How to stop this icon from appearing on the taskbar?

I'm not sure how to explain this. I recently upgraded my iPad. And this thing wasn't happening before. Let me show it with a screenshot:

Say, if I close one app and want to go to the Mail icon. I will try to touch "Mail" (blue one, second from the left) at the bottom row. But right when I'm doing this, that new icon appears on the right (marked with a red arrow) and the whole strip shifts to the left making me click the App store icon instead of Mail.

This is VERY annoying!

How do I stop that icon from appearing on the right?

Solution 1:

That's the "handoff" feature. You can turn it off at: Settings > General > Handoff.

When you turn it off, that device can't send or receive handoffs. A little bit more info.

You could also use a different iCloud account on your phone/iPad if you wanted handoff to work between a Mac and one device but not both iOS devices, but more than one iCloud is a hassle, so disabling handoff entirely is much cleaner.
