If you have not updated your app to v3.9 or higher, you may get notifications saying “Possible COVID-19 Exposure”. These are generated automatically from the Apple or Google technology the NHS COVID-19 app uses. Read more about how to update your app.

Your phone will tell you whenever it detects that you’ve been near someone who has tested positive. Sometimes, you may still receive this message even when the app’s risk-scoring algorithm has decided that you were not close enough, for long enough, to be at risk.

If you receive this notification, you will also receive a second notification from the NHS COVID-19 app. This will either tell you to self-isolate or you’ll get an “Exposure Check Complete” notification, in which case you do not need to do anything. If you do need to self-isolate, this will always be visible within the app as a self-isolation countdown timer.
