Please answer these questions before submitting your issue. Thanks!
I'm trying to ship a golang binary inside a android app
conn, err := net.DialUDP("udp", nil, raddr)
if err != nil{
//xxxx
}

size, raddr, err1 := conn.ReadFromUDP(buffer[:])

It's working。but when i use conn.Close()，err1 don't return error，it's waiting for ReadFromUDP
iPhone is ok.

There is not enough information in this report to diagnose the issue. Please include a complete, self-contained code example if possible, ideally as a runnable program in the playground.

Apart from the self-contained example, is this reproducible on a regular Linux?

I also use it on android and iOS，iOS is ok，but android don't return error。I guess that the bottom of Android don't return error code

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
