Installing on your phone

  1. Tap the download button above from your Android phone's browser.
  2. When prompted, enter the beta access credentials.
  3. Once downloaded, open the file from your notifications or Downloads folder.
  4. Android will likely ask to allow installs from this browser / file manager — this is expected for a beta build distributed outside the Play Store. Allow it, then continue the install.
