WhatsApp is reportedly working on incorporating support for notification bubbles, a feature that allows conversations to be displayed in a floating format, enabling users to switch between chats and other applications easily. This feature is currently in early beta versions and is not yet available to the general public. Unlike Facebook Messenger, which uses a semi-custom solution for bubbles on non-Pixel devices, WhatsApp aims for a more cohesive implementation that aligns with Android's native bubble functionality. There is no official timeline for the rollout of this feature to all users.
