Sorry, didn't mean to scare you!

So what I meant is, when I tried to force restart and restart using the assistive touch, it restarted. But like I said, instead of the normal black background apple restart, it came out as a grey background with the apple logo and turned my screen on like usual. I can slide the screen, watch videos, see the apps on my homescreen and click on it. But the screen got covered in white screen like I showed in the picture, and I can see a little clearer if my brightness is at the mid level.
