This issue involves personal habits and needs, and the specific on or off needs to be decided according to different circumstances.
If you need to quickly transfer files between devices, such as when sharing photos, music, or other files with friends, turning on mutual transfer can be convenient. At this time, just put the phone close to other devices, you can quickly complete the transmission, without the need to go through the network or other cumbersome operations. This convenience greatly improves the user experience and saves time and effort.
However, the cross-transmission function also has some security risks. Turning on the mutual transmission function could leave the phone vulnerable, as unauthorized devices could also gain access to the user's phone through the mutual transmission function. This means that there is a certain risk, such as the spread of malware or viruses, that could cause the user's personal information to be leaked or the phone's system to be compromised. Considering security concerns, turning off the cross-transmission function can effectively avoid these potential risks.
In addition, turning on the mutual transmission function usually requires the use of wireless transmission technology such as Bluetooth or NFC, which consumes the battery power of the phone. Especially when using the mutual transfer function for a long time, the battery life may be greatly shortened and it needs to be charged more frequently. For those who often need to use the phone for a long time, turning off the mutual transfer function can extend the battery life of the phone and reduce the number of unnecessary charges.
Therefore, if you often need to transfer files between different devices, and are willing to take some security risks and battery consumption, you can turn on the cross-transfer function. If you are concerned about safety issues, or want to save battery life, you can choose to turn off the cross-transfer function.
