Hello Mohd,
Thank you for your message.
Unfortunately, as of this writing, mobile Viewer for iOS/Android only supports the Full Control connection mode and does not support other connection modes available in the desktop Viewer for WIndows.
However, we already have plans to significantly improve mobile Viewer in our future updates - namely, to implement the full-fledged address book, other connection modes and more features. Unfortunately, we cannot provide any specific ETA on this yet. Sorry for the inconvenience.
Please let us know if you have more questions.
