FAQ: "What do the exposure check logs show?" no longer matches Android UI

Where to find the issue

What do the exposure check logs show? https://www.coronawarn.app/en/faq/#keys_matches

Was bedeutet die Überprüfung auf mögliche Begegnungen? https://www.coronawarn.app/de/faq/#keys_matches

Describe the issue

Google changed the UI with v1.8 of the Exposure Notifications System. See Exposure Notification release notes - v1.8, January 2021.

In Android there is no count “Exposure checks” any more.

The Hash value changes for every risk evaluation.

There are other inaccuracies in the English version noted in the next section.

Suggested change

For Android:

The following section needs to be removed:

Exposure checks

This value does not reflect the number of encounters. 
Please tap one level further: This is where the checks of up to 15 days are logged (today plus the last 14 days). 
Selecting an entry leads to a detailed view with the corresponding time stamps and the number of matched keys.

The second sentence below does not make sense. It needs to be re-translated from the correct German.

Timestamp

Date and time at which the check happened. 
This is independent of the timestamp of potential exposures since every key stored in the downloaded files, a separate validity timestamp is stored.

The Android label is “App” not “Data Source” (English and German)

Data Source

Identifies the app that initiated the check. 
If you, for example, also installed Immuni or SwissCovid, their app identifiers could be noted there instead of 'Corona-Warn'

The Hash value changes every time. The second sentence should be deleted.

Hash

Checksum of the file containing the downloaded diagnosis keys. 
As long as the file content (diagnosis keys) does not change, this checksum will not change throughout the relevant time frame of 2 weeks.

PR #1728 is merged. Thanks to @Ein-Tim for reviewing for iOS!

@Ein-Tim I’ve now submitted PR #1728. You’re welcome to check if it is consistent with what you see on iOS.

I tried to make the minimum of changes to make it correct. If we wanted to put in more information, we would probably need to split it into two different articles for iOS and Android.

Especially at this stage in the pandemic and the maturity of the app, there is very little discussion on these numbers any more, so I don’t think that any major extra effort would be worthwhile.
