HTC has been upgrading its normal-sized smartphones in the US to Android 4.4 KitKat for a little while; now, the giant One Max is getting its turn. Sprint has started rolling out the OS update to the 6-inch behemoth as of today. As with earlier upgrades, the One Max isn't getting Sense 6. This is more of an under-the-hood tweak whose most conspicuous additions (besides KitKat itself) are new Bluetooth device profiles and cloud printing support. Verizon hasn't pushed out a corresponding KitKat upgrade to its One Max variant, but HTC says the patch is in certification -- here's hoping that it comes relatively soon.
