Facebook Messenger update introduces new selfie mode and AR stickers
The update is quite important for Apple fans who own older iPhone models that don't include the Portrait mode feature introduced with the iPhone 7 Plus launch. Even if your iPhone doesn't have dual cameras, Messenger will be able to produce a selfie solely through software means.
Just make sure that you choose the new Selfie mode from the five different camera modes that Messenger now offers to users: normal, text, video, boomerang, and selfie.
All the new feature announced will be rolled out globally to both Android and iOS devices today. You'll be getting this update regardless of whether you have the redesigned app or the older version installed on your phone.
