For this week’s ROM of the week, also check out Insane KitKat ROM for Galaxy S4, available for T-mobile SGH-M919, Canadian, and GT-i9505 variants.
Based on latest T-Mobile Android 4.4.2 KitKat firmware, Insane KitKat ROM brings you a ton of fun customization through its AROMA installer and through various different Xposed modules, which you can also choose which ones to install. (You can watch the latter half of the video above for the AROMA installer choice.)
Insane KitKat ROM is brought to you by XDA user “The Sickness”, part of Deviant Development Team, who also launched the Wicked ROM. Certainly, these guys can make some awesome “sick” ROMs that’s going to wow you with custom boot animations, themes, and more.
Insane KitKat ROM features KNOX and bloatware-free base along with performance enhancements to make your S4 perform faster with better battery life. And yes, since it’s a T-Mobile ROM, you do get Wifi-Calling for those who absolutely cannot live without it. (And yes, if you insert a T-Mobile SIM into GT-i9505 or Canadian S4 with this ROM, you can actually use Wifi-Calling on non-T-Mobile phones too, did you know that? It can come in handy when you are overseas and you want to make international calls at domestic rates.)
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.
