Is there an app to stop the settings being changed by accident.

[AC Question]

My other half keep changing things and does not know how he did it and certainly does not know how to reverse it. Need a lock on them which you have to agree to before things change. The most common one is he puts it onto meeting, so it no longer rings so he does not answer the phone.

There are apps and launchers that require a password (or at least an "OK") before changing anything.
