What is the text tool on Windows?

I've used it before. Your can't remember what it's called or where it's at. It allows the user to select various formats of text or symbols that can be copied and pasted elsewhere.
Is there something like this on iPhone I can use?

Will a cracked phone screen damage the phone s usuability?

I just cracked my iPhone 6s today and my heart is crushed. I have not told my parents this yet, and I do not think that they will let me repair it/buy a new phone.

If I just purchase a plastic screen protector and leave my cracked screen be, will it damage my phone itself in any way?
Should I even bother getting it fixed?

What's wrong with my phone?

I have a Samsung Galaxy 5. Lately the Wi-Fi hasn't been working I have frontier which sucks anyway but places in town I can't even connect like Walmart, Lowes or at the university I can't connect. It says it's scanning but the Wi-Fi doesn't come on. I used my high speed date so I can't do anything on LTE for a week. I use to have a one month card then I switch to 6 months. I don't know if it's because I switched many card or what the hells going on it's never done this before. If I known I was gonna have this many problems I would have kept my iPhone. I'm going back to iPhone next time. I have straight talk. What's going on with the Wi-Fi everywhere even at my own house? How can I fix it?
