Re: Looking for app that lights up phone when receiving text mess
I use Missed Message Flasher Free. It will flash your bottom buttons (home, back, etc) and your screen periodically based on the settings your choose (i.e flash for 1/2 sec every 10 seconds) for items you choose to monitor (calls, sms, email, calendar, etc.). I used to use noLED, but it uses more battery than this because once you miss a call/sms, etc., the screen turns on and stays on until it reaches a timeout you specify during setup.
It does have access to you data, just like noLED and and third-party messaging apps, but that is required so that it knows that you missed a message/call, etc.
