Dear Friends, I have an idea to solve the big problem in smart phones. Many smart phones is not clearly visible in afternoon time, because the sun rays disturbs the phone view, now i found a solution to rectify the problem. There is a simple logic, a sun having optical signal so we create the application like Optical signal finder and automatically increase the screen brightness. For eg: if you walking in afternoon time, you got a call from some friend, at the time your phone is not visible clearly at that moment you are irritating about smart phones., so i create the application for solve the problem. Friends, please share your thoughts.
