Signal Android includes built-in emoji functionality to enable consistency between platforms and to support older Android devices whose set of emoji may be outdated or incomplete. However, you may prefer to use the system emoji that shipped with your device. Here's how to enable that option:
- Launch Signal.
- Tap on the menu icon in the top-right corner of the screen and select "Settings".
- Tap on "Chats and media".
- Enable the "Use system emoji" option in the Chats section.
