N78 Disadvantages: 1. Basically, the panels near the Nokia N78 multimedia keys are inclined, which is far from the workmanship on the left. It seems that it has been used by others 1 year. The corresponding back cover is also loose. There seems to be something wrong with the design of this work. People with big hands are not recommended to buy N78. For the solution to the loosening of the back cover of Nokia N78, everyone uses the method of padding paper or adhesive tape to solve it. As it turns out, this method is suitable for other machines, but not for Nokia N78.

N78 Disadvantage 2. The interface switching of Nokia N78 and the access time of common functions such as contacts, short messages and self-contained browsers are not as fast as before. People who may say they are fast just used 73. Actually, it's a little slower than N82, compared with 5700. 6 120 is much slower. However, this slow gap is only 0. 1-0.3 seconds. When using N78, there is no delay. I just said that the normal function of N78 is not faster than that of N82. The legendary system optimization makes the system fast and should only be aimed at 73. In addition, if the theme dynamic effect is turned off, N78 runs faster than N82.

N78 Disadvantage 3. Taking pictures in the sun, the screen of Nokia N78 is the same as that of N82, and it is still basically unclear.

N78 Disadvantage 4. The internal amplification of Nokia N78 is much higher than that of 82, and the stress is not as high as that of N82 and N95, so it is full. N78 external amplifier is still not good. Feeling worse than a single speaker 6500C?

N78 Disadvantage 5. The smog theme of Nokia N78, I don't want to use it once. At the expense of speed ...

N78 Disadvantage 6. Due to the lack of memory, many other things will get stuck when listening to songs, and the songs will be seriously rough when they get stuck. For example, when listening to songs, you can visit this forum with your own browser. (through the edge). When the program is opened for a long time, there will be a very long delay in browsing photos and taking photos. Will it be useful to use 20 1MHZ? Dopod effect of CPU. It may be unbearable for N82 users. Correction: You can choose to turn off the theme dynamic effect of N78, and the program runs very fast.

N78 Disadvantage 7. My Nokia N78 right-click button is pressed in the same way as my mobile phone friend, but sometimes it doesn't respond, sometimes it's like hitting the hang-up button and exiting the standby interface directly. It is easy to misoperation. ?

N78 Disadvantage 8. The sound of Nokia N78 camera can't be turned off. Even if you choose to turn off the flash, it will still flash a little to warn others. Sneaking with N78? It's hopeless to take pictures.

N78 Disadvantage 9. For experienced S60 players, how does it feel to see the first line "Show all running programs" every time you press the left option key of Nokia N78? In the past, many programs were closed by "left option key+up key +OK key" and then exited. At this time, if you do this conveniently, all the running programs will be displayed. (Now you need to press the up button twice) Personally, I feel very uncomfortable. It can be seen that N78 is tailor-made for S60 junior players.

N78 defect 10. If the Nokia N78 doesn't have a font library, many programs are already available. If a font library is installed, it will be a torture to the small memory of N78.

N78 defect 1 1. If Nokia N78 doesn't install tripartite software when sending SMS, it still only displays "a new message" and can't display the sender like S40.

The disadvantage of N78 is 12. When Nokia N78 finds someone's name in the address book and directly presses the dial key to make a call, the response is not as fast as that of S40. Judging from 1 1 2, the new version still has some reservations in the process of absorbing the advantages of S40.

My N78 has many problems, such as the back cover, flash, serial key, external display, the sender can't display it and so on. Watching movies does not affect personal use. Plus there is light leakage on the front. ?

How about another 5530 and 5800? Because there are striking similarities between the two models? Compare them together. All right.

Shape contrast

Nokia 5530XM and 5800XM are completely different in appearance and style. First, let's look at the shapes of the two machines. Nokia 5800XM is larger than 5530XM. Let's look at the data gap between the two machines. The length and width of the Nokia 5530XM fuselage are 104mm and 49mm respectively, while the 5800XM is 1 1mm and 5 1.7mm, and the 5530XM is shorter.

In addition, the width is also of great concern to everyone. The fuselage thickness of 5800XM is 15.5mm, which is relatively thick, while the thickness of 5530XM is only13 mm. Although it doesn't look much different, it feels obvious after getting started. 5530XM is easier to control, and 5800XM is a little hand-held.

Many netizens think the Nokia 5800XM looks weird, and I feel the same way. The 5800XM is a bit like an "inverted trapezoid" design, while the 5530XM is a more traditional shape. The front and back dimensions are relatively equal, so at first glance, 5530XM should be more "popular". On the other hand, the protruding frame on the front of Nokia 5800XM is easy to accumulate dust and stains. This design has been improved on the 5530XM, and the overall feel of the Nokia 5530XM is more comfortable.

I believe that the texture of the fuselage is also very concerned by netizens. First of all, neither machine is made of large-area metal, and the front frame of Nokia 5530XM is also made of engineering plastic. Since the basic materials are almost the same, it is natural to compare the paint layer. Nokia 5530XM uses matte paint layer, which has good fingerprint resistance, while Nokia 5800XM uses matte material on the back, plus arc texture. From the back, the Nokia 5800XM is more upscale.

Detail contrast

As can be seen from this position, there are great differences between the two machines. Nokia 5530XM is equipped with a receiver, a speaker and multimedia keys. In addition to the receiver and multimedia keys, the Nokia 5800XM is also equipped with a 3G camera and the most practical optical sensor. These two pieces of hardware did not appear in 5530XM, and the lack of light sensor is really a pity for 530XM.

As for buttons, Nokia 5530XM follows the trend and adopts inductive buttons, while 5800XM is a traditional physical button. Because there are only three buttons, 5530XM will not be frequently pressed by mistake, and its practicability has not been significantly reduced.

The two card slots of the Nokia 5530XM fuselage are located on the left side of the fuselage like the 5800XM, but the difference is that the 5800XM microSD card slot and SIM card slot have independent dust covers, while the 5530XM has a 1 cover, so this cover is very exaggerated. As can be seen from this detail, Nokia 5800XM has a higher positioning.

Since the SIM card is inserted in the side of the fuselage, how to take it out? The design of 5530XM is the same as that of 5800XM, except that the battery needs to be removed, and then the SIM card needs to be pulled out with a stylus. The original intention of this design should be to prevent the SIM from being burnt out when it is turned on, but the trouble brought to the user can not be ignored.

Nokia 5800XM puts the power button, charging interface, 3.5mm earphone interface and data cable interface on the top of the fuselage, while the bottom is empty. In contrast, the 5530XM only has the power button on the top, and all other interfaces are "thrown" to the bottom. In practical use, I think 5800XM is more convenient.

Screen contrast

Both machines use the platform of S60 5th edition, and the system supports the same resolution of 360*640. There is no difference between them. In addition, the material of16 million color TFT is the same. From the data point of view, the biggest difference between the two machines is that the screen size of the 5530XM is only 2.9 inches, which is a little smaller than the 3.2 inches of the 5800XM.

Although the size of 5800XM is large, the display effect is not excellent. It should be said that the screen performance of 5800XM is only near the passing line. Many netizens complained that the color of this screen is cold and You Lan. We specially sent a test chart to compare the actual effects of the two machines. Results The performance of 5530XM was obviously improved, the phenomenon of cold screen was solved, and the color performance was slightly better than that of 5800XM.

In addition to the improvement of color performance, the viewing angle of 5530XM screen is much better than that of 5800XM. The performance of 5800XM is not satisfactory whether it is left or right or up or down. Although the screen size of 5530XM is reduced, the overall display effect is satisfactory. And in fact, the screen gap between the two machines is larger than that shown in the picture.

Backup interface comparison

Although the same S60 fifth edition platform is adopted, there are still some differences between different models. Among several S60 fifth edition models currently launched by Nokia, the main difference lies in the standby interface, including Nokia 5530XM, which is slightly improved compared with the standby interface of Big Brother 5800XM, making it easier to use.

In the fifth edition of S60 platform, there are several standby modes for us to choose from, such as general mode, shortcut mode and booth mode. Compared with 5800XM, 5530XM improves the card seat mode, opens the interface, and adds shortcuts and email functions. In addition, the left and right soft keys are added at the bottom of the interface, which is closer to non-smart phones, which makes it feel much more convenient and integrates various functions.

In addition, in terms of input method, Nokia 5530XM has also made a simple modification, so that the screen can realize virtual full keyboard when it is displayed horizontally, while Nokia 5800XM can use full keyboard when it is displayed horizontally and vertically, but the narrow space will often lead to the wrong pressing of full keyboard when it is displayed vertically. 5530 canceled the straight mini full keyboard, but this cancellation has little effect.

System hardware comparison

I believe everyone is very concerned about the core hardware of the two machines. Nokia 5530XM is defined as a "shrinking" machine by many netizens. So does the core part of the hardware really shrink compared with 5800XM? We installed a professional JBenchmark? ACE tests the CPU running frequency of 5530XM and 5800XM. According to the test results, the running frequency of Nokia 5530XM and 5800XM is 385MHz, and the CPU is based on ARM9 architecture. It is believed that the two machines use the same CPU.

Then we installed the memory management software TaskMan. In the new boot state, the idle running memory of Nokia 5800XM is 60MB, while that of Nokia 5530XM is 55MB. Except that the running memory of Nokia 5800XM is slightly larger, there is no difference in the overall response of the two computers.

JAVA performance comparison

Then we installed Jabenchmark series software to test the JAVA running ability of two computers. From the test results, Jbenchmark Nokia 5530XM is slightly higher, while JBenchmark 2 is slightly higher, and the difference between the two computers is not big, which can be basically ignored.

Standby time comparison

Nokia 5530XM has a smaller body and uses less battery capacity. The capacity of BL-4U battery (left) is 1000 mA, and Nokia 5800XM is BL-5J battery, 1320 mA, which has certain advantages in terms of capacity. As far as practical use is concerned, under the same use conditions, Nokia 5530XM needs to be charged once every two days, while Nokia 5800XM can last a little more than two days, and the standby time is not far apart. 5800 has a little advantage.

Support WAPI

Although the positioning of 5530XM is not high-end, it is Nokia's first mobile phone supporting WAPI. WAPI is the first secure access technology standard in China with independent innovation and intellectual property rights in the field of computer broadband wireless network communication. Technically, WAPI has certain advantages in security, so WAPI is the transmission protocol standard popularized in China at present. In other words, Nokia 5530XM is Nokia's first mobile phone with WiFi in Chinese mainland market, while the domestic version of Nokia 5800XM has cancelled WiFi, so it has an inherent advantage in network application.

Comparison of shooting functions

When Nokia 5530XM appeared, it was called a "shrink" machine. One of the most important reasons is that the 3.2 megapixel autofocus camera has not changed compared with the 5800XM, but it has not been certified by Carl Zeiss, so many netizens can't help but question the shooting ability of the 5530XM. In addition to the shrinkage of the lens, the 5530XM cancelled the 5800XM dual led flash and replaced it with a single LED fill light, which is another shrinkage in hardware.

Although the hardware has shrunk, we compare the shooting interface and shooting function of Nokia 5800XM and 5530XM, but we are delighted to find that there is no difference between them. Enter the interface, the left is the view box, and the right is the function button. The camera icon on the right, if clicked, will automatically complete the action of focusing and shooting without pressing the shutter button. In terms of shooting function, the two cameras can adjust the scene mode, grid, timing, tone, white balance, exposure, sensitivity, contrast and sharpness. Although Carl Zeiss certification has been cancelled in hardware, the shooting function of Nokia 5530XM has not shrunk.

We comprehensively compared the two platforms of Nokia S60 5th Edition. Although Nokia 5530XM omits 3G module, Carl Zeiss authentication, GPS navigation function and other hardware configurations compared with 5800XM, it still has its own bright spots, such as a smaller body, which is much more comfortable to put in the trouser pocket. In addition, the screen effect of Nokia 5530XM is much better than that of 5800XM, which are advantages that cannot be ignored. For users who buy regular licensed products, 5530XM supports the national WAPI standard and has advantages in network application. As long as the market positioning is reasonable, Nokia 5530XM will inevitably become an arcade with high playability. ?

So I still support the landlord to buy 5530XM ~5800. I have friends who bought it. To tell the truth, no matter how boasted on the internet before. It doesn't feel good to actually get it in your hand. Are the pixels in the room? A dark place? A dark place? And lighting are not very good places? When taking pictures? The screen effect is super bad? Not clear? Debugging many settings is useless? Finished flashing? Is the 5800 display screen seriously exposed? Taibai? !

Like a man upstairs mentioned that all the 5800 machines were stopped, and all the machines were stopped? After-sales service is inevitably worrying.

5530XM, as soon as it appeared, laid an advantage at a price close to that of civilians, instead of doing gimmicks like other models, and its configuration performance is ok, its CPU is strong and its cost performance is extremely high! It is also suitable for girls. Since it was only listed in August, I hope it can bring us more surprises ~ Have a good shopping in LZ (* _ _ *). ...
