I cannot initiate new emails or reply to most that I receive. Also have lost many contacts from contacts folder. My iPad (16G) is about 3-4 years old and is up-to-date on the latest updates. This has been happening for 3-5 days now. Using the stylus, I cannot get the keyboard, and the send key will not work. The cancel key will work. It seems like the stylus isn't working, but it works on searching the net. I have no idea what caused this. I have checked in Settings for any possible causes but cannot find any.
