WhatsApp is testing a new feature that allows users to react to messages using stickers, enhancing the platform's expressiveness. Currently available on the WhatsApp beta for Android (version 2.25.13.23), users can long-press a message to access a customizable emoji bar, which now includes stickers. These stickers can be from WhatsApp’s official packs, third-party apps, or user-created designs. This feature aims to provide more expressive reactions than standard emojis. Meta plans to expand this feature to iOS beta testers soon, with a full rollout expected in the coming weeks. Additionally, WhatsApp has introduced enhanced chat privacy features.
