The Xperia Z (C6606, C6616) saw a new firmware with build number 10.4.C.0.793 certified earlier this month. This has now been followed up by a new incremental build with version number 10.4.C.0.797. We still don’t know whether this is a specific carrier release, say for T-Mobile in the US or whether this will hit all C6606 Xperia Z LTE variants in North America. If this does end up being released, we’ll keep you posted.
