They should just concentrate on making it work properly on android

The amount of times it thinks I'm in a call and I'm not is far too many. Or it doesn't dial. Or doesn't ring. And if turn the video on there's a good chance it'll crash so hard I'll have to force stop it.

Which is a shame as I really like hangouts

Also the sms part should be better integrated, why can't I view/send sms on my phone from gmail?
