Power Button FlashLight /Torch

Power Button FlashLight is an app that lets you turn on the flashlight on your Android by using the power button. You just have to press the button three times for the flashlight to turn on.

In the settings you can select how fast you have to press the button. By default, you have to press it three times in three seconds or less, but you can adjust this to your preference. However, if you want to use this same method to turn the flashlight off, you have to purchase the complete version of the app. Other options let you turn it on/off by shaking the device, or make it vibrate each time it turns on.

Power Button FlashLight is a simple but useful app that gives you an alternate way to turn on your flashlight. That said, it might actually not be a great idea to press the power button so many times, but it's up to you.
