Question to the Department of Health and Social Care:

To ask Her Majesty's Government what proportion of smartphones currently in circulation in the UK which are fully functional with (1) the NHSX COVID-19 contact tracing application, and (2) the new contact tracing application currently under development that uses the Google and Apple exposure notification application programming interface.

The NHS Test and Trace app which is currently being trialled will require smartphones to be running Apple iOS 13.5 and above or Android Marshmallow 6.0 and above. Estimates show that 82% of Apple smartphones and 91% of Android smartphones in the United Kingdom run or are capable of running these versions.
