Huawei introduced the Watch GT 2e last month, a sportier and lower-cost version of the Watch GT 2. The GT 2e comes with the blood oxygen saturation (SpO2) monitor feature, along with other fitness tracking and smartwatch-focused features. While both the devices are technically similar in terms of hardware capabilities, the SpO2 measurement feature was seemingly absent on the GT 2.
That changes now, as a new firmware update for the late-2019 smartwatch enables the SpO2 measurement feature. Version 126.96.36.199 is rolling out to the GT 2 through the Health app that brings this feature, along with the usual stability improvements. The update for the device is around 19MB in size, and can be installed on the smartwatch by heading to Devices > Huawei Watch GT 2 > Firmware update on the Health app.
Additionally, it must be noted that the progress bar on the app notifies users of the transfer progress of the update package to the device. The installation happens on the watch separately. The device must be connected to the smartphone via Bluetooth and the battery level must be at least 20%.
The SpO2 measurement feature is a welcome addition, which also brings parity between the two smartwatches from Huawei. SpO2 levels between than 94% to 100% are considered normal. Low SpO2 readings are considered to be clinical symptoms for COVID-19 as well.
In addition to the Watch GT 2, the GT 2e is also receiving an April 2020 firmware update, but it only contains bug fixes.
