Update Galaxy Mega 6.3 Sprint L600 to Android 5.1.1 Lollipop ROM. Samsung Galaxy Mega 6.3 Sprint SPH-L600 has an enormous 6.3 inch screen which certainly gives tough competition to Galaxy Note 3, LG L2, Sony Xperia Z Ultra and many high end smartphones. Actually this smartphone is so large that its difficult to carry around. But if you want to experience a tablet like view then this is the phone for you. It comes with the same old Samsung look. It was launched with Android 4.2.2 Jelly Bean but the good news is that Samsung has recently launched an Official Android 4.4.2 KitKat update for this device. I have no idea whether Samsung will launch the latest Android 5.1.1 Lollipop update for this phone or not. But if you have no patience and want to try Android 5.1.1 Lollipop on your Galaxy Mega 6.3 Sprint L600 then you need to flash unofficial custom ROM launched by third party developers. Recently madmangunradio, a recognized member from the XDA community launched the famous and well known Cyanogenmod 12.1 ROM for Galaxy Mega Sprint L600.
