New hangout indicator meanings I have started using hangouts now that it has merged in with all my sms messages and it's cool.

However i was wondering if someone could explain the indicators that show up at the bottom left of the screen to me?

I currently know:


TinyPortrait(transparent) = current point user has read to
Dots (...) = user is typing


Unknown


TinyPortriat(Solid) = i thought this might mean they are up to date,
but considered it could be that they are watching the screen?
Small Phone Icon = No idea what this means.


Are there any others?
TinyPortriat(Solid): The user is reading the conversation.

Small Phone Icon: This indicates that the user is using the hangouts app on a mobile device.

TinyPotrait (Faded): The user read your messages above the icon.
