How do I force my iPad to open apps in a full window as default
This is a bit hard to explain, but a few days ago (no update) will open up an app in a window mode, not using the full screen. I notice that there is a small semi-circle in the bottom right of my screen.
By pressing and holding this semi-circle, I can resize the apps window space.
This started happening a few days ago. While I don't mind this function at all, it's annoying because often when I switch or open up an app, it doesn't take up the whole screen, but about 80%. I notice that I can easily select other apps that are open since the icons are visible, but I would rather the default setting that the app takes up the while space.
I can force the app to take up the whole space by pressing an holding the semi-circle and then pulling it down and to the right, but it's quite annoying to have to do this all the time whenever I switch an app.
So, I guess my question is how can I force my iPad to open apps using the full screen and not just a partial screen?
