in Android 10 on LG g7 the low bands are pre dominant, and sounds like the quad dac feature/project (drivers) has been cancelled. So , the built in equalizer is pretty fakked up. I boost up 8k and 16k bands to match the sound like it was before. but it didn't help much.
in Android 8.0 or 9.0 toggling the quad dac button did make a great change. now nothing much. so sad that the lg team got this cruel that they just dropped a feature which is a major thing to people like us. shame on LG.
