How do I take a 0.5 selfie on iPhone?

Short answer0.5x is the rear Ultra Wide camera, so a true 0.5 selfie means using the back camera at 0.5x with a timer or remote. For a wider front-camera selfie, tap the two-arrow button on the front camera (iPhone 11 and later) or use an iPhone 17 model, which has a wider square front sensor.
