So I brought my Captivate in with an overheating battery. My battery status app said it was at 153 degrees F and I couldn't get it to charge without getting up in the 140s to 150s within 10 minutes. As soon as the AT&T tech saw that and tested it for 30 seconds, he said he'll have to replace the whole thing because there is likely permanent damage done to the phone already. Long story short I didn't like the idea, especially since my captivate has been trouble-free since august without ever experiencing gps or shutdown issues before (only lag, but I could deal with that). Luckily the GPS works great and I haven't had any shutdown issues as of 4 hours in. Problem is now this new one doesn't like my home network. It connected fine when I tested it in the ATT store, but at home my phone shows the wifi alongside 3g, but fails to access the internet. What happened, the other captivate was just fine, not a single issue with wifi except for a random loss of connection once a week or so. What can I do to try and fix it, I don't want to have to drive an hour to the service department again tomorrow just to get a phone that may have a GPS issue instead. What do I do? Note the phone has 2.1 JH7. I am currently waiting for the new battery to fully charge before Kies allows the upgrade to froyo, but I'm not sure if that will fix the problem.
