Network optimisation (very important on the go)

A. Prefer 4G over 5G

5G on Samsung phones can cause micro dropouts.

  • Settings → Connections → Mobile networks

  • Network mode → LTE/4G/3G (Auto)

Test calls for a full day like this.

B. Disable Wi-Fi switching

  • Settings → Connections → Wi-Fi

  • Turn OFF:

    • Intelligent Wi-Fi

    • Switch to better Wi-Fi

    • Hotspot 2.0

When moving, use mobile data only.
