Long press back button to kill app without root?

Hi,

Is there anyway to long press back button to kill app without root?

I like this feature but the Barclays banking app force closes on my rooted 5.1.1 with xposed.
So I need to unroot and uninstall xposed for this app to work .:mad:

Thanks

Stuck on setupwizard and I cannot press Next button

My phone stuck on setupwizard after I wiped data/factory reset. The Next button is gray and doesn't work. Does anyone can solve this? Thanks in advance:)
