1, we don't recommend that you buy Xiaomi mobile phones in unofficial sales channels, so as not to cause unnecessary losses to you.
At present, Xiaomi mobile phone does not have any official offline stores and telephone ordering business, and the only sales channels are www.xiaomi.com and official website. And the contract models sold in the local Unicom telecom business hall.
At present, Taobao and the market have a large number of counterfeit millet phones with modified IMEI numbers, which cannot be verified and identified by official website. Please be careful. See news interview post/thread-6919533-1-1.html.
2. Your invoice is not the invoice of Xiaomi mobile phone.
3, identify the authenticity:
You can enter two modes: recovery (power off, press and hold the volume up+power on key to enter recovery) and fastboot (press and hold the volume down +Mijian+ power on key to enter) to see if it is the style of MIUI system. See/thread-3104435-1-1.html for the MIUI style. Counterfeits are usually robots with exclamation marks or a few lines of English.
A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
