Not it.splitify?
I think Splitify might have been it going by the screenshots. The problem is when I removed it, it didn't actually remove it. I just tried to install and remove it again with no luck. Cydia shows it's gone but I can still enable the split screen.
Ok, I booted the iPad while holding the volume up button. No mods show up in the settings pane. The split view still works. Does this mean it's something that is built into 9.0.2?
After searching Google, this is called slide over and is enables on the iPad Mini 2 and later iPads. I'm trying to find a way to disable it now. I don't thikn there is a way though.That means the split view you're experience isn't due to a tweak
It is probably a feature of 9.0.2
I thought it was only for the iPad Air 2 but maybe I'm wrong
