title: Can't test app on my Samsung Galaxy S+ Xamarin Deployment failed because of an internal error: Permission denied
body: <p>I have weird problem. I can't test my app on my real device (Samsung Galaxy S Plus). I am coding Android App in Xamarin.
  I was trying to change different options with using shared Mono runtime, and fast deployment, but it didn't work :(
  I get such logs during building:</p>
  
  <pre><code>// ---------- (Mono runtime unchecked) -------------
  Detecting installed packages
  
  Waiting for packaging to complete
  
  Installing application on device
  
  Deployment failed because of an internal error: Permission denied
  
  Deployment failed. Internal error.
  </code></pre>
  
  <p>and</p>
  
  <pre><code>// ---------- (Mono runtime checked) -------------
  Detecting installed packages
  
  Installing shared runtime
  
  Deployment failed because of an internal error: Permission denied
  
  Deployment failed. Internal error.
  </code></pre>
  
  <p>I have no idea how to solve it. Releasing app to .apk works normally, but it's so uncomfortable to Publish Android Application, then copy .apk to the phone, install it and test...</p>
