Hello,
Are these notifications being triggered by the Link to Windows app? This app is usually integrated with Samsung devices, even if you haven't installed it separately from the Play Store.
*Could you please share a screenshot of the notification that is bothering you? This will help me identify which app or service is generating the notification.
Meanwhile, if you have the 'Link to Windows app' pre-installed -
- On your Samsung device, go to Settings > Apps > Link to Windows.
- Uninstall the app from Installed Programs.
If you are not allowed to uninstall this program,
- Select the "Link to Windows app> Then, go to Notifications and set it to disabled.
- Then, select 'Disable app'
If you see 'Link to Windows Service' in the list, tap it, then tap the three dots in the top-right corner, and select 'Uninstall updates'. Click Ok to proceed.
Let me know if you still need more help.
