Something to remember: every product will have a few with some defect or other, and (for those where it's a relevant consideration) some where a setting or something gets garbled and has to be redone, that sort of thing. Message boards are going to tend to collect the stories of those who are having problems, so it looks like a lot no matter how few it is. This is especially true for sites like this that are good for advice on troubleshooting and workarounds.
Meanwhile, the majority who are having no problems have no reason to complain about their phones or ask advice on fixing them, so you pretty much only see comments from the few who happen to come across someone else's trouble and say "funny, mine doesn't do that."
In short, don't worry about it.
