Group MMS replies include own number

[hhff]

DESCRIPTION

For whatever reason, my device doesn't known it's own number. If you navigate into:

System -> About phone -> Status -> Sim Status

The "My phone number" section reads "unknown". This is a T-Mobile SIM card.

As I understand it, this means that TelephonyManager#getLine1Number returns blank.

STEPS

1. In the above precondition, send a group MMS to two or more recipients
2. Receive a reply from one of the recipients

EXPECTED

The reply should be in the same "thread" as the original outgoing group MMS.

OBSERVATIONS

The reply was instead put into a new thread, with my own number as an extra recipient:

I also have this issue. I'm on lineageos 16 / oneplus3. My phone knows about both of my SIM cards and both of my phone numbers, though.

Hmmm interesting - what phone do you have @hhff?

[hhff]

@moezbhatti we're an OEM, so this device isn't released yet.

FWIW - this is the solution we implemented:
klinker41/android-smsmms#156

We haven't had this merged yet as there's still one last change the repo owner would like. I'm hoping to finish that PR off on the weekend!

This happens to me. H3123 LineageOS 16.
I should add that I can see my own number.
