Android 12 brings a major redesign of the user interface, but Google is still working on the details. Android 12 Beta 2, which launched on Pixels last week, makes it easier to keep track of the duration of the current call with an indicator in the status bar.
Typically, when you exit the Phone app, a notification is created that shows the duration of the call and that you can tap to quickly return to the Phone app. This is still there, but it does require you to open the notification shade first.
Android 12 Beta 2 adds a call duration chip to the status bar
Android 12 skips this step by placing a chip in the status bar that shows the duration of the call. Note that “chip” refers to simple pill-shaped UI elements in Material Design. Typically, chips can be tapped to trigger a specific action, and this appears to be the case here too.
Presumably, third-party apps (e.g. Skype, WhatsApp, Viber, etc.) can also use a chip to show the call duration and set up a custom action when the chip is tapped. You can’t try the new feature because the current Google Dialer app doesn’t support it.
I didn’t think of trying that out, but yeah, tapping the chip opens the calling app with a smooth animation. pic.twitter.com/ZEtrUQ06XU

This is also why the chip in the video above doesn’t open the phone app – it’s not the phone app that created the chip, but a custom Magisk / Xposed module from the developer kdrag0n used to try out the new features of Android 12.
