If your android mobile doesn't have a LED light, but you want to use your mobile as a torch/flashlight then this is what you want. This app, when launched, sets the screen brightness to the maximum and disables the key-lock or your mobile going to sleep. Simple and tiny app that will always come in handy.
Note: All apps published by me are free and always will be. The permissions required for the apps are merely for the integrated ads that support me build such apps. I guarantee you that none will harm your device, so please feel free to install and try them out. Thanks.
