How to Play music and record snapchat video at the same time on iPhone?

This is my second week with the 6s plus and yesterday when I was recording a video on snapchat, my iPhone automatically paused my music until i was done recording. With my Note 4, I was able to connect my music to my car via bluetooth and the music will still play while i'm recording a video on snapchat. This is my first iPhone so i'm not sure if there's something I have to do?

I keep getting text messages from a random number after I told them to stop?

They don't text me every day, but they've texted me at least 6 times and each time I told them "Stop texting me, you have the WRONG number." Finally I blocked them. They were using an iPhone because the messages were blue, hence iMessage.

Today they texted me again today saying "I'm waiting for you at the Cemetary." I texted them again and the message bubbles were suddenly green, meaning they more than likely have an Android now. I texted them "For the last time, stop texting me, I don't know you." And this time they replied back "But you do know me. I'm your worst nightmare."

I told them to F off and then blocked them--again. Legally, if they keep finding ways to contact me, what can I do? I swear I have no idea who this person is. I've never seen their number before they began texting me.

CSS flexible design confusion?

I can quite happily produce HTML, CSS and or PHP sheets my confusion comes with CSS media queries and flexible design.

Basically with mobile phones in today's day and age having resolutions easily in excess of 1000 pixels how does a CSS media query work which is detecting 800 pixels. As far as I can see CSS media queries are used for changing the layout when something is about to break. Not for actually building mobile friendly sites as I can't aim for 7,8,900 pixels. As my mobile has a resolution that's not so far below my desktop.

M = 1280 X 720
D = 1360 X 768

And if I recall correctly the new iPhone is 1900 plus

How can I be sure that a mobile user is shown a mobile website using flexi design and media queries or any other method.

Any help and advice clearing up my confusion would be appreciated.

Am I blocked on iphone from another person?

Usually when sending an iMessage, it will show up "delivered", then if it doesn't go thru it will turn Green as it was sent as a SMS. But for the past 3 days every text I send DOESN't say delivered, it says nothing, and STAYS blue. So strange. As I tried calling and it rings the average amount of times then goes to VM so I imagine IIm not blocked but can't figure out the text thing. It's staying Blue and doesn't say delivered. IIm not getting a response on the text obviously…
