Re:
I can suggest you "One Touch One Touch Flashlight (Users Camera Light)". It's very powerful and also cost-efficient. The brightest light when and where you need it. The original Blackberry app to use Blackberry’s video light source rather than the low-light LED screen employed by other flashlight apps. Flashlight uses less power. It stays on until you turn it off. One-touch on/off icon lets you see trouble before it becomes trouble.
