Not sure if you guys are asking me or the OP (haha) but here's my version. It's just dead and not doing anything. I can't clear cache or force stop, because the beta Messages isn't trying to use it. When I went into the settings using activity launcher, there's no RCS flags to turn on. Also, when I went into settings using the Google dialer and code, there was the LTE profile and emergency services but no RCS.
I don't know what's going on, unless Verizon removed that part from the update or it somehow was left out. I wouldn't put it past Verizon to do something slimy like that, freaking douchebags.
