FxCamera
FxCamera is a straight shooter; it does what it says and does it to its maximum potential. If you need any proof, just check out the download numbers, which should speak for themselves.
Created by ymst, the developer might got close to a fail when it comes to his previous creation, but has scored gold with FxCamera, a brilliant job to say the least. Personally, this is one of those few apps that gel into the whole Android ecosystem without breaking a sweat.
