The port scanner shows some open ports even though I'm sure they are closed

This typically happens when there's some proxy/firewall between you and the scanned device. For instance, some cell network providers proxy all network requests so all ports appear open. What happens in this case is that when the port scanner tries to connect to the scanned device, the connection attempt is captured by the proxy so in fact, you are connecting to the proxy and not to the remote device (the proxy then connects to the scanned device on your behalf and forwards the data to you).

Unfortunately there's nothing which can be done in this case - the proxy in the middle is completely invisible to Network Analyzer and cannot be detected.
