Edit: why the downvotes? It's a feature finely supported on desktop clients, and it does not work on Android - so in order to use Android Skype, I'd have to create a "pure" Skype account (with its own password!), and re-import all my contacts.
For me, that's a bug that has seen no activity for over 3 years.
I compared by running the client on OS X, Win10 and Android in the same time. OS X and Win10 clients seemed to pretty much agree on availability status and to be correct.
But on Android, contacts that are yellow (away) show often as green (available).
Worse, sometimes those who are present show as being offline.
Yeah, pretty random!
Nowadays while it's still occasionally disconnecting at random at least the indicator seems to be more honest about what's going on I would like to believe it locks up less frequently.
