title: Android App is logged in even app is re-installed
body: <p>I have an Android app where I have at the start of the app.</p>
  
  <p>There is one weird thing happening with my app.</p>
  
  <p>Even I delete app and re-install, the app takes last logged in data and show me that I am already logged in.</p>
  
  <p>Below are the steps.</p>
  
  <ol>
  <li>Login to app as testuser</li>
  <li>Delete app</li>
  <li>Install app again</li>
  <li>Actually it should ask me for login, however it shows that I am already logged in with testuser.</li>
  </ol>
  
  <p>OS that I have on Android is 7.0 on S6 Edge phone.</p>
  
  <p><strong>Note</strong> : I check on S4 and all is fine. It ask me to login on each re-install.</p>
