Facebook's Android app has today received an update (there's also an overhauled iOS app). The update for Android includes the ability to create events right from your phone, upload multiple photos at once and add emoji to your messages.
Event creation is an extremely welcome update that lets you create events on the go and invite friends right from your phone. The new release also has a better photo uploader that lets you upload multiple photos at once, so you no longer have to use the Facebook Camera app. Lastly, you can add emoticons in Facebook messages, although some users seem to be having trouble finding the option. Head into the Google Play store to update your version of the app.
