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. Post has been editedblackerandrew - 05.10.16, 08:46 |

Old resident [offline] Group: Curators Messages 754 Check in: 26.12.09 LeEco Le 2 x527 Reputation: 34 | 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 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.

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. |

User [online] Group: Friendssavagemessiahzine.com Messages 74 Check in: 04.06.15 Reputation: 1 | 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 Post has been editedCakol - 05.10.16, 12:46 |

Visitor [offline] Group: Active users Messages 16 Check in: 14.05.10 Reputation: 2 | 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. Post has been editedkyrok - 05.10.16, 12:57 |

Novice [offline] Group: Active users Messages 30 Check in: 16.05.11 LeEco Le 2 x620 Reputation: 0 | 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." Post has been editedDholl - 05.10.16, 13:28 |

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: |
