For those of you haven’t heard, Android 4.4.3 is already out since last week and if you want to experience the latest Android 4.4.3 with full root, you can do so with the latest CM11 (CyanogenMod) ROM!
And no, you don’t have to wait for official firmwares to come out from Samsung, which will probably take weeks or months more from now on.
With Android 4.4.3, you will be able to experience 20-30% improvement in performance and also near 10-15% better battery life. It’s an “amazing” upgrade as you get much better performance as shown in my Antutu benchmarks (see video).
Other than that, the latest CM11 ROM also brings new theme engine. Similar to MIUI ROMs, you can now get a bunch of great themes along with ability to choose sections of theme you want to apply. Also, the latest Google Camera works flawless, allowing you to experience the latest and best AOSP camera along with full PhotoSphere/Panorama features.
All CM11 ROMs now have one file for installation on all Qualcomm-based Galaxy S4 models (all models except GT-i9500), you should be able to get it installed so long as you have LTE on your Galaxy S4. This is what’s hot “right now” so definitely give the CM11 ROM a try this week(end) and do let me know what you think!
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.
