Since most people that own a Galaxy S III are probably stuck in a contract with at least 1 year remaining, it’s good to know that Samsung plans on bringing most of the new Galaxy S 4 features to the Galaxy S III. I say “most” because some features such as anything regarding the IR blaster won’t make it since the GSIII lacks an IR blaster. So this means that features such as AirView, Smart Pause, Optical Reader, Group Play, Drama Shot, Photo Eraser, Sound and Shot, Cinema Photo, Dual Shot, Dual Recording, ChatON Video Chatting, ChatON Screen Sharing, S Translator, Adapt Display, and S Health will probably make it to your phone. I presume they will be part of the Android 4.2.2 update. As to when that will happen, no word, but you know how that goes with all the carrier testing. I wouldn’t expect carrier branded devices to approve the update until the end of the summer, but that’s just my opinion.
So there really isn’t a need to worry about upgrading, but if you’re still on the fence, you can check out our hands on video as well as Samsung’s overview video on the Next Big Thing.
