But i thinks that this option not serve because if some person wanted to send some whatsapp or facebook o tws, etc u never now until you turn on the screen. but maybe exist some app that turn onn automatic the red( wifi or 3g) and turn off to. Example, now is 10:00 am, the movil its turn off the screen, the wifi or 3g its turn off. 10:05 the red turn onn automatic for 2 minuts, after that 10:07 the red turn off again, after 5 minutes ( 10:12 am) the red turn on again for 2 minutes, after that ( 10:14) turn off again.
i explican good ?
