So far the only problem I've faced has been gps issues and I'm using a freshly flashed N9, which is a good indicator. The camera I think may be related to your N9 and some installed app or tweak, as I haven't had any issues with my camera yet. Also the tracker issues arrn't related to fasterN9, I am using it and so far tracker hasn't been an issue. Ask people to flash their N9's then install fasterN9, all of their problems will go away. I have been agressively testing your App and so far it works nothing short of flawless except for gps lock on time. And to test I removed fasterN9 and checked gps to see if it ran and it locked on much quicker with out it, then reinstalled it and gps lock on was slower.
