Android :: Want To Recreate I Phone Conversation Style

I have my hand cent set an I Phone conversation style. The other day i was scrolling down reading messages and all of a sudden the bubbles went from about half the screen to stretching all the way across the screen. One on top of another. But they were still in bubble format and different colors for sent and received. They were just longer which i thought made them easier to read. I kind of liked it, but next time i opened it they were back to normal. I'm not sure if this was some kind of glitch, or if some way i was pressing down on the screen made them change. But I have not been able to recreate this.
