Notifications not working properly

[hantran]

My Galaxy S21 is having issues with system and notification sounds. I don't hear any sounds when pressing keys or locking the screen. In Settings, when I go to select a Notification or System Sound, there’s just silence, though ringtones for calls work fine.

I also noticed that notification and system sounds only play when I’m actively using an app. For instance, on the home screen, I only get vibrations for messages, without any sound. However, if I’m scrolling through TikTok, the notification sounds work as expected. I’m unsure what might be causing this issue.

I’ve tried every possible fix I could find, but the issue still persists, and I’m not sure what’s causing it.

One UI version: 6.1

Android version: 14

Could you please try and do the Phone Diagnostics in me Members App>Support and make sure the phone is operating as it should be. This will rule out any faulty parts of your phone.

Please tell me if you have done this and I'll try something else

Hi, I ran the Diagnostics, and everything appears normal. I also tested the notification and system sounds using earbuds, and they worked perfectly through them.

Hi suggest having a look at this link..

Especially the safe mode option to see if you can isolate the issue

I tried it out, but it still didn't function properly for me. Could it be a hardware problem, especially since my brother may have dropped it, while my other S21 is working perfectly? 

But the notification sound still worked if I have something run in the background tho.
