Android 4.1 for AT&T Galaxy S3: Install ParanoidAndroid ROM with Special Hybrid UI [Jelly Bean]

ADVERTISEMENT

The AT&T Galaxy S3 saw the release of a Jelly Bean Android 4.1 ROM for it a few days ago with the official CyanogenMod 10 ROM, and now there’s another Jelly Bean ROM out for the device, though it’s not like any other ROM out there.

ParanoidAndroid ROM based on Jelly Bean has been released for the AT&T Galaxy S3, which brings along a phone and tablet hybrid UI. What that means that instead of the usual interface found on Android phones, you get a tablet-based UI with two column menus, a notification menu at the bottom of the screen, and many more such tablet interface-inspired changes. It’s not a tablet interface, but a hybrid of both phone and tablet interfaces to make effective use of the large screen.

Keep in mind that the ROM is currently a work in progress and has a couple of issues present, which are mentioned below (quoted from developer):

Known Issues:

  • Camera Force Close i.e doesn’t work
  • Bluetooth A2DP (normal Bluetooth works)

So let’s take a look at how the ROM can be installed on the AT&T Galaxy S3.
