Hi, I have a new Captivate; It's the first android phone I've ever had, though I've wanted one for a while. It's amazing, but I have a couple of questions. One: My phone heats up during normal usage. It's not plugged in, but after roughly 3 minutes of Android Market surfing, it gets almost too hot to touch. THen it takes like ten minutes too cool off. I've been laying it on a cooling pad my laptop uses when at home. Is this a problem? Is there any way to fix this? Two: It's running the 2.1 system, but i know 2.2 is coming out. How do i upgrade to 2.2? Will it be in a system update? Or will I have to download it? Three: When I talk on speakerphone, the mic stops picking up my voice after about 5 minutes. I was talking to my girlfriend and suddenly she couldn't hear me. It's not her phone (Samsung FLIGHT) because mine has done this to other people on calls. If I take it off speaker and reactivate speaker immediately it fixes it. What's the deal?
