Asus Zenfone 5 ZE620KL low volume

[Kuis_Kiske]

I hope after this Asus can provide firmware to improve the volume sound of Asus Zenfone 5 ZE620KL which is too slow. Volume has lost by 50% after I upgraded to android Q and remains slow even though I have upgraded to android P again.
I bought Asus because of its sound quality.
Hope Asus cares about this.
Thank you.

Hi Kuis Kiske
Thank you for your reply. My device in Android 9 does not encounter the same issue, if your device still has the issue in Android 9 after the Factory Reset, please bring the device to the nearest repair center for further checking.
