when turning phone in lanscape mode, screen freezes

[cloudtp2]

let me try and explain what happens.
when i turn the phone and pull the keyboard out to text, the phone screen turns over like normal, but when i press the send button it does nothing, i also cant scroll the screen or go into menu. i have to close the keyboard turn the phone to normal screen then press send. does that in every screen, when i go to my start page, i cant scroll down or press on a app, unless im in normal mode. wtf..
i have 6.5 stock from sprint. i have reset it many times. took most of my apps off. i dont want to do another hard reset.
ever since i flashed the phone to 6.5 iv been getting all these problems, also the text message thing when it gets stuck for minutes is really pissing me off. i have to keep deleting my messages every day.
this is so stupid.
i really like the phone when it was 6.1, now its like i want to smash it.

anyone else with the same problem. plz help me out.
