#145180 — Where are MMS-messages stored in Android 15 ?

I have now spent some time searching for ways to find where MMS-messages 
are stored on my OnePlus 12 mobile with Android 15. There is no end of 
suggestions on how to do this, but nothing I have tested works. 
Referring to menus or file structure not existing on my mobile.
It can't be that difficult, can it?

Best regards

If you check the Android archives, it was discussed in the past.
From my recollection, you need to be rooted, but check the threads.

Are they stored on the phone, or are they just URLs pointing to your 
operator's MMS server?

A good question that I cannot answer. But being just URL's sounds
probable.

https://www.google.com/search?q=android+where+mms+stored

See the AI-generated response which may be sufficient for you to realize
those are stored in a database file which means you won't be looking
inside of them using just a file manager.

https://www.magnetforensics.com/blog/android-messaging-forensics-sms-mms-and-beyond/

Apparently mmssms.db is a SQLite database file, and is unlikely to be
encrypted, so you could look into using SQL[ite] commands to interrogate
the database.  There are SQLite viewer apps for Android, or you could
copy the .db file from Android phone to your PC; however, you probably
still need to know something of the records and their structure to know
on what to search.  An SMS/MMS viewer app, or backup & restore app would
likely know the structure in the database file to present you the
messages stored there, but I've never used one to recommend any.

Are you only looking for where is the database file, or how to peek
inside of it?

I just wanted to get hold of a picture that was sent as MMS as a normal 
picture file, .jpg or whatever. I first tried a long tap on the picture 
in "Messages" , which did not bring up anything. Then my wife showed me 
to use a short tap on the picture, which brought up icons, one of which 
gave a "Share" menu. So simple. Embarrassed :-(

I still get screwed by apps that require sliding left or right to commit
an action.  For one app, I contacted support to ask how to remove an
item.  Their app incorrectly sizes its window, so the bottom is
truncated, and that's where they put the Remove button, so it is not
visible.  The rep said to slide the item to the left to see a Remove
option.  Simple, but I wouldn't have thought of that since it was a new
feature in a recent version.

Glad you figured out where media is stored for your messaging app.

As far as I'm aware, each messenger can save the photos to sd0 storage.

Mine, for example, are auto-stored in /sd0/Pictures/Pulse/{image.jpg}

You can find where thigns were with lipstick, talcum powder, or smoke.

For security reasons *all* Apps store their data in their *private*
storage by default which is *not* accessible with file managers if you
don't have root access. If this would not be the case, *all* apps which
have the "read files" permission could read *all* your data, including
all your MMS, SMS, contacts and so on.

Gaining root access usually also means you need to unlock the bootloader
of your device and install at least software like Magisk. This is often
not possible without wiping the whole device and even installing a
custom ROM.

It's weird isn't it!  It's only on mobile phones that this strange
system is applied.  On any computer system access is controlled for a
**user** and programs run by that user can access any data that is
readable by that user.  The computer model for access seems much more
reasonable to me.  Surely if I have (say) an address list I want to be
able to use that from other programs on my device, it's my data, why
should I be prevented from using it from another program?

Think about it. Even you can find that out. This system is smarter than
you think given the disaster prone Windows.

What 70%+ on this planet are using as desktop-OS and create nothing but

I am not sure this is fully true. I make backups from Linux via USB 
cable, and I get the WhatsApp store, the photos, many things. There are 
just a few directories from the system that are not readable.

  Indeed. The same is the case if you connect the Android device [1] via
a USB-cable to a Windows system. All normal folders and specifically
\Android\* (data, media, obb , obj) are accessible in (Windows) File
Explorer. Of course this isn't a scurity/privacy issue, because you need
physical access to the device and the device must be unlocked.

  As Chris Green noted, the Android model, of not letting a user access
their own data, is rather silly for users used to normal/real computers.
But it's probably the result of the design choice to only have a normal
user and not some kind of administrator/root. Whether that design choice
is a reasonable/sane/etc. one, is left up to the reader. As Android is
Linux-like under the hood, you probably can guess my position! :-)

[1] Android device: smartphone, tablet, etc..

And "normal folders" are *not* private app storage folders. For example
you can *not* read the contact database this way.
