Android 5.1.1 + Root for Galaxy S4 GT-i9500! [Euphoria OS]


For this week’s Galaxy S4 GT-i9500 ROM of the Week, check out the latest Euphoria OS ROM.

Based on latest Android 5.1.1, the Euphoria OS ROM allow you to enjoy the best of latest Android 5.1.1, which comes with added stability, fast performance, and great battery life.  The ROM itself is faster than any other custom ROM I’ve tried so far as far as the UI and how fast apps run without any overclocking.  You can really feel the difference when running Android 5.1.1.

Other nifty feature include unlocked tethering, long-press back button to kill apps, built-in Superuser, and all the standard features from all-new CM12 ROM including AudioFX app, CM themes, and lots more.

Although there’s no official CM12.1 builds for the GT-i9500 yet, the Euphoria OS will allow you to basically experience all of CM12.1 and this ROM has been optimized specifically for the GT-i9500 so you won’t find bugs. So far, it’s running very well on my GT-i9500 with great battery life so definitely check this ROM out this week(end) and do let me know what you think!
