We've already seen Samsung's current and former flagships run Android 5.0 Lollipop with TouchWiz atop - the Samsung Galaxy S5 and Galaxy S4, respectively - in a couple of video previews, not to mention the numerous screenshots that are already available for our viewing pleasure. Although the official firmwares will certainly not land on said devices very soon, it was just a matter of time before someone leaked the Lollipop firmware in question to the vast hordes of fans of these devices.
Well, we have not yet caught a sniff of the TouchWiz-esque variation of Android 5.0 Lollipop for the Galaxy S4, but fortunately for the fans of the Galaxy S5, the Lollipop firmware for one of the versions of the device - the Sprint one (SM-G900P) - has been just leaked at XDA. That said, it should be mentioned that this firmware won't run on run properly on any other version of the handset.
Being the early, unofficial build it is, the firmware surely flaunts a surplus of bugs and issues, but then again, some of the most important functionalities (calls, messaging, and internet) are reportedly working as intended. If you are eager to jump on the Lollipop bandwagon, head on to the source link, backup all of your data, and make sure you know exactly what you're about to do.
