    Hi, @Christine_ASUS

    I would like to report a bug that removes bass from sound. Steps to reproduce it:

    Every time i reboot phone and instantly (as fast as i can) start playing music - sound quality is perfect with full bass. After approximately five seconds of playing music - bass suddenly disappears, sound quality drops. Moreover it behaves the same for both bluetooth and jack audio.

    It seems as if some additional equalizer settings are applied later in boot process - but i don't have any equalizer app installed on my phone.

    Steps i took to resolve the issue:

    1. Reset app settings
    2. Tried safe mode - but there is no music player so doesn't count
    3. Reset to factory settings

    Therefore I would like to record and submit logs from my phone and fill a bug - can you please advise how can i do that.

    Thank you

  • I have encountered with the same problem.

    The headphone jack fails to deliver low frequency sound and bass.

    The sound quality is very terrible.

    I have installed the latest firmware (QKQ1.WW_Phone-17.2017.2004.424-20200414) and the problem still continues.

    I kindly request asus to fix the problem.
