Alvinantoz , via OnePlus 7 Pro , Jul 25, 2020 : My OnePlus 7 pro screen goes off while playing audio files send via whatsapp. WhatsApp has introduced a new feature while playing audio if we place the phone to ear the voice play through earpiece speaker. But in my case my phones screen goes off even without placing the phone in ear. I also made sure the light sensor is not blocked while playing the audio from WhatsApp evnthough the screen goes off and the audio file started playing from the top earpiece speaker. This problem is faced only when using WhatsApp otherwise the sensor works fine when making calls or playing audio msgs from Instagram etc.
