For this week’s Galaxy S4 ROM of the Week, check out Mahdi ROM by XDA developer Mahdi786!
Based on latest Android 4.4.4, Mahdi ROM is a new custom AOSP ROM (What is AOSP?) on the market that brings ultimate performance tweaks along with many customizations. You will get a speedy ROM with a custom kernel that has tweaked governor for added performance/battery life.
I know some of you were having trouble with CM11 ROM last week and since CM11 ROMs are usually works in progress, you may see more bugs until they release stable releases. Mahdi ROM releases are stable versions so you probably will get much less bugs if any. Also, Sprint users were having trouble with CM11 last week, Mahdi ROM works flawless on my Sprint S4 as shown in video.
What I really like about Mahdi ROM is speed and performance out of the box without sacrificing battery life. It’s definitely on on my priority list of go-to ROMs right now. I first started using on my Nexus 5 and it was one of the fastest custom ROMs for it. Luckily, Galaxy S4 is actually one of the phones Madhi ROM Team supports right now and you can get it if you have a Qualcomm-based S4 like AT&T, T-Mobile, Sprint, Verizon, Canadian, and GT-i9505.
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.
