So ive a mi 3 here. it simply just exploded somehow. and now of coz its not working but still under its warranty. So i have its original came box, its imei and serial number. What i don't have is only the order number. The reason why so is because i bought it from ebay. This is so ridiculous. Why can't xiaomi check its warranty through imei? Samsung and apple can do that. They are now saying they won't provide warranty for me if i do not have order number. Wow. Are you trying to say you can't check its warranty through imei?
