I am very disappointed in my replacement phone. My GS4 started resetting itself after the update and Verizon did a factory reset. I still had to get a replacement phone. I was very disappointed when I was sent a certified replacement phone. I spent $300 dollars on my phone and I feel as though when a phone is replaced under the warranty it should be new as well. I understand if you send out a refurbished or replacement phone on a damaged phone. But this phone is a warranty replacement. Not to mention the phone is overheating and the old one didn't.
