Mountain View / Berlin (dpa) - Google has eliminated the error in the technical interface of the Corona warning app for Android smartphones.
The Internet company announced on Thursday.
The error had led to a number of users of the Corona warning app not having received the current result of the risk assessment since Tuesday evening.
Several users reported on Twitter and the developer platform Github that the app did not update the risk status.
However, the error did not appear on Apple's iPhone.
Google said they discovered a problem with the notification system on Android in the late evening of January 12th (local time).
«We released a bug fix.
It can take a few hours before the devices are up to date again. "
In some cases, Google will also work directly with the developers of the corona warning apps to help with the recovery.
The problem did not result in loss of data or information about potential hazards.

The error in the Google interface affected not only the federal corona warning app, but all comparable solutions worldwide that are based on the so-called Exposure Notification Framework for the Google Android operating system.
This is the technical interface that Google makes available on Android phones via its Play Services.
The interfaces from Google for Android and from Apple for the iPhone ensure that the risk determination via Bluetooth radio can function at all without the battery life being dramatically reduced.
The Corona warning app uses Bluetooth technology to measure the distance and the duration of the encounter between people who have installed the app.
The mobile devices “remember” encounters if the criteria set by the Robert Koch Institute (RKI), in particular with regard to distance and time, are met.
Other data such as the place of encounter are not recorded.
According to the Federal Ministry of Health, the Corona warning app has so far recorded over 25 million downloads and experts estimate that around 23 million people are actively using it.
