What should I do if the signal of Redmi Note4 stable version is weak?

The number of satellite signals received by the mobile phone is related to the weather, whether there are tall buildings around the location and the strength of the GPS module built into the mobile phone, so it is recommended that the user locate in a location with a strong network signal and an open and unobstructed surrounding environment.

The metal case affects the GPS signal strength. If a metal case is used, it is recommended to remove or replace it with a different material.

When using in the car, place the phone near the windshield, above the dashboard, or in an unobstructed place.

Go to "Settings > Advanced Settings > Location Services" and select "Use GPS, Wi-Fi and Mobile Network" from the location mode. Turning on Wi-Fi and mobile network assisted location can make navigation and positioning more accurate. Check out information such as upgraded navigation software and maps to get the latest road conditions.
