Missing something we no longer have

I have recently had to get a new phone. I was looking at a post and it changed the colour of the background then asked me about changing colours. It keeps telling me about new things and do I want to install an app.  I keep having to ask how to get out of loops.

Also I can no longer just turn it off, but have to swipe quickly up the screen twice (to avoid doing anything in the process like turning on the torch), to find a small square to start off the powering off. Apparently they are all like that now.

Then I can't swipe to the next page but have to use an arrow and to get rid of a page I have to minimize it first.  Rant over.
