UPDATE: There’s a newer version r443, please CLICK HERE to see the latest version!!!

Synergy Team has just released their “r420” release of their Synergy ROM. The latest version of Synergy ROM comes upgrade with Android 4.1.2 base, and works for all AT&T, T-Mobile, Sprint, and Verizon out of the box (test by myself). This is probably the best multi-carrier ROM for the dual-core Galaxy S3s right now and Synergy Team has finally done it, made a ROM that works for all 4 major carriers with 2 cameras (Android 4.2 PhotoSphere and Note 2 camera with Slow Motion/Time Lapse) working flawless and transparent multi-window bar enabled for all apps.

For Sprint or Verizon users, this might not sound like a big deal but for AT&T and T-Mobile users, I think this is a great deal considering there’s not that many ROMs with multi-window support working flawless out of the box.

The latest version also adds floating point keyboard for multi-window (just like Note 2), volume key shutter, 23 Lidroid Quick toggles, and more.

I am very impressed with the latest Synergy ROM and if you haven’t tried Synergy ROM r420, definitely give it a try this week(end) and do let me know what you think!
