While Android devices have generally gotten better in terms of software updates, there are still some situations where a handset might receive a limited amount of major Android system patches. This looks to be the case for Microsoft’s debut foldable device, the original Surface Duo.
With that being said, Microsoft recently announced on its official support page that it has ended software support for the Surface Duo, which received its last security patch on September 10, 2023. According to Microsoft’s announcement:
Surface Android devices will receive Android version and security updates for at least 3 years from its release date (September 10, 2020). In cases where the support duration is longer than 3 years, an updated end of servicing date will be published 18 months before expiration of the last planned servicing date.
Meanwhile, the Surface Duo 2 will continue to receive security updates until October 21, 2024. This is understandable as the device is of course newer, and featured Android 11 at the time of its release. The Duo 2 made its debut back in 2021, and received the Android 12L update a year ago.
