If you find that your device does not already have a Ringtones or Notifications folder, you’ll simply have to create one first.Next, tap the “Paste” button to wrap things up, which, for Solid Explorer users, is the circular button near the bottom-right corner.From here, open the Ringtones folder if you’re moving a ringtone, or open the Notifications folder if you’re moving a notification sound file. Next, press your device’s back button once to head out to the main SD card or internal storage directory again.From here, long-press the ringtone or notification sound file that you downloaded in Step 1, then tap the “Cut” button at the top of the screen. Once you’ve installed a file browser, open it and head to the Download folder on your internal storage or SD card.Any file browser will do the trick, but I’ll be using an app named Solid Explorer to demonstrate, which is one of the best options out there. For this part, you’ll need a file browser app.
Once you’ve downloaded a sound file, you need to move it to the proper folder on your Android device to use it as your ringtone or notification sound.To get started, you’ll need to either download a ringtone or notification sound directly to your Android device or transfer one from a computer to your device’s internal storage.
