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.

I got my S25 ultra yesterday and after doing a clean install, no smart switch, I noticed I was not  getting any gmail notifications. After trying various things with power settings I found  this thread. Have tried everything in here and I seem to now be at the stage that I will get the first notification and then no further ones. I have ticked the option for it to notify for all emails, but still not working. One odd thing I found though, is when its on a charger, it all works perfectly. Sent loads of emails and not one failure. Once I take it of the charger, one email notification and then nothing until I unlock the phone. I have a watch & connected, but that seems to only get the same notifications as the phone.

OK

I had the exact same problem and I think I found a solution. 

First I tried to clen cache in recovery. But it didn't help. 

Changing the dns to a different one and go back  to "private dns - off"

It worked. From now on, I can enable push notifications, for example, in my banking app.

Interesting. I checked mine, it was on as well (the automatic setting). Turned it off, and we shall see.

I wonder what DNS Samsung was using that was "private"? Cause I'd bet money its not really private....

thats nonsense, i have been using private DNS for 2 years on my old S23, and configured the same address as before, never had issues on my S23

S25 is half baked, if not fixed before return window i'm sending it back

[Squeaky369]

Are you using a private DNS that YOU set, or one that Samsung chose? Cause I will use Google or Cloudfare, but manually set the IPs. But I didn't check this setting when I set the S25 up.

[mrbart]

its my own DNS i setup

I can't believe this!

The "fix" worked indeed! How could you even think of this as a possible solution? 🙂

I also used dns on my Note10 plus. 

nextdns

And when moving it, it copied the configuration. 

After disabling private dns I was able to trigger push notifications.

After switch DNS completely off I could set up apps like ING.NL - Bankieren. It didn't work before. Now it works with and without dns.

Holy **bleep** - removing my own private dns allowed me to enable push notifications on several third party apps. Interesting bug! I do hope Samsung fixes this quickly.

Excuse me, I think I had them all enabled, but they were just not coming through. 

What do you mean by “enabling” push notifications?
