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 also have the same issue as mentioned by some, notifications do not come through while my phone is locked, as soon as I unlock it, I receive all notifications that were missed while the phone was locked. I've tried modifying every notification/battery setting I can think of, with no success.

Note that the notifications appear and make the notification sound upon unlocking so they're not actually being received while locked, not that they're muted, almost like it's a battery saving measure getting in the way.

I've been messing with the settings since yesterday and this is how I solved the problem, because I didn't want to do a full reset.

1.Pusch notifications - They will start working after completely disabling my own dns. Then you can turn dns back on. Everything will continue to work. 

2. Notifications in other apps. - After transferring the app when you first set up your phone. The system took away and permissions for some apps. You have to enter into "App notifications" menu And manually grant them to the apps we care about. With each you can also choose whether you want sound, vibration, visibility on the bars and or the lock screen. So what you like, you choose. 

Then everything works. 

Ps gmail has introduced new notification options, everything only important, only from selected groups, etc. You need to change it in the gmail app. 

I hope this helps others.

Toggling DNS to off fixed this for me.

Gmail notifications take an hour to arrive unless I fingerprint-unlock the screen then it comes through immediately. Gmail notifications are instant only when the phone is being charged and sitting on the desk unused.

1. Private DNS is off.
2. SmartSwitch and Restore from Google Backup was not used, its a fresh start.
3. Removed my Google Workspaces email in Phone Settings > Accounts & Backup > Manage Accounts. Deleted Gmail app cache and data, then re-added the email account inside Gmail.
4. Gmail Battery is set to Unrestricted.

It still suffers from severe notification delays.

I found a solution from a Reddit post. Settings-->Notifications-->Advanced Settings-->Manage Notification categories for each app. Turn that on and you can set different tones for apps. I'm still having issues getting Gmail notifications in general so I don't have an answer for that.

I managed to sort this.

Searched for app under settings and found an option for 'apps that can always use data' and turned that on for gmail. 

Seemed to sort it out.

Thanks. I found it and turned it on. Let's see if that works

This option doesn't exist in A14, so I was hopeful.

Added a bunch of apps, locked my phone and 10 minutes later came back, no notifications.

Unlocked and was blasted with about 20 notifications from a dozen different apps (all ones I added to the list).

Thanks though. Glad it works for you.

Both my wife and I just upgraded to the S25, and also experiencing the problem of notifications from some apps only suddenly appearing when the phone is unlocked. I've confirmed it occurs on a factory fresh phone, so factory reset won't help. I've tried various settings, including adding apps to the list of those to never put to sleep, changing the battery usage of an app to unrestricted, etc. None of these settings fully fixed the issue.

The only thing that DID immediately and fully fix this, was disabling the "doze" mode from an ADB command line after connecting the phone to a computer. Search "doze" mode and how to type "adb shell dumpsys deviceidle disable" from a command line while your phone is hooked up, and it completely solved it. The only problem is this does not stick after a reboot of the phone, and must be done again.

I'm coming from several Galaxy phones in a row, and believe this is a new problem to Android 15. Sounds like the Pixel folks have been dealing with this for a while, and I'm really hoping with more people using the S25 series this issue will get some attention and an actual fix. Supposedly changing an apps battery usage to "unrestricted" is supposed to bypass doze mode, but it definitely does not fix it for certain apps that I found are only fixed through the ADB command line.
