Samsung Notes not working: safe fixes in order

Quick answer: Restart the phone, update Samsung Notes and the phone's software, then clear the app's cache. Before you clear data or reinstall, make sure your notes are synced to Samsung Cloud, because those two steps can delete notes stored only on the phone.

Protect your notes first

Samsung Notes can keep notes only on the phone. Some fixes for a broken app (clearing its data, uninstalling it) can wipe those notes. If the app still opens, go to Samsung Notes settings and turn on Sync with Samsung Cloud, then wait for the sync to finish before trying anything below the cache step. If the app won't open at all, stop at the cache step and contact Samsung support before going further.

The fixes, in order

1Restart the phone

Press and hold the Side button and Volume down, then tap Restart. A restart clears a stuck app process and fixes most one-off crashes.

2Check your connection if notes won't sync

Turn Wi-Fi or mobile data off for a couple of minutes, then back on, and try again. Samsung recommends switching to a different network if syncing still fails.

3Update Samsung Notes and One UI

Open Galaxy Store, search for Samsung Notes and tap Update if it's offered. Then open Settings, tap Software update and install any update. Samsung says a compatible sync version will be released for the One UI 9 issue. Keep checking for updates; the support notice does not establish that the version currently installed on your phone resolves it.

4Clear the app's cache

Open Settings, then Apps, find Samsung Notes, tap Storage, then Clear cache. This removes temporary files only. Your notes are not touched.

5Free up storage

Open Settings, then Device care, then Storage. If the phone is nearly full, delete large videos or unused apps. Apps crash more when there's little free space.

6Clear data only if your notes are backed up

Only after your notes are synced to Samsung Cloud: Settings, then Apps, then Samsung Notes, then Storage, then Clear data. This resets the app. Open it again, sign in to your Samsung account and let the notes sync back down.

7Factory reset as a last resort

If several apps keep crashing, not just Notes, back up the phone and use Settings, then General management, then Reset, then Factory data reset. This erases everything on the phone.

If notes won't sync after One UI 9

Samsung says One UI 9 changed the format of notes that use the dotted pen, masking tape or images inside tables, so those notes can't sync with older versions of the app. Keep updating Samsung Notes on every device until a compatible version arrives, and contact Samsung support through the Samsung Members app if it still won't sync.

Which phones this applies to

Menu names are from Samsung Galaxy phones on One UI 6 and later. Older versions may say Applications instead of Apps.
