Why isn't my iPhone playing videos?

So I have an iPhone 5s. It's about a year old now, and all of the sudden it starts to crap out on me. This started yesterday, where it wasn't playing video content via Internet. It wasn't playing YouTube, Instagram, or tumblr videos. It even wasn't playing soundcloud audio. I don't know what else to do. I've tried deleting and re installing the apps, and disconnecting and reconnecting to the Internet, but none of that has worked. Any tips?

Added (1). I've tried numerous times plugging it into the computer but get nothing. I've also tried putting it in DFU mode… I don't have the money to take it in the shop right now so if anyone knows how to fix this issue, please lemme know…

Does my iPhone 6S have water damage? Is there any other water damage sensors in the phone?

I got my iPhone 6S about a month ago and I love it. The phone is working perfectly, but the thing is last year I had an iPhone 5S and it got wet and the sensor inside went off. Apple then wouldn t replace it under the 1 year warranty. Well my iPhone 6s hasn't been dunked or anything but I took a shower and came out and the phone was covered in moisture:/ I know not smart. I also work out with the phone so sometimes it's sweaty. Do you think I set the moisture sensors off? I checked the one with the SIM card and it didn't go off. The phone works fine but do you think the inside ones show water damage?

My iphone 5s screen just went completely black?

I was just sending a text and my screen went black. After a moment it came back on but the phone was freezing/acting up so I pressed the lock button, but now it won't unlock. I know the phone is still on because it makes the sound when I plug it in, and vibrates/makes sound when I get a text. But when I press the lock button nothing happens (the home button is broken and I use assistive touch so I can't try the home/lock reset thing). I plugged it into itunes and that s acting normal so I know the screen is the only problem. What should I do? IIm so annoyed.

Added (1). I can't hold the lock and home button. Like I said the home button is broken
