How to hide the music bar for my Iphone 5?

I'm not 100% sure what its called, but I'm talking about the bar on the screen when playing music, the one that shows the total time of the song and at what time point its at, and where you can choose to shuffle and/or put on repeat. I'm pretty sure there's a way to hide that when you want, can someone help me out?

Tap the screen.

  • Will a screen protecter hide the scratches on my iphone? The front screen, the glass, has alot of small scratches all over the front and a crack from the bottom corner to the other side, will a screen protected make the scratches less noticeable? I'm not worried about the crack, it's hardly noticeable.
  • Where would you hide dirty pictures on your iPhone? So that probably sounds kinda bad. But I have some guy friends who were talking about them having secret places for their dirty pictures on their iPhone's and it got me thinking, where would you hide them? I have an iPhone also, and I have some things I would like to be kept secret, so people looking through my phone wouldn't find them. Please don't go though the whole "you're too young for that kind of thing," or any other long speech.

  • Music app that works with one bar on iPhone? I like to listen to music while I'm in school and I can connect to their Wi-Fi, but I only get one bar of reception there. Sometimes I get two, but it's pretty rare. All my music apps and the music on my phone don't work there so are their any apps that can still play music with little reception?
