How can I get my iPhone 12 back to normal cause it’s in demo mode
iPhone 12, iOS 14
It is not possible.
Apple doesn't sell demo iPhones.
A Demo iPhone is a Property of Apple.
This iPhone cannot be used and is not for sale.
Return it to a nearby Apple Store or an Apple Authorized Reseller in your region.
Demo iPhones are sold on the black market, obtained when breaking into an Apple Store or an Apple Authorized Reseller.
If you have bought it from some one, ask you money back.
