Devices now find each other on networks where discovery used to fail — including over a phone's own hotspot, which never worked before.

• New broadcast-based device discovery, running alongside the existing method
• Send by address: reach a paired device by typing its address when discovery can't get through
• The Receive screen now shows the address other devices can reach this phone at
• A fixed transfer port, so firewall rules and typed addresses stay valid between runs
• Wi-Fi Direct now explains that it can't run while your hotspot is on, instead of failing with an unhelpful error
