Texting problems.

The texting screen on my 4s keeps disappearing for many hours every day.

Have you tried a hard reset?

Hold the sleep/wake button and the home button at the same time. After 10 seconds or so, the screen will go blank and the silver apple logo will pop up. You can release the buttons once the silver apple logo pops up.
