best custom roms At&t Galaxy S4

Here is a list of the top best roms for the Galaxy S4 ATT.  AOSP (Android Original Source Project) and stock based.  Flashing a new custom rom is a good idea in my opinion, because a lot of the times the Dev’s that cook up these roms actually bring in new Android features straight from new Google AOSP code itself or from leaks.  The default Samsung Touchwiz rom is just android with Samsungs interface put on top of it and loaded with some bloat apps that eat up battery and are unnecessary.


Flash at your own risk, I have a custom rom running and I am loving the experience.  Flashing these will void your warranty. Make sure to flash only rom that is specific to your device. Devices are given nicknames.

These roms are also said to be compatible with Canadian Bell, Rogers, Telus,  and Virgin. (Not CDMA I believe).

**Nearly all Dev’s recommend that you stay at the Android Welcome screen after first boot, so that everything settles.

1. Slim Roms

AOSP, Slim Bean jflteatt ,

Original Slim Features:

  1. The Real Dark Slim
  2. Notification drawer Shortcuts
  3. Full hardware key rebinding!
  4. Keyboard rotation
  5. SlimCenter

Before Liquid smooth, I enjoyed using Slim Rom as it is the only rom that comes with 240 or 260 pixel density, so your screen will look much bigger than it actually.  One of my friends was wondering why my Galaxy S4 had a bigger screen compared to hers.  I jokingly told her “It’s a special edition”.  With a lowered pixel density, things look great and super high def.

2.  Original LiquidSmooth

I absolutely love this one, it gets way better battery life than Slim Rom.  But I can only speak for Liquid Smooth on T-Mobile Galaxy S4 as I can’t use AT&T version since I have a T-Mobile M919 rom.  With Liquidsmooth, I can go 3 days without recharging, but that is with Gmail autosync turned off and using the phone as normal with data enabled (No games or any cpu intensive tasks).

4.  Google Edition 4.3 Rom


  • Deodexed
  • Zip-aligned
  • Rooted
  • Auto-loki
  • Removed all apps available in the Play Store except for Google Keyboard and Google+
  • Removed some Samsung bloat
  • Play Store 4.3.10
  • Google+
  • Google Wallet works out-of-the-box


  • This ROM uses a Sprint (L720) branded build.prop to make Wallet work out-of-the-box. There should be no problems with using a different branding from the phone you actually have. If you want to rebrand it to AT&T (I337) or Canadian (I337M), flash the attached build.prop but Wallet may stop working.
