Android O's fourth developer preview was released today, and you know what that means: more feature spotlights. We already covered the new octopus Easter egg, but there are still a few other changes, even in the final developer preview. The lockscreen and notification panel have both seen a few minor visual tweaks.

Let's start with the lockscreen. It's apparent that the clock has gotten a bit smaller. The date's font looks to be the same, but it's no longer all uppercase. You might also have noticed that the text has changed from "No SIM card - No service" in the DP3 screenshot to "No SIM card - Emergency calls only" on the DP4 screen, but we're not 100% sure if this is completely new, as we've seen the latter on previous Android versions before.

Moving onto the notification panel, the same "No SIM card" difference is present. Additionally, the font for the date (in this case, "Mon, Jul 24") has been swapped out for a wide font. The battery percentage number is now bold. And lastly, your carrier's name in the top left and the time in the top right have been pushed in a bit so that they're more in line with the toggles.

I'm not sure why any of these changes were necessary, and I personally prefer how things looked on DP3, but Google will be Google.
