t's great to mention that the Galaxy S21 rear camera replacement we are selling is taken from an original unused Samsung phone. This means that the replacement camera has been manufactured to the same specifications and quality as the original camera, ensuring that it provides the same level of performance, functionality, durability, and same high-quality lens. 

Additionally, using an original camera for the replacement can also help maintain the resale value of the phone. If a customer decides to sell their phone in the future, having an original camera replacement can help increase its value, as it shows that the phone has been well-maintained and cared for.
