Last week experienced something weird. I sent a buddy of mine(Who has an iPhone) a text, and apparently he never got it. I didn't get any failure notification or anything, and it's never happened before with him. Apparently yesterday, the same thing happened to a friend of mine(Who has a S3) when I sent her a text. I updated to 4.4.2 a couple weeks ago and thought that might have something to do with it, but do you think it's just a fluke since it's only happened twice? Or is this some known issue I should get checked out.
