Many friends are asking me again, "Why is my iPhone not as useful as others? Is the quality and experience the same between different versions of iPhone ?" After reading this article, I will tell you the answer.
In fact, my friend said that his iPhone was not easy to use and had obvious lag. My first reaction was that I might have bought a "code changer" or "capacity expansion machine". We saw through the detective GSX that there was indeed something wrong with this phone. This is a "modified" phone with problems.
In fact, when many friends buy mobile phones, they only look at the data displayed by the machine itself, or look at third-party tools such as Aisi and Hourglass. However, as long as the "Mane" is in place, these data can be modified, and some merchants will even fool "novice" consumers by using inferior products as good ones. Next, I will share with you the experience summarized over 10 years to help friends avoid trampling on tricks.
First of all, we need to know where to distinguish the version of the machine. Find "General" in "Settings", and then in the "About Native" interface we find "Serial Number".
starts with the first letter of "serial number", "F" starts with Foxconn in Zhengzhou, "C" starts with Foxconn in Shenzhen, "D" starts with Chengdu Foxconn , and "G0" starts with Heshuo in Shanghai.
is not enough to know where it was produced. We also need to know how to judge the machine type. Next, look at the "model number". The first letter is "M" to indicate the retail machine, "N" to indicate the official replacement, "F" to indicate the to indicate the official machine , and "3" to indicate the demonstration machine. The letters before and after the last slash ("/") of the "serial number" also have special meanings. The letter on the left represents the place of sale of the mobile phone, "CH" means the national bank, "ZP" means the Hong Kong version, "TA" means the Taiwan version, "LL" means the American version, and "J" means the Japanese version. Among the many models, the number one ranks first is Shenzhen Foxconn.
However, this information cannot be fully believed, because there will be "code change" and other situations, so in the end, you need to look at the gsx data of the machine inspection detective, so that you can determine whether the machine has a problematic model such as "code changer", "capacity expansion machine", "official changer" or "resource machine". Of course, you don't have to worry about it, just look at the original gsx data.
So which version is your phone? Welcome to leave a message in the comment area.
