Flashlight Quick is an easy secured app to turn on/off the flashlight by just pressing both the volumes together. It is quick, handy, conventional.
Flashlight Quick uses Accessibility services
This Quick Flashlight app requires service to run in the background to intercept PHYSICAL VOLUME BUTTON KEY presses. Since a normal 'Service' cannot check Hardware Key presses, an 'Accessibility Service' is needed for this purpose. It does not do anything apart from checking Volume Key presses!
Moreover, the App doesn't have 'Internet Permission' hence it can't send any user data to anyone.
With help from Flashlight Quick, you just have to turn ON the flashlight by pressing the Volume UP button 2 times in a second. You can also press the volume buttons at the same time in order to turn ON LED flashLight. You can access the ultimate hardware flashlight without having to enter any app fast and easy. Moreover, with help from FlashLight Quick, you can get the brightest light from any torch or Flashlight app, and the value that you can get this way is superb!
