A new update will soon be hitting the T-Mobile Galaxy S4, just a week after its release. It happens all too frequently when a new device gets released, but at least the OEMs and carriers get to the bug squashing right off the bat.
This is just a minor update, probably pretty similar to the Sprint Galaxy S4 that received an update shortly after its release. It does mention something about improvements to the Visual Voicemail app that includes ISIS improvements. Your guess is as good as mine on what exactly that is.
The build number is M919UVUAMDB, and once we get to May 7th, T-Mobile will begin an OTA rolling out process, and the update will be able to get downloaded from the Kies. So keep a lookout on that day for this update, and hopefully it will improve upon the new Samsung flagship.
