After last 2 or 3 updates my phone makes lourder noise after phone call when disconnected for a second.
Can asus or some can provide solutions to fix this.
This is very uncomfortable
I have never heard of this issue before so it must be something with your phone.
Backup your phone and then you try and clear your phone app and see if that helps. Settings -> Apps & notifications -> see all apps -> 3 dots in top right corner -> show system -> scroll down to "phone" -> Storage & memory -> clear storage -> OK
If that doesn't help, then try with a factory reset.
