Newbie here so pardon any stupid questions... I am wondering what happens and what should or can be done about apps that are on a phone but have been replaced or are not needed. For instance, my phone has an app entitled "Internet"--obviously, apparently, a clunky browser of some sort. I installed Chrome. Much, much better. So can I remove/delete the "Internet" app? Similarly I was looking at "SwiftKey" simply because I have blunt fingers. But what happens to my regular default keyboard if I do? How can I get rid of it or disable it? I inherited this phone and it has apps and widgets that I will probably never use--such as half a dozen clocks, several stockmarket interfaces, etc. Can I get rid of them? Will it lighten the load? Free up some memory, etc?
