My iPhone 6s is glitching like crazy?

Since last night, my iPhone continues to constantly glitch with a purple and pink screen, and the outline of the screen is a bluish pink. Glitching lines keep showing up on my screen and the entire screen keeps flickering. My phone can't stay on unless it's plugged in, and if it's unplugged (even though it's nowhere near having low enough power to die) it goes to this black and blood red screen with the Apple logo. And when I'm on one thing And move onto the next, there's still an outline of what I was on, a faded version of it and the keyboard is lagging.

Got that from china cuz u cheap

  • Why does my iPhone 5 battery draining like crazy? It was on 80% like 20 mins ago and now it's already on 71%. I have all my apps closed. I'm using 3G because it's important. Location services are off. Bluetooth is off. I've tried everything and nothing's improving.
  • Ways I can make my iPhone stop glitching? Lately my phone has been glitching and going slowly when you try to exit out of a screen. It sometimes takes a minute and then spazzes. Then when I try to switch pages, it is slow also and ends up getting stuck on a page when I want to change it. It is only about a year old. How can I make it stop spazzing?
  • New iphone 5 keeps lagging and glitching? I got an iPhone 5 16gb just less than one month ago and it is very slow and it glitches a lot. Sometimes it even freezes all together an I have to turn it off and on. I bought it at the source in the beginning of November. What should I do? I don't want to reset it all as I have stuff on here that I can't lose.
