A mini app can take the whole screen, including sideways, instead of sitting in a panel over the chat. Games get a proper landscape canvas and dashboards get room for a table.
What goes away with the panel is the Telegram frame around it — and that frame was doing quiet work you probably never noticed.
What you will be able to do
- check_circle Use a mini app in full screen and get back out.
- check_circle Know which apps genuinely need it.
- check_circle Notice what disappears along with the frame.
- check_circle Keep the habit that makes it safe.
The panel gives way to the whole screen, and the app can hold it in landscape.
fullscreen The frame was the context
In the ordinary panel, a mini app is visibly a guest. Telegram's header sits above it with the app's name and a close button, the conversation is behind it, and everything about the arrangement says this is somebody's page being shown inside the app you trust.
Full screen removes all of that, which is exactly what a game needs and exactly what makes the trust question harder. A page occupying the whole display with its own layout can look like anything it wants to, including like part of Telegram, and there is no longer a border making the distinction for you.
Nothing about the app's access changes — it is the same web page with the same limits it had in the panel. What changes is what you can see about where you are, and that is worth compensating for by deciding what an app is before letting it take the screen rather than afterwards.
Where it helps and where it does not
The last tab is what to do when an app takes the screen and should not have.
sports_esports What it was built for
table_chart When the content is wide
desktop_windows A window, not a takeover
close_fullscreen Leaving, and what leaving means
Full screen earns its place for games and wide content. Judge the app before the frame disappears.
settings Using it
- Decide about the app at the listing Before it opens, not after.
- Let it take the screen for games and wide content Where the space is the point.
- Turn the phone sideways If the app supports landscape.
- Leave immediately if credentials are requested Whatever the page looks like.
- Return to the panel to reach the chat The way back is always there.
- Close anything you signed into Minimised means still running.
This page is one of them taking the whole screen. The curriculum step is what a mini app is underneath: a web application inside the client, what it can and cannot reach, and where the boundary between Telegram and a developer's server really sits.
