Here are 3 Sprint Galaxy S4 custom roms, that I would recommendto you. I have personally used all of these roms and I had no issues with them at all.  I loved it.  Liquidsmooth for some reason gets me the most battery life. I get 3 days battery life with Liquid Smooth. 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, so I’ve just decided to flash a custom rom to have more freedom. **ALL CREDITS GO TO THE DEVS WHO BRING US THESE WONDERFUL ROMS Flash at your own risk, I have a custom rom running and I am loving the experience.  Flashing these will void your warranty. **Nearly all Dev’s recommend that you stay at the Android Welcome screen for 10 minutes after first boot, so that everything settles.

1. Slim Roms [ROM][4.3][Aug 8th] Slim Bean-jfltespr [Alpha 3.1] 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. slim bean rom screenshot features
