There may be a firewall/NAT issue, but first you should try using a newer (3.17.1) version of iperf3. Android pre-built versions are available at: https://github.com/davidBar-On/android-iperf3.

Even though Android is not an officially supported platform, I'm pretty sure we did some changes since the version you're running to improve Android compatibility.
