title: Low entropy on Android
body: <p>Whenever the entropy pool goes less in android we can easily observe sluggishness in the device but i do not see a similar behavior on linux (ubuntu). I m using 2GB Ram in both. 
  Why is entropy pool having so much effect on the performance of the device?
  And how can we make sure that the entropy pool is high always?</p>
  
  <p>you can verify this by executing the following command</p>
  
  <pre><code>$adb shell cat /proc/sys/kernel/random/entropy_avail
  </code></pre>
