Dopod 31, evaluate it.

objectively speaking, no matter what kind of operating system the smartphone is, it is difficult to price a new product below 3, yuan when it comes to the market. However, a smart phone model 31 (S31 from HTC Hongda) listed by dopod in Chinese mainland has surprised people. It not only has a fashionable body shape that uses a lot of exaggerated arcs, but also adopts the latest version of Windows Mobile 5. operating system of Microsoft, equipped with a 1.3-megapixel camera and OMAP85 central processing unit with effective working frequency of 2MHz from TI. On the one hand, the hardware has not shrunk, and at the same time, the functions are as rich as possible, which explains the word "cost performance" for us ...

Screen/buttons/sides

Of course, for the sake of cost, Dopod 31 is only equipped with a 65536-color 176×22 resolution TFT screen with a visual area of 2. inches, instead of operating from Windows Mobile 5.. But don't worry that the decline of screen resolution will affect the final use, because the products such as 565, 575 and 585 also used this resolution.

Let's take a look at Dopod 31' s exaggerated keyboard. The main reason why they are exaggerated is that none of the 18 buttons are neat rectangles, the corners are radian-treated, or the two sides are diagonal ladders. However, because the contact area of each key is very wide, and the key surface has also been frosted, the usability of Dopod 31 is still very high.

even on its left and right sides, Dopod 31 has not missed this opportunity to use abstract arcs extensively. There is a black decorative edge between the upper and lower dark gray parts of the machine. One end of it is tilted to the top of the fuselage, while the other end is slightly drooping to the bottom, which looks extremely elegant. The side elements of Dopod 31 are all concentrated on this arc, with the volume control button on the left and the power supply and camera button on the right.

two ends/camera/battery

Dongdong designed at the top of Dopod 31 fuselage is not a button, but actually a mechanism to remove the back cover, while the standard mini USB interface and lanyard bolt are concentrated at the bottom of the machine. Turn it over and look at the back of 31. Only a 1.3-megapixel camera is waiting here alone. Because Dopod 31 is a "cost-effective" mobile phone, it is reasonable that there is no flash and selfie mirror, and it is not 2 million pixels.

When the back cover is removed, we can see the Dopod 31 speaker next to the camera head, which is why there is a gap next to the camera head on the mold of the back cover, and it is dustproof by a layer of grid medium. The third-party mini SD memory card slot of this machine is still arranged under the battery, which unfortunately means that we can't perform hot plug operation on Dopod 31 without turning it off.

looking back at the ST26A lithium-ion battery equipped with dopod 31, its capacity is still 3.7v115mah. However, since the manufacturer has become Samsung, the production area has been changed to our neighbor Korea accordingly. And its performance is fairly good. If you talk for about 1 minutes a day, send and receive 2 text messages, take 15 photos and listen to music for 3 minutes, you can basically stick to the use time of three days and two nights.

hardware uncovering

when we enter "Start-Settings-Other-About", the first thing we can see is the operating system adopted by Dopod 31-Microsoft Windows Mobile 5., and the platform is Smartphone. Although this machine doesn't adopt the TFT screen with QVGA(24×32) resolution like its predecessors such as 577W, 586W and 71, it doesn't prevent Dopod 31 from adopting the latest version of WM 5. operating system.

keep pressing the direction key, and we can see the following contents: 18.88+43.63MB memory combination. Among these spaces, the actual user's storable memory space is 12.23MB, while the program's callable running memory space is 25.64MB. It can be said that this hardware configuration can definitely meet the various application requirements of running Windows Mobile 5. operating system Smartphone platform smoothly.

We can also see that Dopod 31 uses TI's OMAP85 CPU, and its working frequency reaches 21MHz. It adopts Low-voltage technology, the manufacturing process is only .13 micron, and the working voltage can be dynamically adjusted between 1.1-1.5V.. The whole processor * * * has 289 contacts, and the area is only 12×12 square millimeters. In addition, OMAP85 adopts m-BGA package.

OMAP85 is a part of TCS35, the EDGE chipset of TI company, which works at 2MHz and has 16KB first-class cache. The unique JAVA hardware acceleration can greatly improve the processing performance of smart phones in streaming media and applications. The OMAP85 can not only make the mobile phone work in GSM 9, PCS 19 and DCS 18MHz tri-band network environment, but also use GPRS Class 1 for high-speed wireless Internet access, and can also transmit data wirelessly through EDGE, which is known as the "second 75 G network". This chip can also support EFR, FR, HR and AMR voice technologies, which can ensure clear call quality to the maximum extent.

Music function

Although it is not a mobile phone with music as its selling point, thanks to its kinship with Microsoft, Dopod 31' s ability in this respect is still quite expected, so we still evaluated it. Firstly, several files with different compression ratios in common music formats are selected to test the compatibility of the machine. Happily, this machine can recognize and play MP3 music files with all the above six common compression ratios, including 56kbps, 128kbps, 16kbps, 192kbps, 256kbps and 32kbps.

dopod 31 comes standard with a pair of silver-white hands-free headphones. No matter the cable, wire control, or small clips used for fixing, dark gray is used which is very harmonious with the fuselage. The wire control part consists of a hands-free key for answering/hanging up the phone and a volume control slider. However, because there are no music playing keys at the bottom of the screen that are easy to operate like 585 and 586, this design gives people a somewhat simple feeling.

through the audition, I personally feel that the sound quality of this earphone delivered by Dopod 31 is still very good. Especially the middle and high notes are very commendable, but the bass dive is slightly insufficient. However, this phenomenon can be improved with the increase of music compression ratio, and we think it is not an exaggeration to call it a headset comparable to the Sennheiser MX3. However, because its interface adopts the mini USB standard, it also brings inconvenience to those music enthusiasts to replace their favorite third-party headphones with better effect.

photo function

dopod 31 adopts a brand-new photo interface, which can not only take a full-screen view, but also reflect some related settings around the screen. Click the left function key to enter the detailed settings page. By constantly pressing the left and right direction keys, you can take a selfie delay of 2/1 seconds, the storage location of main memory /mini SD card, automatic/daylight/night/tungsten lamp/fluorescent light white balance, black and white/retro/cool color/negative effect, 128× 124/64× 48/32× 24/.

main menu/phone book/short message

As one of the important changes of Windows Mobile 5. operating system and SmartPhone platform, Dopod 31 completely abandoned the original list main menu style similar to the start menu on the computer, and replaced it with a 3×3 nine-square grid style, which looks very kind. We can navigate among them by the direction keys, or press the 1-9 number keys to directly start the corresponding functions, which is really convenient.

31 adopts the Sp platform standard business card phone book, which can record information from family name, first name, business phone, mobile phone, home phone, e-mail, pager, car phone, business fax, home fax, assistant phone, wireless phone, web page to company, department, position, office address, home address, other addresses, notes, birthdays and anniversaries.

dopod 31 has several input methods, such as T9 pinyin, T9 strokes, English and numbers, which support infinite association function. However, when switching between them, there is no need to press it for a long time, just click the * key, which is really more convenient than before. However, the WM Smartphone on the Smartphone platform has been dissatisfied with Xiaobian's long press of the number keys to select words, which will affect the input speed of the thumb family to some extent.

the file management tool of manager/reader /Task Manger

Dopod 31 (is called "File Explorer". In addition to the basic functions of copying, cutting, pasting, deleting and renaming, you can also view by icon/list, sort by name, date, size and type, or jump directly to my device, memory card and my document, which is convenient and fast, and there is no need to install third-party tools.

since 71, dopod's Smartphone platform smartphones have been compatible with MS Office electronic documents commonly used on our computers. This time, dopod also built a built-in PDF browser for the 31, plus the traditional Document, Presentation and Worksheet, which not only overfulfilled the task, but also eliminated the trouble of users' own installation, and the stability was even better.

The "Task Manger" hidden in the last layer of the main menu is actually what we usually call "Program/Process Manager". Its function is nothing special, that is, it can view and close those applications that don't need to be used any more, but still run in the background. On the one hand, it saves system resources, on the other hand, it also saves battery power. Whether it is a veteran player or a novice, it is very helpful.

Connection function

There is also an icon named "Communication Management" in the directory at the last layer of the main menu. Here we can quickly activate the flight mode, Bluetooth module, vibration mode and synchronization function of Dopod 31, which is simple and convenient. At the end of this evaluation, we tested the Bluetooth transmission speed of 31 according to the convention. When receiving a 2.5MB RAR file wirelessly from Xiaobian's own notebook, Dopod 31*** took 1 minute and 12 seconds, which is relatively ideal.

evaluation summary

dopod 31 will also distribute 115mAh lithium-ion battery, travel charger, stereo headset, mini USB data cable, 256MB mini SD memory card and a CD with various application software and game resources in the standard licensed sales package. Therefore, although Dopod 31 is not equipped with TFT screen with QVGA resolution, higher pixel camera and Wi-Fi wireless Internet access function, the affordable price and many features introduced at the beginning of this article make it a rare and cost-effective smartphone.
