When you go to Xiaomi official website, there is a special mobile phone security code query, or after official website vip verification, almost both of them can pass. I have some other inspection methods here. Try it yourself. First, use the recovery mode to identify the way to enter the recovery mode: M2 seconds, press and hold "power button+volume plus" when the MI sign appears on the screen, and release the power button to continue to press and hold the volume plus. You can't put down the genuine mobile phone and the genuine UI until you enter the recovery mode. What you see is the recovery mode of Xiaomi mobile phone. Students who choose cash on delivery can install batteries first to see if they are the same as those in official website. If it's not this picture, it's probably fake, so choose to return it decisively. I have basically tried this method. Xiaomi can't brush the RE of a third party at the factory, so if the recovery mode of the mobile phone you bought is different from this, then ... Second, the method of using the quick start mode to identify the way to enter the quick start mode: Mi2s, press and hold the "power on button+volume reduction" in the closed state to enter; Just like the recovery mode, enter the quick start mode. If the mobile phone you bought is different from the fastboot picture on official website, you will be miserable! Third, use Ann Bunny's running score to check. First download and install Ann Bunny's mobile phone evaluation. For the running of M 2S, it is recommended to run in performance mode. If the running score is above 24,000, it is normal. If your running score is too low, you should carefully verify the authenticity. Fourth, check the RAM size. You can install "Android Optimizer" to check the RAM capacity of your mobile phone and open the machine check assistant. The meter 2S is 2G memory. Fifthly, after Xiaomi official website verifies and logs into Xiaomi Community, click "Xiaomi Authentication" in the upper right corner of the page for authentication. After successful certification, he will become a certified user of Xiaomi community and get a medal of the corresponding model. (SN, IMEI number can be opened on the battery and can be seen in the battery slot. Sixth, other methods verify that Xiaomi mobile phone 2S has no keyboard light, and the three keys on the mobile phone will not light up. If you really buy Xiaomi 2S with the keyboard light on, this joke will be big. If it's fake, the IMEI numbers of two millet purchased by the same Taobao store may be exactly the same!
