Understanding the features of S2 vs 3S3 has been absoultely horrible. We cannot figure out if S2active has fall detection or not. We cannot figure what are the differences between S2 vs S3. Been to Best Buy. Been to Verizon. They are as confused. Horrible marketing and product support from Samsung. If there exists a simple feature list it is hidden for me -- if I can get a link to it that would be great.
