Kyarvi,
I did not find it in the discussions even through keywords, can you tell me on which page the post, if you saw it? I will be grateful.

Update: found, downloaded the program JScreenFix. I will try it, accomplish your goal here, it helped or not (I will try all day, the program requires it). Then you can safely add instructions to the header.

And what is your region on Beeline, tell me?

I would be satisfied if the Chinese used a top microphone for the camera - the squeak would be gone.

Confirmed here:
LeEco Le 2 x527 - Discussion (Post maxryt # 53785450)

[Arkamaliev]

I tested the open camera, if you put up an external microphone, it looks like the squeak really disappears, well, or decreases

[Inko2008]

ilwe,sure what would be better? Noisy microphone dampens everything except voice. What will be on the video, gurgling from bits of other sounds and voice?

[ilwe]

Inko2008,
Let the bottom one use as noise.

Let the bottom one use as noise.

And what the hell will be in the end?

[ilwe]

Sergey1983,
Do you think there are fundamentally different models of microphones?
If not, you can take a signal from the bottom for the noise level, and from the top for sound recording
But only for the camera - it is clear that it is meaningless to talk.

You may not know the principle of noise reduction. To cut off the noise, it is necessary that both microphones hear it, and the second microphone in this situation most likely will not hear this noise.

I do not understand if I have a squeak! I recorded 3 videos in complete silence: on the main (1080, 4K) and on the front-end. For me, so there is no squeak: happy:
1080
4K
Frontalka

[killa211]

Maer80,
There are all three, but if you do not specifically listen, you can not notice.

[ilwe]

Sergey1983,
So in this case, you will not need to cut a squeak out of usb (since the top microphone does not hear it), and the rest of the noise will be heard by both microphones

Called in TP. About the squeak said the same thing that the links in the topic header in the screenshots. I think I will wait until Monday - if there are no updates - I will apply for replacement or return. I think a lot of disputes and other appeals, and better - physical returns, rather motivate the company to solve this problem.

For the quality of the connection, I was offered to solve the problem by resetting the network settings first and then the hard reset. Smart re-configure is very reluctant, I will try later.

[hdx1000]

I did not fully understand, is squeak is the problem specifically x527 or the entire line of LeEco Le 2?

[Cakol]

Half an hour ago, the courier brought the phone. And unfortunately there is a squeak. everything else seems to be oral. I would not like to change. find out whether this squeak affects life
and it is clearly audible both on the video and on the voice recorder at maximum volume

From the point of view of circuit technology, something is noisy connected to the DC / DC converter. They are used to convert one voltage to another with minimal losses. As a rule, such converters operate at frequencies of several tens of kHz, but some can also work at audio frequencies. Usually such converters are made in separate cases (a separate microcircuit) and they operate at a fixed frequency, but in mobile phones, where there is little space, they use combined microcircuits, where not one voltage is generated, but all the devices necessary for operation (there can be more than 5-7 ). Such chips are already controlled by digital buses (interfaces) and are able to change the conversion frequency and the duty cycle programmatically. For the operation of the converter, either a transformer or inductance is needed, during operation of which electromagnetic waves are generated and the more current flows through them, the more this field is. It is in them, with poor-quality manufacturing, as a rule, that very high-frequency noise occurs. In practice, such met more than once. It is not the very detail of the circuit that can make any noise, but metal elements that fall into the zone of propagation of electromagnetic waves (I haven’t seen one myself, but I have heard about this). Well, I heard the widespread opinion that a capacitor can make noise. Honestly in the latter case, I’m not sure that this is possible, with the exception of poor-quality film capacitors, but I wouldn’t exclude it completely either. So, to summarize: to identify the cause of the squeak without having an accurate understanding of the applied circuit and design solutions is difficult. If the squeak is connected to a transformer / inductance, then such devices work for years (in the same computers you can hear a similar squeak under loads with the fan disconnected), if with a capacitor, then the matter is bad, as it can simply collapse with time, if with structural elements , here I can not tell.
From the point of view of the programmer, knowing the exact frequency of the signal (squeak), it can be very simple and easy to cut with a program filter.
ZY At work, I occasionally come across DC / DC converters, but I can't say that the gurus in this matter either.

I wrote to the service centerhttps://www.irp.ru/
They said: 1. "Guarantee maintenance of LeEco products is carried out practically throughout Russia, including St. Petersburg, of course. Does St. Petersburg already have a service center. Do you want to contact a service center for the purpose of repairing a faulty device or do you have other treatment goals? "
2. "Since sales started recently, and there are still no users contacting faulty devices, we do not have any developments or technical information regarding this problem. It is possible that the information will appear in a few days when devices with these problems are in the service center, and the problem will be studied. If the rest of the device suits you, the problem is not critical, then there is no reason to immediately transfer the smartphone to the service center. Of course, if EMA brings you any inconvenience, and you want to immediately transfer the device to a service center for the diagnosis, please - we are ready to order you a courier for urgent delivery device to Moscow. "
3. "Even if you address this problem to the local SC, then 99% of your device can be sent for centralized repair to Moscow. It is now such a common practice for all such devices in almost all manufacturers."

Well, it means he does not bother me. I will not shoot silence on video, but I use the voice recorder once a year. I think that they are blowing an elephant out of a fly. If you mess with the exchange, the new phone will be exactly the same, because no one will hysterically rivet a new batch of phones. Do not those terms. You want cheap, fast and high quality. Alas, this is not always the case. I generally have a new ZUK Z1 dead after 2 months of work. 9 kilorubles to the cat: censored:
