In an effort to be the ideal place where your photos are stored, Facebook has publicly released a new feature called photo sync for its iOS and Android apps. When enabled, photo sync automatically uploads every picture you take to a private album on Facebook. You’ll then be able to pick and choose which photos (if any) are suitable to post to your Facebook Timeline.
Once the update is available to you on Android or iOS, you can enable photo syncing by going to the photos section and tapping on the sync option at the bottom of the page.
If you have a limited data plan, it’s recommended you turn photo sync off until you get on a Wi-Fi connection. Facebook promises uploads over a 3G or 4G connection will be around 100K for each photo. Facebook will also temporarily disable photo sync if the device’s battery is low.
