Screen Display Difference | Entry Source, Device Prompt, and Local Record
A Ledger screen display difference should be read in order: entry source, device prompt, connection context, and local record. The device screen and the app page can show different parts of the same task, so the record should not collapse them into one conclusion.

Read the Device Screen Before the App Page
The device screen is the confirmation point for the task in front of the user. If buttons or screen prompts are unclear, compare the situation with button response and screen-state records.
Compare the Entry Source and Task
Check whether the app page, browser page, or mobile permission prompt is connected to the same task. Do not type recovery phrase words or PIN values into a page just because the screen looks different.
Check Connection Context One Item at a Time
Connection state, cable, mobile permission, and app window can change what appears on screen. The Ledger Wallet not opening record is useful when the app state itself needs a separate note.
Store a Local Screen Note
Finish with device model, visible prompt, entry source, and next check. The local note should describe the prompt and context, not sensitive recovery material.
