If you have ROOT privileges on the phone you can access a series of quite particular features. One of the most curious is the possibility of using the different physical buttons with which a device has to, for example, turn on the phone's flashlight, or what is the same, the LED flash that most Android phones have.
But what if one did not have a custom ROM or ROOT privileges, possibly they could think that they could not access this feature, although thanks to the Power Button Flashlight app they will have the aforementioned functionality, since this application does not need ROOT. This app is about allow to use the power button to activate the flashlight of the telephone.
As simple as pressing the power button
Now you will think about how you will have to touch the power button to activate the phone's flashlight, and it is quite simple, since the default configuration of the app allows by 3 quick keystrokes to activate. And by the time the screen is on, you'll need to press the power button up to 4 times to achieve the same effect.
Paid version with extra functionality
Now that you have your phone's flashlight on, you'll want to know how it turns off, and the easiest thing would be to think that tapping 3 or 4 times will deactivate it, but for this the app's payment model enters. In the free one you will have to access the app to be able to turn off the flashlight, while if you buy the paid version, you can use 3- or 4-tap activation mode to deactivate it.
Somehow the developer had to find a way to earn some money, and this is a good way, since even from the free one, just by launching the app you can turn off the flashlight.
Among other features of the app is the programming automatic shutdown after a certain time, modification of the time to perform the keystrokes or even deactivate this function of the power button to use it as a normal app.
