I have had many of the same issues with my evo. I could have upgraded in January and though about getting the one m7. But I wanted to see what HTC's new flagship was going to be. I'm sooo glad I waited. The one m8 is fantastic! Every issue that I had with the old phone is gone. Most of the issues with sprint's network are gone too. The only issues that I have are related to the continuing build out of the network. 4g speeds have improved, (evo was 1-3 down , m8 6-11 down) staying connected to lte has improved. As far as the camera goes, I was worried about the reviews, but I have been pleasantly surprised. Remember, it takes a while to build something from the ground up. As far as HTC , the new one m8 has made me love my phone all over again.
