How to Check Xiaomi Phone When Purchasing

When buying any equipment from hand, you cannot be sure of its excellent quality of functioning, and there are many reasons for this. Someone is lucky, and he takes a thing of good quality, because the seller really does not need it, or he bought something better for himself. But often the equipment is sold after a decent period of use or because it has ceased to suit the owner. We do not claim that you will find a panacea here, but you will learn exactly how to check the Xiaomi Redmi Note 3 Pro upon purchase, as well as find useful information suitable for checking any other Xiaomi smartphone.

The first stage of verification

First of all, the verification method will depend on which device you purchase and for what purposes. Regardless of the situation, we check the seller’s documents for this equipment, and if it is not available for any of the reasons indicated, it is in most cases a fraud or it was simply not important for the owner to store them, which shows his attitude to the equipment and it was unlikely to be extremely careful.

Using the packaging of the gadget, you can easily check the device for originality, we wrote more about this in this article. Be sure to check the IMEI on the phone using the command # 06 # typed in the input menu. The code should correspond to that indicated on the box, on the check and possibly present on the phone cover. Read the “About the Phone” information, check the firmware version, find out about the availability of root, look for programs such as SuperSU, Superuser, talking about the presence of non-original firmware, but this is a completely different topic for conversation.
