Question About Display Options/Settings On Android Device

[Tex]

Hey @uncledirtnap. Thanks for the question and welcome to the forum.

@uncledirtnap

I’m trying to display a multi slide .odp document on a largish screen Android device and it’s working for the most part except for one thing, when I hit the start slide show button (play arrow) the slides flip 45 degrees and can only be viewed with the device held horizontally (which makes everything smaller and hard to read.)

Hmmm, so if I understand you correctly. You are:

1. Creating an ODP that is “Portrait”.
2. You press the “Fullscreen Presentation” button.
3. Collabora Impress is flipping you Landscape/“Horizontal”.

And you want Collabora Impress to:

• Stay “Portrait”.
• And/or follow the Android OS’s Rotation settings.
  • Rotating phone landscape = horizontal slides.
  • Rotating phone portrait = vertical slides.

And, if I’m reading this correctly… I think the root cause might be… letting Impress’s:

• “Fullscreen Presentation” mode follow Android’s/iOS’s rotation setting

I think that would be a huge step in the right direction.

Hi uncledirtnap, this article called Orientation lock on Android may help.

I tested a basic ODP on:

• Android + Collabora 23.05.5.2 app

and it looks like right after you:

• Hit the “Fullscreen Presentation” button.

Collabora forces Landscape mode no matter what (even if Android’s “Auto-Rotate” is disabled or locked to “Portrait”).

Rotating my phone counterclockwise:

• 0 + 180 (vertical) did nothing.
• 90 + 270 (horizontal)
  • 90 (Left) = the default orientation
  • 270 (Right) = flipped it so slides were right-side up.

@uncledirtnap

The slides in the document are laid out so when I open it on a mobile device like a phone they display vertically like I’m holding the phone.

Hmmm… Can you share/attach a sample ODP?

There are differences between:

1. An “actual Portrait” presentation.

vs.

2. A presentation that just happens to have dimensions that “LOOK like it’s Portrait”.

For example, in LibreOffice 24.2:

There is an Orientation setting which can be:

• Portrait
• Landscape

So let’s say you had a 16"x9" slide. You could have:

• 16″×9″ Landscape
• 9″×16″ Portrait

or, you manually changed the dimensions to:

• 9″×16″, but underneath, you’re actually telling Impress it’s “Landscape”.

(I don’t believe Collabora Impress on Android gives you access to that “Orientation” setting. At least I couldn’t quickly find it while poking around.)
