How does rog5 check if it is brand new?

Serial number, fingerprint, record, warranty, accessories.

Detailed steps: 1, depending on the serial number (IMEI). Mobile phone serial number is the same as ID card, and the IMEI number of each mobile phone is unique. Generally speaking, it can be used to judge whether a machine is genuine or not. Whether it is consistent with the previous figures, then look at the IMEI number on the machine packaging box and compare the three to see if they are consistent. If the serial number of the motherboard and the serial number of the chassis are different, then the machine is probably repaired or assembled. If all three serial numbers are the same and there is a network access license, it can basically prove that this machine is genuine.

2. Fingerprint: After getting the phone, the first thing to look at is the phone case. On the screen, where the camera is, see if there are any fingerprints left. Check the data cable interface, earphone hole and strap hole for dust.

3. Record: phone book, phone records, text messages or games, whether anyone has used them, leave a record. If there is, there is a great possibility of refurbished machines. Input: *#92702689# Check whether there is a call record. Check whether there are records in wap and language functions.

4. Warranty: There must be a regular warranty card and invoice, which is guaranteed by the three guarantees policy. If not, it is a refurbished machine, or the warranty period is very short.

5. Accessories: Generally, the original products are one charge and one charge. Refurbishment machine, accessories are not uniform, or not the original factory. So before buying, it's best to know what the accessories of this mobile phone are. Check whether the accessories are marked with fuselage screws and whether the upper and lower covers are concave and convex.
