Keyboard now not connecting following update

[Zippy1988]

My physical Keyboard now no longer connects to my S9 Ultra following One UI Version 7/Android Version 15, patch 1/4/2025.

Has anyone found this, and found a way to rectify?

Cheers.

2. Reset Keyboard Settings:

Settings → General Management → Samsung Keyboard → Reset to default

Try Clear Software Cache(s), go to:

> Settings → Apps → Tap "⋮" → Show system apps → USBSettings / USBService → Storage → Clear Cache.

Do the same for 'Samsung Keyboard' and 'One UI Home' (via search)

Then reboot
