On Marshmallow, utilize ScanRecord.getDeviceName() to retrieve the local name embedded in the scan record.

BluetoothDevice.getName() is unreliable if the local name is included in a scan response, rather than in the immediate advertising packet.

    @Override
    public void onScanResult(int callbackType, ScanResult scanResult) {
        super.onScanResult(callbackType, scanResult);

        // Retrieve device name via ScanRecord.
        String deviceName = scanResult.getScanRecord().getDeviceName();
    }
