I bought the Xiaomi 14 Ulra model from the company website, the phone sold as global edition was released as a Chinese model. Then the product did not receive GSM signals and did not support 20 band. I sent the product to the warranty, but the warranty told me that there is no mainboard model and hardware support, unfortunately there is nothing to do. I want to send the product back. They are threatening me and telling lies after lies to avoid giving me my money. Be careful when buying products from this company, the product comes differently and do not be a victim.
