Everytime I take a picture with the front facing camera this small blue-ish smug shows up. It's very noticeable in low-light situations but not too much of a problem when the lighting is good. It shows up in other camera apps as well, such as Snapchat. I tried a factory reset but the problem persists. I'm assuming there's something wrong with the hardware even though it has no scratches and I have never dropped it. Any suggestions other than sending it in for repair?
