Though it's been little more than a week since the Galaxy S4 hit T-Mobile airwaves, the carrier's showing the newest member of its smartphone family some love with an incremental update. Rolling out OTA and via Samsung's Kies software, the focus of the patch (version M919UVUAMDB) seems to be on T-Mobile's pre-installed applications, rather than the system software as a whole.


The Visual Voicemail and ISIS apps are set to receive "improvements," whatever that means. Still, it's good to see T-Mobile minimizing bloat while trying to maintain a good user experience so soon after the Galaxy S4's release. The effort is even more impressive when you consider that the GS4 isn't even available on a particular carrier yet.

Owners of T-Mobile's Galaxy S4 can begin looking for the update May 7th. If you notice any other bug fixes or additions this firmware brings, feel free to send us a tip.

    Hello, friends! good news! good news! Now, the most popular S3 Galaxy i9300 Phone only € 99.99. I purchased this wonderful phone, everything perfect. this is my first purchase on this site, bought non-brand phone. but I am proud to say, this is the most successful deal, the most satisfied online shopping. you maybe not buy a non-branded phone, however I can prove: this 4.7 inch Android 4.1 i9300 Smartphone (have a T-Mobile Samsung Galaxy S3) is amazing! much better than real Samsung phone. my all friends are using it, the big screen, ultra-slim smartphone, 8MP. I am also very envious of them, I always want to buy this phone, but too expensive in real store. but so lucky for me, I met this perfect phone on a forum, I bought it without any hesitation. therefor prove my choice is right, it is really really perfect! unprecedented good. no matter I say how many praise, you still can't feel its highest quality and best function. when you get it, use it, you have the same experience like me. so what are you hesitation? 80% off now. you only spend lowest price €99.99, spend less, enjoy more. don't miss. really perfect: http://zzxir.com726

    In the case included the typical, mobile, charger and headphones, all very well packed and in perfect condition. the battery was tinkering for one hour. after testing an hour, I can say that the phone's fluidity is very good, had previously passed through my hands another terminal single core Chinese with a processor, and this with the mtk 6577 to 1.2 GHrz is an 8MP camera. a large screen high definition. very fast, in perfect condition, better than I expected. Now, check the durability, which scares me, but looks great. Jelly Bean Android 4.1.1. You can set in Spanish and can disable all. Wonderful, through my own experience. very popular. the cheapest in Spain. highest discount now, I decide to buy another phone, as a birthday gift to my brother. € 99.99. a funny thing: one of my friends bought eight phones. he will send these phones to his family. filial piety. I really highly recommend it to everyone. very credible. very worth
