How to add a multitasking button to the LG G Pro 2

Good news, everyone! LG switched to on-screen buttons for the G Pro 2 (be sure to read our preview of the phone), just like it did with last year's G2. The bad news? It still has a legacy menu button — and you can't get rid of it.

There is a glimmer of hope, however. LG's made it so you can add up to two more buttons — and that includes multitasking. (Or as it's more correctly know, a button for returning to recently used apps.)
