While texting my screen randomly resizes to about 2/3's of the screen and I have to hit the full screen button in order to get it back to normal. is there a way to disabled whatever is causing this? Attached is a Picture of what it looks like.

Looks like you're putting it into One Handed Mode. Go into your settings and turn that feature off.
