title: What does x,y,z values obtained from accelerometer in Android indicate?
body: <p>At first I thought:</p>
  
  <ul>
  <li>x - tilting the phone from left - right and vice versa</li>
  <li>y - upside down and vice versa</li>
  <li>z - lifting the phone up and down</li>
  </ul>
  
  <p>But it doesn't seem like that. Can anyone correct me if I am wrong.</p>
  
  <p>I want to know these values in-order to know the angle of the phone. Is it possible to know it using these values?</p>
