Help Front Facing Camera Problems


my incredible s does not detect my front facing camera
whenever i try to take a picture from the stock camera app, i click it and try to switch it to secondary camera, it just stays on the back camera and does not switch to the front camera (the mp and quality decreases tho i assume that is the setup for the secondary camera). is this a software or hardware problem and how do i fix this? Thanks for your help guys
sad to say mine is facing the same problem.. my incredible s front camera isnt working, everytime i switch to the front ( secondary ) camera, it hangs there.. and blackout in the end.. i wish to know why and how to fix it.. T-T
