4. Frequently Asked Questions
Q: Why does my iPhone 7 serial number query show "Replaced Product"?
A: It usually means that the motherboard of the device has been replaced, and it may be an official refurbished or repaired machine. It is recommended to check the specific records through GSX.
Q: The IMEI query shows that the device has been activated for many years but the seller says it is a new device in stock?
A: The activation date of an Apple device is calculated from the time it leaves the factory. The so-called "new machine in stock" is mostly a marketing term, and the warranty may actually have expired.
Q: The battery health shows "Repair" but it is actually used normally?
A: When the battery capacity is lower than 80%, the system will prompt and it is recommended to use tools such as CoconutBattery for cross-validation.
5. Purchase suggestions and precautions
1. Give priority to sellers that provide complete packaging boxes and proof of purchase.
2. Be sure to perform a DFU mode flash test to eliminate the risk of hidden ID locks
3. Check whether the Touch ID function is normal. The module is bound to the motherboard and cannot be replaced separately.
4. Note that the 32GB version may cause system lag due to insufficient storage space.
