Default notification sound and touch can be changed
When you install the new beta of iOS 17.2, you’ll see a new option under Sound & Haptics that allows you to choose the sound to be used for all incoming notifications, except for message, email, and calendar alerts, which already have customization options; Default Alerts. When you tap on the default alerts, you will be greeted with dozens of ready-made tones and tone options that you downloaded later. If you wish, you can also change the touch feedback by entering Touches in this menu.
So far, Apple hasn’t provided an option to set the default notification sound. So it’s a notable update for those looking for a different sound.
