Looking for a great Android 5.1.1 ROM with fast performance, great battery and excellent level of customization? Check out the latest Dirty Unicorns ROM, available for all Qualcomm-based variants of Galaxy S4 including AT&T, T-Mobile, Sprint, US Cellular, Verizon, and GT-i9505. (Not available for GT-i9500 sorry!)
*Note – For AT&T or Verizon, you must have unlocked bootloader to install this ROM!
*Note 2 – The video overview is for Galaxy S3 but 99% of the features are the same as the one for S4.
Since this ROM is identical to the Galaxy S3 version, here’s an except of its features:
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.
Of course, that’s not all and you will be able to fully customize your status bar, add weather widgets on lockscreen/status bar, change LCD density, and much more. All of these tweaks can be found under Dirty Tweaks in Settings.
What is a Custom ROM?
A custom ROM is a custom, modified operating system that you can install on your Android device. Basically it's like installing Windows OS on a Macbook. By installing a custom ROM, you can bypass stock factory settings like locked hotspot tether, install new Android versions early, or even convert your phone into another OS.
With a custom ROM, you can really maximize the capabilities of your smartphone by adding custom features that have been developed by open source developers.
