I know that sounds like a boneheaded question, so let me clarify it. Is this phone part of the Galaxy series or is it just something that mimics a Galaxy phone? If someone were to ask me if my phone is a Galaxy S2, I'd probably say it's a Galaxy S1.5. With nothing to verify that the Infuse is or is not part of the Galaxy series, I can't say with much confidence. Some websites call this phone the Galaxy S Infuse 4G. But something about that name doesn't sound right, especially because of the way this phone was advertised. Heck, AT&T no longer even sells it. This is my second Infuse. My first one had a premature power button failure and was replaced under warranty almost 4 months ago. This second one (which I found was a refurbished model) is no better. With the latest GB update, I rarely get a GPS signal (and if I do, it's not very reliable), and the phone overheats, freezes, and reboots, all too often. The battery life is terrible as well, draining excessively even when not in use. Wifi disconnects itself after a period of time, even if the Wifi sleep policy is set to Never. Do any of you have the same problems? Do you think the Infuse is struggling in performance due to the limited RAM and now-inferior single core CPU? Why exactly was this phone made? I'm not trying to badmouth Samsung or AT&T; they did a really great job working together to sell this phone, liven up Android, and grab market share. I'm just curious about this phone. My full upgrade eligibility is on 1/1/13 (are AT&T stores open on New Years Day?). For now I qualify for an early iPhone upgrade. What would happen if I walked into an AT&T Device Support Center and told them about all the problems I have with this phone as I mentioned above? Would they consider replacing it with a different Samsung phone (wishful thinking: the Galaxy S3)?
