Corona app: "ENErrorDomain error" on iPhones

Within a few days, the Corona warning app was installed millions of times on cell phones in Germany. All in all, the app makes a very stable impression, only a few users complain of problems with use. After a few days, the error message "ENError-Domain-Fehler" with the digits 5, 11 or 13 appears on some smartphones.

Only iPhones are affected by this error message. The problem occurs immediately after opening the app when trying to update the app data. Most of the time, the app ran flawlessly for several days before the "ENErrorDomain" error occurred.

The error messages "EnErrorDomain-Fehler 5/11/13" appear mainly on iPhones with iOS 13.5.1.

The functionality of the app should not be affected by the error message. Even if the update is not displayed correctly, the contacts should continue to be recorded. There is currently no solution to the problem. In some cases restarting the iPhone will help. For some users, the app continues to run flawlessly on the day after the message appeared. Both the developers of the Corona warning app and Apple are already informed about the bug. An update is currently being prepared and should be released soon with iOS 13.6. to be published.

What about Huawei phones?

In the current version, the app accesses the Google Play services. However, the new Huawei phones work without Google services. It is currently not possible to install the Corona warning app with the Huawei P40 or Huawei Mate 30. Huawei is already working on its own solution to provide its own interface with the update of the HMS Core Contact Shield. It is currently unknown when the update will be released.

Access to location services?

In order to determine a possible encounter with a COVID-19 infected person, the app accesses the Bluetooth signal of your mobile phone. Bluetooth must therefore be activated in the settings. GPS is not used, but you should have activated location services on Android. The approval is required for technical reasons for the Bluetooth positioning. As can be seen from the source code, the location itself is not queried. Location sharing and Bluetooth run separately on iOS, so additional access is not required.

How is the battery consumption?

The setup is very simple. After downloading and installing, read the detailed data protection declaration. If this is accepted, you activate the actual function of the app. The app exchanges encrypted numerical codes with other devices in the vicinity via Bluetooth.

A concern that is often mentioned is a possible increased battery consumption when using the app. The application uses the battery-saving "Bluetooth Low Energy" system. The developers promise to keep an eye on battery consumption and may want to revise the application in the coming weeks in order to run on the cell phone with as little energy as possible. If the app is running in the background, consumption should be negligible. The coming days will provide better information about the actual battery consumption. We'll show you how to save electricity with your mobile phone.
