Each has his own merits. The Flash runs very fast. Fast transmission of eggplant: mobile phones can transmit to each other, computers and mobile phones can only transmit to each other under the same WIFI, and like fast teeth, a PC-side software should be installed on the computer. Interestingly, there is also an eggplant replacement function, that is, if you change your new mobile phone, you can transfer all the contacts, text messages and call records in the old mobile phone to the new mobile phone, which requires ROOT permission. I haven't tested this function.

Flash transmission: there is definitely no problem with the mutual transmission between mobile phones. The mutual transmission between mobile phone and computer also depends on the same WIFI network, but the flash transmission does not need to install PC-side software on the computer. Just open the browser and enter the address 192. 168 * * to fully manage the files on the mobile phone, including deleting and pasting. The file management interface is very similar to the computer resource manager, so you can get started quickly.
