There are ten situations in which a mobile phone may be monitored. Has your cell phone ever appeared? How to prevent it?

You think eavesdropping will only appear in spy dramas? In fact, it is very close to us in the real society. With the development of the Internet era, users are increasingly dependent on mobile phones. In the high-tech era, while enjoying the convenience brought by science and technology, there are also hidden dangers of being monitored.

The "Snowden" incident broke out in the United States. The NSA of the United States obtained the call records of millions of users every day and monitored confidential information such as emails, chat records, videos and photos of American citizens for six years. Let everyone be in an uproar, only to know that mobile phone monitoring may happen to you or yourself.

I don't know if you have similar experiences. After we have just discussed a topic with our family, colleagues and friends, we will open some smart phone applications and send us advertisements related to the topic we just talked about. For example, when I go to a shopping mall and a shoe store, the clerk recommends products to me. After I came out, I went to a mobile shopping software, and I will see a number of footwear brands on the home page. This kind of incident has happened many times, which makes people feel incredible and fearful.

In order not to be the next monitored object, we usually need to be careful. If the mobile phone encounters these situations, it may be "monitored" by others, and measures must be taken in time.

If these ten situations happen on your mobile phone, you are likely to be monitored!

First, dial your mobile phone number and you can get through.

Under normal circumstances, users can't answer when dialing the mobile phone number, and some voice prompts will appear, such as "the other party is on the phone". If you can connect, then your mobile phone is controlled, and the listener can receive any message outside the mobile phone and all kinds of information operations inside the mobile phone.

Second, there is noise during the call.

Whether it is mobile, telecom or Unicom, their networks are very mature. Under normal circumstances, there will be no noise in mobile phone calls. If frequent calls are noisy, it is likely that hackers are listening to your calls.

Third, mobile phone calls hang up abnormally.

If our ears or face accidentally touch the "on-hook button", it is normal to interrupt the call, but if you are sure that you have not touched the on-hook button, or this problem often occurs, then be careful, because your call may be monitored!

Fourth, the phone is abnormally stuck when answering the phone.

Normal mobile phones will not get stuck when answering the phone. If you often get stuck, you should pay attention, because eavesdropping software usually takes up a lot of mobile phone memory during access, which leads to the slow operation of the mobile phone and the phenomenon of stuck.

Fifth, the phone is automatically connected.

Of course, you need to rule out the situation that you automatically connect the Bluetooth headset. If not, the mobile phone automatically answers the phone, then most of the devices monitored by the other party will automatically run, resulting in the automatic connection of the mobile phone.

Six, the third party's call

Your mobile phone card suddenly opened a third-party call. This function means that during a call, if you dial in an external mobile phone number, the mobile phone can remain connected without being detected, and then the third party phone can clearly hear your conversation with others.

7. Strange numbers in the address book.

Some incoming calls will be inexplicably stored in our address book, or there are some strangers in your mobile phone address book. These numbers are probably for the convenience of monitoring, so when we see such strange calls, we must delete them in time.

Eight, the use of mobile phone tariff packages or traffic inexplicably increased.

Mobile phone monitoring may carry monitoring software through internal unknown software, which takes up a lot of memory and consumes a lot of traffic. Once these softwares are used in mobile phone software, they will consume a lot of traffic and even phone bills. If the mobile phone inexplicably generates fees and traffic, pay attention to whether it is monitored.

Nine, mobile phones often appear black screen phenomenon.

In the process of using mobile phones, non-human factors frequently appear black screen phenomenon, which should be paid attention to. Monitoring the user's mobile phone will operate the mobile phone hardware and other functions, and the black screen phenomenon is conducive to covering up the monitoring behavior.

X. An unknown APP appears in the mobile phone.

If one day you find an inexplicable app in your mobile phone, you must be careful. These unknown apps have their own monitoring function, and your mobile phone may be monitored.

How should I avoid being watched? The following nine points, I hope to be useful to everyone:

First, resolutely do not install rogue software and unknown software.

Second, don't use an unknown charger outside!

Third, you can set the corresponding permissions for the software, such as microphone, call, SMS, location and so on.

Fourth, don't click on unfamiliar links.

Five, do not browse the web page automatically pop up the page.

Sixth, after the mobile phone is broken, you must go to a regular repair shop for repair.

7. Don't lend your mobile phone to others. If you must borrow it, you'd better use it in person, that is, return it immediately.

Eight, turn off the Bluetooth function when going out, and don't connect unknown WiFi.

Nine, buy a mobile phone to a regular mobile phone shop, pay attention to some mobile phones given by businesses or others.
