The German Corona warning app is said to have not worked properly over a long period of time. The warning of dangerous encounters did not occur in the background of Apple’s iOS operating system, as assumed, but only when the app was actively open. Android also had problems due to the background update. Some devices’ sleep mode prevented updates while the app was not open.

The developers have now fixed the problem with updates. The latest version of the application must be installed so that the Corona warning app can also warn directly in background mode. The easiest way to ensure this is with automatic app updates.

With the current iOS 13, applications downloaded from the App Store are automatically updated by default. There are no notifications to update the apps.

If you are unsure whether or not you have deactivated automatic updates, you can do this on iOS devices under “Settings /” own name ”/ iTunes & App Store”. There, the slider next to “App updates” should be highlighted in green. Otherwise it has to be pushed to the right to activate it.

Update the warning app in the App Store

You can still manually update apps. If you want to check an app version or force updates, you can tap the “Today” button at the bottom of the App Store and then tap your own profile icon at the top. Then pending updates and release notes appear – such as the current version 1.1.2 (as of July 27) for the Corona warning app for the iPhone. For a manual update, tap on “Update” next to the app or on “Update all”.

Android users even have three options for updating apps: some automatically, all automatically or manually. To automatically update a single Android app – such as the Corona warning app – open the Play Store app, tap on the three-stitch menu icon and then on “My apps and games”. Then you select the desired app, tap on the three-point menu symbol and select “Automat. Update ”.

To update all Android apps automatically, you also go to the three-line menu, but then select “Settings” and tap on “Automatic app updates”. Update delays can occur here if users have only set up auto updates via WLAN, but no WLAN is available, or there is a registration error on the Google account.

Important setting for Android

Therefore, manual checking and updating of important apps can also make sense here. The route leads via the three-line menu and via “My apps and games / installed”. In the list you simply tap on the “Update” box behind the entry of the respective application. The Corona warning app for Android is currently version 1.1.1 (as of July 28).

Unlike iOS devices, Android users still have to make an important setting so that the warning app works reliably in the background. To do this, open the three-point menu in the app, select “Settings” and then “Prioritized background activity”.

If the function is set to “On”, there is nothing more to be done. If it is set to “Off”, you simply move the slider. Shortly afterwards, Android asks in a small pop-up window: “Should the app always run in the background?” This has to be confirmed with a tap on “Allow”.

Check contact investigations

In the settings of iOS and Android smartphones you can check whether the app works. On iPhones, users open “Settings”, “Privacy” and “Health”. Under the “Covid-19 contact protocol”, the “contact checks” can be called up. If you see a list of dates and times here, you can see the days on which the warning app generated and checked keys. If a day is not listed, the app has not queried any contacts on that day and therefore only works to a limited extent.

The list of contact checks can also be viewed on Android. To do this, users click on “Settings”, “Google” and “Covid-19 Notifications”. Under “Checking for possible encounters” the log of the dates and times of the past data comparisons is listed.
