I can't be sure about this, please give me the exact serial number!
2. Settings - General - About this machine.
The model number can be viewed. The last two CH are the national bank, ZP is the Hong Kong bank, KH is the Korean version, and LL is the American version of the machine.
The last c, is the Canadian version, X is the Australian version, B is the British version, and F is the French version.
This is often referred to as the sales region or version number).
3. It is said that the official flip machine factory is in line with the quality standards, so there will generally be no problems, if it is replaced after sale, it will not suffer any loss, and it can be used with peace of mind. But there are also sellers who will** this type of machine (no matter how it comes, anyway, the national bank can be replaced if there is a problem, ** the second mobile phone can not only be used for private refurbishment, if there is a little problem, you can also go to the after-sales service), it will generally be cheaper, such as c7g, c3k starting with the machine 3700 or so is more reasonable, I hope you can realize when you buy the machine: c7g machine is different from ordinary machine, belongs to the after-sales replacement, the quality may not be a problem, but the warranty is not one year,** It is also lower than a normal machine.
In addition, the serial number of the recently manufactured machine begins with C8 and DX, such as C8W, C8P, DX3, DX4, DX5, etc., if it is C37, C38, CCP, C39, it can basically be judged that it is last year or the first half of this year, and it should be paid special attention to the refurbished machine.
Whether it is a brand new machine, please refer to your actual purchase date and the warranty date inquired above.
This is because the warranty is a full year from the day of activation.
Satisfied, thank you! ~
