Why is the call dropped on the phone. The conversation (call) is interrupted when calling from an Android smartphone or tablet

Articles and Lifehacks

From time to time, device owners face a problem when the phone turns off unexpectedly and spontaneously during a conversation. After that, you have to take out the battery (if it is removable, if not, just reboot), turn on the phone and re-connect with the interlocutor. At the same time, the charge level is sufficient for making / receiving calls and for performing other manipulations.

Reasons for turning off the phone during a call

The shutdown may be triggered by a so-called protection mechanism that is activated to prevent a more serious problem with the machine's components.
The reason for turning off the gadget may be a failure associated with both the software of the device and its technical part.
It can also happen as a result of installing a new and incorrectly working firmware version.
Turning off the phone at the time of the conversation can also be caused by mechanical damage that was done earlier: the device fell or water got into it, the contacts were clogged with dust.
It also happens that the charge control indicator shows a false battery level during a call, i.e. a little (or even a lot) more than it really is.

What to do if the phone turns off

To begin with, you still need to try to restart the device, or even better, remove the battery (if it is in the device), turn on the phone again and make the call again.
Sometimes it helps to completely restore the phone's battery, or even in particularly difficult cases, replacing the original battery, which wears out over time and may well be the reason that the mobile device turns off during a conversation.
You can check it like this: if at the moment when the phone is charging, it does not turn off during the conversation, then the problem is most likely in the faulty battery.
If the problem recurs, you need to take the phone to a specialist who will diagnose and establish the cause of the breakdown. The service center will help to eliminate the consequences of mechanical damage, solder the components or warm up the microcircuit of the mobile phone, check the battery indicator or reflash the device.

As a conclusion, I would like to say that if a forced reboot and a full charge of the battery did not help, it is better to seek help from professionals, and not try to solve something at home, because this can only harm and aggravate the problem.

If there is no opportunity or do not want to talk, subscribers resort to different methods.

The simplest reason why it is impossible to reach the subscriber is that his phone is turned off, or the subscriber himself is out of the network coverage area.

If the call goes through, but the caller does not pick up the phone, it is possible that he cannot / does not want to talk, or his smartphone is in silent mode, or the person has used the capabilities of his smartphone by selecting the "priority" option. For example, owners of Sony devices have such an opportunity - by adjusting the volume of the smartphone, you can select one of the modes "silent", "priority", "sound". Just the "priority" option allows you to filter calls, skipping only those that are in the address book.

The "black list" formed by the subscriber will not allow unwanted people to get through to him. If only one beep passes during an outgoing call, and then the call is dropped, the caller is probably on such a list; or he hears short beeps, as if the number is busy, or the message "the subscriber's device is turned off or is out of network coverage."

This type of communication is not available to the subscriber. What does this mean? - www.site/all_question/other/2016/April/72499/187718

And a completely different picture, if the outgoing call is dropped immediately, and the caller does not hear a single beep.
In this case, it is possible that the subscriber used the services of a mobile operator and turned off all incoming calls; activated the service "prohibition of receiving calls in roaming". In this case, the subscriber can receive SMS messages (that is, they can reach the subscriber), if he has not disabled them too.

The "call barring" service (the so-called "black list"), not only incoming, but also outgoing, is offered to be connected by all mobile operators.

After the service is activated, you can independently add those numbers that are considered as such to the list for unwanted calls. It is also possible to block an unwanted number permanently.

The inability to reach the subscriber may be due to the fact that he has the iVoiceCallMaster program installed, with the help of which all unnecessary or unwanted numbers are forwarded to a SIM card that simply does not work.

There are cases when you can not get through to the subscriber, because the "blocking of incoming / outgoing calls" is enabled in the settings of his smartphone.
For an iPhone, it helps to enable the "show my number" option in the settings so that calls go through.
If the problem with your smartphone is that it does not miss outgoing calls, you can restart it (it is useful to do this periodically), as well as turn off / on the 3G function (maybe it's a "raw" firmware).

For the Android operating system, a program has long been invented that cuts off unnecessary incoming calls or redirects the caller to voice mail. The program is called Current Caller ID and is suitable not only for smartphones, but also for tablets. To take advantage of this opportunity, the Current Caller ID application must be installed on your gadget.

There is an opinion on the Internet that simply the "black list" option, without specific numbers in it, does not allow you to reach the subscriber, and only when it is turned off, the calls go through, but this is a single opinion that needs to be verified.

If the phone does not receive calls, the reason may lie in the failure of the network settings or the device as a whole. Let's see how we can solve this problem.

Method number 1. Selecting the correct network settings

In some cases, choosing the right signal source helps. It is not known for what reasons failures in such settings occur, but they do occur and need to be addressed.

Due to such failures, situations arise when the phone does not receive incoming calls and / or does not ring itself. That is, the call is dropped or other problems occur.

Here's what you need to do:

Go to settings and open the "Mobile networks" menu there.
Select "Network Operators".

First, click the "Search for networks" button. All available will appear below. Choose the one you need. You can recognize it by its name.

Attention! If you have two SIM cards, go to the tab of the one with which the problem in question is related.

If you use 3G, be sure to select the appropriate mode for the SIM card with which the problem is associated in the "Mobile networks" menu. This is done by clicking on the "SIM network mode" item and selecting the desired option from the list that appears.

Clue: 3G is WCDMA. It will be called that on the menu.

Problem not solved? Try restarting your phone. If nothing has changed then, you will have to do a reset.

Method number 2. Reset

Important! Before you perform any kind of reset, be sure to copy all important data to a USB flash drive or transfer it to the cloud. In some species, they will be removed.

In more detail, you will need to use three types of reset - for network settings (most likely, the problem is in them), smartphone settings and data.

To do this, follow these steps:

Open the settings and go to the "Backup and reset" section.
There, at the very bottom, you will see the three reset options discussed above. First, perform "Reset network settings" (click on this item and confirm the action). Reboot the device.
If nothing has changed, use "Reset Settings" and "Reset Data". Be sure to reboot after each.

If after that the smartphone does not receive calls, but calls or vice versa, that is, the problem still occurs, you will have to perform a hard reset, that is, a complete reset of the device.

Method number 3. Full device reset

This method differs in that not just settings or data are reset, but absolutely the entire operating system. The phone is reset to the factory state. After such a procedure, the OS will be completely clean and, of course, there can be no failures in it.

Before performing a hard reset, be sure to make sure that all important information has been copied to a safe place so that it can be restored at any time.

The full reset procedure itself is described in detail (method 5). It is important to take such a procedure extremely responsibly and do everything as described in the article. If you do something wrong, the device can be turned into a brick. Therefore, if possible, it is better to take it to repair or entrust the reset to professionals.

“Why can’t they call me, although my phone is on” is a common question asked by subscribers of different operators (MTS, Beeline, Tele2, Megafon). Most often, the caller receives short beeps (busy) or a return message that "Subscriber is temporarily unavailable." It also happens that with a full antenna, the call does not go through, a little later only messages are received notifying about missed calls. Today we will talk about all the sources of a failure in which it is impossible to get through.

Causes of communication failure with the subscriber

It is impossible to answer this question in advance. It is necessary to comprehensively study all the circumstances, on the basis of which conclusions can be drawn. We immediately note the most popular reasons:

malfunction and / or damage to the SIM card;
OS damage, firmware failures, software glitches;
incorrect settings of the communication module or other hardware failures;
operator problems are the most common cause.

What do you do if you can't get through?

As a rule, the cause is found out by excluding variants. For convenience, let's look at each source of the problem separately. Let's start with the study of Sims.

Malfunction or damage to the SIM card: how to determine?

A simple and logical solution would be the following procedure:

Partial failure or damage may prevent the call from being made. By inserting the card into another phone, the story repeats itself exactly. At the same time, another SIM card in my own phone works well and without problems. In this case, you just need to contact the call center and make a request to replace the SIM card with the same number.

Software failure

Glitches and bugs with intensive use of the device occur regularly. You can determine their scale as follows.

Communication module and hardware failures

To begin with, it is worth saying that some smartphones with two SIM cards have only one radio module. Accordingly, only one of the cards will be “on the network” then. If this is not your case, then try simply restarting the device or entering flight mode. Helped, but the problem recurs regularly? Use a hard reset or flash the device with stock firmware from. site. Such moments are diagnosed quite problematic:

OS problems

Can a smartphone stop receiving incoming messages after an unsuccessful firmware update? Other malfunctions may also be observed. This occurs due to the use of an inappropriate ROM file (usually custom firmware) or the version of the radio module. The incompatibility is resolved by flashing. If critical damage occurs, you will have to seek help from the service.

System updates that came through the air can also cause failures. Therefore, it may be effective to roll back the operating system to a previous version, followed by disabling auto-update.

Operator malfunctions

The lack of a quality network is a common thing. Quite often, rather weak equipment is installed in a densely populated area, which is unable to properly serve customers. The problem is especially acute on holidays and applies to all popular operators - MTS, Beeline, Tele2, Megafon, etc.
Another option is the lack of coverage or repair work. One way or another, the subscriber temporarily leaves the network coverage area. It is quite logical that in this case the signal in the phone is either absent or at a minimum.
The operator can block the subscriber for violations of the rules for using the network (hooliganism, spam, etc.) or in the absence of replenishment for a certain period of time (usually a year). The message from the operator of the caller refers specifically to the blocking.

To improve the quality of communication, you can use special software or connected equipment. Software capabilities are very limited, so we are not talking about improving communication, but about optimizing it. There are enough programs in the Playmarket that allow you to automatically set your phone to the desired mode of operation - for example, "Quick Settings".

The connected equipment is selected depending on the distance from the tower and the presence of interference on the line. Some professional systems allow you to really improve the quality of communication in a small area at a distance of 30-50 km from the tower. Often they are used by owners of country houses.
If you find a malfunction after flashing, then be sure to check if the IMEI of the phone matches. You can find it out by dialing the combination *#06#, and you can compare the code with the number indicated on the box or under the battery. A broken IMEI can be restored - there are a lot of video instructions on this subject.
If the VAZ is calling, and you are always busy, then turn off the mobile Internet - completely! And all synchronization too. Especially if the operator transmits data over a 2G, 3G channel, then it is sometimes impossible to receive calls using the Internet. At least on standard hardware.
There is a possibility that incoming calls are prohibited on the phone. This can be done in the device itself, for example, in the Mode settings, or through the operator. In the first case, disabling this function or any type of reset helps, and in the second, a call to the operator.

Conclusion

In most cases, the problems are short-lived, regardless of the cause. If you have tried all the proposed methods and tips, but they can’t get through to you and the phone is on, then most likely we are talking about a deeper breakdown that can be diagnosed at the service center.

Many users face the problem when an Android phone or tablet starts to act 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 the call is constantly or periodically terminated or ends by itself. The reason for this may be:

1st: Software failure- i.e. the problem is a software glitch

2nd: hardware failure- i.e. the problem lies in the "hardware" (i.e. - replacement or restoration of spare parts of the gadget is required)

However, do not rush to get upset - in 90% of cases with problems connections on call smartphone a or android tablet is to blame software failure, which you can fix on your own.
