Nokia N78 how to find out which production!

Standby input, *, out if.

Bring. svn：

Such a must be fake.

The normal one is a 15-digit number, at most preceded by an iimei:

There will be nothing superfluous.

Looking at the mobile phone screen again, the imitation picture is relatively blurry, and you can see it at a glance.

Look again, if you can open the back cover and remove the battery, it is also imitation, and the real N8 battery can't be taken out without dismantling.

How to identify Nokia N8:

First, check that the three codes are consistent.

1.After entering * on the mobile phone, the serial number of the mobile phone will appear, write down the serial number (serial number, that is, IMEI code).

2.Open the back cover of the phone, remove the battery, and write down the IMEI code.

3.The IMEI code on the box of the phone.

Compare these three codes, whether they are consistent, when the mobile phone is genuine, these 3 codes should be the same.

2. Check whether it is within the warranty period.

**Mobile phone, IMEI code can be found on China Nokia online and customer service inquiry to get the warranty.

The serial number can be found on Nokia's official website.

You don't need to look up 1200 pixels, just this one.

Generally speaking, there are many ways to identify refurbished machines, which can be summarized as follows:

1. The refurbished machine generally adopts the imitation original shell, the gap is uneven, there are burrs, and the upper and lower parts of the mobile phone shell are prone to close tightly, leaving a large gap. In addition, from the aspect of feel, you can also roughly feel that the new machine is very comfortable in the hand, and the refurbished is not as good as the second-hand mobile phone with a better shell due to the use of imitation shell.

2. There is a faint sandalwood fragrance when the lid is opened for the new machine, if it is a refurbished machine, there is a rubber smell, plastic smell, or the smell of chemical agents after opening the lid or removing the battery.

3. Due to the long-term plugging and unplugging of the charger plug and data cable, the charging interface of the refurbished machine will be scratched. If you look closely, you can see that even the most professional person can hide the scratches that have been moved.

4. If there are conditions, you can carry out a charging test, many refurbished machines will lose power after a long charging time, and this situation will not occur in new and second-hand mobile phones with good motherboards.

5. Take a closer look at the SIM card chip contacts and battery contacts, these two contacts JS generally cannot be replaced. If it is a refurbished machine, then there will definitely be clear friction marks on the contacts of the SIM card chip, which will look shiny, which is caused by too much friction. If it is an unused chip for a new machine, the contact surface should be frosted.

6. Look at the fixing screws in the bright place, mainly to see if there are obvious scratches on the interface between the screws and the knife edge, and whether there are any picks on the two rubber pads under the inner screen.

7. Look at the earphones and expansion card slots for dust, whether they are worn, generally speaking, there are metal contacts inside, but it is not particularly easy to see directly from the outside.

8. Try the call quality, which is crucial no matter what kind of second-hand mobile phone you buy, and the call quality largely determines the value of the mobile phone.

The box summarizes the above points of identification methods for refurbished mobile phones, hoping to bring some help to friends who buy mobile phones, beware of buying refurbished machines.

Methods for identifying 14-day machines:

1. Whether the packaging is worn;

2. Carefully check whether there are scratches on the charging port and battery of the mobile phone, and whether the earphones and related accessories have been unpacked;

3. Enter the mobile phone interface to check whether there is a call record and whether there is a record in the address book, etc.: For example, Nokia's machine can check the total call time through *, generally speaking, this total call time cannot be cleared by non-professionals if it does not pass the grid, which can be used as a very important reference for whether it is a 14-day machine.

In general, there are many ways to identify a 14-day machine similar to a refurbished machine, so I won't repeat it here. The 14-day machine may not have a quality problem, but after all, it is something that has been used by others, and it is good to buy it as a purely second-hand mobile phone, but I am afraid that the black-hearted traders will use it as a new machine to trick people. Therefore, it is better for everyone to identify carefully.

Now** there is a new machine? It's all refurbished, take it to the after-sales service or check the serial number on Nokia's official website.
