Check notification permissions, Focus or Do Not Disturb, and background app access first. Then compare one affected app with others. A paired phone and watch may send an alert to only one screen. Follow the matching model notes before resetting pairing or deleting app data.

Model-specific
What is true of this model and not of its siblings
- Samsung Galaxy S26+ notifications are delayed or missing
- Delayed or missing notifications are the S26+ complaint with the most impressions here, and the reports point at One UI 8.5 more than at any one app. Owners describe notifications that arrive minutes late and affect every app, and one thread on XDA is titled exactly that. Sammy Fans reported a notification panel glitch that remained even as the update reached its final stage. The fixes that appear in the S26+ guides are modest and ordered: restart, check Do not disturb and any Mode that is active, check the per-app notification switch, and clear the cache of the system apps that draw the notification shade, Android System Intelligence and One UI Home. If every app is late and the cache clear does nothing, the cause is the update and the answer is the next patch.
- What the reports describe
- Delays of minutes on every app after One UI 8.5, with no firm cause or universal fix in the threads.
- The panel glitch
- A remaining One UI 8.5 notification panel glitch was reported shortly before the update reached its final stage.
Stop boundary
When this stops being a self-service repair
- !If every app is late on the newest patch, send a Samsung Members error report with timestamps
- !If one app only, contact its developer
- !If the notification panel itself glitches, note the exact behavior and screenshot it
