Hello so I got this samsung watch "gear s3" from my dad and I do reset the watch 2 times first one was for the same problem when I try to open galaxy store in my watch it says "an error has occurred" I really dont know what to do.

I think that store may be outdated due to watch is pretty old itself

so what are you recommending for this?

Personally I think you should upgrade to a better watch
