All contacts transferred in about secs
I couldn’t find a way to transfer my contacts to my new iPhone whitout having to factory reset it, nor anything else that worked. I looked up the app store for an app which might work, and I found this one. It took about 4 seconds to download it, another some to back the contact up and via Airdrop it took just a click amd every contact has been transferred :) Very easy and super fast, without the need to resetting your phone.
