  4. Reset network settings.

    Erroneous network configuration on the phone can also cause some conflicts and could be the main reason as to why calls are dropping. To clear this out, you can do a network reset.

  5. Remount the SIM card.

    In some instances, the problem is directly attributed to a problematic SIM card in use. This is usually the case if the SIM card system gets corrupted and your device suddenly failed to read the SIM card. This then results in unstable network services, network errors and calling issues.
    To fix the problem, remounting the SIM card is recommended. 
    To do this, you will need to use the SIM ejector tool that came with your phone. If you don’t have it, you can use a small paperclip instead. 
    Before removing the SIM card, be sure to turn off your phone. This is highly recommended to prevent causing any sort of damage to the SIM card or the phone itself.
    After turning the phone off, insert the SIM ejector into the small hole on the SIM tray. The SIM tray is located on the top-left side of the phone. 
    Gently push the ejector until the tray ejects and then remove the SIM card from the tray. After a few seconds, place the SIM card back into the tray in the same orientation before you remove it. Secure the SIM card in place then gently push the SIM tray back into the phone. When the tray is locked, turn the phone back on and wait until it obtains a stable cellular signal.
    Then place a test call and see if the problem is gone.

What to do if the problem continues?

Removing any protective casing from the phone may also be necessary. Some phone cases, particularly third-party casing may not actually fit and therefore can block the network antenna from getting a stable signal. As a result the signal keeps disconnecting and calls keep dropping.

The same thing can happen if you’re using the phone in an area where the cellular network signal is too weak. The weaker the signal the phone gets, the more likely it gets disconnected. In this case, there’s nothing much can be done but to make the call whenever your phone is already getting a strong and stable signal.

Meanwhile, if the problem started after the phone got wet or dropped accidentally, hardware damage is likely the underlying cause. In that case, a technician’s aid would be necessary.

And that covers everything in this troubleshooting guide. Please keep posted for more comprehensive troubleshooting guides and tutorials that would help you make the most of what the new Samsung galaxy s20 has to offer.
