========================================
Dear Asus
After android 10 update, I have issue with the sound output of the device. Loudspeaker output is ok but 3.5 mm, BT Headset & USB audio output is so cheap that there is no bass android the audio quality is very bad. And earpiece volume is too low.
Urgent need of solution.
Thanks.

I suggest there is a high possibility of faulty hardware, device or earphones. The sound performance of my device in Android 9 and Android 10 works properly. Normally 30% volume while using the earphones is really loud for me. If you suspect any software issue like 3rd party apps, you can give the Factory Reset a try.

Thanks for the support.!👍
It means hardware failure. Because a few days ago I installed stock Rom via Computer.

Something i need to know...If you can tell, it'll be grateful.
Last time this device was running on Android 9.
I unlocked the bootloader using ADB command. (Not using the official Unlocker app)
And Give root access using magisk.
Then The Wi-fi, Camera, Flashlight and incoming-outgoing calls doesn't work. (Internet Working)
Why did this happened?

I think (ZB631KL) NFC variant doesn't have problem.
