My iPhone wont allow me to rotate the screen?

How do I turn it off so the lock next to the battery percentage is not there?

Double tap the home button to open the switcher and slide it to the left to the music controls. To the left Is the orientation lock. Press it once and your all set.

You can double press the home button and slide to the part that has the play button, next to it you'lll find an arrow shaped as a a circle. And if it has a lock in the middle then press it. If it doesnt it must be something else
