Will my iphone flashlight burn/die out?

My iphone fell on the carpet so no damage but my cameras won't work, the flashlight turned on and i turned off my phone then on now the light is smaller than it was before does this mean when it dies out my cameras will work again?

That sounds like you knocked something loose. But the flashlights on the iPhone are the same lights on the screen, they recharge just like the rest of the phone. So under normal circumstances, no.
