My First 6 Months Trying Out Xiaomi Smart Phones Long story short:Bought Phone & Had Nightmare with delivery.Phone riddled with Adverts.Phone speaker broke after 1 month.Phone warranty process not straight forward.Replacement phone seems to be very laggy.Few months later rear battery cover cracked to a light drop.Asked if I could purchase a replacement rear battery cover from them.They wrote back basically say NO! and highlight very abruptly my: "Warranty No Longer Valid!" (because of a cracked battery cover!?!).. My first experience with Xiaomi has been very poor to say the least!...I will not be purchasing another phone from them again.
