Strange - maybe it's hardware failure (or loose battery, I don't know). I've only had my N9 for a short time (I think it was just this March that I got it, second hand) and it has been doing well for me. I've tweaked and customized only so little of it, and it's perfect. Yeah, I know there's some quirks with the stock apps and all that. Regardless, the issue you have really is strange.

And hey, man. It's a very old phone (in terms of smartphone progress) already. Support has been cut off. All that's left is that. And besides, I've read an article (forgot the link) which somehow tells the story of how this Harmattan (or at least Nokia MeeGo) came to be, and why the product is a bit half-assed.

I know that feel. Well, the best thing is to change and forget. Props on your GS2. Planning to get something new in the future. But for now, the ingenuity of the Swipe UI keeps me staying. I'll prolly won't change till my N9 is dead.

Good luck with your endeavours.
