Some notifications only come in when the phone is unlocked

[AK-One]

Hello All, 

I received and have set up my Samsung S24 Ultra and love it so far. One issue I am having and can't get to the bottom of it is that my notifications seem to go on hault 'til I unlock the phone. 

I have played around with notifications within each app and also went into battery settings to ensure these notifications are all in order and are not in 'deep sleep' to no avail. I certainly never had any issues like this on my S23 Ultra. I was just wondering if anyone knows what else I can do or check, or is this a 'known' issue and it will be likely addressed in the next software update?

This happened on my S21 Ultra and continues to happen on my S24 Ultra.

It is not all notifications.

You do not realise some are 'waiting' until you unlock your phone and they 'come through' instantly.

I hope OneUI 7 solves it, but it has been a long-standing bug, so I do not hold much hope.

Just upgraded to S25 Ultra with oneUI 7 and can unfortunately confirm that I still have this issue with some apps 😞

Whenever im connected to my home WiFi the phone is almost dead zero notification for everything. the moment i turn on 4g i got a flood of notifications.

i have tried everything solution i could find, disable doze, reset, turn off every battery saving option, keep the apps wake or locked in the background, nothing works.

i even tried different WiFi network same issue. i have multiple Samsung devices all effected as well s24, S21FE, and Tab S8.

my only hope is a batch or next update. this is really annoying and frustrating.

If I found it correct. To turn off dozez you need to do this in bootmode right?

Not really useful l, since you need to reso after each boot.

I'm testing the deep sleep and never auto sleep functions. See if it gets better with that
