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.
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.
I got my s25u today and am having the same issue. I can see the notification pop on my screen then it disappears completely. No sound, vibration or ability to see that it came thru unless I witnessed it.
