Why will my torch not turn on but button won't turn off

[Android Central Question]

I can't take any photos on my phone even on apps from the app store like Snapchat. Also my phone is permanently saying that the torch is on but there is no illumination from the touch. I've tried everything I can think of even shutting down the phone and it still stays the same.
How do I fix this I need NY camera for my photography project.
