Last year, Zhigou had exposed the hidden dangers of stealing APP installed in the charging stations provided by many railway stations. This type of charging stand provided two types of connectors: ordinary charging and high-speed charging. This is the next step: Charging process The first choice: Ordinary charging, charging for 10 minutes can not rise by 1%, you consume from the day to night, it is estimated that the phone is also full of dissatisfaction, but also have to be despised behind the line of children's shoes. The 2nd choice: You can choose fast charge, but Android mobile phone must open USB debugging mode, iPhone must click the trust button. Only follow the prompts, you can enjoy the normal charging efficiency (about 5V/1.5A ~ 2A speed it). Just as you and the United States and Britain and the United States looked at the gradual increase in electricity, your phone will be secretly installed several APP, such as XX Guardian, XX games, and so on all kinds of APP. Take a closer look at the instructions on the charging station. In the not-so-obscure place, it has been stated: “When users use high-speed charging services, the device will recommend several hot mobile games or application products to users. Users can Choose to use or uninstall it yourself." That's right, as long as you choose to charge quickly, the default is to install the promotion app on your phone. The reason why, we all understand that in the environment of the train station where the flow of people is very large, every time a user is activated (in the mobile phone installed promotion APP), manufacturers can profit from software manufacturers 1 to 2 yuan. Think about it, when numerous railway stations are using this promotion method, how much money can one day earn? Hey, do you think that as long as you carry your treasure with you, it is safe to use this type of charging point? If you do not close the following settings, you will still face serious security risks. Keep these security options in mind Android phones do not have such a strict management mechanism as the iPhone. You can use the on-line app store to download the app. You can also download the app from your computer and copy it to your phone. You can also download apps from third-party app stores or browsers or other apps. . In addition to the mobile phone's own application store, which can provide a slight degree of security, there are significant security risks in other channels. Close unknown source Therefore, the first thing we need to do is to develop a good habit, which is to download the APP only in the official app store . If the official app store is not included, go to the official website of the app to download it. If you are worried about “accidentally†downloading dangerous apps by mistake, the first thing to do is to enter the phone settings and find and close “unknown sources†in a security-like options screen . As a result, the APP downloaded from the non-official app store will pop up a security warning before installation. If you do not allow it to be installed, you will not be afraid that the app will be stolen in the phone. Prevent browsers from installing automatically Many browsers (including the ones you visit) will pop up XX ads. If you do not pay attention, you will automatically download an app to make it hard for you to guard against. At this point, we can enter the browser's settings interface in advance. Take the UC browser as an example. Inside it provides an option similar to "automatic installation and use". Close it, even if you accidentally download the rogue APP, you are not afraid it will be Automatically installed. Forgot USB debugging mode For Android phones, USB debugging mode is the most dangerous option ! ! ! ! Let's say so, as long as you open the USB debugging mode, the phone is accidentally lost. No matter how many complex passwords (including fingerprints) are set, anyone can connect to the PC and enter a string of code to overcome all your security settings and see your privacy content. Therefore, unless you are playing machine control, do not open this function. Of course, some advanced applications, such as using a USB cable to connect a mobile phone to a PC, enable the USB debugging mode to enable advanced control of the mobile phone to control the PC or PC to control the mobile phone, but these are not worth playing compared to security. In particular, many PC clients, such as the XX Assistant, will prompt you to turn on the USB debugging mode when they are connected to the phone. If you really need to use the functions of these clients, do not forget to turn off this function after you use it. Remember! ! Don't forget to automatically connect Wi-Fi There have been many reports of "fishing Wi-Fi", that is, hackers have established a free Wi-Fi without passwords. If you do not pay attention to access, the other party can remotely read the data in your mobile phone through technical means. It is dangerous not to want to steal a virus Trojan. So, you may wish to enter the wireless settings of your mobile phone and find and close all such options as "Automatic Wi-Fi connection", "Automatically connected signal better Wi-Fi" and so on. Even if it's manually connected to confirm the safety of Wi-Fi is a little tedious, is it better than hitting the gun? Check your app permissions Today's Android phones come with application rights management. They are either hidden in a security manager's APP or integrated into the set security options. Find him, check your third-party app, and turn off similar permissions like making a call, texting, and reading a text message. This is the sad part of the Android system. Even if it is a calculator software, it may default to open read contacts, text messages, call records, send text messages, make calls, read positioning information, open wireless and so on. My TMD just wants to calculate a 1+1 equal to a few, you TMD want so much to see what permissions! ! Nothing, this is the status quo. We can only pay attention to ourselves. Don't scan code easily This is another old-fashioned topic. The two-dimensional codes on street advertisements can be easily swept away. Let’s take the example of the most popular shared bicycle now. There are people on the original QR code on the car and a layer of deceiving QR code that induces you to transfer money. Above, is the basic idea of ​​Android mobile phone safety precautions, do not know if they help you?
