Noxturnal App 1.3.2 - Release Information, Recommendations and Known Issues


Since the release of the Noxturnal  App 1.3.2, the Nox Medical Product- and Marketing team has received feedback about the product's performance in the field. This document is intended to help explain what is required for an improved user experience.


Noxturnal App 1.3.2 can be downloaded from the Android App Store or updated from the App Store of your supported tablet. 

Recommended Android Tablets for Noxturnal App 1.3.2

The Noxturnal App from 1.3.1 and later differs from the previous release (1.2.1). The main difference is the ability to connect to the Nox A1s via Bluetooth 5. 

This design change has put more strain on the technical capabilities of the used Android tablet. Unfortunately, some users report that the tablet is non-functional, slow, or not working as expected.

However, the issue is not software related as there are Android tablets that are technically capable of running version 1.3.1 or later and those are recommended below:

  • Samsung Galaxy Tab A7
  • Samsung Galaxy Tab A7 Lite
  • Lenovo Tab K10
  • NEC Lavie T11

We intend to expand the list of recommended tablets and therefore highly appreciate any positive user feedback, especially related to the Bluetooth connectivity between the Noxturnal App and Tablet to the Nox A1/Nox A1s. Based on positive user feedback and related internal testing, additional tablets will be included in the recommendation list with time.

Software Requirements for Noxturnal 1.3.2 

Android 6 is the minimum required software version to run Noxturnal 1.3.2, but performance could be impacted with this older version. As of June 2023, Android 13 is the most recent release. 

The Samsung Galaxy Tab A7 is currently eligible to receive this update, as well as the Samsung Galaxy Tab A7 Lite. However, it is always important to check if your device is compatible with the latest Android version released by Samsung.

On the other hand, the Lenovo Tab K10 and the NEC Lavie T11 do not have further operating system updates available. Their most recent Android version is Android 12, and their manufacturers have not announced any updates beyond that.

Troubleshooting the Noxturnal App 1.3.2

In case of an unsuccessful connection to the Noxturnal App, you should follow the troubleshooting steps below:

  1. Close any other Apps that are using Bluetooth connection
  2. Following step 1, it is often sufficient to close the Noxturnal App on the tablet by performing a forced stop of the application.
  3. If step 2 has not already resolved the issue, restart the Bluetooth connection on the tablet by turning it off and then back on again.
  4. Reboot the tablet

Location Permission

When the app is used for the first time a pop-up window is displayed that asks permission to access the device's location. For the app to function properly this permission must be granted. The app must have access to the device's location while using the app

This permission is a requirement from Google and has little to do with the Noxturnal app. This permission is necessary to ensure the user understands that his location is discoverable while Bluetooth is turned on.

If the location permission was not granted when the app was first installed, it might be necessary to re-install it and allow access to the location services while using it.



Known issues with the Noxturnal App 1.3.2

Nox SAS Solution configuration and impedance checks are currently not supported by the Noxturnal app. This has been placed on the development schedule and will be supported in the future. 

Downgrading to the previous version of the Noxturnal App (

If a user has upgraded the Noxturnal App to 1.3.1 but is not happy with the product performance of the device after the upgrade and is not using the Nox A1s, it is possible to downgrade again to the previous version 1.2.1.

The user needs to uninstall the current Noxturnal App and manually install the version which can be accessed below:
