Is this app a security risk? On my originally Sprint SGN2  with screen off  to toggle LED on/off  press one Vol button  then the other. Cool! With screen on  press both simultaneously. Note that in app settings  the Screen Off timer keeps Android awake for time specified or indefinitely after screen turns off to allow volume buttons to keep working. Sleep/awake refers to CPU attentiveness  which is different than Screen on/off  and both are different than Sceenlock on/off. Is it risky leaving Android awake with screen off?
