Got the phone less than 2 months ago. It doesn't connect correctly to wifi. Even on data plan, the connection is bad. Home wifi is fine it connects to other Galaxy notes phones, ps5 etc.... But mine nope. Has anyone find a real fix yet? It has gotten bad since the last update.
for wi-fi, try to restart your router
for mobile data, try to contact your carrier
or submit an error report on members app > + button > error report, it could be a software issue since the issue started happening after the last update
