I am sorry for maybe the vagueness of this problem but I am having a hard time finding anything about it and/or explaining it correctly. My Lumia 822 is almost 1 year old, I have the newest OS but these problems started happening several weeks after the upgrade (so I don't thinkt he upgrade is the problem). Anyway, I cannot send email (I can check, read, hit the reply button but cannot hit the send button...it does not respond). I also can look at facebook, like statuses, use all other buttons near the bottom but cannot post a reply to Facebook. Lastly, I cannot send text messages anymore. The button just does not respond to my touch...as the others are doing as well. It's not the screen because the buttons will work on the bottom of the screen unless I am trying to do those three things I just said. Well, when sending email I cannot hit the attach button either, they just do not respond. I have done everything I know to do besides factory reset...which is last resort.
