My problem with apps that increase native volume: I'm an audiophile with some expertise in music engineering. I've recently noticed that certain ringtones that rany clearly on my DX sound distored on my DX. I'm talking about the kind of distortion that occurs when the speaker is not powerful enough to handle the sound. This tells me that the GN speaker is not powerful enough to sustain increased volume for certain sounds.
Think about car speakers or speakers in your home that deteriorated over time. It's easy to notice when we had our music way too loud and that caused the speakers to blow. It's harder to notice when we have our music a little too loud for the speaker and the speaker deteriorates prematurely over time, when the average ear is not aware of the problem. Once the speaker has gone downhill, I'm not aware of how to rehabilitate it. That said, I'm steering clear of all apps that increase external speaker volume because by the time you notice the speaker has gone downhill, it's too late.
