I dropped my phone and next thing the camera wont work. When I try to go on my camera, it is just black and slow and the shutter won't take a picture or anything. I know the front camera works however it takes a while and hardly ever goes to the front camera. Meaning when I try to switch it, it doesn't go and its rare that it does. Along with this, when I go on snapchat, when I try switching the cameras, its either too slow, stays black or it doesn't go at all. How can I fix this? Don't say for me to get a new phone, I'm waiting for the new iPhone to come out. Do I need to replace the back camera and would that fix everything including my snapchat?
