TL;DR Google has updated the Android Package Installer with the new Material 3 Expressive design language to match the rest of the OS.
The redesigned dialog centers the app name and icon while using distinct filled and elevated button styles to improve usability.
You will need to install the Android 16 QPR2 update to see the changes, as this component cannot be updated via Google Play System Updates.
With the first quarterly release of Android 16, Google completely revamped the operating system’s UI to introduce its new Material 3 Expressive design language. From the notification panel to the Settings app to the lock screen and beyond, Google redesigned nearly every system interface visible to the user. However, Android is a huge OS, so Google missed a few parts during the initial overhaul, such as the Package Installer that handles sideloading apps. With Android’s latest update, the Package Installer has finally received its Material 3 Expressive redesign, too.

After receiving the Android 16 QPR2 update that rolled out the other day, developer Rob Wainwright discovered that Google redesigned the dialogs that appear when you install an app from outside the Play Store. The new layout no longer displays the app’s name and icon at the top of the dialog (the “title”); instead, it shifts them to the center (the “body”). In their place, the dialog now highlights the current action (“Install this app?”, “Installing…”, “App installed”). Demoting the app name and icon to the center places more emphasis on the specific action taking place, which better signals the dialog’s intent.
In addition, the new dialog adopts newer Material 3 button styles. Specifically, the “Install” and “Open” buttons use Filled Buttons, while “Cancel” and “Done” use Elevated Buttons to clearly separate primary and secondary actions. In contrast, the old dialog used standard Text Buttons that lacked a visible container and relied solely on text color to denote interactivity. Furthermore, the installation progress bar now uses the newer Material 3 Linear Progress Indicator. Lastly, Google increased the font size for the dialog’s title, resulting in a slightly taller window, as shown in the screenshots below.
