Stupid question about IOS 11

[Perovic95]

Hello, 
I just got iPhone for the 1st time and I have one issue I guess I am too stupid to figure out.

 

How do you go step back? You know that thing you have on android where you press it and it's like one page back on browsers.
For example, let's say I am using Tinder and I go into someone's profile, I cannot take a step back into messages, no I have to turn Tinder off and on again.

 

And while on the subject, how can I use that option that my MacBook connects to iPhone cellular automatically when wifi is lost? It is grayed out.

And the 3rd question is about camera app, where can I find camera settings and can I shoot a portrait (thing when they blur the background)?

 

Hardware: iPhone 6s, MacBook pro retina 2012, Sofware: Newest IOS and Mac OS. 

 

Thanks

On safari you have to swipe up for a bar at the bottom of your screen to show up. Then press the “<“ button. You can also slowly swipe from the absolute left of the screen to the right.

 

I don’t own a macbook so I can’t help with that.
