Welcome to the forums. You can try to press and hold the power button to simulate a battery pull. Perhaps that might correct it enough to fix.

That's a tricky one. You can try this.

In the lock screen swipe down from the top twice. Now the slider is there but you don't see it! It's about two fingers down the edge. Tap on that imaginary line until you've got your brightness back. Having another phone at your side could help.

Good luck.

Just to give you an idea.
