I would recommend LED flashlight! Best flashlight on shaking power button and Widget.
If you have an LED on the camera on your phone then this app is best to turn it on and transform your device into a flashlight.

Some of the best features:
- Tap the app to turn on / off the flashlight!
- Shake your device to turn on / off the LED! (without re-enable or unlock the phone screen)
- Press the Power button 3 times the device to turn on / off the LED! (without re-enable or unlock the phone screen)
(The free version contains a limited number of: turning off the flashlight by power button)
- Press Widget to turn on / off the LED! (without the inclusion of the application)
- Flashlight works even with off-screen!
- For devices that do not have the ability to light the LED screen in white
- Convenient, easy-to-use user interface and navigation
- Can be set to automatically start the application when switching on the device
- Automatic shutdown after a fixed torch setup time
- Active development application (email me if you have any questions, suggestions, comments)
- More coming soon!

Enjoy it!
