As we know, Google purchased Motorola Mobility and with that purchase came thousands of patents for mobile devices. A document posted online shown that there was one patent missing and Google has just applied for it. That patent was one for a multi-LED flash to be embedded on the back side of a smartphone, or tablet for that matter. The idea behind a multi-LED flash is so that a low light photo situation can have different levels of light and will create a better exposure for the photo. Phones on the market today typically have one LED flash, or maybe a dual-LED flash...
