Somebody has accessed my secured WPA home network with no password whatsoever?

Two nephews at home… One needed the password, one could access my very own home network with no password whatsoever, and did so on another network. What sorcery is in his iPhone? I'm very worried.

Should I stick with my Note 3 or upgrade to the iPhone 6S (16GB)?

So I've had the Note 3 for about a year and wish to get back on iOS, mostly because of my peers and I really like the iPhone. But practically the Note 3 has a much larger display and a bigger battery capacity. IIm really confused between the two. Is it really an upgrade spec wise or am I losing something in the bargain? It's an exynos version BTW, so there's no 4K recording.

Can a tempered glass screen protector protect iphone 6 from face-first drops?

I already have a Thule Atmos X3 phone case which is made of polycarbonate and silicone, and is supposed to be able to protect the iphone from drops up to 6.6ft and is supposed to be very good at this.
However, it doesn't come with a screen protector.

Could a screen protector prevent my iphone screen from shattering if it falls face-first from a few feet if the screen protector takes the damage and not the actual iphone screen?

How to buy more free storage for my iPhone?

I've ran out of storage on my phone, and I know how to buy more GB s but it's the "per month" thing that confuses me. I only want to buy storage once, I don't want more and more each month? How do I prevent this?
