Android Central gives us a sneak peak at Android 4.3 changes. The update is minor but includes some nice new features such as the phone automatically suggesting phone numbers from your contacts as your dial, the 4.3 camera updates which have already been seen on Google's HTC One and Samsung Galaxy Play editions, and some new settings such as allowing apps to turn on Wi-Fi, compatibility with Bluetooth Low Energy and more.
