If you do not use the WRITE_EXTERNAL_STORAGE permission in your app specifically, a few known issues will arise:
- The multi-login profile persistence across uninstalls will not work.
- On devices below API 23, attachments sent by Agents to the user will be downloaded by the OS’s download manager instead of SDK’s download manager (SDK will just show the download button, it will not show download progress and will not show the launch button when download is complete).
- FAQ Image caching will not work on devices below API 19.
Please see our developer documentation on app permissions in Android for further explanation as to why certain permissions are required.
