I'm happy to help with all of this, GramGram! First, I have this link (https://bit.ly/3oa56ug) to the full terms and conditions of the manufacturer warranty for this model. While we do recommend registering your products, it is not necessary to receive warranty coverage. Registering mainly helps us in confirming the start date of your warranty, but a purchase receipt with this information can also be used if necessary. If you'd like to go ahead and register, you can do so on the Samsung website after creating a Samsung account. Or, if you'd like, you can just message us and we'll take care of everything. Just reference ticket number 1143301469, and contact us through Facebook Messenger: http://m.me/samsungsupport; or Twitter: https://twitter.com/messages/compose?recipient_id=18768513. ^Jecca
