seems to have been happening in the beta too.
Seems like Android 14 handles messages differently...

On the Reddit thread that Paz9 linked to, there is this comment regarding SMS Backup & Restore. The user said if you look at the XML you will see sub_id="-1" and changing this to 1 should allow the restore to work properly.


I tested it out with a single backed-up SMS thread and it did not restore anything. I then tried changing all the sub_ids to -1 and all of my messages were restored properly. So I had the opposite of what this user mentioned but it led me to a solution.

ok so if its -1 we change to 1 and vice versa?
pretty strange it worked after you changed sub ids to -1 and in the tread it states the opposite.

i guess we can figure out the messages that actually do get restored and match the sub ids to them - ill give this a crack tonight.

@demonjrules just to confirm that you changed all subIDs to -1 on your pixel 8/pro? suspect it might be related to different phones too.
i will give this a crack later tonight.


can anyone else confirm the findings?

not sure if that is the case but I am just saying that is what worked for me, and yes I do admit that it is strange that it is the exact opposite of the Reddit commenter. All the messages that were missing from my XML file were set to a value of 1 while the items that did show up were set to -1. So take a look at your XML and find a known message that is missing from your restore and change it to the opposite of what the sub_id is currently.

I have a Pixel 8 pro to answer your question. Before I saw your comment, I originally did a full backup/restore from my Pixel 3A (over 200k+ messages) and it took over a day to restore so I was pretty upset seeing a lot of SMS/MMS missing. So what I did was make a backup of just 1 thread (77 messages) on the Pixel 3A, copied the XML to my computer, changed the sub_ids, copied the new XML to the Pixel 8 pro, and restored that and I saw the messages that I confirmed were missing from the previous full restore.

Edit:
I don't know how I did not notice this comment before but this person also had success by changing the value to -1
