It looks like I mostly reproduce this when I'm under LTE coverage.

Hey Bevis,

Thanks for the log.
After investigating the log,
I found a regression of bug 992772 that cause the MmsService sent the request to the network even DNS query was failed. (An abuse of promise that was unexpectedly fulfilled after rejected [1])

I'll take this bug to follow up.

Hi Lissy,

In addition to the regression I found,
there is one more problem about why the DNS query is failed.

Is it possible to capture the tcpdump and the adb logcat with ril/mms/network debug flags enabled for further clarification or Is there any QA in France who is able to help on this?

Thanks!

No it's not. I don't reproduce that often and when I do I cannot get tcpdump often. Besides, I did enable RIL, Network AND MMS in the logs I shared.

Never mind.
I'll fix the regression I found firstly to fix the wrong identification of the mms transaction result between sender and receiver.

Maybe you can split through more debug for the DNS issue, so that we can have a clue next time it happens with just the device logs.
