I bought the epic 4g touch in November, I picked it over the iPhone as I have never been a apple fan. The phone is a lemon and when I mean a lemon nothing works correctly on it. I get a extremely loud buzzing noise that comes from the camera, I have taken it to sprint 5 times for this issue and they look at me like I am stupid and say they can not get the phone to replicate the issue so they tell me they cannon do anything. The phone has also had battery issues where the battery will drain in 4 hours without use, and then the network issues I have. Every time I make a outgoing call or and incoming call I get a message that says network error please check network. I took it to sprint again for this issue and I left it there and all they did was wipe my phone without even telling me so all my apps and information was gone out of the phone. So I went to my last resort and called samsung, I recently sent in the phone and they are waiting to receive it. They guy on the phone the first time I called said that the phone would either be replaced or fixed so I said ok I am ok with that. So I called today and I talked to a lady and she tells me that the phones are never replaced and only fixed which made me really upset because I know this phone is a lemon and its been taken apart numerous times by sprint and I did not pay to have a 600 dollar phone taken apart. I will never get sprint service again or buy a samsung product again unless they resolve my issue. I hate to say it but I wish I would of went with the iPhone you dont usually hear of huge problems like this.
