When I try to compose a text message, there is a timer icon "0:00" that prevents me from seeing what I'm typing.
Since downloading iOS 9.0.2, every so often when I go to compose a text message, there is a grey field in the field that is usually white (where the message is displayed as you compose it) and a timer icon. I can still compose messages, but can't see what I'm typing when this happens.
iPhone 4S, iOS 9.0.2
