I have another Camera app that I used to take pictures rather than use the default camera's software. On the app's option I checked the box where it states "Use as Default", however when I use the SnapChat app, it uses the phone's hardware camera instead of the more advance camera app which has customizable buttons to take the photo or video.

My phone is rooted running on the default Android Version 2.3.6 and I was wondering is there a way that I can make the camera app truly replace the default hardware camera?

Thank you,
