An official Samsung Android 5.1 update for Sprint Galaxy S4 is as good as already ruled out, both because of S4’s age and Samsung’s lethargic approach to updates. The Samsung 5.1 update is expected to arrive on company’s S6, S5 Note 4 and Note 3 in coming 2-3 months, but S4 users look to have fallen behind, no longer in the plans.

Thankfully though, there will be lots of custom ROMs that can be relied upon as far as Android 5.1 update for Sprint Galaxy S4 is concerned. We’ll get CM12.1 for sure, but right now, we’ve got the GamerROM that’s based on none other than CM12.1 and is already available for installation. And it’s also available for Verizon S4 and T-Mobile S4.

Being based on CM12.1 which is turn is based on AOSP, the GamerROM features an incredibly beautiful pure Android Lollipop interface, ditching the Samsung’s dirty TouchWiz UI for good. The Lollipop UI alone is worth the efforts of installing a custom ROM, let alone additional features of Android 5.1 and CM12.1.

Both CM12.1 and GamerROM are far from fully stable as of now, and both are in early stages of development. But don’t worry, save for video recording, everything else is said to be working fine.

And in any case, if you want to go back to official Samsung firmware for your Sprint Galaxy S4, you can do so pretty easily — a simple firmware flash using Odin software is all it takes to remove custom ROM, custom recovery and root, all in one shot, and restoring the phone back to stock, Samsung firmware.


Note: As you already know, it’s not an official Samsung Android 5.1 update for Sprint Galaxy S4, so expect few kinks at some corners of the ROM that are yet to be fixed by the team. Any major bugs will be reported below.

Bugs
  • Video recording
Downloads

Download the ROM file in .zip format from the source development page here, where you could also keep a tab on updates for the ROM, and any current issues with the ROM with fixes, if any, available. No need to download the Gapps separately as this ROM contains them already but flashes separately than ROM to be in line with Google’s policies, while saving you some labor work.

Supported devices
  • Sprint Samsung Galaxy S4, model no. SPH-L720
  • Don’t try on any other Galaxy series set or other device of Samsung or any other company
