Should I buy iPhone 5S 15GB instead of OnePlus Two?

I did used android for more than 2 years(Galaxy S3) and it was a really good experience.
But it died later and after months without a beast phone in my pocket now I'm using a Moto E. And it's good atleast for my use. All I want is Music, some small games whatsapp, Good camera and that's I've found that I don't need much space now.

But on the other I only have the budget for OnePlus Two which is another Beast or "FLAGSHIP KILLER" but I'm bored with android now.

So I can wait for 2 months and can buy iPhone.
So please let me know some suggestions

NEEDS:
1.Whatsapp
2. Good Camera
3.Music
4.Small Games
5. Maybe movies sometimes.

PROBLEM:
LOW BUDGET

Forgot iPhone passcode? (Not lock screen passcode but security passcode)?

I know the lock screen passcode to get to the home screen etc. However I let my friend put a security passcode which is the passcode used to hide or show certain apps and also to reset factory settings etc. On an iPhone.

BUT HE FORGOT IT!

So how do I reset this passcode or bypass it?

I let him do the passcode because he was supposed to be my safekeeper of the passcode as I removed Safari on my own to put in a browser that had web filters on it so that I couldn't access Safari.

How Sync iPhone music to MacBook Air?

I have had both the phone and mac for a few months now, and I've just bought a few songs on the iPhone through iTunes and now I want the songs on the MacBook. They haven't shown up in my computer with the little cloud with the arrow ( like on the iPhones when you download a song on another device). Do I have to sync my iPhone with my laptop or is there a different way?

Husband's impulsive spending

My husband just bought a $200 used and broken robot toy and another $74 robot toy on the same day using his credit card. He's been buying stuff like clothes, sneakers, iPhone, gadgets, whatever stuff he doesn't really need. Who knows what else he bought since he's been hiding these from me. He wants to eat out a lot, and buys things not on budget. We're supposed to save up for future plans but we can't move forward. I can't do it by myself and pay for everything. We talked about this before, that we need to save up, but it seems like it didn't really sink in him. How would I deal with his impulsive spending? TIA.

IPhone 6, Note 4, S6, or Moto G?

IPhone 6, Note 4, S6, or Moto G?

Added (1). I had a very bad experience with the Tmobile Lg G3 variant so I'm leaning towards Apple, eventhough I like android better.

Has anyone had luck with getting deleted messages back?

I deleted text messages from my iphone recently from a few weeks ago and its important to me that i get them back.
i've read online when you plug your phone in your computer it scans it and you're able to get text messages back or through itunes.
i would rather not go to apple store if i don't have to.

Won't let me FaceTime somebody?

My friend and I are trying to FaceTime each other, he has an iPod touch and I have an iPhone 5s. We added each other to our contacts but for some reason, my name in his contact doesn't show the FaceTime option, only regular calling. And his name in my contacts does give the FaceTime option, however when I try to use it, it just says "____ is unavailable to facetime"
What do we do to fix this? It seems that we ve tried everything.
