RCS is designed as the (eventual) successor to SMS and MMS, but it's a bit of a mess right now. Several carriers have their own implementations of the standard, often incompatible with each other. Google's Jibe RCS Cloud is quickly gaining ground, but there's still only one US carrier supporting it - Sprint. Now Samsung has announced its own RCS cloud.
A little over a week ago, rumors of yet another Galaxy S4 variant hit the web, but this time it was packing support for LTE Advanced, the successor to the LTE we all know and love. That device is now official on Korea's SK Telecom, and it not only has support for the fastest mobile network on the planet, but also Qualcomm's new Snapdragon 800 chip. Early benchmarks of the device are in, and it crushes everything we've seen thus far – up to and including the "original" Galaxy S4. Take a look:
Past the Snapdragon 800, other specs of the S4 LTE-A seem to be largely the same – 5-inch Super AMOLED display, 13MP camera, and the like.
Despite the fact that we've already seen the phone previously known as the HTC Holiday running on AT&T's LTE network, the first carrier to get this monster device will in fact be South Korea's SK Telecom. The phone will be released under the moniker Raider 4G, and packs some pretty serious hardware under the hood:
4.5-inch qHD display
1.5GHz dual-core Snapdragon
8MP rear shooter, 1.3MP front camera
16GB internal storage
Android 2.3.4 with Sense 3.0
There's no word when this phone will be available outside of South Korea, but considering AT&T just started lighting up its LTE network and doesn't yet have a smartphone available that supports it, we expect a US announcement fairly soon.
