Why is there no longer an earphone port on iPhone 8?

1. Earphone port missing.

2. What is the right side button functions n?

3. Camera use to copy an email or internet image is impossible —

YES, I googled each question, got a tutorial on camera screen shot, but I got zip.

And maybe this is not an Apple Q, but do I not see google history?

Some features are not as simple to use...like sending something to trash...to many steps, screen changes. Annoying.

Why did icloud not send my gmail accounts when transfering to a new iphone? It did send this the last 2 iphones. I finallly got those back, it was not too easy.

I have had 4 iPhones since Nov 2016. Bought an iPhone 8 a few days ago. Thanks, Kat!
