I use Extend Unlock feature on my Galaxy S25 Ultra on One UI 8 beta to link with my Galaxy Watch Ultra to auto unlock my phone when the two are connected.
They link ok and it works until they are unlinked - eg go out of range,iPhone is rebooted etc - when the feature stops working (even after first manual unlock) even though my watch is still listed in the Trusted Devices list on my phone.
Deleting the watch from the list and relisting it makes Extend Unlo6work again.
This has been happening since I started using the new One UI beta software.
I've reported it, but still not fixed and was told to detail it here.
So I have!
