How to turn off the floating app on my iPhone 5?

Yesterday, something appeared on my phone that looks like a small, faint moon that I can drag around to anywhere on the screen. When I tap it, it brings up quick menus that I can use to pick various functions. It's kinda cool but I need it to go away. Unfortunately, I don't see how to get rid of it. It stays in whatever spot I move it to regardless of what is on the screen (e.g.address book, phone, Netflix, You Tube, home page, etc.). What is it and how did it get there?

What iOS runner game is this?

Okay so I really miss this running game I used to have on my iphone but for the life of me I can't find it. It used a stick figure and was an endless horizontal runner that consisted of levels you had to pass where you either had to get so far, or collect so many of the same coloured stars. It had special things you could collect like wings which shot you 1000 points forward or it had spring feet which made you jump really high. You could also use collected coins to pay for stuff like tiger feet accesories or devil horns etc.

Two songs will not transfer from my computer onto itunes like all the others did?

Okay, so I checked google and it was no help.
I recently upgraded from my optimus smartphone, to an Iphone 4. Now I was able to get all my music onto my computer from the old SD card, and then I was able to transfer the songs onto itunes, then onto my phone. Then i found out that two songs, two i love the most mind you, will not transfer, I drag them over like i did with the others but they won't appear in itunes, why?

IPhone 4 taking back camera pictures in black and white?

The back camera on my iPhone is taking pictures in black and white. When I click into my camera and get ready to take a picture, I can see it in color for a fraction of a second and then it quickly fades to black and white. I have an editing app that allows you to take pictures inside the camera and it does the same there. It's very frustrating. I don't believe my iPhone is jailbroken. It's a replacement iPhone that was restored to factory condition by my insurance company. Everything works besides this. What is going on?
