New S25 Ultra - Notifications not working

[Squeaky369]

Howdy!

Received my new S25 Ultra yesterday, set it up via SmartSwitch. Everything transferred correctly but none of my notifications are working. 

Zero.

I have gone though forum postings that other people have posted looking for solutions and most of those has been DND or a routine turned on blocking notifications. 

Things I've checked:

• Do Not Disturb is TURNED OFF.
• No Modes or Routines are running (there aren't any setup).
• Sound is on.
• Vibrate is on.
• No icons or app badges show up on the top.
• The apps that I am testing with I have confirmed that notifications are turned on.
• All the options are selected for the notification options (Lock Screen, App icon badge, Notification pop-up).
• This happens if the phone is sleeping or awake.
• My old phone is still using Wi-Fi and notifications work fine on that one (other than messages and phone cause that's tied to the SIM). Turning off the old phone and waiting a few minutes and trying on the new phone, same thing happens.
• If I open the offending app, I can see the unread messages.

Other than wiping the phone, skipping the SmartSwitch and starting from scratch, I am not sure how to move forward.

Thanks.

Hi Squeaky369, Welcome to the Community!

Did you check Notification Categories? Check out this thread: https://us.community.samsung.com/t5/Galaxy-S24/Notification-category/m-p/2948508

It's turned on.

Are you connected to Wi-Fi on the S25? Any issues using a web browser, or placing /receiving calls?

[Squeaky369]

I was connected to WiFi for a little bit while testing and I've also tried on cellular. I can place calls, but as soon as someone tries to call me, the phone doesn't light up or make a sound. Then when I unlock, and go to the phone app, I see the missed call.

Web browser works fine.

Have you updated your service provider with the new IMEI number? It could cause a delay in services, and possibly affect the notifications.

[Squeaky369]

Yes; IMEI has been updating with my service provider.

This is also a Unlocked phone directly from Samsung. No bloatware from the provider.

Have you tried resetting "all settings"? Phone Settings>General Management>Reset>Reset all settings? (It should not remove all of your data, but you will have to reconnect to Wi-Fi and reapply any customization settings.)

[Squeaky369]

Just finished the reset settings; unfortunately, that did not resolve it. I am going to go ahead with a full factory reset.

I've been using the same "backup" for quite a few phones now, I wonder if something from a previous restore finally caught up and is causing issues with Android 15.

I'm having the exact same issue and going absolutely mental trying to figure out how to fix it!!
