WhatsApp is introducing a new feature through its latest update, available via the Google Play Beta Program, which brings the app's version to 2.24.21.34. The update allows a select group of Android beta testers to experiment with chat themes, giving users the option to personalize their messaging experience by choosing from 20 different colours. Initially rolled out for iOS users, the feature is now extending to Android devices. The update offers flexibility, letting users apply different themes for personal, work, or group chats, making it easier to visually distinguish between conversations. The feature is currently available to a limited number of beta testers to gather feedback and ensure stability.
