The first thing you need to know is what accessories are available for the N73. The most important accessories for the N73 are the battery, charger, and headphones, although the original HS-23 headphones are generally effective. The difference between the original battery and the high-fashion battery must be known. In addition to checking from the serial number, the color of the reed, the authenticity of the label can be seen, as well as, the two dots at the bottom of the real battery are two small holes, while the high imitation is almost flat. The original battery is important, you can easily standby for three days, and there is no delay in listening to songs and watching movies. Then there is the charger. The original is AC-4 charger, 100-240V, 890MA output current per hour, don't let js fool you. And the HS23 headphones. About the headphones will explain in a bit. There is also a USB cable, charger large port to small port adapter cable, 128MB-miniSD card, CD-ROM. It is said that the Hong Kong version also has a small triangular stand, and a Bluetooth mouse.
With all the accessories, it was time to pick the phone.
First make sure it's a brand new machine, not refurbished. Enter the *#92702689# command to see the phone's talk time. Then enter *#06# to see if the cell phone serial number matches what is written on the machine under the battery. As for the serial number written on the box, leave it alone, the watercraft is definitely not from the original box.
At the same time, feel the N73's keyboard. the N73's keyboard feels great when you press it, and there's almost no sound, so texting is a pleasure. Also the back cover of a new phone is usually not loose. But after a long time they are a little loose, don't be afraid, it's within acceptable limits.
Then debug the machine in the following four parts.
1, first of all the first to see the screen. This is the most important, please be sure to pay attention. Take the software Qreader1.87 with you. This is the software to see the e-book. After installation, enter the program, set the background were white, black and other colors, carefully observe whether there are bright spots, dark spots, the screen is off-color. If the environment is relatively bright with clothes wrapped up to see. At the same time the screen's five levels of brightness to adjust the brightness should have a clear difference, the highest brightness is very bright, and can even feel more harsh. In short, we must not let go of the screen, it is recommended to look at more than 10 minutes. Otherwise ironically regret.
This part of the problem is mostly off-color, bad dots, very few have a broken screen (a little scary). Although the protective plastic of the 73 screen is softer than the 3230, but it is absolutely acceptable range, some people say that putting an egg on it can see the watermark on the screen, absolutely irresponsible to say.
, the lens part. The mechanical shutter of the phone was a bit stiff at first, but I feel that mine now works well enough, probably because I'm used to it. During the shooting process, pay attention to observe whether there is no off-color phenomenon. Also note if the flash is working properly. Take a look at the front camera by the way. Just open the camera in the system without opening the back cover. The front camera is sensitive to light and performs well in daylight, with serious noise in the house.
The problem that occurs with this part is that the resulting photos are occasionally dark or even unreadable. Occasionally the flash does not flash. To clarify, because the N73 has an autofocus function, the flash is always on when it is autofocusing. When shooting, the flash will decide whether to light up or not according to the light of the surrounding environment. Of course, it can also be forced off or on.
3, the system part. First enter *#0000#, my phone shows v2.0628.0.0.1, 10-07-2006, RM-133, Nokia N73(11). This is one of the more stable versions out there, most of the Asia Pacific versions are this one. It's also a good idea to bring a few programs to install. For example, smartmovie 3.25, process management, office suite, etc. to see if it works. Also use process management to check the memory usage. When you turn on the computer, the free memory is around 19-21MB, after running the program for a while, it will drop to around 10 at the lowest. If you get reboots and white screens when the memory is high, be careful.
4. Multimedia section.
First of all, use the normal signal-to-noise ratio of the mp3 audition speakers. Because it is a new phone, the effect will be better in the future. N73 speakers are excellent, not only the volume of oddly large, and the control of the broken sound is quite good, the volume of the largest time can not feel the feeling of broken sound, there is also because of the quality of the mp3 is not good, and can be heard. The number of speaker holes at the top and bottom are not the same, but the volume is almost the same, almost indistinguishable.N73 speakers to high-frequency and mid-audio-based, the human voice, especially girls' reproduction is particularly excellent, but for the bass is still a soft spot, may be for the sake of power saving considerations. If the bass is really good, it's probably going to be more power hungry than vibrating.
Then there's the internal amplifier. The original HS23 headphone effect really makes me sweat, not only the bass is not good, the volume is on the low side, and the sound is almost gone when watching 3GP movies, which is a common phenomenon. The solution is to use other headphones instead. ad49 adapter cable is good. I used kosspp, worth about 400$. Listening to the N73's internal amplifier feel the bass thick, loud, surging, and listen to the CD is almost the same as the 3GP problem is also solved. So you don't have to worry about the N73's internal amplifier, even a few dozen dollars of MX500 will be very good. Some people use the Rambler H260 which is also good and is in-ear.
Since this is the multimedia section, I'll mention the pictures, the wallpaper on the N73 is a 240x240 square picture, and if you want a full-screen wallpaper, you'll have to make a theme. In fact, the theme is very simple, you can slowly learn, you can also go to my theme site to do it yourself. If you put the wallpaper in minisd, when you remove the card, the wallpaper will not be there, you need to reset. So you can copy the frequently used wallpapers directly to the cell phone storage.
Finally, the video part that everyone cares about.
The N73 supports mp4, but the requirements are quite harsh, the audio part must be aac, if it is mp3 it can't be played. High quality 3gp is a great substitute for mp4. The software I use is imtoo 3gp. The specific parameters are: encoding xvid, 320X240, bit rate 256-512 can be, the number of祯15, the audio part of the mpegaac, bit rate 128Kbit/s, sampling rate 44khz, channel 2. 3gp so that the compression is comparable to the mp4.
Of course, there are old smartmovie
Of course there's the old smartmovie, which supports xvid and mp4 encoded avi. but it's not cracked yet. Pity.
That's basically it, if all of the above passes, your N73 should be fine. A few final points.
The N73 is not compatible with watermarked minisd cards, so try to buy a genuine one. the N73 supports 2G minisd. i use a 1G kingmax card, and so far i haven't had a single problem with it, and everything works fine.
Sure you want to buy? Remember to make a phone call to hear it, then have a different friend call you a few more times. In addition to looking at the handset and microphone, if you turn on "Say Caller's Name" in profile mode, you will occasionally get a reboot as soon as you pick up the phone. I don't have this problem with my N73, and I can say the name and answer the phone just fine.
The easiest way to tell if you've purchased a 3 is a licensed product! The method is: in the standby state press *#06# pop up a cell phone serial number and then fill in the serial number to: / A4630634 this site to check whether the warranty in the warranty is the line of goods, otherwise it is a water goods!
