Support Unfortunately, camera has stopped + Unknown symbol

view story

http://androidforums.com – Hi, I really need help. Tried reset factory settings but it didn't work. Everytime I open my camera it gives me "Unfortunately, camera has stopped" now when I open any app which includes camera like InstGram, when I click on the camera icon to upload a photo. InstaGram also crashes. I'm also seeing a cellphone-like symbol/icon with an arrow on the upper right part of my camera screen. I pointed it with a red arrow on the screenshot I've provided so you'll know what I mean. Does anybody know what this is?I really really need your help. Thank you in advance (General)
