Fairphone Dropped Call Symptoms

Verify the symptom by observing if calls end abruptly without input, if audio cuts out in one or both directions prior to disconnection, or if the device fails to initiate a connection, showing 'Calling...' before terminating. Confirm the issue persists during active voice calls by checking if the signal indicator drops from '4G/LTE' to 'E', 'H', or 'G' simultaneously with the disconnection.
