Abbott FreeStyle Libre 3 App Recalled Over Sensor Signal Loss: Health Canada

Health Canada has classified a recall of the FreeStyle Libre 3 App as Type II. The notice covers several versions of the Android and iOS apps made by Abbott Diabetes Care Ltd. It was published on October 26, 2026 under identification number RA-82855, with a recall date of October 16, 2026.

The recall follows a security update to the app. Abbott says the update was needed to keep the apps secure, but the fix introduced an unintended defect. Under certain conditions, the app can lose communication with the sensor for a prolonged period.

Products Affected by This Recall

The recall covers the FreeStyle Libre 3 App on both Android and iOS, model V3.4. The affected versions are listed below for each platform.

• FreeStyle Libre 3 App (Android): versions 3.6.4, 3.6.5, 3.6.6, 3.6.7 and 3.6.8
• FreeStyle Libre 3 App (iOS): versions 3.6.4, 3.6.5, 3.6.6, 3.6.7 and 3.6.8

No units, serial numbers or UPC codes are given in the notice. Identification depends on the app version installed on your phone.

What Triggered the Recall

According to Abbott, the company identified an important security update for the app. That update was meant to address a sensor impersonation vulnerability, a weakness that could let something other than the real sensor pose as one.

The mitigation itself caused a new problem. Under certain conditions, it can result in a prolonged loss of communication between the mobile application and the sensor. Health Canada lists the issues as medical devices, device compatibility and medical devices, performance.

The notice does not describe any injuries or incidents. It also does not say how many users or how many installs are affected.

Who Should Be Concerned

Anyone in Canada using the FreeStyle Libre 3 App on an Android phone or an iPhone should check which version they have installed. Users on versions 3.6.4 through 3.6.8 are the ones named in the recall.

Because the problem involves the link between the app and the sensor, it matters most to people who depend on that connection throughout the day. The notice is aimed at the general public.

What Consumers Need to Do Now

Abbott advises customers to update the app right away to the latest version, 3.6.10, which is intended to rectify the issues. Here is a simple way to act on the notice:

• Search for the FreeStyle Libre 3 App and check the installed version.
