Yeah. unfortunately not as of yet. Probably sometime in 2017Google messager for awhile, but went back to stock. RCS in Google messager doesn't work with T-Mobile.
Have it set the same way here, both with iOS emojis and the wife with the iPhone 7+. I used to hate iPhone even though the 3GS was my first smartphone. Also at one point had 4 and 4s bet then went Android and thought I'd never be tempted by Apple again. Then the wife got the 7+ due to it was the only phone with, at least somewhat, of a physical home button in a big screen size after the whole note 7 BS due to loss of trust in Samsung. Needless to say, I actually started to like the 7+ but the slow as f*** charging is a deal breaker, plus the more I use my v20 the more I'm glad I didn't. Back on topic though, the emojis that come stock on the v20 are uglier than trumps a**!Textra... Mainly customization... Plus I like being able to use the iOS Emoji with the wifey (iPhone user but I still love her)
Unfortunately Sprint is the only carrier in the US using RCS right now, or at least to my knowledge, and I'm on T-Mobile. As soon as RCS is available on my carrier I'll probably swap over unless Textra or stock gets support. Though it may not matter much because 99% of the people I text have Apple crapPhones.I'm using Google messenger, RCS is fantastic.
