Downloading MP4 files, like ringtones, on an iPhone can be tricky due to iOS restrictions. One way around this is to use a video editing app like Kinemaster to edit your ringtone, then save it in a compatible format. Once edited, you can use an app like GarageBand to set the file as a ringtone. It’s a bit of a workaround, but apps like Kinemaster Pro APK Latest Version 2024 make it easy to customize and export exactly what you need just like for photo editing.
