Is there any way to bypass an activation lock connected to an email on an iPhone 6s?

So, i bought an iPhone from somebody, they reset it to new, but never deactivated their iCloud or whatever.

Added (1). Is there a way to remove it if you can't bypass it?

It's not new if it's refurbished.

Nope. ICloud lock is an anti-theft feature that can't be bypassed. A security system would be pretty useless if you could easily bypass it, wouldn't you think?

If you can still get ahold of the person who sold you the phone, ask him/her to remove that iPhone from his/her iCloud account. However, chances are high that you bought a stolen phone…

Get hold of them and get them to deactivate their iCloud.

You should always check that before buying it → http://www.justtext.com/messageboards/20150103123508.html?y1
