All of a sudden today, my Samsung Galaxy S4 came up with errors. When trying to access certain web pages (just normal pages), the error was "The page could not be opened. Please try again later." This has happened with several pages. Also, when trying to download an app from the Play Store, it came up with an error 400. I can still access some web pages and my email, navigation system, etc.
Can anyone please help as this is very frustrating.
Many thanks :)
