Recently, many mobile phone brands have launched their latest models, vivo Y77 is the latest Y series model launched by vivo in July this year, I believe there are many friends who have been fans of this mobile phone! In order to facilitate everyone's better purchase, Xiaobian has sorted out how to check whether this mobile phone is a refurbished machine below!

 How to check if vivo Y77 is a refurbished machine

 1. How to judge the second-hand phone:

The packaging box of the second-hand mobile phone is simply packaged in a white box, while the new machine is packaged in a color box, which can be judged according to the introduction of the seller and the packaging box.

Warranty time: second-hand mobile phones do not support return and exchange services, do not enjoy the purchase of "extended warranty, broken screen treasure" and other protection service rights, the warranty period of the mobile phone is calculated according to the first sale date of one year of warranty duration, you can enjoy warranty or repair services at vivo national official service centers, the specific warranty period can be viewed on the electronic warranty card page (or log in to the vivo official website - service - find authenticity page to view).

 2. The method of judging the refurbished machine:

Purchase channels: personal, offline informal stores, online stores without credit guarantee and other informal channels;

Outer packaging and instructions: The packaging and instructions of the regular new machine are beautifully printed, and the fonts and images are very clear and hierarchical. The packaging of the refurbished machine is mostly simple imitation, the font and image are rough, and the printing handwriting is blurred; Some refurbished machines are in their original packaging, which can also leave traces of use, such as wear and tear.

Network access permit: There is a watermark on the real network access permit, and the color of the surface is dark and light, thick and thin. Most of the fake network access permits are copied, and the surface color has not changed.

Observe the appearance: the new machine shell is tightly jointed, the gap is flat and smooth, and there are no burrs. The refurbished machine generally adopts the imitation original shell, the gap is uneven, there are burrs, and the upper and lower parts of the shell are prone to close tightly, leaving a large gap.

Headset and data cable interface: Due to the long-term plugging and unplugging of headphones and data cables, the interface of the refurbished machine will have scratches that are difficult to eliminate.

Charging test: There are many refurbished phones that will lose power after a little longer charging time, so you can try charging your phone, and it is better to charge it for a longer time.

3. If you still can't judge through the above methods, you can bring your mobile phone to the customer service center for testing and processing (customer service center address: enter the "vivo official website/vivo mall" APP--mine--service outlets/after-sales outlets--select the province and city for inquiry).
