Cell phone looking thing in panties

There's a scene maybe 1/3 into the film with 2 girls dancing and 1 laying on the couch, all in their underwear. The brunette dancing has something in the left buttcheek of her panties, it looks like an iphone lol, I know it's obviously not but she definitely has something smartphone shaped and sized, or maybe a bit larger bouncing around in the back of her panties. ANybody else notice this?
