What is the fastest way to transfer files between mobile phones?

The data transmission speed between two mobile phones is the fastest under the 5GHz WiFi network, but the 5GHz network is unstable, so it is not practical to have obvious effect unless you are in the same room with the router.

It is convenient to transmit data through wireless hotspots and 2.4GHz networks, but it is slow and takes the longest time.

With the help of traditional USB flash drive and OTG adapter, the fast transmission of large files between mobile phones can be realized without using the network.

Some mobile phone software is specially designed to solve the problem of short-distance transmission. Using these softwares, mobile phones can establish a hotspot, and when other mobile phones join this hotspot, they can transfer large files between two mobile phones. Using third-party software to establish wireless hotspots to transmit large files does not require traffic or WiFi network. As long as the two mobile phones are close enough, large files can be copied.

However, using hotspots as a transmission method has a disadvantage: in order to avoid consuming mobile phone traffic during transmission, such software will generally prompt users to turn off the data traffic function of mobile phones, so that the two mobile phones are basically disconnected during transmission.

However, if it is in the environment of WiFi wireless network, two mobile phones can use the existing wireless network to transmit files, and at the same time, they can keep the connection between the mobile phones and the Internet. In this way, users can send and receive files while handling other things with their mobile phones. Transferring files through WiFi wireless network is almost the same as using hotspots. However, if the router supports the 5GHz band, two mobile phones can be in the 5GHz band at the same time, and the file transfer speed is much faster than the ordinary 2.4GHz band.

However, there is a problem with the WiFi wireless network in the 5GHz band, that is, the ability to penetrate the wall is weak, and the network speed often becomes different every other room. In most cases, we use 2.4GH network. Therefore, it is very fast to transfer files in the 5GHz band WiFi environment, but it is not practical.

U disk is still the most convenient way to copy files at present. A qualified USB 3.0 USB flash drive can read at 180MB/ s and write at 60MB/ s, which is much faster than wireless network. Most Android flagships in the market support OTG function, that is, reading USB devices through the charging interface, and simply buying a USB-to-OTG adapter can make the mobile phone read and write the U disk normally.
