2. In fact, it's not difficult. When we use mobile phones everyday, there will be some background applications, which will be "killed" after restart. However, if the mobile phone is hacked and rebooted, it will enter a high load state again, and the system running memory will be used up quickly. Therefore, if the mobile phone is stuck, hot or dead for no reason, it may be g

Look at the mobile phone shell: when opening a new machine, you will obviously notice that there are films on the "key parts" of the machine for key protection, such as the inner screen, outer screen, camera and so on. As long as these parts are touched, they will leave fingerprints. In addition, st and traces of use are also unavoidable in renovating the machine. The gap between the upper and lower shells of the machine, the gap around the keyboard, and the charger slot are all places where it is easy to "hide dirt". The rotating shaft of the clamshell machine will also leave traces of use, which should also be paid special attention to. Check whether the front and back parts of the machine shell are easy to close loosely and leave a large seam. The identification method is to use your fingernail to try whether it can be inserted into the seams of the upper and lower covers of the mobile phone. If it can be inserted, it is used
2. Check the scratches on the chip of the mobile phone battery. If there are many scratches, it is obvious that it has been used. In addition, if there are scratches on the plug of the matching charger and headset, the mobile phone is probably not brand new

9. Slowly approaching and penetrating into our life, however, how much do you know about it? Do you know what a mobile phone virus is? Do you know the harm of mobile phone virus? Do you know how to prevent and remove mobile phone virus? If you don't know the above questions, please read this special report about mobile phone virus. 1、 The concept of mobile phone virus mobile phone virus is also a computer program, and other computer viruses (programs) as infectious, destructive. Mobile phone virus can be spread by sending SMS, MMS, e-mail, browsing websites, downloading ringtones, etc. Mobile phone viruses may cause users' mobile phones to crash, shut down, delete data, send out spam, make calls, and even damage SIM cards, chips and other hardware. 2、 The earliest mobile phone virus in the history of mobile phone virus appeared in 2000. At that time, mobile phone company Movistar received a large number of harassment messages called "timofonica" sent by computers. The virus sent spam messages such as dirty words to users in the system through the mobile system of Telefonica, a Spanish Telecom Company. In fact, the virus can only be counted as a SMS bomb at most. The real mobile phone virus didn't appear until June 2004, that is, the "cabir" worm, which is copied through Nokia Series 60 mobile phones, and then constantly looking for mobile phones with Bluetooth. After that, mobile phone viruses began to spread. So, what are the mobile phone viruses that appeared later? What harm do they all have? 3、 Working principle of mobile phone virus software in mobile phone, embedded operating system (operating system solidified in chip, generally written by Java, C + + and other languages), is equivalent to a small intelligent processor, so it will be attacked by virus. Moreover, SMS is not just a simple text, including mobile phone ringtones, pictures and other information, which need to be explained by the operating system of the mobile phone, and then displayed to the mobile phone users. The mobile phone virus invades the mobile phone by the vulnerability of the software system. Mobile phone virus to spread and run, the necessary condition is that the mobile service provider to provide data transmission function, and the mobile phone needs to support Java and other advanced program writing function. Now many mobile phones with internet access and download functions may be invaded by mobile virus. 4、 Harm of mobile phone virus 1. User information is stolen.

The most common harm of mobile phone virus is to destroy the software and hardware of mobile phone, resulting in the mobile phone can not work normally. 4. Cause the communication network paralysis. If the virus infects the mobile phone, force the mobile phone to constantly send spam information to the communication network, it will inevitably lead to the communication network information congestion. This junk information will eventually paralyze the local mobile communication network. 5、 The types of mobile phone viruses can be divided into four categories according to the virus forms: 1. The viruses "Kabir" and "Lasco. A" transmitted through Bluetooth devices without red transmission. Little knowledge: "cabir" is a kind of network worm virus, which can infect mobile phones running "Symbian" operating system. After the mobile phone is infected with the virus, it will scan the neighboring mobile phones with vulnerabilities by using the Bluetooth wireless function. After finding the vulnerable mobile phone, the virus will itself and send it to the mobile phone. Lasco. A virus, like worm virus, spreads to other mobile phones via Bluetooth wireless. When users click on the virus file, the virus is activated immediately. 2. Aiming at the mobile phone virus "mosquito Trojan horse" of mobile communication companies. Little knowledge: the virus is hidden in the cracked version of the mobile game "fight mosquito". Although the virus will not steal or destroy user information, it will automatically dial and send a large number of text messages to the number located in the United Kingdom, resulting in a sharp increase in user information costs. 3. For mobile phone bug virus "mobile hackers". Tips: Mobile hackers (hack. Mobile. Smsdos) virus spread through SMS with virus program, as long as the user tempgo2
