If you're receiving an error message that says "Application not installed" on Android, you will need to uninstall the Blink app and re-download it from the Google Play Store.  To do this, open the Google Play store on your phone.  From there, search for Blink.  Tap the Uninstall button, then tap OK.  After that, you'll be able to tap the Install button.  Once you do that, you should be able to open the Blink app normally.
