hi, i had the same problem. I realized that when I turned off the phone and turned it on again, the sensors worked (turn off, not restart). Then enter configuration - battery - smart energy saving standby, and remove. I hope it works for you, excuse my English, I'm from Argentina. regards

Hi, I had the same problem, I fixed it like this. turn off the phone, do not restart, turn off, turn on again and go to settings - battery - smart battery saving standby, and remove is option. With that it was solved. Excuse my English, you are from Argentina, greetings
