First of all, recommend s60v3 mobile phone.
N79, straight. The basic hardware equipment is a 5-megapixel Chase-certified lens, a 2.4-inch screen and a 369MHz CPU. The price is around 1900, which has been discontinued, but it is available in some areas, so be careful to buy it.
E66. Sliding cover metal. The basic function is the same as N79, 3.2 million pixels, 9.2 system. 1700 or so. The purchase situation is the same as that of N79, so be cautious.
E52, new product, straight metal. The basic functions are 3.2 million pixels, 600MHz CPU and 2.4-inch screen. Licensed goods have wifi. Because it is a new product, it is easy to buy a new one, and the price is somewhat inflated. 1900 or so. I suggest buying it later.
N85, two-way sliding cover. The basic function is similar to N79, and the screen is changed to 2.6-inch AMOLED screen, which saves electricity and has bright colors. It's easier to buy a new mobile phone than the N79. Around 2200. Now is the best time to shoot, there are refurbished machines, but not many.
E7 1, full keyboard, straight screen, horizontal screen, the basic function is similar to N79, but it is a 3.2 megapixel camera. It belongs to the kind where the price has come down and it is easy to buy a new mobile phone. The price is around 2000. Strong and balanced hardware level.
E63, straight full keyboard. It belongs to the simplified version of E7 1, with similar appearance, less GPS than E7 1, and 200W pixels for the camera. It belongs to a relatively second-hand low-cost mobile phone, with high cost performance, and the price is around 1300. There are many refurbished machines, so buy them carefully.
E72, straight full keyboard. It belongs to the upgraded version of E7 1, a 5-megapixel 600MHz CPU, and there are many small but important improvements, so I won't list them one by one. The price is around 2300. If the functional requirements are high, you can choose this one.
5730XM, straight board, side sliding full keyboard. 2.4-inch screen, 369MHz, 3.2 million pixels. A more value-for-money one, with a general appearance. The price is around 1700. There are not many refurbished machines, nor many.
5630XM, straight board. 2.2-inch screen, 600MHz processor, 3.2 million pixels. The processor is outstanding, but the overall hardware level is not high. The price is about 1500, which is very cost-effective.
6730, straight board. 2.2-inch screen with 320W pixels. The processor is the same as 5630, with GPS, but the earphone interface is changed to 2.5mm, which is not convenient. The price is about 1500. I don't think GPS is useful for people who don't have cars. If you want to buy it, it depends on your personal needs.
6760, new product, sliding measurement full keyboard. 2.4-inch screen, 320W pixel camera. The operation may be awkward, but it is a very good one only in terms of function and price. If you are afraid of buying a refurbished machine, choose this one. The price is around 1600.
The following is the system of s60v5.
5800XM, full touch screen, 3.2-inch resistive. The processor can upgrade the CPU from 369MHz to 434MHz by upgrading V40 and canceling the version limit. 320W pixel, S60V5 system. Although there is not much software, it is enough to meet daily needs. The price is around 1800.
5530XM, full touch screen, the basic function is the same as 5800, but it is a 2.9 screen with wifi licensed. The price is around 1400.
5230, full touch screen, the basic function is similar to 5800, there is no GPS, and the camera has 200W pixels. No matter how you swim, there is no wifi, but you can use 3G. The price is around 1200. The most cost-effective fifth edition machine.
Supplement:
First, s60v3 belongs to a fairly mature system, with extremely rich software, and there is almost no software that you can't find. Moreover, the hardware requirements are low, which means that the quality of the processor has little effect on general use.
There are not many s60v5 softwares, but they are more than enough to meet daily needs. Multi-touch is not supported, and it is also a headache without QQ special edition. The requirement for the processor is higher than s60v3.
Second, even if they are all s60v3 systems, they are also divided into 9.2 FP 1 and 9.3 FP2, and their operating interfaces are different.
Third, parallel imports are not bad products. On the contrary, the hardware quality of European parallel imports is much better than that of Bank of China.
Parallel import refers to products that should be sold abroad but enter the domestic market through informal channels. Their functions are generally better than those of the Bank of China, and their prices are several hundred yuan lower. There is no warranty. Asia Pacific and Eurowater are based on different versions in different sales regions.
However, Hong Kong Bank belongs to the version with the advantages of water collection tour, which can be said to be the best version.
Fourthly, all models with XM(Xpress Music) suffix at the beginning of 5 have DAC33 music chip, which can realize hardware decoding, occupy less storage and play music for a longer time, but the music performance is not outstanding. Many N-series mobile phones perform better in music than XM series.
First of all, to verify the version of the mobile phone, you need to open the battery cover to read the code, which represents the sales area of the mobile phone and indirectly explains the function and quality of the mobile phone.
There are mainly four different versions on the market:
The European version is mainly made in Hungary and Finland, and the hardware quality is good, which is the version closest to Nokia's official design. When upgrading the version, you must modify the code with NNS, otherwise it will become all English. The price is lower.
Asia-Pacific, divided into Asia-Pacific post-engraving and Asia-Pacific non-engraving, is slightly worse than the European version, but the steps are simpler when updating the version. Lowest price.
Bank of Hong Kong. The function and quality are basically similar to those of Asia Pacific, but there is a warranty, depending on whether it is the main port or the rear port. The main port is guaranteed by the whole country, and the rear port can only be guaranteed by Hong Kong. The price is higher.
Bank of China, the function is generally similar (such as wifi), the hardware quality is similar to that of Asia Pacific, and there is a warranty. The highest price
It is recommended to search this style of code encyclopedia online before purchasing the machine, and then print it out for viewing.
The verification of refurbished machines focuses on whether the serial number in the mobile phone (enter *#06#) is consistent with the serial number in the battery slot (if you buy licensed products, it depends on whether it is consistent with the serial number on the outer packaging). There is no wear and tear on the appearance, and there is no dust in small holes or cracks (the most typical one is the hanging chain hole of mobile phone).
It's no use checking the total call time. You can make it clear to JAF.
Supplement: European version machine and Asia-Pacific engraving-free version, there are only numbers and letters on the keyboard, no strokes.
The Smartphone Players Alliance answers for you. Hope to adopt.
I typed the above words verbatim with my mobile phone, and the hardware information came from the engine oil of Saipan Forum. The system evaluation is all my own experience, and the price comes from the comprehensive evaluation of major mobile phone buying websites and supermarkets.
