T-Mobile and AT&T Samsung Galaxy S 4 update is ready for those who own Samsung’s flagship on either of the two carriers. The T-Mobile variant’s refresh is version M919UVUAMDL and it brings, according to the official carrier wording, Visual Voicemail app improvements as well as ISIS app improvements. There might also be some other changes and fixes under the hood though.
The Galaxy S 4 on AT&T is getting version I337UCUAMDL and, while there is no official wording yet, those who installed the over-the-air update are reporting performance improvements. However, until we get an official changelog, we’re being left with guessing whether it’s only our perception of faster operation or it is really the case.
