## IMPROVED Description
Đây là một ứng dụng iPhone mà mọi người đều có thể sử dụng, hỗ trợ các dòng iPhone từ 10 đến 15. 
Ứng dụng được dùng để kiểm tra xem điện thoại của khách hàng có gặp vấn đề về chức năng hay không; vì vậy, chúng tôi sẽ sử dụng GPS, Wi-Fi, Bluetooth… và cuối cùng kết hợp với các hạng mục kiểm tra thủ công để đưa ra mức giá thu mua điện thoại.
Ứng dụng này hoàn toàn miễn phí, không có bất kỳ nội dung trả phí nào và cũng không có bất kỳ lỗi nào. Kính mong quý vị sớm xét duyệt, vì ứng dụng này rất cần được phát hành gấp.


English
This is an iPhone application that everyone can use, supporting iPhone models from 10 to 15. 
The app is designed to check whether a customer’s phone has any functional issues; therefore, we will use GPS, Wi-Fi, Bluetooth, etc., and finally combine with manual inspection items to provide a buyback price for the phone.
This application is completely free, with no paid content and no errors. We kindly request a prompt review, as the app is urgently needed to be published.
