Google is releasing Fitbit Air firmware version 253.2, an update that concentrates solely on enhancing reliability and addressing minor bug fixes, with no new features introduced.

This marks the second firmware release for the wearable. Google advises users to install the update during the day or evening, as performing the update around midnight may temporarily disrupt the daily step count. The installation process requires the Fitbit Air to be charged to at least 50% battery, connected via Bluetooth to a phone or tablet, and have the latest Google Health app installed.

The update takes approximately 10 minutes to complete. Users initiate the process through the Google Health app. While the update aims to improve the device's performance, the changelog remains vague, detailing only "minor bug fixes" without specifying which issues are resolved, leaving users to infer the exact improvements.
