Can laptops cause brain cancer?

Like if I put my head too close to my laptop while it's running, will it increase the risk of brain cancer? Sometimes I do this to make sure the speakers around it are working properly.

I know how with radiation detectors, they sense zero radiation when they are just a foot away from the laptop screen but it goes up dramatically when it gets any closer.

I know Iphones and cell phones can increase the risk of brain cancer, but what about laptops? Do they emit more or less radiation?

Advice on phone with a good camera?

Sorry, I'm clueless about most forms of technology, including phones. All I've had so far are two iPhones (which I liked) and this Motorola that I have now and I really hate.

I can't afford an iPhone but I want something with a lot of memory and most importantly a really good camera. Also, may sound impossible but I don't want to spend an absolute fortune. I would be happy to get an older model iPhone but I've been told that the updates don't work so the phones are useless (I don't know if this is actually true!)
Any advice on models and makes would be really appreciated, thank you

Should i get an iphone x?

I'm pretty sure i have an upgrade for my verizon plan and i currently have a iphone se with water damage and it has recently has been acting up by not allowing me to call people, and more. Also the screen is kinda hard to see because of the water in it. I was thinking about getting the x because its price was just lowered because of the release of the new iphones.

When will iPhone come?

So I ordered the new iPhone XS max, on 9/25. They said it should be shipped by 10/10 because I guess the stores sold out. Now does that mean it will definitely be shipped around the 10th or anytime between the 25th & 10th? I called them and asked csuse I'm going out of town and I know I need a signature, but I got 2 different answers. Answers being basically what I asked up there^^ has anyone else gone threw this? If so what happened?

Buying an iphone for the camera questions?

I want to get an iphone 6s for the camera alone;I ll be buying it off ebay, used. I want to be able to make long video s and to edit and upload to my computer. I don't want to use it for the phone.

I've been reading that phones are locked (i don't know what that means) I do to a point but does a lock phone mean I can't use it to handle my footage to edit and upload?

I was also wondering if later on i want to use the phone, will a cell phone company unlock my phone because i bought it used off of ebay?

Iphone 6s stuck in headphone mode and i've tried everything

My phone is stuck in headphone so it says i have headphones in even though i don't and i've tried EVERYTHING. I've watched tons of youtube videos and went to tons of websites and i did everything from restarting my phone, to cleaning out the port, and nothing is working. This is so stressful because i can't just go get my phone fixed because i'm a high school student and my parents deal with that stuff and they don't like going to the apple store so they aren't just gonna take me if i ask them they will just tell me "oh well you probably broke it so it's your problem now"

Can someone hack your iPhone through a pdf file?

I had joined Amino, an app where you can go into different communities based on what you liked. I joined a fitness\health community and after I posted something a girl messaged me. We had talked and all was good. She asked if I'd like a book that she had previously bought, but she could send me it through email. It is by someone who is an actual author. She sent it through email and I use safari to open emails. I opened the pdf and then I saved it to the notes iPhones have. Could I get a virus or have malware installed on my iPhone? Could the person sending me this read messages on my phone or hack into my camera or audio? I had the pdf file on my notes for about seven plus months.
