========================================
Hi,
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:
- Reset app settings
- Tried safe mode - but there is no music player so doesn't count
- 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 in advance for your help.

Thank you for your reply, just let me know if you need more details from me.
this is definitely a software bug that is related to sound output not through built-in speakers but through headphones - therefore proposed solution would not help with this issue.
Okay......my loud speaker volume was very low even with stock oreo firmware and some popular custom roms......so I concluded that issue must be to do with hardware hence I suggested this.......
if you know how to unlock bootloader and flash a custom recovery I would suggest to try flashing stock oreo firmware and check if it solves the issue.........that would be the quickest solution......provided you already know how to unlock bootloader etc.
the latest 424 update description mentions fixing low frequency sound issue - I guess I am going to wait for that update
Hi uspenskiy.ua,
A new firmware update version WW-17.2017.2004.424 has been released. We have improved the sound issue.
You may manually download it from our website: https://www.asus.com/supportonly/ZenFone%20Max%20Pro(M1)(ZB602KL)/HelpDesk_BIOS/
How to update firmware: https://www.asus.com/support/FAQ/1009748/
Please make sure to back up your data before updating.
Hi @Christine_ASUS ,
appreciate your providing update on that. I tried downloading and updating my firmware manually - unfortunately it didn't work.
I have Global version of ZB602KL Zenfone Max Pro M1 phone and I used indian version of Android 10 beta to update my firmware to WW-17.2017.2004.407.
Can you please advise if there is any way for me to update my firmware to global version from currently being on indian WW-17.2017.2004.407 ?
Thank you in advance for your help.
Hi uspenskiy.ua,
To make it clear, you would like to upgrade from WW-17.2017.1911.407 to WW-17.2017.2004.424, right?
Have you tried upgrading "manually" to this version but it failed?
If yes, compare to the "Manual Update" guide in "How to update firmware" I provided before, could you tell me the issue detail and the steps you perform? Have you facing any unexpected password key message, or have you receive any error message?
Also, please check your inbox for a PM I've sent you.
Hello Christine ,
I just installed 424 version , sound quality improved in earphones but there is no bass still .
Also pubg and call of duty mobile still not fixed
Can you reproduce exactly same behaviour as I have:
The same.
The problem occurs only when headphones are connected via Bluetooth.
Essentially this build comes with bad sound quality especially with earphones (garbage)
Hdpubg and call of duty mobile not fixed
Battery life
And the bad sound when calling that u mentioned witch appeared many months ago still exists
Hi Supertambov, uspenskiy.ua, and romach3
Please provide me the information below:
1. Are all of you having ZB602KL with 424 version?
2. The bass issue occurs in which condition? (cable earphone/bluetooth oearphone/phone speaker)
3. Could you provide any comparison in audio or video?
4. Does the problem appear on the preloaded app-Play music?
5. Does it appear on Youtube? Could you send us a music link and indicate the timepoint of the problem?
Hi Supertambov,
Furthermore,
>PUBG/Call of Duty HD
I have forwarded the information to the relevant department. We will keep you updated and your consideration will be very much appreciated.
>Battery
Do you mean battery draining? It happens in idle mode or using (which apps or functions?)
>Bad sound when calling
Is the quality worse compared to Version P? Using what kind of device(cable or blue tooth)? Any audio calling app or preloaded app?
Hi @Christine_ASUS,
I updated to 424 - this did not help to resolve issue.
As mentioned in other post - no bass issue is most probably related to microphone because making a call brings back bass to the sound.
therefore please fix this bug so we don't need to make a phone call to be able to listen to the music.
Thank you
Hi all
I have forwarded the issue of Bass to the relevant department. We will keep you updated and your consideration will be very much appreciated.

Can u please fix the bass issue it was fine in Android 9 but in the 424 update just ruined it.
Hello @Christine_ASUS ,
There is no drain on idol mode , battery not bad in android 10 but i noticed it s slightly better on pie . About sound when calling . When having a call without earphones the other person hears my voice low and sometimes with echo especially when using apps like WhatsApp or Facebook messenger , and the problem is worse when using speakers . Users have been reporting this issue since pie . Thank you .
Hello @Christine_ASUS ,
Yes i ama using zb602kl with 424 firmware version . At first i did notice any improvement in sound quality but after multiple restarts it got better ( YouTube , music and everything ) but it still not good . It lucks bass and clearness . I m afraid to restart my phone again , i m afraid it will be worse again lol . Pie has an amazing sound quality , please just make it like that . Thank you
