button that conversely loses its accent color highlight. The lock icon at the top of the keyguard (which disappeared in DP1) is also back, and the break separating the number pad from the bulleted input field has been removed.
