A new film opened yesterday in select theaters, and it realistically captures today's screenagers as they navigate life addicted to their smartphones and social media apps. The film, "Eighth Grade," focuses on 13-year old Kayla (played by Elsie Fisher) who is constantly using her iPhone to access Snapchat (including the AR-powered Lens feature), Instagram and other apps. And she's far from being alone. All of her friends in school also sport iPhone models and view social media apps.
