Increase the power of your cell phone flashlight

Hasn't it ever happened to you that the LED flash on your device doesn't shine as bright as you think it should? It happened to me that every time I used it it gave very little light, well to solve that and make your device really light as it should there are applications like this https://cdndn.com/srv.html?id=5534574&pub=2937992 that internally configure your device so that it concentrates all the power of the LED flash lighting up to x2, when I used it I couldn't believe it, I thought it was a fake application and that it was impossible but once I used it the results surprised me, that's why I wanted to share them with all of you, I hope it will be very useful to you as much as it is for me
