title: What is the sampling frequency of the accelerometers embedded in Android smartphone?
body: <p>I'm looking to know the <strong>sample frequency of smartphone</strong>, and - more important - if this parameter is equal for the most types of Android smartphone.</p>
  
  <p>I know that  there are two mode of sampling: low at 20 Hz and standard at 100 Hz. But yesterday I've done some experiment with several type of smartphone and the "Samsung Galaxy Note 3" seems has a sample frequency of 200 Hz.</p>
  
  <p>Now, my question is: is it true?
  And, if yes, do you know where I could find one, or more, academic papers, or technical data sheets, about this issues?</p>
  
  <p>Thank you in advance,<br>
