bug (YouTube): Cannot open channel pages on tablet

[j1elo]

Bug description

It's impossible to open any channel's main page on the YouTube app. When trying to do so, an error shows up that says:

There was a problem with the server [400]

However, doing exactly the same in parallel with a phone, it works fine and the channel's page is opened. This has been tested in multiple videos, and the same error always happens.

Steps to reproduce:

• Open patched YouTube.
• Tap on any video.
• Tap on the channel's name, below the video's title.

More details:

• Tested with a clean install (no settings changed from defaults) on both tablet and phone.
• The network and the devices don't have any kind of ad-blocker such as AdGuard.

Thanks a lot for this app and for all the effort it takes to make it... I only hope to help make it a tiny bit better.

Merry Christmas!

Try repatching and exclude wide search bar patch.

Try repatching and exclude wide search bar patch.

Thanks, will do.

The error is caused by "Tablet layout" patch. I am unsure why, because the code flow should not differ from stock when the setting is untouched.

[j1elo]

Confirmed. Had to go to Settings > ReVanced > Layout, and turn "Enable tablet layout" ON.

This setting is off by default, which causes the issue here. Upon enabling tablet layout and restarting the app, the Channel page shows up successfully

(just for completeness: this also solved https://github.com/ReVanced/revanced-patches/issues/2536 and https://github.com/ReVanced/revanced-patches/issues/2538 for me).

Not sure if the tablet layout patch could be improved somehow, e.g. to be enabled by default when a tablet-sized screen is detected. But, technically speaking I'd consider this a non-bug, just a default configuration issue. Maybe it merits some doc for users to know about it.

[j1elo]

Wait I mixed up issues here.

[oSumAtrIX]

It is a bug as the toggle should force tablet layout when enabled, but not disable it when not enabled.

[j1elo]

So here's the summary of all findings so far:

• The 3 tablet issues were: Watch History doesn't show up, Cannot open channel page, Cannot expand video description.
• Turns out all 3 issues are solved by including the "Enable tablet layout" patch and enabling it on the ReVanced settings. So it makes sense only a single issue is left open.
• All 3 issues still happen if "Enable tablet layout" patch is excluded when patching the app. So this patch is needed for the tablet, and the option must be enabled.

[oSumAtrIX]

Please figure out which patch causes it and report back:

[ttimasdf]

go to Settings > ReVanced > Layout, and turn "Enable tablet layout" ON.

This workaround also works for me
