I have a Mate 10. ALP-L29 141 (C636). Since ROM 138, media at max volume (15) is played very quiet through the speakers. Sound also sounds slightly distorted. I am not sure if my speakers are faulty or the latest ROM updates broke the sound volume. The speakers never used to be this quiet. Just happened all of a sudden. It's very frustrating. No water, no dirt. I look after my phone well.
Please can someone help? It's got to the point I want to sell the phone now as the sound quality is poor.

I managed to fix the low sound. I used a safety pin to carefully clean the speaker grill holes. I also used a few unclog your speaker apps. The combination fixed my low sound. Sound back to normal now.
