How to reset focus to default settings?

I've been trying that for the past 3 days, it seems like there's no hope with focus. It just decided not to work all my allowed contact get blocked automatically trying to contact me. I've erase the phone like brand new and it still not fixed. I don't know what else to do it seems like the app doesn't recognize my contacts or I don't

To remove a specific Focus mode, such as Personal, Work, Driving, or Sleep, except for the default Do Not Disturb (DND) mode, you can follow these steps:

1. Open the Settings app on your iPhone.
2. Scroll down and tap on Focus
3. On the Focus screen, you will see the list of available Focus modes, including Personal, Work, Driving, Sleep, and others.
4. Tap on the specific Focus mode you want to remove, such as Personal.
5. Inside the selected Focus mode, scroll to the bottom of the screen.
6. Tap on "Delete This Focus" (or a similar option) at the bottom.
7. Confirm the deletion by tapping on "Delete" in the pop-up message.

By following these steps for each specific Focus mode you want to remove, except for the default Do Not Disturb (DND) mode, you can effectively eliminate those modes from your iPhone's settings.

Whenever needed...

1. On the Focus screen, tap on the "+" icon in the top-right corner to create a new Focus mode.
2. Choose the type of Focus mode you want to create, such as Personal, Work, Driving, etc.
3. Customize the Focus mode settings according to your preferences.

Thanks for the information. So focus won‘t be able to reset to default. Because…. In suggested apps I have superold apps which are off the App Store for years like friends and find my iPhone. Can’t delete those from the list. :-( suggestions for resetting?

You seem to be very knowledgeable about this situation. Can you please provide with a solution to why focus decide not to work like all my allowed contacts get blocked I can only receive calls when I put "everyone" I tried to reset nada, I've reset my phone to brand new still doesn't work.

After “erase all content and settings” you have probably restored from a backup. That will bring back the status before you erased it.

But if you erase only all settings it will reset focus settings?
