The Galaxy S4 is a very powerful smartphone with lots of features and amazing specs. However, when it comes to performance with the stock TouchWiz, the device falls short. If you are not happy with the way your phone performs or you do not like the look and feel of its user interface or are irritated to see the bloat apps in its app drawer, going for a custom ROM might prove a wise decision.

Custom ROMs are developed from user’s point of view and aim at giving you the best possible performance and better battery-life out of you your Android device. If you are new to Android or are busy enough not to spend time on searching for good ROMs or you are just confused about which one to go with, we are here to help you with that.

Before we list some of the best custom ROMs, let us clarify it first that our selection of best custom ROMs for AT&T Galaxy S4 SGH-I337 and Canadian SGH-I337M  is based on the following standards:

  • Speed and Performance
  • Stability
  • Features offered by the ROM
  • Battery-life
  • A balance between stock TW and AOSP based ROMs

Another thing that is worth mentioning here is that the ROMs have been listed in no particular order. That is to say, the ROM listed at number 1 position is not necessarily the best of all.

1. GoldenEye

Developer: iB4STiD


ROM Review:

GoledenEye is a Samsung TouchWiz based ROM that offers all the stock features you enjoy on your phone. The ROM is compatible with both, the US (I337) and Canadian (I337M) version of AT&T S4. It is based on the latest Android 4.2.2 XXUBMH1 firmware for GT-I9505 and therefore it has features like the Apps to SD, semi-transparent statusbar, improved camera picture quality. As seen on most custom ROMs, GoldenEye has extended reboot menu and supports APN editing. To give you a cleaner app drawer that is devoid of superfluous apps, most bloat apps have been removed, and thus you get more free RAM on your device. Besides, the ROM features various mods and performance tweaks to have better stability and speed.

If you would like to stick with the stock ROM so that you can enjoy all default features with better performance and battery backup, GoldenEye might be a good ROM worth giving a shot.


Special Notes:

For AT&T US S4:

Before installing GoldenEye on your AT&T Galaxy S4 (GT-I337/M), make sure that your phone has UCUAMDL as baseband. You can check this from Settings> More> About. In case it is different, install the following firmware file using ODIN first:

2. KangaBean

Developer: iB4STiD


ROM Review:

TouchWiz being terrible in user experience, many Galaxy users turn to so AOSP based ROM for better performance. The flavor of stock Android really tastes well! If you want to enjoy it on your AT&T Galaxy S4, what could be better than the original Android 4.3 ROM from the Google Edition Galaxy S4? Less bloats, less weight and clean Holo UI, and speedy experience combine together to give you overwhelming experience when they are supported by the whopping specification of our S4.

KangaBean is based on the Google Edition Android 4.3 ROM and thus it lets you enjoy the latest Android on your S4. As some extra pudding on the top, the ROM also comes pre-injected with various system mods and tweaks.

Download and install the ROM zip file and then flash one of the Faux Kernels from below depending on your device model.

3. Infamous S4™ ROM

Developer: Jamison904


ROM Review:

Infamous S4™  might not be a very famous ROM, yet it is a deserving candidate to be included in an article like this. Again, here is a TouchWiz based ROM that has a highly tweaked kernel for amazing performance. The ROM features a host of mods and optimizations. Infamous S4™ is powered by 3Minit framework and thus it pack unlimited options to theme and play with internal System UI settings of your device. However, to be able to get those customization options, you will have to install the 3Minit Settings S4 app from the Play Store.

Its performance is marked by proficiency and stability. Tweaks like turbo six-sigma like tweaks are very dexterous and intuitive as it shows all the ongoing system activities with transparency. Ad for battery-life, Infamous S4™ is probably the best ROM for the Galaxy S4 SGH-I337 and Canadian SGH-I337M.

  1. How about Wanamlite, by far it’s the best for battery life of any custom roms. It give you some rom control and keeps the UI and start up screens nearly completely stock, it’s one of the most solid roms I have used on this device or any other device I have had in the past. Also in my experience, while I hate touch wiz it almost always has better battery life then any of the aosp roms I don’t know why?
