Hi to all. my lg g6 870ds sound is death. This happen,when i was waching video on you tube,then my phone show no battery and restart alone. When android start, was no sound from the speaker. With headphone is ok. So i dont have notifications sound,only vibration. I recently change the speaker,flash to new stock rom, the prombem is still there. Maybe is the sound ic on the motherboard? Or different thing ? Please help. Thanks in advance. Sorry for my english
