Affected app version

1.1.4

Affected Android/Custom ROM version

OxygenOS 15

Affected device model

Oneplus 12

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Another individual sends an image, voice message, or very long text message
2. An error message briefly pops up on screen ("Error: Could not download MMS", or something similar) and disappears. This happens both with app in foreground and background

Expected behavior

MMS content should be downloaded, as in other SMS applications. Any error message of this type should be tied to the conversation the MMS was intended to be downloaded to, and should be reviewable, rather than just being a general static message that disappears in ~1 second.

Actual behavior

Another individual sends an image, voice message, or very long text message. An error message then briefly pops up on screen ("Error: Could not download MMS", or something similar) and disappears, without any sign of who it was coming from and no way to retrieve it.

Screenshots/Screen recordings

No response

Additional information

All bundled AI services on the phone have been disabled or removed, as well as bundled Google apps aside from Drive, Gmail, and Maps (i.e. Google Messages was the original default SMS app).

Considering the fact that you also can't send MMS (#255 (comment)) - does MMS work in other apps (e.g. Google Messages or QKSMS), or is it only in Fossify Messages? There's a chance you've disabled too many services, or have misconfigured carrier settings.

[puutelias]

You are correct, it was mainly APN settings. I wrongly assumed that my SIM card would have provided the correct settings (i.e. defaults after network settings reset were incorrect). I also had to reduce my outgoing size to solve the sending issue mentioned elsewhere.

I am still having a brief error message thrown when another person sends me an MMS message (the message is different now, too long to fit on the screen), but the error doesn't appear to stop me from receiving the MMS message.
