Are tired of pressing the home button hard twice just to switch apps in the multitasking bar? Do you want to try it on the screen instead?
Then, these steps are just right for you.
First, activate Assistive Touch,
Go to Settings -> General -> Accessibility -> Assistive Touch -> On
1. Touch the white circular disc that appears on your screen.
2. Double touch the Home icon.
3. When the multitasking bar appears, wait for the Assistive Touch menu to return to its original position. (This will take a second.)
4. Select the app you want to switch into.
And that’s it. You can also move the circular disc around your screen by dragging it into its new location. If you want to deactivate Assistive touch, just go to the Settings app.
