If for some reason you are not satisfied with the stock camera of your device — try Camera Z. It features a very fast, minimal interface, easy operation with gestures and lots of filters that you can apply before filming, in real time. Filters in the camera do a lot, but if you want more — you can contact the corporate store and download additional solutions. There is also a favorite of many, HDR mode and a simple image editor. And the program includes proprietary codecs, so it works adequately on third-party firmware.
