    Camera and flash sounds like a hardware issue.
    As for battery, since the phone could be almost 4 years old, if it still has its original battery it's probably nearing the end of its useful life. Check here to find out how many cycles your battery has had and what sort of charge it holds. Check iPad iPhone battery charge cycle count without jailbreaking

    You can test your battery this way to see if it needs replacing.
    Write down your usage and standby time, press the sleep/wake button (or lock button, as some call it) to put the device to sleep, and set the device down for five minutes. When you come back, take note of the change in time. If your device is sleeping properly, then the Standby time should have increased by five minutes and your Usage time by <1 minute . If your Usage time rises by more than one minute, you have a drain problem. Something is keeping your device from sleeping properly, significantly shortening the time it will last.

    Seriously. What do you expect us to say? I mean you've stated that you bought a "used" iPhone 4S and its camera and flash do not work. Those things will have to be repaired obviously. As for the battery, your device is 4 years old and depending on how the former owner(s) used it, you may need to replace it.
