This update made significant changes to the UI to comply with the new Material Design 3 guidelines.
First, WhatsApp introduced a redesigned interface with updated toggles and action buttons. Now, the new beta has added rounded alerts that follow Google’s design guidelines.
For example, the updated notifications within the app have gotten pretty rounded edges, giving WhatsApp a modern and solid look. This improvement not only improves visual aesthetics, but also ensures consistency within the application.
Note that this design update is currently only available to beta testers who have installed the latest WhatsApp update for Android from the Google Play Store. However, the update will be available to all users very soon.
