Flashlight Always on. How to disable??

[darkwolfx]

Hello guys.

My phone fell into the water, and well, I removed battery, left it drying up for about a week, and afterwards, everything works fine, for just except one thing...the flashlight is always on, but seems like it's dim not the way it should be.
Although it works if I activate it, take a picture or use it as a torch, when not in use, instead of being off, it looks very dim, so it is there.

My question was if you guys knew how to disable it from being on and just deactivate it for good.

I would appreciate any ideas, thanks!
