How can I remove...

[Vitorsun]

I bought this watch 5 and I would like to know how to remove this top icon

[_nok_]

Looks like "disconnected to phone" icon.

Have you tried looking at your watch setting > then connections and scroll down and check if there's an option for disconnection alerts. Try disabling it there.

Hello @GenD21

The only way to get rid of the top icon is by connecting it to a phone.

Kind regards,
