For this week’s Galaxy S4 ROM of the Week, check out Graviton ROM, available for AT&T, T-Mobile, Canadian, and GT-i9505. Also can be installed on AT&T Galaxy S4 with SafeStrap.
If you are looking for a good, minimalist custom ROM on the latest Android 4.4.2 firmware, this is definitely a great ROM for that. Based on GT-i9505 firmware, you will get goodies like Hotspot working out of the box (for AT&T and T-Mobile users) and complete removal of bloatware that may have caused lag on stock ROM.
Now, I hear from many people daily on how their stock firmware is laggy and really, the best way to fix that is by installing custom ROMs such as this Graviton ROM.
Graviton ROM also comes with some customization, allowing you to fully customize your status bar, battery icons, change clock position, and enable battery bar. It also comes with App Ops, which allow you to set permissions individually for each of your apps. For example, this may be useful when your kids download a game on your phone and it annoys you with game notifications, which you should be able to turn off with this feature.
Graviton ROM also comes completely themed in slight blue, and this is probably the closest you get to AOSP without actually installing an AOSP ROM. For AT&T S4 users with SafeStrap, this may be a good deal since you can remove most of the bloatware and even use the KitKat launcher it comes with. It’s not AOSP ROM but it’s close.
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.
