You may find another smartphone that has slicker features, but you won't find one that's rated higher than the Samsung Galaxy S4.
Consumer Reports shows this phone in the top spot for ALL carriers. That's one of the reasons Why I Picked the Samsung Galaxy S4 Smartphone.
And regardless of whether you use AT&T, Sprint, or Verizon Wireless, the least expensive phones show up on Amazon.
Just as an example, here's the Verizon Wireless version of the Samsung Galaxy S4 on Amazon. Even if I upgraded my plan to this phone, Verizon would charge $199 just for the phone. Amazon is just plain cheaper!
