Phone Checkup - Device Test

Phone Checkup - Device Test on the inner screen: fills the whole inner screen. It gets 2,853 × 2,007 pixels, drawn to the geometry measured in the simulator.

How we know

How we decide

  1. Verified by the community

    The iPhone Duo community lists it as ready.

Not what you see? Report “Ready” as incorrect

This page says version 1.1.0 fills the whole inner screen. If that’s not what Phone Checkup - Device Test looks like on your iPhone Duo’s inner screen, tell us. It changes to “Not ready” once three people report it, at least one with a screenshot.

Optional, but it’s the proof that lets reports change the answer. Your screenshot stays on your device: we only send a tiny grayscale copy to check it.
