It's been about seven months since the all-but-forgotten EVO 3D saw its last over-the-air update, which brought Android 4.0 to the handset. Sprint hasn't given up on the 3D oddity just yet, however – a small update will begin making its way to the device beginning on February 21st.
It will bring build 2.95.615.4, and include a couple of small fixes and one lone "enhancement:"
Sprint Connection Optimizer
AVI Files unable to stream or play via DLNA
Launching Messaging app loading time
Yeah, it's not very exciting. Nonetheless, when an update hits your phone later this week, at least you'll know what's in it.
