In case of a failed verification (RED), the app should only display the reason for the fail

[RalicaY]

Describe the bug

Despite a failed verification, the verifier app shows the certificate data set and no reason for failure is shown.

Expected behaviour

In case of a failed verification (RED), the app should only display the reason for the fail.

Steps to reproduce the issue

1. Open verifier app;
2. Scan a QR-Code for an invalid certificate.

Technical details

Galaxy XCover 4, Modellnummer: SM-G390F,
Android-Version: 9, Verifier App 1.0.0

Possible Fix

Additional context

Additional info: This behaviour decribed above occures just only for Android-VerifierApp.
IOS-VerifierApp shows only the reason(s) of the failed check (without showing any further datas of the vaccination and the vaccinated person).

@ltranvan could you please provide specific QRs and specific expected errors to be displayed?

@ltranvan could you please provide specific QRs and specific expected errors to be displayed?

I have asked @RalicaY to give you the info needed. But in general I would expect that Android-Verifer would list the same error message (only the error message of the failed signature-check and NOT the data set!) as displayed by IOS, wouldn't it?

[RalicaY]

This Certificate is invalid. The reason is: "The test result is positive."

[RalicaY]

After scanning the above invalid QR Code with the iOS Verifier App -- the reason for invalidation is displayed: "The test result is positive."

[RalicaY]

Other specific Errors to be displayed are: "The cryptographic Signature is invalid.", "The test date is in the future", etc.
