I Recently bought the Philips 42in 3500 Series (42PFL3507H) Marketed as a Smart TV!

Now either I am doing something wrong, or I don't know... but it seems That this TV is a Smart TV however all I can use is the Youtube App... even the interface feels old...

I want the ability to check news browse the internet use social media on my New TV. Is it possible?
