Could you please explain what are the copyrights for Ubique Innovation and why? I thought the code was developed with public funds

The first version of the next-step has shown the number of contacts on the main screen. I used this to show that the app is doing something and to check how many contacts I "created". I would recommend to include this also in the final version of the app. I know that this does not represent the "real" number of contacts, but I think any indication, that something "real" is happening would be very useful.

I can't connect my Polar sports watch to the Polar Flow application when the Covid app is running. The Polar device uses Bluetooth for sending data to the phone. If I turn off proximity tracing than all works fine.
I experience this on a Samsung Galaxy S9.

currently pinning (class CertificatePinning) is only used within class ConfigRepository ( all https requests should be protected )

I use commit 84626fd. The notification in French when the Bluetooth and the location are deactivated is not straightforward, because of the repetition of some information and after "à aucun moment" you have ".,".

Please allow for language change in App
I have my Android OS set to English but I'd prefer to see the content of the App in German.

I'm using a dev build built from f6b4efb on a Huawei PRA-LX1, Android 8.0.

When it says "restart necessary (NSBAE)", I can almost always make it go back to working by bringing up the notifications panel and clicking the notification.

I do not have adb access to this phone, so I can't do better debugging than that.

The readme says "The app will not be functional unless your Google account is whitelisted for ExposureNotification testing" but does not explain how to actually do this. Can you please provide (or link to) documentation to help end-users figure out how to do so?

As it seems there is currently no possibility to see received or distributed IDs to nearby contacts. This would allow the user to assess their exposure level.

I tried the commit 3dd348c and because by Honor 8X didn't receive the update from Google, I don't have the exposure notification api. When I try to activate the tracing an alert pop up with I think the original error message "17: API: Nearby.Exposure_NOTIFICATION_API is not available on this device. Connection failed with: ...". Maybe it can be good to modify this error message for the user.

I installed the app on a Samsung SM-T700 tablet, running Android 7.1. (api 25).

The app seems to run without any problems. But the device mentioned is not capable to transmit ble tokens due to missing hard- or firmware. This can easily be verified using an app like 'nRF connect' (on a second device).

Please add a message to clear that situation to the user. There are many moslty older devices out in the field that may have the same problem.

Issue:

App version 1.0.5 running on android 10. Whenever Bluetooth is intentionally turned off, when being at home for example, the app sends regular notifications (about 7 per day according to the android app info settings) that Bluetooth needs to be turned on in order for tracing to work. At the moment one can mute notifications from the android settings but I assume this would also mute exposure notifications. It seems to me that these notifications are a little bit too frequent and can be distracting at times.

Proposed Solution:

Adding an option to disable such notifications from the app or reducing the frequency to 1 notification per day for example.

Right now there is a lot of confusion whether enabling bluetooth and most importantly location is technically required for contact tracing to work.

See this thread for example, with lots of replies and a lot of confusing and contradicting information: https://twitter.com/adfichter/status/1265552302091403266

From what I understand, the DP-3T Android app uses Google's Exposure Notifications API to detect exposure and does not in any ways interact with the BLE stack.

In the Exposure Notifications API FAQ, it is written:

This is reflected in the AndroidManifest:

https://github.com/DP-3T/dp3t-app-android-ch/blob/d87796564efd2cb8fc73e3cb6efb8b75233562a7/app/src/main/AndroidManifest.xml#L14-L15

So the permissions in DP-3T are clear, and no location access will be required. However, the question remains whether the location needs to be enabled at all for SwissCovid to work. The Android developer documentation mentions:

So from what I understand, location access is only required to initiate a BLE scan, because that is precisely the way how the location of a user is being estimated. Just having the BLUETOOTH permission does not allow you to determine the location of a user.

So in essence, this boils down to two questions:

1. Do current Google Exposure Notification APIs require that location services are enabled on the device? (I cannot test this since self-compiled versions of the app do not get access to this API, correct?)
2. If this is currently required, is there a technical reason why access to the Exposure Notification API (which happens by whitelisting, if I understand this correctly) does not imply a permission to scan for BLE advertisement frames? (After all, even if the Google Exposure Notification stack does perform scans, the app has no access to them and thus cannot determine the user's location.)

Not needing to enable location services would be a big improvement with regards to user trust.

I am living near the border to Germany.
Would it be possible to implement a part of the backend of another country to get the validated tested ID's? If this is possible, it would be great for people near the border if you could check the box for neighboring countries to see the corresponding dangers.
You would then only need an app, because I would then have myself tested by my doctor/hospital in Switzerland. If the other countries would offer the same option (to check the databases of the other countries), these people would also be warned in case of a case from me.

This would be a nice-to-have feature.
As the app stores any contact locally, a feature which would show the number of contacts per day might be useful. The user could improve his/her behavior in terms of social distancing. It could also be a good indicator that it might be a good idea to wear a face mask.
Of course this would also apply to https://github.com/DP-3T/dp3t-app-ios-ch

It should be possible to use a main switch on the main screen, e.g. on top right of the title bar.

This main switch causes three events:

1. on/off of Bluetooth
2. on/off notifications for this app
3. activation/deactivation of the tracing.

The existing "Tracing ON/OFF" switch can thus be omitted.

Reasons:
The app is only used in public area and is only useful there.
Due to the app's continuous notifications, you will feel annoyed very quickly at home.
In addition, the power consumption of Bluetooth, despite BLE, is enormous. (SAMSUNG Galaxy Note S10+)

My experience is that the normal average user does not take the trouble or is overwhelmed,
to tap through the settings each time to turn Bluetooth and the notifications off and on again.

Another security aspect that alone justifies a main switch as described above,
In a public space with Bluetooth activated, it is easy for programmers (hackers) to get around with the appropriate software, manipulate other devices, steal personal data or damage the device.

With my expertise, I never move in public areas with Bluetooth activated.
I only switch it on briefly when I need it and then I make sure that nobody is closer than 10 meters from me.

This means that a main switch in SwissCovid would allow the user to deactivate his tracing app in a bus or train after 15 minutes, after he has assessed his position through the app, and if necessary, switch on again at any time...with one click.

Hi,
I installed the SwissCovid app, but it looks as if it goes dormant as soon as I use other apps.
So today for the whole day it says 0s in use.
Did you already encounter that?

First off great work 👍

I was able to download the App from the Play Store yesterday, not sure if this was intended or not.

I like the UI and UX, it is very simple. But what I think would help with transparency is to see the number of datasets stored on my local device. This can also be a little hidden on the info page. For example display the number of current encounters.

This is just an idea and should be simple to be implemented, but it would for sure help me to trust the app more because I can see what it is doing.

Could be, that this error is caused by LineageOS. If yes, this is more a confirmation, that the app error handling is working.
I got an unexpected error "NSBSE" (BLE_SCANNER_ERROR) with a DEV Debug build of 1.0, 0.2.6 on a OnePlus 5T with LineageOS 16.0 from 21. April 2020.

With logcat I just find:
05-13 17:05:37.610 12916 12932 I WM-WorkerWrapper: Worker result SUCCESS for Work [ id=0a138d07-2cf1-4d07-a121-bb2f0704a9f2, tags={ ch.ubique.android.starsdk.SyncWorker } ]

Since the app uses BLE, the authorization for the location must be given. According to reviews in the PlayStore, many people uninstall the app because they think that the app needs a lot of energy - because the location and therefore (in the mistaken belief) GPS is enabled.

The first time the app is launched, it should probably display some information about why the location is needed and that it is not the same as GPS. It should also be mentioned that BLE is not equal to Bluetooth (Classic), because many people think: "Other Bluetooth functions don't need location sharing, why do they need it?

On my Huawei Mate 10 Pro (BLA-L29; Android 10) the apps seems to execute exposure checks very irregularly. It happens only 3 times (July 2nd, 4th and 16th). The check at the 16th July was forced by opening the Covid notification settings in the Android system settings .

On my Xiaomi it looks like the backround mode is disabled frequently. Sometimes it shows me a red error when I open the app, that I need to allow background activity. Not sure it works always as expected, because I need to check that manually. No idea why it comes back, seems to be random, but really frequently (once a day)

Google PlayServices generate a weekly notification with a summary about the exposure tracking during the last week. In most cases this will show "Your smartphone did not find any contact with infected people.". Because this message is not coming from SwissCovid it can be confusing for the users.

We reported this unexpected behaviour to Google. The notification has no impact on the functionality of the app.

The app help mentions that the keys are stored on the device for 21 days (begegnung_detail_faq2_text). The help in the Google COVID-19 exposure notifications however says "14 days".

Phone: oppo Reno (color os)
Issue: app says to let app run in background, and tell it back 15 min after
Root cause: app has been configured to smart background running
Is it an os limitation? May be pushing a message such as "if that message occurs more than once, you'll have to change it manually in setup > search battery > power saver options" (oppo path...) Would be enough

I run LineageOS without Google Services. The application reports, that it needs updated Google Play Sevices to run, which I will not install, since they are closed source and proprietary software.

Hi DP-3T,

after switching to Android 11 beta 1, the app now constantly sends this Android notification:
"App currently unable to function properly.
It has not been possible to synchronise reports for some time. Please check that your device is connected to the internet. (ASST502)"

Internet works fine, issue occurs no matter if 4G or Wi-Fi is used.
Uninstalling & reinstalling the app or restarting the device does not help.

App version: version 1.0.3-pilot, 0.5.6
Android version: Android 11 beta 1, build RPB1.200504.018
HW: Pixel 3

I installed the application and get an error (and notification) that the "App [is] currently unable to function properly".

Model: Pixel 3 XL
OS: Android 10
Patch level: June 5,2020

Hello,

I compiled and installed the app on my phone running a pure Android Open Source Project (AOSP) OS. Unfortunately after launching the app it turns out that it has a Google Play Services dependency which is a closed source software and not available in AOSP or Lineage OS.
Is there any solution/workaround for open source android users?

Thanks!

Some steps:

1. go to the google play store by clicking the notification of updating google play services
2. do not update google play services and go back to SwissCovid
3. a message shows and indicate some error happens

With SwissCovid/swisscovid-app-ios#196 a dark mode was integrated in the iOS app. Would be nice if this could also be added for the Android version.

It should be "Envoyer", not "Enviar".

https://github.com/DP-3T/dp3t-app-android-ch/blob/c626a84fa50bcfed531ee301cd7c5e184869b055/app/src/main/res/values-fr/strings.xml#L23

DP-3T is a free-standing effort started at EPFL and ETHZ that produced this protocol and that is implementing it in an open-sourced app and server.

What Server? The App works decentralized.
Uhm, right?

F-Droid (https://f-droid.org) is the main opensource apps repository for users that do not have Google tools installed on their android.

The project could provide the APK on F-Droid to allow non google-tools users to install the app also.

The instructions for adding an app are located at https://gitlab.com/fdroid/fdroiddata/blob/master/CONTRIBUTING.md

This is dependent on issue #59

I downloaded the apk from here:

https://www.apkmirror.com/apk/federal-office-of-public-health-foph/swisscovid/swisscovid-1-0-5-release/swisscovid-1-0-5-android-apk-download/

The screenshot below is from Google Play installed version:

Pilot phase testing is hindered by restriction of Google Play country. Many researchers at EPFL/ETHZ use non-swiss accounts. Countries can be only changed once a year. Also, access to existing Google Play balance is removed by chaging the country. Therefore, a significant number of potential testers will not change their country settings. To include these persons into the pilot phase testing, the country restriction should be removed.

Currently, all you see is tat the app tells you that it is "aktiv". It would be nice to have some information about:

• Last sync from central server
• How many foreign tokens the device has seen or local has been saved for yesterday/the last 7 days/14 days

That would help get a sense of how many contacts you have.

A never do is:

• Display this data immediately updated. Reason: You might find out if a person next to you is using the app or not.

The model DPIA commissioned by the DP-3T consortium says quite explicitly that the beacon data transferred by one user to another should be treated as sensitive personal data (p 17).

One the other hand, the interface communicates in a few places that different processing operations are "anonymous". See for instance here.

Anonymous data has a specific meaning in EU data protection law, i.e. data that is not re-identifiable, and therefore not considered personal data.

Again, the model DPIA states that it is generally understood that what constitutes personal data is the same in Swiss and European law.

We see that there is thus a clash, between how the app presents what it does, and what it actually does from a legal standpoint, as interpreted by the lawyers hired by the DP-3T collaboration.

Additionally, this might be problematic in the future, if indeed the goal is to guarantee interoperability. A user operating the Swiss app in Italy would be misled by the current interface. One might argue that it would be ok, as the app could be updated, but I don't see how this would be done given EphIDs are stored for a while. Additionally this might lead to problems in case of multiple apps being installed on the same device.

The remedial is actually fairly simple: substitute "pseudonymously" for any current occurrence of "anonymously", since this would be more reflective of what is done, and the actual risk of re-identification (which underpinned the legal advice in the first place).

On some Android devices all entries on Settings > Google > COVID-19 Notifications > Exposure checks show "Number of keys: 0" and "Number of matches: 0".

This is not a bug of the SwissCovid app but of the ExposureNotification framework provided by Google. The bug was reported to Google and will be fixed with a future version of the framework. The behaviour of the app is not affected, the bug only affects the number show in the "Exposure checks" menu, the checks are performed normally with all provided keys.

English language and consistency errors in GUI.
Observed in v1.0.7 and also in earlier versons.

In English, SwissCovid shows the following at the bottom of the first page on the GUI

"What to do if...
Symptoms of the disease"
(Note that this is not a correct sentence. It is incomplete.)

"What to do if...
you test positive"
(Note that this is a correct and complete sentence)

Following each link reveals
CORRECT:
"What to do if...you test positive" takes you to a page with the same title "What to do if ... you test positive?"
The text "What to do if you test positive?" is a proper question and takes you to a page of the same name. Consistent and correct

INCORRECT:
"What to do if...Symptoms of the disease" takes you to a page with the title "What to do if ... I feel ill?"
The text "What to do if...Symptoms of the disease" is not a proper sentence.
It takes you to a page with a different title ("What to do if ... I feel ill?").
The link name and the following page title are not consistent.
Additionally, it is written in first person (I), whereas the other link/page "What to do if...you test positive" is written in second person (you).

POTENTIAL FIXES
Examples to create consistency and fix the English are:

Example 1:
The first page text could be changed to:
"What to do if...
I feel ill?"
Then the link name and following page are consistent, and in first person

Example 2:
Both the link and following page could be changed to
"What to do if...
I have symptoms of the disease?"
Then the link name and following page are consistent, and in first person.

Example 3:
Both the link and following page could be changed from first person to second person perspective:
"What to do if...
You have symptoms of the disease?"
Then the link name and following page are consistent, and in second person, thus consistent with the "person.

The error header is "no current data". I had mobile data disabled yesterday, so I assume the error is due to not having data connectivity. That should be an expected error with a user-friendly warning that the app requires a data connection (or even better: cache announcements for some time and only display a warning about missing data connection if no connection could be established in say the last 12h or something). In addition the error doesn't disappear once connection is regained, I need to manually stop the app and restart it for the error to disappear.

Edit: Turns out it was something completely different: I had the same error again while having data. At the same time I got a system notification about running out of space on the internal partition. Still would be nice if there was a less cryptid/more user friendly error about this.

I cannot activate tracing on a Google Pixel 3 XL phone. I saw simliar issues #51, but mine is reported with a totally different StatusCode.

Detailed info:

Hello there.
I wanted to install the SwissCovid app on my Honor 6x (Android 8.0.0, EMUI 8.0.0) but I got this Error:
17: API: Nearby.EXPOSURE_NOTIFICATION_API is not available on this device. and below:
Connection failed with: ConnectionResult{statusCode=UNKOWN_ERROR_CODE(39501), resolution=null, message=null}
The Google PlayStore is Version 20.5.19-all [0] [PR] 316024227
Bluetooth is activated and I tried to reinstall the application.
Anybody knows what's happening?

Hi DP-3T team!

Nice work for a first draft version!
I found the following issue on my phone: the left and right sides of the input field in the fragment_inform screen are slightly cut (the left border is missing on the first digit and the right border is missing on the last digit). See attached screenshots.

Device: Motorola Moto G9
Android Version 9
Display size: 1080x2160

Why?
ios 13.5.1 iphone 6s. bluetooth on. SwissCovid app installed.

ios menu > privacy > bluetooth (/ health) COVID-19 Exposure logging > Off. Not available in your region. ......

note: apple id & handset region is set to switzerland. handy nummer ch.

I was wondering if there is any way to simulate a warning and an infection in the test version of the app?

FYI.

Yes, it is downloaded over HTTPS from dl.google.com, but I don't think is good enough.

I have installed the SwissCovid app 1,5 week ago on my Android phone (Samsung A40, Android version 10). However, I am constantly getting an error message "An unexpected error has occurred while synchronising reports (AGAEN39508)" (see screenshot). I already tried uninstalling-reinstalling the app, but the error persisted.
