A short and simple guide to find out if you have the tracking “App” for COVID-19 and therefore remove it from your Android smartphone. It doesn’t work on all devices. 01/06/2020 update: it seems that in some smartphone models there are problems of synchronization of contacts with the Google account. If you are able to do it you can try to install a newer version of Google Play Services (but not the COVID-19 one) via apk, but I fear at this point that in a short time we will be forced to update if you don’t want to give up some functionality.
