I've had several iterations of Samsung phones, the S3 was my first smartphone, bought the S4 and now recently purchased the S5. After 2 months my screen stopped responding, as in the display itself was fine but the phone would no longer respond to touch. No big drops or anything so 99% sure it was a defect with the phone. I tried to get Samsung to fix it and they went out of their way to avoid any warranty work. After a short chat with Amazon they sent a replacement, 3 days later I had a new phone. This experience soured me slightly on Samsung, but I still think they make the best value smartphones out there, however I'm 100% sold on Amazon based on their reaction, will be a Prime customer for life. I was a little wary of buying a seemingly discounted smartphone via amazon and not Verizon or directly from Samsung, turned out to be a good decision.
