Looking for a fast and stable custom ROM based on Android 5.1.1 for your AT&T or T-Mobile Galaxy S3?
If so, check out the latest Dirty Unicorns ROM, which is an excellent custom ROM based on the latest Android 5.1.1 and brings you a high level of great customizations. Camera works great out of the box (I recommend the Google Camera on Play Store so you get Panorama, Lens Blur, and PhotoSphere modes) along with excellent navigation customization where you can customize all of your buttons (including Home, Back, and Menu buttons with short, long, and double-press) or even disable them altogether and go with soft navigation buttons, which you can also customize with your favorite shortcuts.

The CM12.1 ROM builds are available for all AT&T, T-Mobile, Sprint, Verizon, Canadian, and GT-i9300 Galaxy S3 models. Although these are unofficial builds compiled from CyanogenMod sources, they are actually pretty stable, I haven’t found a single bug yet so far.

For this week’s Sprint Galaxy S3 ROM of the Week, check out Wicked X ROM by XDA user Bilgerryan. I was actually itching to try out this ROM for weeks but hesitated as earlier versions required bootloader update.
Well, the latest version 8 doesn’t require bootloader update (as I believe it’s because KTweaker kernel is used) and have successfully installed on my Sprint S3 with a really old bootloader (I think my last update was ICS).
