How do smartphones sing ringtones?

Download it to your mobile phone from the ringtone website first.

Second, there is a USB cable in the mobile phone accessories. Connect to the computer with USB.

Mode 3: The mobile phone has a TF card, and a TF card reader is purchased. TF card+card reader =u disk, and then connect the computer with u disk.

Fourth, the computer must be able to access the Internet. For example, in the 360 network disk, the downloaded ringtone file is set to share, and the mobile phone logs in-downloads. Or send the [Share Link] short message to the mobile phone (360 network disk can send letters for free). When the mobile phone opens the short message, it can be downloaded to the mobile phone through [Extract Link] and [Open/Download]. (A mobile phone must first establish a local wireless network connection)

Mode 5: Bluetooth transmission mode. (omitted)

Mode 6: Infrared transmission mode. (omitted)

If you are young, you can [search online] a satisfactory [download] and then [handle] it yourself, and then send it to your mobile phone and finally set it as a ringtone.

Ringtone websites usually hide the download address, so install a sniffer software on your computer before downloading. There are many ways to reprocess downloaded ringtones online, so go and search for them yourself.

If you really don't know anything, you still have to spend money to download it from the website. I just can't enjoy this process.
