Can't find the original update thread,but 485 mb update this morning to 4.4.3 sense 6.0 software version 6.07.1540.1. Downloaded and installed,still checking it out.
Downloading my 4.4.3 update now. Hope this helps with some of the crazy battery drain that has been going on lately. Phone will be good for a few days and then run hot as hell and chew 10% or more an hour.
