When texting on my 5s sometimes a grey bar pops up in my outgoing text box and I can't see what I'm typing. In the bar there is something that looks like a digital clock, and it always shows 0.00. Nothing I do makes it go away except turning off and on the phone. Anyone else having this problem? It's been happening since I downloaded IOS9 but I don't know if they're related. What's happening?
