I'm not sure what their problem is, but it seems like Samsung certainly has a big problem with their Android phones on CDMA networks. The pattern seems to run with the radio having problems. It started with the Moment where the phone's radio would constantly have dropped connections and lock-ups, and the phone going into Airplane mode randomly. The Intercept has it's fair share of radio issues as well, however, I can't list the exact problems as I've never owned one. Now, with the Epic, I'm afraid that this pattern continues. After a lot of research, tinkering, and just general speculation, I think that what's happened is that Samsung has "jimmy-rigged" GSM radios to work with CDMA networks. This would explain the problems that are seen in the Moment, Intercept, and now the Epic 4G's data upload cap, and maybe even the time without a signal problem as the phone could be searching for GSM networks. It even show's that the Epic's preferred network in the advanced settings is WCDMA -- which IS a GSM network. Don't get me wrong, i love my Epic 4G, but I have a lot of problems with the damn radio. Calls are great no matter what the signal bars show, but the problem comes with the 3G data. My phone will be at full signal in my house, and then suddenly drop down to no signal for no apparent reason. Sometimes when I run a speed test, I get speeds as slow as 30-50kbps/sec download which is absolutely horrendous. The good news is this appears to be a software problem and can be fixed if Samsung wants. Let's hope they do, as being a previous Moment owner this kind of issue is very disheartening. Before you think about flaming -- Please realize that this just speculation, and was hoping for some your input and/or experiences with the same issues that I'm having.
