The T-Mobile GALAXY S 4 has only been available for a short time, however it looks like the carrier has already announced a software update. In fact, said update is available as of today and those with a T-Mobile GALAXY S 4 will be able to grab the update over-the-air or by way of Samsung Kies.
The changelog is on the smaller side and while the handset will stick with Android 4.2.2, the baseband version is going to change from M919UVUAMDB to M919UVUAMDL. Otherwise, aside from the baseband version, this update brings improvements for two items. Those two items include the ISIS app and the Visual Voicemail app.
T-Mobile has said the update will measure in at 168MB in size, which sort of sounds large given the small changelog. Needless to say, those with a T-Mobile branded GALAXY S 4 now have a few options to consider -- sit back and wait for the update notification to arrive or fire up Kies and take the manual update approach.
Bottom line here, this seems to be nothing more than a small update to fix a few bugs. Basically, that is our way of saying that unless you are having issues with either the Visual Voicemail or ISIS app you may just want to take the casual approach and wait for the update notification to arrive.
[Update] Looks like the update has begun to show up and as a result, we do have some news on the file size. It seems the update is actually a bit under 20MB. Our first user report (thanks Dustin) has the update as being 19.58MB.
