I tried to register my Rog phone And it tells me that the serial number is incorrect, I used copy paste and it still doesn't work, I went to the website but it also asks for the date of purchase, but I got the phone from a store Second hand, what could I do,

Maybe because its second hand. I don't know there warranty policy.

Could be that the phone was already registered before? That's why it doesn't allow you to re-register it. You may ask the official asus stores near you

it happened to me too, and I repeated it several times but after I checked in the app, it was already registered in my account
