I have two problems with my Galaxy...it's a year old, but it's had some problems for about six months. I was staying in a place with pretty bad reception (as in, even the TV kept randomly not receiving a signal) and I'm pretty sure the problem all started then.
Since then, my phone has had horrible battery drain when I have 3G turned on. I could happily have 3G turned on all the time before December (phone bought June), but after that, the phone will drain even when it is not actually being used (last night I tried turning 3G on and just leaving it and it dropped from around 90% to 13% in about three hours - nothing downloaded) and it will get quite warm (around 40 degrees from 23-ish). When I have it on and it's in my bag, I can actually feel that it has warmed up the stuff around it (obviously, I don't have it on unless I actually forget to turn it off after looking something up). No one has been able to suggest anything to stop this problem. Every time I have to look something up, I have to go into Settings to turn the 3G data on, then look up whatever I need and go back in and turn it off. Might seem like a small thing, but it's super annoying - particularly when it used to work! I've tried turning it off and back on, nothing. I've tried turning 3G on and draining it until it turns off, nothing. I've tried using the 3G in areas with excellent reception, but it still drains.
Also, I haven't been able to send or receive picture messages for a while. I have no idea when this problem started...it was working last year (although pictures were always received as a video of a few seconds of the same image?), but whenever I try to send picture messages to people, it just constantly says 'Sending' at the bottom of the message (I have one in my messages that was sent on 3 Jun, it has the picture on it, but still says Sending at the bottom) and when someone sends me a message, it just says 'Downloading'. I have one that was sent on 4th or 5th of April that says:
Message size: 255KB
Expires: 16:43, 6 Apr
Are these problems with my phone provider (Virgin) or my phone? I've never had problems with Virgin reception and I've been with them for 6+ years.
I was looking at upgrading my firmware from 2.2, but I really don't want to lose data on my phone (or have to back up and restore when logs etc can't be restored).
