TL;DR
Google Signals uses data from users signed into Google accounts to provide cross-device reporting, demographics and interests data, and more accurate user counts. Enable in Admin > Data Settings > Data Collection > Turn on Google Signals. When enabled, GA4 can recognise the same user across devices (phone, tablet, desktop) if they are signed into Google.
