I was having the same problem. My son and I got S8 phones at the same time, his worked mom didn't. I tested the sensor on my phone and it worked great. After reading more, I realized it might be my new phone case so I took it off. Guess what, phone works without the case. So, what's the problem, I was using a magnetic wallet case. The magnet was interfering with proper functioning. I'm bummed to because I really like this case.
