Are stored measurement data deleted when a SONAPHONE app is uninstalled and subsequently reinstalled?

No. When a SONAPHONE app is uninstalled, the measurement data recorded with that app are not deleted.

After reinstalling the app, the previously stored measurement data are available again.

Which data are reset when an app is uninstalled?

Only app-specific basic settings are reset during uninstallation.

These may include individual settings configured within the respective app.

Previously recorded measurement data remain stored in the device memory.

How is an app uninstalled?

SONAPHONE apps are managed using the Software Manager.

To uninstall an app:

1. Open the Overview from the home screen.
2. Start Software Manager.
3. Select Uninstall for the respective app.

The app is then uninstalled from the system without deleting the existing measurement data.

How is the app installed again?

The corresponding installation file is used to reinstall the app.

If required, the file is first transferred via USB to the following directory on the SONAPHONE:

Internal memory > Sonaphone

The app can then be installed using Software Manager.

For apps requiring a license, the corresponding license file may also be required.

Should measurement data still be backed up?

Yes. Although measurement data are retained during a normal app uninstallation, important measurement data should generally be backed up regularly to an external storage medium.

A backup is particularly recommended:

• before software updates,
• before major changes to the device,
• before troubleshooting,
• before sending the device in for service.

This ensures that important measurement and inspection data remain available independently of the condition of the device.
