Could you tell us whether your phone is ZB601KL or ZB630KL?
Could you let us know your firmware version? Settings > About phone > Build number.

rj.hl.12222If you want to slove your problem so you can download your device in Android 9 stable it is a permanent solution Android 9 sound quality is better than Android 10
Sound quality too cheap,low volume problem,camera not work properly, sometimes hang or leg the device.
