Locus Map processes location and elevation gain from the data it receives from your phone GPS. If the data are incorrect or contain massive deviations, the resulting location fix and elevation gain are incorrect. Locus Map, however, offers a few methods on how to limit these deviations.

Open Locus settings > GPS&sensors and set the following

• Location filter > select medium or heavier filter
• Google Services assisted location > turn it ON
• Altitude manager > settings tab > SRTM data - select Optimize GPS values or Replace GPS values
• Altitude manager > settings tab > Pressure sensor > turn ON (if available)
• Altitude manager > settings tab > Altitude filter - select medium or heavier filter
