We've been focusing our attention to the Galaxy S6 and Galaxy S6 edge a lot lately because the two are hot subjects of reviews and stress tests but we haven't forgotten about the Samsung Galaxy S4. The 2013 flagship can still get the sweet mobile OS update from AT&T. This was one of those many expected things since the Android Lollipop for the Galaxy S4 LTE-A is ready for download. Even the Russians know their Galaxy S4 is getting a taste of Lollipop. This was after the official-looking Android Lollipop for the Galaxy S4 was leaked.
