Notification Lock screen

[Boggdan]

Team,

I'm experiencing delayed notifications on my Samsung S25 Ultra (running UI 7.0) only when the device is locked. Notifications arrive as expected once unlocked. All relevant settings appear to be correctly configured.

Many thanks

Hi, I am facing same issue of delayed notification on S25 ultra. Once I unlock screen all notifications comes at once. Please if anyone can guide. Thank you

Hi! Exact same issue here, did you manage to fix it?

There is a long discussion of this on the US forums. Only solution I found was to use "adb shell dumpsys deviceidle disable" after downloading android platform tools.

USB debugging needs to be enabled for that.

Is the  app you are using  called Android Platform Tools? 

[Denobulan]

Yes. Basically I downloaded the Android Platform Tools and saved it to the c:\adb and extracted in there. Then the process is

• Connect phone by USB and accept the connection (you need to have USB debugging enabled)
• Open Command Prompt
• cd to where you extracted plaform tools
• type "adb shell dumpsys deviceidle disable" and hit enter
• Should see two responses - "Deep idle mode disabled" and "light idle mode disabled"
• type "adb kill-server" and hit enter --- this will let you safely disconnect the phone
• Disconnect the phone and enjoy

Caveat - this needs to be done after each reboot.

This is what I've been  doing for the past month and all works well.

However, I received the latest OneUI/A15 patch from Samsung on Monday and notifications are working waaaay better than before so I haven't had to use the adb command in the last couple of days.
