Nhs Covid App

[Misty P]

Evening Everyone!
Today I got a notification on my NHS covid app that I had been in contact with someone who has tested positive.
This alarmed me greatly.
It tells me I need to isolate for 6 days. The isolation period is 10 days from your contact with the person, so I'm guessing my contact was on Sunday.
I went to only one place on Sunday that was outdoors and cannot see how, at any time I was within 2m of someone for more than 15 minutes... which is how the app algorithms work.
The only thing I can think of, during my time out, my phone battery died. Could this have affected the Bluetooth communication within the app, letting it think I was still in the vicinity of this person when, actually I was not??
Cheers.

I will add.. I fully intend to self isolate for the recommended time period.
Its just I was with 3 others and none got a similar notification...

Maybe be one of the three has tested positive

Isolation periods include the day of the contact, so Monday was 'Day 1', which was also the contact day.

In my uninformed opinion of the app, I would have thought that a dying/dead battery would result in contacts not being noticed rather that non-contacts being created.

Yes the contact must of been Monday when phone was working
