Zenfone Max Plus M1 ZB570TL

Kuis Kiske

In many asus smartphones, the Asus Zenfone Max Plus M1 ZB570TL has a loud and best sound when listening to songs using earphones with AudioWizard, but unfortunately because when upgrading to android 8 the display it always lags and the speaker sound is small.
To listen to songs using earphones is satisfying.

Could your please tell me your FW version?

firmware version : Settings>System>About Phone>Build Number

If you try to update to the latest version, does the issue still persist?

Yes, I use the latest version, and the screen display is still lag and slow.
When I use android 7 everything goes smoothly, when I upgrade to android 8 the screen display hangs out.
What should I do?
I can't downgrade to android 7.
