Will the mobile phone be mined after it is turned off
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
it is possible that hackers steal all the information before using mobile phones to "mine" cryptocurrency. People will not only encounter problems such as cell phone stuck, fever and even crash, but also other financial losses
moreover, it is worth noting that some mobile mining apps, in the name of "mining", allow users to invest money and continue to develop offline
The mobile phone can be turned off to prevent the mobile phone from being detected by the metal detector
[reason]
metal detector mainly uses the principle of electromagnetic inction, and uses the coil with alternating current to proce rapidly changing magnetic field. This magnetic field can ince eddy current inside a metal object. The eddy current will proce a magnetic field, which will affect the original magnetic field and cause the detector to sound
the accuracy and reliability of metal detector depend on the frequency stability of electromagnetic transmitter, and the working frequency from 80 to 800 kHz is generally used. The lower the working frequency, the better the detection performance of iron; The higher the working frequency, the better the detection performance of high carbon steel. The sensitivity of the detector decreases with the increase of the detection range, and the magnitude of the inced signal depends on the size of the metal particles and the conctivity
in short, the metal detector adopts the principle of electromagnetic inction, the electromagnetic field generated by the detector generates inced current on the mobile phone, and the inced current will generate magnetic field reaction on the detector, so that the detector can sense the mobile phone. There is metal in the mobile phone, whether it is turned off or not, it can be explored
[another]
after power off, the signal detector can't detect the mobile phone< br />
in this way, there will be no more leaks
if you don't use a mobile phone, others won't know you use it
all apps in the mobile phone can't be connected to the Internet, so the privacy in the mobile phone won't be disclosed.
