Huawei — delete option not available while calling to customer care

When i am making a call to customer care for bank or phone issue, there we must the customer id or phone number which donot have delete button to make the correction. It leads to make me walk to bank or to borrow other's phone. Can you fix it up. Even though it's small a button add and click function it plays a role too.

Multiple screen display should also include the dialer screen too to type the numbers by seeing in other source.

Provide an alternative option to reset the safe password in the situation when i forgot my password and also security question instead of formating the phone.

Minimum limit of brightness during the dark light should be reduced even more as it cause eye irritation more

Sound quality of the music is very poor. Can have the maximum limit extended with improved sound quality.

Provide rename the music tracks option in the music app rather than doing it in files=audios or videos.
I would appreciate it if it's taken care in next software upgrade release.
