Alert to the population stolitsa. Block unknown people from interacting without reason

Question: Good afternoon. A couple of days ago I bought a SIM card from an operator that supports 3G, because... I need a quick one Mobile Internet. And suddenly I was faced with an unexpected problem: some strange messages with hieroglyphs called “Public Alert” began to arrive on my phone. Messages come in hundreds and you have to delete them one by one. But the most annoying thing is not even this, but the fact that these notifications instantly drain the battery. After all, the phone constantly beeps and vibrates. Therefore, I have to charge my phone 3 times a day - both at home and at work.

I also understand that it somehow depends on my movement around the city - in some place the phone is at rest, and in another there may be silence again. There may be silence for a couple of hours, and then the pop-up “population alert” messages begin to arrive again. I have a Lenovo A1000 smartphone, which I bought a month ago. Before this, we used another operator that operates in 2G mode, and there were no such problems on the same smartphone.

So, in this article we will try to collect all possible solutions. Unfortunately, one thing helps some, something completely different helps others. Some decisions can be conditionally called decisions - these are rather a way work around the problem.

What is Cell Broadcast?

Cell Broadcast (also known as “Broadcast messages”, “Network messages” or “BS Information”) is standard function GSM network designed to make life easier for the subscriber. Often it serves to display the name of the current metro station, the nearest settlement or telephone code terrain. On older phones like the Nokia 3310, network information was conveniently displayed on the screen under the operator name. But on new smartphones broadcast messages come as SMS: from sound signal and appear in the Messages app. It is worth remembering that the enabled Cell Broadcast function will in any case further drain the battery.

How to turn off public notification

Solution #1. Disable Cell Broadcast

On Lenovo smartphones:

Messages → Settings → SMS/MMS settings → Default message manager → Public notification.
Select the SIM card for which you want to disable notifications and uncheck the boxes.

Disabling messages from the base station in Samsung Galaxy:

Go to Messages.
Press the Menu key (or long press the Recent Applications).
Select Settings.
Network messages (or Network message settings).
Click the switch or uncheck the box to turn off:

Solution #2. Change broadcast channel

Sign in to Messages.
Bring up the menu and select Settings.
Select Channel configuration→ Reception channels → My channel.
After that, click Add channel and enter the number (let's say 10). By default, channel No. 50 is used, so you need to specify some other one.

Solution #3. Move the card to another slot

This method really helped my friend turn off the “population alert” spam with hieroglyphs on Lenovo smartphone A1000 with Android 5. Moreover, the interesting thing is that in the second slot the SIM card also works in full 3G mode (for some models of dual-SIM devices, only one of the two slots can work in 3G mode). It is not entirely clear why this happens, but the solution helped get rid of spam.

Solution #4. Change 3G mode to 2G

If none of the above helped, then finally I’ll tell you about one more way to get rid of annoying notification population on your phone. Switch the card to 2G mode. On some operators this solves the problem. Naturally, the data transfer speed will be reduced.

Go to Settings → Other networks → Mobile networks→ Network mode.
Select 2G or GSM Only.

This is more of a crutch than a solution... However, if you do not use the Internet on your phone, then you have an additional chance to get rid of broadcast spam.

Afterword

In conclusion, I can say one more thing. They write on the Internet that it is possible to disable the public notification on the operator’s side by executing some USSD command, but we were unable to find such a solution. Operators refer this problem to the smartphone manufacturer. Therefore, I would really like to hear the opinion of Lenovo representatives regarding this problem on their devices.

First of all, the “Public Alert” notification is aimed at countries in which there is a high risk of natural disasters, some kind of accidents, and so on. Thanks to this functionality, people with Android smartphones should receive alerts with any information that is valuable to them.

In our country, something went wrong with the function and it does not work as it should. As a rule, it only sends ridiculous notifications with the operator’s name and illegible symbols that look like a code. But by and large, this function is extremely useless in our country, but in some countries it is very relevant.

Many manufacturers limit such notifications on their devices due to simple unnecessary use. So, this is why the problem with such messages is not so common on smartphones from Samsung, Xiaomi and others. But if you suddenly encounter it, then below we present a simple solution.

To disable such notification you do not need root rights. Everything is done without any risks and in a couple of seconds.

So, to disable the “Public Alert” notification, you should follow a few simple steps:

That's all. Now notifications will not arrive.

What should I do if notifications continue to arrive after disconnecting?

If suddenly they appear again, then do the following:

That's it now. You will no longer receive any emergency notifications.

Why don't I have menu options to turn off notifications?

The considered disabling method does not work on all devices, because not all have these same menus. The fact is that many manufacturers hide the Public Alert program or do not allow users to manage its permissions.

If suddenly you were unable to repeat the operation and disable the service according to our instructions, make sure that you have current version operating room Android systems.

The permission management feature became available in version 7.0 Nougat. If the Android version is on your mobile device below - such actions will not be repeated. In this case, you will have to set root access to the device and completely delete the application with the notification.

In addition, even if you have the current version operating system Android, perhaps the firmware itself does not allow such actions, or the menu navigation has been greatly changed, and the function for setting permissions is located in some other place.

Increasingly, owners Android devices began to encounter broadcast messages. Moreover, it is not possible to take them and simply get rid of them. Usually you have to delete them because of duty, but after that they still arrive on the device like an avalanche. As a result, such “surprises” bring not only the owner of the device to the brink of madness, but also the smartphone itself begins to slow down terribly.

Three ways to disable public notification on Android

Don't be upset if you think that such messages will never be deleted. At the same time, in order to get rid of numerous spam, you need to follow the steps described below.

Method 1: Disable Push Messages

The first thing to start with is to find the “Messages” icon on the desktop and click it. Going there, look for “Options” or “Settings”. Having opened the found menu, you must select the section “ Information messages", on some devices they may be called "Push messages", or "Network messages". Next, after unchecking all the boxes, you will have to reboot your smartphone.

Method 2: Removing spam from information messages

Go to “Messages” and look for the “Options” or “Settings” item. After that, go to the found menu and look for “SMS/MMS Settings” there. Then you need to go to “Settings” information messages" In the same way, uncheck all the boxes and reboot the device.

Method 3: Turn off the public notification function

We go to “Settings”, after which we look for a section with wireless networks. After that, click “More”. In the menu that opens, we look for the section that would be responsible for notifying the population. Uncheck all checkboxes and reboot the device.

Of course, if these methods are too complicated for you, you can try blocking messages using programs Titanium or CDMaid(root). You can also go to the salon mobile communications and disable this newsletter there.

Not having a specific recipient and sent to all devices Android type SMS are called broadcast messages. This mass mailing messages to devices located in the same cell has long been a concern for owners of Android devices.

For the first time this is an innovation in the field high technology was demonstrated in Paris. Sending messages to clients of a certain operator has not only disadvantages (alerts that can arrive every minute are annoying), but also advantages: for example, using mass SMS you can notify a significant part of the population about the occurrence of emergency, For example.

Moreover: by sending messages to clients who are located in the same geographical area, the service provider does not “slow down” the network. If you see incoming batch mailings as a threat to your peace of mind, then you can disable this service either “manually” or with the help of your provider.

Since there are currently quite a lot of Android devices in the hands of the population, we consider it necessary to consider the procedure for disabling the annoying service specifically for different types phones.

We'll talk about android Samsung Galaxy S2 I9 100. A sufficient number of android users are faced with the problem associated with the delivery of unhelpful messages after installing the firmware.

Moreover, if you “go” to the “About the application” section, you still won’t be able to disable the function of receiving notifications.

However, the secret is quite simple: you need to go to “Messaging Application Settings” and uncheck the “Network Messages” section.

If you use this android option like the Samsung Galaxy S3 mini, then, in addition to removing “checkmarks” or “dots” from the message settings, you can use third-party software.

You can disable the appearance of SMS messages that drive the owner of an expensive gadget crazy using the TitaniumBackup programs.
