Establish remote desktop control of ubunto 16.04 from android phone

[mahesh]

Hi all,

I am trying to get a remote desktop access to my ubuntu 16.04 from an Android 11 (OnePlus smartphone).
When trying with IOS based operating systems (iPhone 8 and iPad 2), works perfectly using RD Client, same for windows but doesn't work with any Android phone I've tried.
Trying to avoid upgrading ubuntu right now, any ideas on what's happening?
