[v2026.2.0-latest +1](https://github.com/discourse/discourse/commit/ce66d301eda195966590215d17f9ce8052c32f49 "ce66d301eda195966590215d17f9ce8052c32f49") seems to have introduced (at least for my installs) that mobile rendering only shows threads and content on half (left half) of the screen when foldable is “wide”
Header, footer, and column headers (“topic replies, views activity”) are all full width
Tested across 2 sites, same results. Not an issue here on meta.
Same issue if loaded while folded or unfolded
MAY NOT have been 2026.2.0, I only update once a week

This might have to do with the changes to deciding desktop/mobile views based on viewport size 🤔.

There was another topic about the change to choose mode based on screen width instead of the separate mobile mode a while back:
> [@Improving automatic switching of mobile/desktop modes](https://meta.discourse.org/t/improving-automatic-switching-of-mobile-desktop-modes/384280/3):

> Folding phones is one of the reasons that we made this change. The feedback we’ve received elsewhere is that folding phones should show more on the screen when unfolded. Showing the ‘desktop view’ there is intentional. Is there a particular part of the UI which didn’t work well when the phone was unfolded?

Moved this to UX as it’s functional, just not optimal.
The elements are probably using a different (type of) media query.
I don’t have a foldable so might be more tricky to test/repro than to fix. @Falco Don’t you? If so, ping me for a CSS collab xD

Here is what I see on my OnePlus Open:
Everything looks good to me.

Correct, no problem here on meta, problems on self hosted (2x sites I run). Samsung fold

The best thing to do is share your site URL so people can take a look.
If you don’t want to do that, you can try disabling customisations until it works.

We do not provide individual support in PMs, sorry. That’s reserved for our hosting customers.

I can understand that you don’t want to share your forum publicly. Maybe you can find another forum with the same problem on [https://discover.discourse.com/](https://discover.discourse.com/) and share that.
You can also try the different themes here on Meta and on [try.discourse.org](http://try.discourse.org). Though, since [safe mode](https://meta.discourse.org/t/53504?silent=true) didn’t help, it doesn’t seem that likely it will help.
Perhaps that is the change that caused the problem. Is that within the week between your updates?

Hello 👋
The issue you’re seeing is caused by a conflict between the _new_ viewport-based style and the _old_ mobile view. It looks like the `Viewport based mobile mode` site setting is currently disabled in your admin.
To fix this, simply enable the setting under your site settings. This should resolve the layout conflict.

I didn’t ask for support via PM, I asked to send you the URL and login info as one of the sites is non public and requires login to view.
Thanks though

I’ll give this a try. Hopefully this does not re-introduce the error I reported back in October
