Heads up, Samsung Epic 4G owners. Sprint has announced that a new maintenance update is now rolling out in stages to the Epic 4G. The new update, which is version FC09, actually began pushing yesterday and is expected to hit all Epic 4G owners within six weeks. It's actually a rather small upgrade, packing in a fix for a bug that'd cause a force close error when answering a call. The Sprint Connections Optimizer is also included, which is a feature that'll automatically turn on and off the Wi-Fi and 4G radios on a device at pre-specified locations and times of day in order to help save battery life. If you haven't already received the notification for the update be sure to hop into your settings and check manually.
