My answer is this.
1. The Mi 11 replacement is a new phone.
2. If the Xiaomi mobile phone we purchased does not match the description, we can contact the merchant to apply for replacement. The phone we exchanged must be a new phone without unpacking.
3. I hope my answer can help you.
Yes, if it is a quality problem, it must be replaced.
If it is such as replacement, it is a conscientious business, it will give you a new one. If it is a black business, you will certainly change a machine for someone else, so buy a mobile phone, you must buy a regular flagship store.
