Hi.
It does sound like hardware issues.
If this was my situation I'd visit a Samsung service location or if ones not local then contact Samsung Customer Support directly.
If the watch was supplied by someone other than Samsung then you may need to approach them.
Daily Driver > Samsung Galaxy s²⁴ Ultra 512Gb ~ Titanium Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
