Immuni - Italian Covid-19 tracking app
Version 1.5.0.1512286 of 17.09.2020 is the official exposure notification app of the Italian government.
I’ve tested this app on the rapid on a Galaxy A3 2017 ‘A320FL’ with @harvey186’s /e/ OS ROM Q-GSI with microG Services Core version 0.2.12.203315. It looks like the app works with microG Services Core version 0.2.12.203315.
To this must be said: I’m neither Italian nor located in Italy, but I was still able to install the app from the Aurora Store (from F-Droid Store). I had to take pictures with a separate camera because the screenshot with the A3 2017 was not allowed.
