There are two models of Sony Ericsson K550, one is K550i (domestic licensed product is K550c), and the other is K550im specially designed for i-mode network, which is the first time that Cyber-shot brand has been applied to i-mode network.
The first impression of K550 is fashion, with the size of 102 x 46 x 14 mm and the weight of only 85g.
Its receiver adopts the latest circular navigation shape, while its keyboard adopts thin metal strip design. This design style will be promoted in other Sony Ericsson product lines, and this year most Sony Ericsson products will adopt this simple and bright style, such as K8 18c.
K550 has a TFD screen with 260,000 colors, and the pixel value is 176 x 220 pixels. The single speaker is located above the Sony Ericsson trademark and has a silver border around the screen. The navigation keys at the bottom of the screen are also displayed in silver, which is very fashionable.
On the left side of the machine is M2 memory card slot and quick connection interface, which can be used for data transmission or charging, which is different from the previous bottom design. In fact, we also saw this design on w880, which made the smooth bottom look more beautiful.
At the top is the power switch and infrared transmitter, especially the infrared port, which makes people feel that Sony Ericsson still cares about this.
On the right side of the fuselage are the camera shutter and volume button, which can be used as digital zoom control when taking pictures.
Slide the lens cover to the bottom, and the camera function of the k550 will automatically turn on. Next to the lens are two high-power LED flashlights, which can provide strong light assistance like flashlights when taking pictures.
Open the battery slider and you will see the battery and memory card slots. The battery is Sony Ericsson BST-33 lithium polymer battery with a capacity of 950 mA. According to our test, it can last about four days, and W850 and W880 also use the same type of batteries.
The screen of K550 is made of TFD material, which can achieve the image display effect close to TFT, but the battery consumption is only equivalent to STN level. Similarly, K600, K608, K6 10 and other models have also adopted this kind of screen, and the history of this technology is as long as that of TFT.
New keyboard designs such as K550 were widely used in the new product line in 2007, and proved to be excellent in design, good in feel and convenient to hold. The short message button is fan-shaped, and the thumb can be easily manipulated when it is used, which proves that the K550 is humanized in design.
K550 has a good sound effect, and it can be heard clearly even in noisy streets, but it is not very good at grasping high notes, and sometimes there are hisses and buzzes.
The software interface of K550 is special for Sony Ericsson's non-smart phones. Two years ago, we thought it was slow, but now it is not. Similarly, the K550 also has the function of flight mode, and it can be turned on freely, but the SIM card does not work in flight mode.
Press the four-stage navigation key to enter a specific function. When you use this phone for the first time, the K550 has a simple startup menu setting, according to which you can quickly set the personalized functions of the phone. K550' s menu is a 4x3 matrix, basically all the menus are contained in it, and the speed of entering the submenu is very fast.
The fuselage has several preset themes, which can change the color and background of the menu.
Shortcuts on the keyboard are also linked with menus, such as one-click multimedia, surfing the internet, my documents and so on. Users can also include common functions, which are quite fast to use.
The phone book of K550 is quite simple for users. Users can choose whether the default phone book is SIM or body phone book, but it cannot be displayed at the same time. Our suggestion is that a single number can be stored on the SIM card, and the contact information is suggested to be stored in the phone book of the fuselage.
The whole phone book of K550 can store 1000 contact records, while the phone number can store 2500. If you want to add a contact, you must have at least five sets of information, such as mobile phone number, home phone number, work phone number, fax number and others. Subsequent information includes e-mail, address, location, postal code, ringtone and personalized pictures.
It is worth mentioning that the caller ID is different according to the caller number, which can distinguish the special situation when the same contact calls with different numbers.
K550 supports MP3, AAC, AAC+, E-AAC+, WAV, WMA, M4A, MIDI and other music files, but the playback software is nothing special, similar to Sony Ericsson's Walkman mobile phone, except that there is no MegaBass equalizer. K550 supports the background playback function, which can be played automatically in the background. In addition, the video is nothing special, but FM radio can store 20 groups of frequencies and support RDS.
It is easy to browse pictures on K550, which can be done by icons or thumbnails. There are 2x2 and 3x3 modes, and video files can also be displayed on thumbnails. If you highlight it, it will be previewed as a thumbnail.
The most interesting function of K550 is the time clue browsing function, which can search for pictures in a specific time period according to the needs of users, either monthly or weekly, with very high accuracy. At present, this function has been applied to more Sony Ericsson mobile phones.
When browsing pictures, you can change them horizontally or vertically as needed, as long as you like. K550 defaults to quick browsing and uses thumbnail mode. Moreover, for the picture K550, the local magnification can be up to 32x, but when it is actually enlarged to 16x, it is already a bit blurred.
Simply modify and edit the browsed pictures, and then transmit them to other devices via MMS, email and Bluetooth. If users want to edit them in detail, they can use PhotoDJ software. This software can help users easily adjust white balance, brightness, contrast and red eye.
As a member of the Cyber-shot family, K550 naturally makes us curious. It is equipped with a 2-megapixel lens, with auto-focus function and double LED auxiliary fill light. It has the functions of night, selfie mode, panorama, photo frame, sports and other modes, as well as exposure compensation and monochrome.
At present, the autofocus function of K550 is not perfect, which may be related to the fact that we are evaluating a beta version. I believe this will not happen after the official version goes on the market. In addition, when you are too close to the object, you can use macro mode to shoot.
As two data transmission functions, GPRS and EDGE can be supported by K550, and also support USB, Bluetooth, infrared and other modes. Among them, Bluetooth supports 2.0 specification, and pc can be remotely controlled through Bluetooth devices, such as playing multimedia, opening and closing programs, and so on. In a deeper sense, it is more appropriate to call it the Bluetooth control center.
In addition, K550 can also synchronize with OUTLOOK calendar, contacts and other items through synchronization software, so that users do not need to manage on a small mobile phone, and most functions can be realized with the help of a computer. Under the setting options, K550 has many common functions, such as calendar, synchronization, alarm clock, software applications and so on. Calendar can be browsed by month and week, and T9 input method makes K550 text input more convenient. There is no length limit for recording options, just according to the size of your memory card.
K550 has two built-in games, which should have never appeared on other machines of Sony Ericsson, so it is full of freshness for us. The first game is called fruit pie, which is similar to Tetris. You must first collect the same kind of fruit, then remove the surrounding railings and finally go through all the customs. The protagonist of this second game is actually a "Bug", but the tool is changed to golf, so the name is Bug Golf, and the purpose is much simpler. If you hit the ball into the hole, then the person who hits the ball the least times is of course the winner.
