Remove the machine battery, see two tabs in the fuselage behind the white label serial number and serial number of that case, another tag is a network license.
Whether and in front of the digital consistent; look at the machine on the box IMEI, comparing the three, look to whether agree.
If the motherboard serial number and chassis serial number is consistent, then the machine is likely after repair or assembly of parts, do not buy.
If the three strings are the same, coupled with a network license it, basically can prove that this machine is genuine, but not one hundred percent sure, because now JS what can be fake,
The motherboard serial number can use computer and software brush writing, fake IMEI label and network access license is a few pieces of money can buy, caution should also be according to the following method to verify.
* see the machine packaging and instructions
Printing regular new machine packaging and manual exquisite, multi coated paper printing, font and image is very clear, there is a sense of hierarchy, and the packing box of fake but for many simple single-sided paper copy,
Fonts and images are very rough, printing illegible, many non formal channels of modified instructions even copy. There are some refurbished machine is used although box and instructions of the original authentic,
But after all, the machine is old, the packing box shall wear, the specification must also exist used traces, the time of purchase to pay attention, can be found in.
* see the network access license

JS sold before using a like cleaner fog agent spraying, the surface of old shell immediately appear a like new machines like frosted effect, if not carefully check, will be JS away,
But in not the long time, the chassis of the paint will fall, when buying, must carefully observe the shell, because the JS process is again good, also do not have the original factory advanced equipment,
If you look closely at the words to be able to see a bit of small particles, dust, paint did not work because in the vacuum room cause.
* if it is combined with the office renovates machine can also check the flip, because some of the time, even if JS take the machine surface treatment is good, these places also inevitably leave some traces of dust.
In addition to check whether the new body screw, there is no screwdriver screwing over traces. What should be noted is that many new mobile phones have a distinct smell of sandalwood,
