and Android.

Many users face the problem when phone either android 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 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.

Fixing a software bug:

Method 1. Pretty simple - go to "settings", find there "backup and reset" in which you choose full reset settings to delete all data. Be careful, using this method often turns out to be effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.

Method 2.

Based on solving problems with communication and network reception phone ov and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all, it controls the system functions, corrects, and fixes all possible settings and synchronization errors, a small, easy-to-use, free utility for Android devices. You can download the application from Google Play and see its additional options in the description. After installing the application, it remains only to launch it. Further, from you, in principle, nothing more is required. The application will take full control of the device functions. (By the way, among other things, the gadget will start charging 20% ​​faster, and its performance will also increase significantly, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system runs on 50% faster.)

• In addition, it is worth cleaning the system with a NORMAL antivirus. Best of all, it copes with this task kaspersky antivirus , which you can download. Unlike the “multi-cleaner”, Kaspersky Lab’s software is paid, so if you don’t have the opportunity to install such protection, you can skip this step ...

Method 3.

Changing the device software, or, as it is also called "re firmware ". This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer's website of your device, download the utilities necessary for the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brought results, unfortunately, you will have to contact the Service Center for repair of your tablet a or smartphone a.

The conversation (call) is interrupted when calling from a smartphone or Android tablet.

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 took advantage of 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.
