So pretty much everyone has a smartphone, and a few hundred million people have the Facebook app. And everyone knows when you turn the phone sideways, the app and screen adjust to show a wider view.

Except mine. My gyro is fine, every other app does this. Temple run works fine, tilting my phone causes my character to tilt sharply, no problems there.

My fiancé has the same phone as me, iPhone 4S. She has the same updates as me, and uses the same facebook app. When she turns her phone sideways, it works normally and does what it's supposed to - it turns sideways. But when I do it, nothing happens. It just remains vertical.

Wwwwwhhhhhhyyyyyy.
