Understanding Manufacturer Defects
Manufacturer defects are flaws that occur during the production process. These issues are typically present from the start and may affect the phone’s functionality or appearance. Recognizing these defects before buying is crucial to ensure you get a reliable device.
Common Manufacturer Defects to Watch For
