What looks like a talk bubble with three dots in it appeared in my notification bar today, almost like some sort of instant message. When I pulled it down to open it and tapped on it it wouldn't open. Alls it said was "(email address) wants to..." I couldn't read the rest because I couldn't open it, so I dismissed it. This is the second time i've had this odd thing appear and i'm not sure where it's coming from. The first time it happened it was someone else's email address and it said "yo!", again I couldn't open it or respond. I've went through my apps and I can't figure out whats installed that would do this. Any thoughts? Thanks!
