Previously hidden, stickers are now accessible using an actual button
Sending stickers in Facebook Messenger was possible before today's update, but only using an invisible button that was located just to the left of the "+" button. It looks like Facebook is finally ready to reveal this feature, and has added a smiley face button to access the sticker screen. Multiple pages of smiley face and critter stickers are included in the app, with an optional sticker store that has even more cute critters you can download. Also listed in the change log is a batch of bug fixes, which is always good to see.
This version is available now in the Play Store for all your adorable smiley and critter needs.
