I only have charging issues when I use my chargers/cables from my GalaxyS3. But I had that before I rooted even.
So I wonder if people are using chargers or cables that aren't the provided white stock one.
Also, even with the white stock one SOME pc connections don't put out enough amperage to charge the GN2.

Don't forget 5) PC not recognizing phone for file transfers.
Many have report this, me included.
Yes, I have this "problem" also, however I did not list it simply because if I connect as camera it gives me all the same functionality I would use otherwise which makes this pretty hard to think of as a debilitating flaw. In reality all you have to do is pull down your notification bar and click the button that says "connect as camera" and everything works perfectly again. I didn't even have to read to figure this out. Just a little basic playing/investigating on my part yielded the answer. I would say this is a very forgivable and extremely minor inconvenience in light of all the many other perks this Rom supplies.
I think some, probably not all, but some of peoples problems come from skipping steps or dirty flashing. A clean wipe and fresh install is a bit of a pain, but I would rather take a few extra minutes to set up my phone on a clean working rom than spend "x" amount of hours trying to figure out problems on an incorrectly or hastily installed rom.
When the Op and everyone here keep repeating the mantra, "read, read, and read some more" I can speak from experience that the benefits are two fold in that:
1) you will probably find the answer to the question you were going to ask anyway and;
2) you almost definately find answers to questions that didn't even know you had to ask yet making situations you run into in the future less likely to be handled incorrectly because you will already know what to do.
I'm not saying that you haven't read or that you are installing the rom incorrectly. This isn't really pointed at you personally, I'm just using the opportunity of your question to make these observations in general for everyone.
