Phone flashlight not working anymore.

[AC Question]

I use the flashlight on the phone quite a bit and I used it as recent as last night. Last night it was on for quite a bit that as a few minutes it will turn off. Today I tried to turn it on (by chop method and drag down twice from top) and one of the 2 lights flicker on and off but stays off. The other light doesn't turn on at all. Why is that? It's and led light right? I've had this phone for about 8 months.
