Nokia N81 phone has zzi noise?

The landlord is quite careful, and this problem has been discovered by you. This is the current sound of the mobile phone, I used a Motorola V3 before, and it is the same when the screen is on.

Filter circuit You can go to KF to test it, if other 81 also have this problem, then KF will not be replaced, just like the previous motorcycle V3, the current is loud. Generally, when the mobile phone screen is lit up, everyone just doesn't pay much attention to it.

Normal! The sound of the mobile phone horn is generally related to the magnetic field, for example, if you take two mobile phones together, dial to try it, there must be noise, and a very common one, put together with the audio, or the distance is very close, there is interference, but if, often like this or in any occasion, there is such a situation, it may be a problem with the quality of the mobile phone.

In this case, you try to mute, if it doesn't work, slap it a few times, and if it doesn't work, you can only fix it! Because mine won't have that sound.

You are talking about the sound of electric current, are you buying a licensed mobile phone? Licensed goods can go to customer service testing, if the detection is a performance failure, 7 days to return, 15 days to change, because I did not see the mobile phone dare not say that it is not normal, insist on the landlord to test, the heart is steady. When you go, call the store where you bought the mobile phone ** and ask where the designated testing customer service is, and bring the purchase invoice and warranty card.

Is it right to turn the volume up or down? Possible causes:

The first reason: external reasons, carefully check whether there is dust or something blocked in the earpiece, resulting in low sound, such as the mesh outside the earpiece is blocked by dust.

Second, the earpiece has been used for too long. I believe that your 81 is a machine for several years, which means that the earpiece has the original aging, and it needs to be replaced. The best thing is to go to the customer service to change the original, because the customer service must be a new device (but now the customer service wants ** and the phone itself **, I always feel that their asking price is really high).

You can also find a mobile phone repair office to spend money to replace it, which is not expensive. If they ask for a price, then go to ** buy an earpiece, change it yourself, the upper structure of N81 is not complicated, go to the library to search for the disassembly diagram, and you can remove the upper panel separately in order, and replace it yourself. It's all stuck, don't worry about too many small screws, I believe that the comrades who have changed the 81 shell know it very well.

There's nothing you can do, the best way is to use headphones. My original was also n81.,This problem is really tangled.,Maybe it's affected by which two game keys.。

The earpiece is broken, and after a while, I can't hear it, and it is recommended to replace it with 8 pieces, I replaced one, and I have used it for half a year, and the quality is OK.

Right"Nokia.

n81"Comments.

Playing games is refreshing enough, and the pixels are too low at 2 million pixels. Pros:

The screen is good-looking. 180 degree viewable inches.

16 million colors.

Good styling. Especially the blue ones.

The headphone jack is the same jack that you usually use on a computer. Cons:

It is easy to peel off the paint. The keys don't feel particularly good. It's a little astringent.

The game-specific keys are easy to break if they are too forced.

It's a big problem to have only 200w pixels, huh

Summary: N81 is a product with a slide shape, and uses standard millimeter headphones as the audio output port, which is more prominent in terms of sound effect. and adopt symbian

Operating system, Bluetooth support, support N-Gage gaming function, and can WCDMA HSPDA

The application of 2100MHz network makes it more cost-effective.

I'm using Nokia's N81

The downside of this phone is that the camera always has a green light.

This is a common problem.

It's not a quality issue anymore.

Also, after using it for a long time, the slide cover is a little loose.

But this. Definitely within an acceptable range.

And it's not very exaggerated.

Pros words. I still feel like it's cool to play the game.

And the sound quality is also very good.

Pros: N81 supports N-Gage gaming, headphone jack, convenient, S60 system, excellent expandability.

Disadvantages, the material of the mobile phone shell is not good, the texture is not good, the mirror design on the front is not wear-resistant, it is easy to scratch, the middle shell of the mobile phone, the plastic of the mobile phone frame is too soft, and it is easy to wear. The navigation key of the mobile phone is OK in four directions, but it is not easy to use in the 8 directions, it is too hard, the feeling of playing games is very poor, and the cover design of the mobile phone TF card slot is not good, and it is easy to be damaged. The numeric keys of the mobile phone are too flat, the key range is short, and the feel is average.

However, on the whole, N81 is still a good machine, ** is also suitable, 2300 yuan.

You can refer to it for details.

Hesitation should be dropped, just look at how much N82 is more expensive than N78 To put it bluntly, N82 is that the camera is better than N78, and everything else is about the same.

The N78 has just been launched, and the cost performance is definitely not as good as the N82

In terms of functionality, the N82 is stronger than the N78, with both the 500W pixel and the xenon flash being better than the N78's 320W pixel and LCD fill light.

N78 has just been launched** too high.
