I recently bought the Huawei P20 Pro and I'm listening to the volume when listening to music in headphones way too quiet, v. A. Compared to the Samsung Galaxy S7 which I had before. I've already increased the volume in the equalizer menu to 12 decibels, but it's still way too quiet. How can I increase the volume?
To increase the volume further, as far as I know, is not possible.
At least on the developer settings the maximum volume "disable" but if it helps in your case, I can't tell you.
