According to blog.shaq.com (yes, that Shaq), turning your smartphone into a blacklight device is a simple hack.  It can help with assuring cleanliness in hotels or from pet accidents, or can decode secret messages if you write using dish soap.  The hack was tried on an iPhone but also works for Android devices.

Seriously, you can freak out people with "ghostly" messages...from your dish soap.

         -Cut a small piece of tape.  Fold it over, leaving a flap so that the tape may easily be removed from your smartphone.

         -Apply the tape over your phone's back camera flash.
 
         -Apply a layer of blue Sharpie marker to the tape.

         -Apply a second layer of tape in the same manner, also Sharpie'ing it blue.

        -Apply a third layer of tape and color that one using the purple Sharpie.

Caution:  may make selfies look a little different.
