Hey guys, Not sure if this has been asked or not... But last night I was playing on my iPhone 5 in the dark and noticed a little tiny red dot dimming and lighting up again beside the ear piece on the left. It was faint and you have to look for it. Wasn't sure what this was. I assumed the auto brightness light, but I don't have auto brightness on. Now that I noticed it though, I keep seeing it when in the dark lol. Anyone got some insight on what it is? Thanks in advance.
