Skype today is a popular communication tool; it can be used to talk with friends for a long time or conduct business negotiations with partners. But sometimes some problems arise in the program. For example, I recently encountered the fact that during a conversation on Skype, an echo was heard, which interfered with a normal conversation. If you sometimes hear an echo on Skype, you are probably very interested in how to remove it. Before fixing this problem, it is important to find out on whose side the echo is occurring - on the other side or on your side.
During a conversation, when you hear an echo, ask the other person to reduce the volume on the speakers, if he uses them. Then you can ask to lower the volume level in the computer settings. Finally, restart the program and make another call. If the problems continue after this, then most likely the problem is with your computer and its settings. Therefore, it is you who needs to determine how to improve Skype so that echoes are not heard during a conversation.
Skype itself has a built-in echo canceller that can detect and reduce echoes. And if during a conversation you hear your own voice, then the problem is coming from the responding side. When the other person hears his own voice, the echo is caused by your computer.
After identifying the source and determining why there is an echo in Skype, the problem can be resolved by performing the following steps:
Important! You need to download Skype from the official website of the developer.
Select the volume control, this or a similar window will open (depending on the OS), in which you can make settings:
If you are using a stereo mixer (in addition to other audio input devices), it must be disabled. To do this, go to Options/Properties and check the box at the bottom right (under Stereo mixer).
So, by working on the volume settings on the computer itself, turning down the volume on the speakers, or putting on headphones, you can quickly deal with echo in Skype. Let your conversations be clear and pleasant!
While espionage passions flare up in the United States and follow, ordinary citizens of both countries are having fun with “harmless wiretapping” of other people's cell phones.
It must be said right away that it is impossible to listen to a cell phone by intercepting its signal using some kind of box with an antenna. The data transmission channel is well encrypted, so “wiretapping” at this level can only be carried out by telecom operators themselves at the request of certain intelligence services. However, you can keep an eye on your beloved wife in less high-tech ways.
There are many programs readily available on the Internet that can secretly work on the victim’s phone and save or transmit to the side recordings of telephone conversations, SMS messages, geographic coordinates, and even pictures from the built-in camera. Some programs can work like a full-fledged “bug”: you call the device and, unnoticed by the owner, hear everything that is happening around. This is quite convenient when you need to eavesdrop on a secret meeting or an equally secret date.
Users of phones based on the Symbian and Windows Mobile operating systems are at risk. There are spy programs for the iPhone, but you won’t be able to install them on an unjailbroken phone (such programs, of course, are not sold in the official App Store).
It is quite difficult for an untrained user to determine that a “bug” lives on a phone. However, there are several signs that can indirectly confirm the presence of "".
1. High battery temperature
If your phone's battery is hot, it means it is actively discharging. This is normal during a call, but if no one has touched the device for a couple of hours, and it still remains noticeably warm, then something is happening inside it, for example, spyware is running.
2. Your phone runs out of battery too quickly
This point follows from the previous one: if the battery discharges too quickly, especially if the phone has not been used more than usual, it means that some potentially dangerous application is “running” inside it. However, remember that over time, batteries “wear out” and a decrease in operating time is normal. You only need to think about it if a week ago the phone worked on one charge for three days, but now it only works for one.
3. Delay when turning off
Pay attention to the delay when turning off the phone. If this process takes a suspiciously long time, is accompanied by blinking of the backlight (it may remain on for some time after turning off), or shutdown fails at all, then something is happening to the phone. These could, of course, be ordinary technical problems, but more unpleasant options cannot be ruled out.
4. General strange behavior
If the phone spontaneously turns on the screen backlight, turns off, reboots, installs or launches programs, then most likely you are already “under the hood”. Of course, here, too, we cannot rule out some malfunctions in the operation of the operating system, but we cannot ignore this.
5. Interference and interference
Interference can be of two types: those that you hear during a conversation, and those that occur when you bring the phone near, for example, audio speakers. In the first case, the echo or any other noise (clicks, hissing, etc.) that accompanies your conversation with any subscriber at any time is suspicious. Sometimes the appearance of interference is the result of poor signal reception or other similar problems, but if the noise is heard everywhere and not for the first day, then this is a reason for concern.
The second case is when the phone's transmitting antenna points to other devices, primarily to speakers or speakers. You've probably heard this "gurgling" sound many times. It occurs during a conversation, as well as in standby mode at short intervals when the phone accesses the base station. Continuous gurgling when no one is talking on the phone is considered abnormal. This may mean that the spy program has contacted another phone and is transmitting all surrounding sounds to it.
Why is there an echo on my phone?
Usually, in expensive devices, the echo effect in the phone is rarely observed. This is mainly the case with inexpensive handsets made in China. You are unlikely to be able to rid your phone of echo on your own, so either change your phone or get used to this unique connection.
There are several reasons:
Most likely you have technical problems with your phone; it is possible that the speaker is not working properly.
The second reason is unlikely, of course, but maybe you are being bugged.
Maybe you dropped your phone or got water on it.
Or you need to buy a cell phone with echo protection. Some cell phones have the ability to block this issue after repair. However, you most likely don’t want expensive repairs and don’t want to buy a new phone either...
Do you hear an echo when dialing a phone number? If you hear an echo, you can mute the call. The echo is caused by the inability to fully connect two mobile phones together. That is, due to a weak signal, an echo begins in the phone.
Dial the number again and if this time there is no echo, until a secure connection is created. There will be an echo or not, it is not possible to predict, and it happens now and then. Disabling the calling phone and redialing the number is the only way to solve the problem without purchasing a phone with echo protection.
An echo in a phone can appear as a result of a mechanical impact - for example, a fall - then the microphone or speaker in the phone moves and the microphone transmits what is heard from the speaker - hence the echo. This also happens after poor quality repairs.
Problems with the phone speaker. You need to take it to a mobile phone repair shop and have the speaker cleaned.
Echo in the phone In some phone models it can be observed quite often.
First of all, you need to contact the service center. It’s not for you to delve into it yourself.
If they don’t help, then you just need to get rid of such a phone using methods known to everyone.
The reason for the echo in the phone may be that the microphone receives the sound produced by the speaker and sends it again through a complex electronics system to the speaker. Glitch in person.
But it happens that all you need to do is turn down the speaker volume or just call back again and echo in the phone disappears.
during a conversation may be for various reasons
Sound from the speaker may echo into the microphone due to:
This effect is called acoustic coupling and occurs when the sound received from the interlocutor and reproduced by the speaker of your phone is perceived by the microphone and transmitted back to your interlocutor. This effect occurs when there are errors in the design of the phone case and the desire to save on a special electronic element - an echo suppressor, which monitors this problem and eliminates it.
Most often, this is the case with inexpensive LG devices, as well as all sorts of Nonames collected in Uncle Liao’s shed.
Telephone echo can often be found in cheap Chinese counterfeits. Sometimes it helps to simply call the subscriber back. However, if the echo in the phone is constant, then you need to either contact customer service or change the phone.
Yes, I have encountered such a phenomenon that while there are even beeps and the subscriber has not picked up the phone, but you can hear yourself well, this is because of the small phone and the loud speaker (that is, the microphone hears what the speaker is playing), usually after repairs this happens due to a violation of the internal insulation during disassembly - you can line the speaker with a soft cloth and direct the sound only to the output holes.
It's no secret that a mobile phone can become the object of surveillance by a certain person, who can thus disseminate confidential information. Eavesdropping on a mobile phone with the help of spyware that has quietly “settled” on your mobile device is especially dangerous. And while you are calmly talking on the phone, someone will use you to reveal important information, be it your personal life or confidential data of the company where you work.
While scandals and reports arise in the United States that another Russian intelligence group of spies has allegedly been defeated, ordinary citizens of many countries are having fun with “innocent” wiretapping of the phones of their friends and relatives. Anyway eavesdropping on mobile devices without the consent of both parties is prohibited by the legislation of most countries of the world.
It’s worth noting right away that it is impossible to intercept a conversation signal between mobile phones using an “antenna with a box” due to the fact that the data transmission channel between devices is quite well encrypted. The ability to intercept a channel is available only to mobile operators with the assistance of intelligence agencies. However, you can keep track of the person you are interested in using less complex technological solutions.
Installing spyware on someone else's phone will not be difficult, since there are many applications on the Internet for listening and spying on a mobile device. They are able to secretly work on the victim’s phone and transmit information in a variety of ways: sending SMS messages with your coordinates, making hidden audio and video recordings, sending data by email, and even taking pictures with a standard phone camera.
The risk group includes devices that use Windows Mobile and Symbian as OS. The bug can also be installed on the iPhone, but before that it needs to be hacked.
It is quite difficult for an ordinary user to determine whether his phone is tapped or not. But some signs of unusual behavior of a mobile device should alert you.
1. High battery temperature. If your phone's battery temperature has risen and does not cool down for a long time after a conversation, you should think about why this is happening. Perhaps you simply forgot to close some application that places a heavy load on the device's RAM and thus uses more energy than in normal mode. If you still haven’t found this program, then there is a possibility that someone planted a bug on your phone, which is hidden from your eyes in every possible way. The moment the battery temperature is kept at a high enough level, the phone battery quickly runs out. However, the rapid discharge of a mobile device’s battery can also be explained by its service life. The older he is, the less time he can work.
2. Strange behavior of the phone. Inappropriate behavior of a mobile phone, which is expressed by random changes in the backlight, turning off, launching random applications and other problems, may not be caused by spyware. Perhaps such “lags” are caused by a malfunction of the operating system, the use of pirated programs, or the acquisition of virus software. In such cases, you need to pay special attention, because you don’t know what’s better - a spy program that monitors your every move, or a dangerous virus, after which you will need to “sweat” a lot to get your phone out of the dead.
3. Delays when turning the phone on and off. If your phone takes longer to turn on/off, something is wrong. It’s possible that some spyware is loaded during startup of the device’s operating system. In some cases, when the device is turned off, the backlight does not go out for a long time.
4. Extraneous noise during a conversation. Usually, while listening, when a conversation is taking place, the mobile phone makes an echo or some kind of monotonous atypical noise that you have not noticed before. Perhaps this is just interference caused by poor signal reception, but if the noise is heard constantly and for several days, then this is a reason for concern. It is obvious that you are being watched when the device begins to make strange sounds during inactivity.
5. Constant interference. You've probably sometimes noticed that a peculiar "gurgling" sound occurs near speakers and speakers during a conversation. There is no need to worry about this - this is normal. The thing is that during calls and in standby mode (with a certain interval) the phone contacts the operator’s base station. It is considered abnormal when a mobile device begins to make similar sounds for a long time after you have finished a call. This can only mean one thing - the spy application has contacted another device and is starting to transmit all surrounding sounds to it.
Many users encounter a problem when their Android phone or tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.
For example, the device has problems with the fact that during a conversation (call) any distortion or defects in sound transmission/reproduction appear. The reason for this may be:
2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)
However, do not rush to get upset - in 90% of cases with problems with the operation of the data transmission and playback system and directly adjusting and adjusting incoming and outgoing calls, the smartphone or tablet based on Android is to blame software glitch which you can easily fix on your own.
Fixing a software glitch:
Method 1. Quite simple - go to "settings", find there "backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.
Method 2.
Method 3.
Changing the device software, or as it is also called "flashing". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.
If none of the methods brings results, unfortunately, you will have to contact the Service Center to repair your tablet or smartphone.
phoning when talking on a phone or tablet / when talking on a smartphone or tablet on the Android platform, you can hear yourself, phoning, crackling, or any other defects appear. What to do and how to fix it.
What should you do if you hear an echo on your phone during a conversation? And in general, why is this phenomenon observed? These questions arise among citizens more and more often. In fact, telephone echo can be due to various reasons. Sometimes it is possible to resolve a situation without any problems, but in some cases this cannot be done. In general, if a subscriber has the problem described, he will have to go through several options for the development of events, the diagnosis of which is very difficult without outside help. So what should you do if you hear an echo during a conversation? Why is this happening? How dangerous is the phenomenon?
The first step is to understand how realistic it is to solve the problem. Perhaps there is no way to eliminate the echo in the handset that is interfering with the conversation?
As practice shows, echo during a telephone conversation is a phenomenon that usually needs to be corrected. And without radical actions. Accordingly, do not be alarmed if this problem occurs. But what causes an echo in the tube? And what to do in this or that case?
The most obvious option is a manufacturing defect. Relevant for new phones. It is likely that the device was faulty to begin with. As a result, an echo is heard when talking.
It is worth paying attention to the fact that the problem begins to bother the buyer immediately after the first call. That is, from the very beginning. You can act in several ways:
However, marriage is only one of the reasons. It has already been said that it is detected immediately after you start using the phone. What situations occur most often in real life?
Why can I hear an echo on my phone during a conversation? Sometimes subscribers complain about exactly this situation. Moreover, regardless of the services of which operator they use. Why can you hear your interlocutor or yourself repeatedly?
It is likely that the volume of sounds is to blame. Or, as people say, phone settings. The other person's speaker or microphone is too loud. Because of this, the mentioned problem occurs.
Why is there an echo? If the device has been in use for a long time, it is possible that a bug is installed on the mobile phone. He helps someone wiretap phone conversations. This is where the echo comes from.
Fortunately, such a situation is extremely rare. If you suspect wiretapping, you can take your mobile phone to a service center, report your suspicions and wait for the diagnostics and repairs to be completed. This technique is the fastest, most logical and simplest solution. After all, it is very difficult to get rid of a bug on your own.
If an echo occurs while talking on the phone, do not be alarmed. And immediately think that a low-quality product was purchased, too. The thing is that each mobile phone has its own “stuffing”. That is, all phones are designed differently. The cause of the problem may be a factory feature.
That is, the phone was originally assembled in such a way that an echo would be heard when working with a mobile network. Mainly relevant for older models of gadgets. The solution is only 2 options:
There are no other solutions for this situation. How to remove echo on your phone when talking? It all depends on the cause of the problem. What other control methods should you pay attention to? For example, what if all the previously listed scenarios do not explain the resulting echo? 
In such a situation, only a service center will help. Or buying a new phone. But we are not talking about the features of the mobile phone device. An echo on the phone during a conversation may occur if the speaker is broken.
A fairly common problem faced by subscribers who do not monitor their mobile phones. If your phone has been dropped or dropped into water, it is likely that an echo problem will occur.
By the way, if you leave this phenomenon unattended, eventually the speaker will refuse to work at all. That is why, after some negative impact on the phone and the appearance of the specified problem, you need to contact a service center. There the speaker will either be repaired or replaced. Luckily, in most cases you don't need to buy a new phone. But you shouldn’t expect that a repaired speaker will last a long time.
An echo in the phone during a conversation can occur if the seal of the gadget’s case is broken. The situation does not occur too often, but it is very problematic to deal with it.
If the subscriber is wondering how to get rid of the resulting echo, you can suggest the following steps:
But the possible options don’t end there either. There is another fairly common reason why you will hear an echo in the phone when talking to the interlocutor. You also need to know about it.
We are talking about the work of a mobile operator. In every city, such companies have a huge number of transmission lines. Because of this, the signal is blocked for some operators in certain places. This is where the echo appears in the phone during a conversation.
There are several ways to fight. Usually at least one of them is effective:
Perhaps this is where we can complete all the most common reasons for the appearance of an echo during a conversation. It is now clear what to do in this or that case. In reality, everything is not as scary as it seems.
However, before going through all the previously listed problems, it is recommended to use a little trick. Sometimes you hear an echo when talking on your phone due to minor system glitches. Both on the line with the operator and in the mobile phone itself.
Turning the phone off and on again will help correct the situation. Or you can end the call and call the other party again. It is still recommended to reboot the smartphone. This technique, as practice shows, helps quite often.
What conclusions should be drawn? There are many reasons why an echo occurs during a conversation. It can be very difficult to diagnose it yourself. But most often this phenomenon occurs due to:
Most often the problem can be dealt with. And as already mentioned, only in some cases it is necessary to act radically.
What is an echo and where does it come from?
Some cellular users are faced with the fact that when talking on a mobile phone, in addition to the interlocutor, they also hear themselves with some delay. The echo effect in mobile phones creates certain inconveniences when communicating. Who should I contact to solve this problem? What could be the reason? There is no clear answer to these questions, so we are publishing this material designed to help those users of digital devices (mobile phones) for whom convenience and comfort in the operation of mobile equipment play an important role.
What is an echo and where does it come from?
There are two types of echo - linear and acoustic. Linear is created by electrical circuits connected to wire lines. Acoustic echo is a problem for all devices that read and reproduce sound. It occurs when sound is reflected, due to it entering the microphone from an external speaker. In this case, the interlocutor hears not only the speech of the other subscriber, but also his own, returned to him as an acoustic echo.
Consequently, the causes of echo can also be divided into two groups. The first is subscriber equipment (your telephone) and its accessories, the second is the equipment of your operator, or the company providing wired telephone services.
The first group of reasons. Since the speaker and microphone of your device are located in the same housing, under certain conditions an acoustic echo may occur. Sound from the speaker can get into the microphone for two reasons: the first is the lack of a “tightness” of the connection between the speaker and the hole for it in the housing, due to which the sound from this speaker spreads throughout the housing and enters the speaker. This phenomenon can be caused either by mechanical loosening of the housing during operation, or by its design; the second is the cover. After some time has passed since the start of use, cases tend to “wear out” somewhat, due to which a certain amount of free space is formed between the case and the phone body, which helps to shield sound from the speaker to the microphone.
In the second group of reasons, the following can be distinguished: the first is the transceiver of the base stations of your operator, near which you are located, the second is the wired telephone provider whose subscriber you are talking to. This happens due to the reflection of part of the signal when moving from the local line to the main line.
How to determine the cause of the echo effect in your mobile phone.
To effectively solve a problem, it is necessary to accurately determine the cause of its occurrence. Unfortunately, this is unlikely to be done with 100% accuracy, but the probability is still high.
So, if the echo is a constant phenomenon or, on the contrary, it is impossible to trace any pattern in its appearance, then the reason is most likely your device. To be sure of this, try turning down the speaker volume. In cases where the echo disappears after this, the cause of its occurrence was in the phone. Also try removing the cover. The echo disappeared - the case is the reason.
If the echo occurs in certain places, or when making calls to some, or occurs for a certain period of time, then your terminal should not be blamed. One of the second group of reasons is at work here. The BS is to blame if an echo occurs in some place, and it is not to blame if, when an echo appears, you contact a landline telephone. When you experience an echo, try a SIM card from another operator in the same place. The echo disappeared - the reason for the NDE, no - no.
How to deal with this.
If the problem is in your device, the solutions are as follows: reduce the volume of the speaker; if the problem is in the case, if this does not help, there is only one way out - replacing the phone. The reason is in the cover - the solution to such a problem, as you might guess, is to refuse to use the cover, or, if this option is not acceptable, to replace it with a new, denser one.
If the operator is to blame for your unbearable torment, then you need to call the subscriber service and report the place where you constantly feel deficiencies in the quality of communication. Your application will be accepted, but when the reason will be eliminated (and whether it will be eliminated) is unknown. The average user has only one way to influence the operator - call and call. Or, if everything is really bad, you can change the operator, after making sure that you will not have similar problems with the new one.
To combat the echo that occurs when calling a regular landline phone, there are special echo suppressors. These devices identify human speech coming from one end of the connection and suppress all signals coming in the opposite direction.
As you can see, the problem is not solved without costs in all cases, but it can still be solved. By the way, echoes can occur due to the fault of listening devices; here you need to read less books about spies.
The so-called “echo” that your interlocutor hears during a conversation is caused by:
a) The “crosstalk” of the signal is due to poor soldering of the microphone, its cable and contacts, sometimes through an overly sensitive microphone. Or the rubber speaker gasket has come out of place. As a result, the speaker sound penetrates the phone and enters the noise canceling microphone instead of passing only through the speaker hole on the front of the handset. All of the above is a factory defect.
b) Noise reduction (the fact is that starting with official firmware 2.3.4, the noise reduction function is active by default, but there is no option for adjusting it)
Ways out of the situation:
a) MARRIAGE. Check soldering, cable and contacts. In case the rubber gasket is to blame. That is a very simple way out. The photo shows two components influencing each other: “A” is a noise reduction microphone. Make sure that the elastic band covering it sits properly in place. "B" - speaker held in its seat:
Move the speaker up and down a little until you can lift it up. Clean the speaker housing and its seat from all dirt, because they prevent the speaker from sitting properly in the socket. Reinstall the speaker and press it firmly until it fits well into the socket. The rubber seal surrounding the speaker should be held tightly in place to isolate the insides of the phone from sound. Now we need a piece of paper 0.5mm thick and 5x12mm in size. It needs to be placed on top of the speaker. A business card is very suitable for this purpose, because their thickness is just right. The paper should cover the area indicated by the red rectangle "C":
Reassemble the phone by replacing the back cover and tightening all the screws. Now the piece of paper additionally presses the speaker into its seat, preventing it from creating an echo in the phone.
Articles and publications
Unfortunately, mobile technology has come so far that wiretapping a mobile phone has become not too difficult. Anyone who is not too lazy can implement it and who naturally has an interest in it. But there are several ways to prevent invasion of the owner's privacy. In this article we will define the main points that will allow you to determine whether the phone is tapped or not.
1. Battery temperature.
Touch your phone when not in use. If the battery is warm or hot, it means it is still in use. Don't forget the factor that heat is generated due to overuse. The battery will only be hot if the mobile phone has been used for some time.
2. The phone discharges too quickly.
If you notice that you are charging your phone much more often than usual, this is a reason to be concerned. In this case, there is a high probability that someone else used it. If your phone is wiretapped, its battery drains much faster. Such a phone records all conversations in the room, even if at first glance it is lying idle.
But if the phone is more than a year old, the battery capacity will no longer be the same due to the intensity of use. In this case, the article “How to extend the operating time of your mobile phone” is just for you.
3. Delay during shutdown.
If you turn off your mobile phone and see a delay, a backlight that does not go out for a certain time, or the phone simply refuses to turn off, all these signs indicate possible eavesdropping.
4. Unexplained activity.
While the phone is operating, the backlight suddenly lights up for no reason, various applications are loaded, and it spontaneously turns on or off - this is a high probability of using the phone without your knowledge. Perhaps someone is manipulating the phone remotely. But such a failure can also occur due to network interference.
5. Constant background noise.
Typically, a phone that is tapped interferes with conversations. If you hear an unusual noise from your mobile phone when you are not using it, this is a signal that you are being watched.
6. Frequent interference.
If your phone is located near a TV or other electrical appliances, it may interfere with them due to the presence of foreign objects in its case. In some cases, this is normal, but if you use a phone. If not, then you are “under the hood.”
7. Learn to be a disinformer!
If you are absolutely sure that you are the owner of the phone being tapped, try to give out invented information in order to bring the spy to the surface. Share the secret of your fear with someone close to you. Use your phone to transmit false information; if it becomes known to outsiders, you have probably been tapped.
