The Watch GT 2 does support blood oxygen saturation monitoring after all, but Huawei left its Sp02 sensor disabled for six months
While Huawei has replaced the Watch GT 2 with the GT 2e, the Chinese company is still adding software features to the popular smartwatch. The latest addition has been a long time coming too, with people having raised its absence as a concern months ago.
While LiteOS 188.8.131.52 enables the device's Sp02 sensor, Huawei claims that the update improves overall system stability, too. The update weighs in at a modest 19 MB and is available as an OTA. Your watch must be connected to your smartphone via Bluetooth before it can be updated, though.
