Why is .pptx hard to open on a phone?
- Slides need layout, fonts, and media handling, which can be inconsistent outside Office apps.
- Animations and transitions are not useful in a lightweight phone preview.
- A quick slide render plus text and media summary is often enough to identify the deck.
What OpenOnPhone does not do
