Lenovo a1000 public alert. This is how your group chats are muted. What to do if notifications continue to arrive after disconnecting

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 solutions can be called solutions - they are more like a way 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 also by and large, in our country this function is extremely useless, 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:

Now that's it for sure. 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 system Android.

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 of the operating system Android systems, 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.

Not having a specific addressee 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 specific operator has not only disadvantages (alerts that can arrive every minute are annoying), but also advantages: for example, using mass SMS mailing it is possible to 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.

By installing each application, the smartphone owner agrees with requests for access to certain data and device capabilities, including a notification system. Thanks to this, you can be sure that you will not really miss important messages and reminders, however some mobile software abuses this by distributing promotional or frequent irrelevant alerts.

Get rid of annoying notifications can be done in two ways - either using the Android system, or through the settings inside the application itself. The first case is only suitable for smartphones based on version 4.1 and higher, while the second does not depend on the OS modification.

System disable notifications

The ability to configure alerts has begun to be implemented from devices on Android based Jelly Bean, on such devices you can either completely disable notifications for each separate application, or enable everything. In Android 6 there are already more fine tuning, allowing you to adjust frequency, sound and other parameters.

Also, notifications from this application can be moved to the “Important” category, and in this case they will make themselves felt even in “Do Not Disturb” mode. By setting a frequency limit, you will not hear more than one alert within a specified period time (from 10 seconds to 30 minutes).
