Change Alarm Sound
If the default alarm tone on your Realme phone barely wakes you up, swapping in a louder or more personal sound is often the fix. Realme UI keeps alarm sounds separate from your general ringtone and notification tone, so changing those settings elsewhere does nothing for your alarms. Each alarm can use its own built-in tone or a custom song stored on your phone.
Set Custom Notification Sound
If the built-in notification tones on your realme phone all sound the same, none of them may match what you actually want to hear when a message arrives. Realme UI lets you pick your own mp3 file as a notification sound, but it only shows up in the sound picker once it sits in the right place on the device. Storing the file in the wrong folder or using an unsupported format is the most common reason a custom tone never appears in the list.
