For this week’s ROM of the week for AT&T, T-Mobile, and Verizon Galaxy S3, check out the latest version of Synergy ROM. Previously it was a bit buggy I admit(on non-Verizon versions) but the latest version I tested works quite well with full multi-window on AT&T, T-Mobile, and Verizon Galaxy S3s. It’s supposed to work also on Sprint Galaxy S3 but I have had some troubles as shown in video overview.
I know there’s currently few ROMs that offer you full multi-window on the AT&T and T-Mobile Galaxy S3 but the Synergy ROM is one of the few that do and hence a great option for those of you on AT&T and T-Mobile. Also, you do have to flash an extra contacts fix file for AT&T or T-Mobile otherwise you will get a force close error with contacts and not able to make calls (I found out) but after flashing the patch, I’ve had zero problems since then, everything working pretty darn smooth.
Synergy ROM does offer overclocking up to 1.9Ghz but I do recommend around 1.6-1.78Ghz OC for optimal performance and battery life.
Wifi tethering works with its on-board Wifi Tether Treve app, just set SSID and Wifi Encryption and you are set to go.
Also Synergy ROM does offer both Android 4.2 Photo Sphere Camera and Note 2 Camera, something I really love about Android 4.1.2 ROMs.
If you really need multi-window, overclocking, and two cameras on your AT&T, T-Mobile, or Verizon Galaxy S3, give the latest Synergy ROM a try and let me know what you think. (Don’t forget to rate the ROM at bottom of this post after trying!)
Overall, I have to hand it to the Synergy ROM developers who are the first to bring fully-working, stable multi-window to AT&T and T-Mobile by porting Verizon ROM, thanks again guys and don’t forget to donate to these devs.
