THE new NHS Test and Trace app could wrongly tell a third of Brits to self-isolate – and it doesn’t work on older iPhones.
Brits were urged to download the long-delayed Covid-19 contact tracing software after it launched across England and Wales today.
But within hours, flaws in how the app functions has emerged – despite months of setbacks while it was piloted on the Isle of Wight.
According to a report in The Times, one in three people told to self-isolate by the app will have been an error.
That’s because it relies on Bluetooth signals to determine whether someone has been within two metres of an infectious person for 15 minutes.
But this signal can be interfered with by other devices that use Bluetooth – such as wireless headphones – and generate a “false positive”.
Health Secretary Matt Hancock has denied this, telling Times Radio: “No, nobody who gets an alert saying they should self-isolate will have not been in close contact with someone else who has the app.”
