"Truly, "The Next Big Thing.""4.0 starson by littleafternoon
Pros: Lightning-fast Snapdragon 600 processor. Super fast and super responsive interface. 13-megapixel camera with its abundances on features. Full 1080p display. Software features are also pretty neat. Plastic case provides better signal and GPS lock.
Cons: Design feels stale, not much different from the Note II, and the eye tracking technology feels a bit gimmicky; not as responsive.
Summary: All in all, the Samsung Galaxy S4 is great with it's full 1080p AMOLED display and great battery life, as well as small improvements on the touch wiz over Android 4.2. However, things like the new tabbed Settings app feels like a downgrade with no swipe interface. Software features are pretty awesome, but are just waiting to happen in the next firmware update for most other Android phones. In the end, I would say it's worth the upgrade from the S3 if you're looking for a better camera and/or full HD display.
