Can't forward pictures since 8.1.2 iPhone6

Question

The button to forward or delete is covered by the ui for entering text. If I click and hold then click more it gives me the option to select multiple messages, and everything at the top looks normal. Just the bottom about a 1/2" is un clickable and looks likes the minimized keyboard. If the keyboard is open and I try to select a picture from an album it will let me go thru all the steps but once I click the picture I want the keyboard pops back up and I can't click anything. No part of the screen works. I have to go home screen then back into the message for it to work. If the keyboard is minimized I can add pictures with no problems. This all started after I updated to 8.1.2.
and while typing this the keyboard is freaking out. Putting capital letters where ever and not letting me enter more text without closing the keyboard and reopening.

Answer 1

close out of the message app, double tap home button and completely close out of it.
then do a reset, no data loss hold down the home/sleep button together until you see the apple logo and then release, then wait for the phone to boot back up.
