This version of Android 5.0 Lollipop that runs with TouchWiz on top will cater to the SM-G900P, which so happens to be the Samsung Galaxy S5 which is made available by the folks over at Sprint. Do bear in mind that this particular firmware version will not run properly on other versions of the smartphone, so it might not be a prudent idea to go against the grain.
Being an unofficial build that is early in the game would certainly come with its fair share of niggling issues, including a slew of bugs and complications, but the so called “holy trinity” of a smartphone – calls, messaging, and internet, happen to be working just fine.
