"I used it until I tried to SMS message someone, but they are on Hangouts too, and it would not allow me to send them an SMS. I have other friends who are on Hangouts and it allowed me to select either Hangouts or SMS, but for that one person, it would not. There are other things I don't really like about it. There is virtually no customization. "
i have this problem as well, only one of my contacts too! i can choose between sms, or hangouts with every contact except this one, it drives me crazy! i never thought about looking to see if his number was listed as a home number, but i never had this problem with the default messaging app on any other phone i have ever had... so that tells me hangouts is broken... i like some things about it, but i dont like the lack of features and custimization.. the all white background with white text blocks is horrible looking... i will give it one more chance, after that off to a third party app!
