Nokia please improve the audio quality of headphone jack. The output is flat and loudness is also below average and not at all pleasing to listen. I believe there are already many threads on this topic and yet none of them are addressed. Please listen to your customers for once.
Hi, have you try to tune your sound equalizer via Google Play Music. Try that first, and choose the equalizer or setup a new one and feel the difference. The equakzier setting will work accross the app.
