Observations
Record both screen sizes before the layout note
A foldable phone with two named screens is two layout conditions. Write both before you describe the page.

The Verge reported on September 9, 2026 that Apple announced a foldable iPhone, the iPhone Duo. The report gives a 5.4-inch outer screen, a 7.6-inch inner screen, and an IP68 rating.
This note does not review the phone. It uses those two published sizes as a reminder: a device with two screens is not one viewport.
Put each screen on its own line
Line one: outer screen, 5.4 inches, source The Verge, September 9, 2026. Line two: inner screen, 7.6 inches, same source. Line three: IP68, same source, and a note that a water-resistance rating is not a layout measurement.
If you later measure a unit, add those numbers under the published ones. Do not overwrite the cited figures.
Say which screen the sentence is about
It fits and It wraps are useless until the screen is named. A control that is comfortable on 7.6 inches can collide on 5.4 inches. Write the screen next to the observation.
Staff reactions in the same article are preferences. Keep them out of the measurement lines.
Stop when you have not seen the screen
This site has not held an iPhone Duo. The honest layout note ends at the published specification. The next sentence would require a device, a browser, and a page.
That ending is the result. A missing measurement is a recorded state, not a failed review.
