The updates will come to Android 6.0 Marshmallow phones and above
Google has confirmed that it will use the Google Play Services infrastructure to update Android phones with the upcoming COVID-19 contact tracing system it is building in collaboration with Apple. It should ensure that more Android phones will actually get the updates, and also ensure that they become available on phones running Android 6.0 Marshmallow or above.
Until today, it was an open question, but one that was vital for Google to answer. That’s because Google Play is the only reliable system that exists for getting software updates pushed out to Android phones in a timely manner. The other way — full operating system updates — is often fraught with delays from both carriers and manufacturers.
