Glitchy! With all of the most recent updates, there is a lag time with opening messages and the keyboard appearing. Also, it's nearly impossible to "share" or "forward" a message. It doesn't actually attach the content to be sent to another conversation. So very frustrating. I've done a "force stop" and cleared the cache MULTIPLE times. I've always preferred this texting app over Verizon's, but I'm about ready to switch.
