Samsung Hides Galaxy Wi-Fi Tool That Flags Signals Below -70dBm

Summary
Samsung’s built-in Connectivity Labs can map weak Wi-Fi spots on Galaxy phones, marking signals below -70dBm and helping users find dead zones room by room.
Five taps on the Intelligent Wi-Fi version number unlock the hidden feature in One UI, after which Home Wi-Fi inspection tracks selected networks as users move around a home.
The tool also scans nearby channel congestion, compares 2.4GHz and 5GHz conditions, and can guide router channel changes when crowded airwaves are slowing connections.
Additional diagnostics include signal-strength graphs, connection-change logs, website network tests, and a 1-week usage summary showing bands, protocol versions, and upload-download totals.
The feature gives Galaxy users a built-in alternative to third-party Wi-Fi analyzer apps, surfacing unusually detailed network data from Samsung’s own settings menu.
