sometimes is also good saving a screenshot of your Bitcoin phrase and sending a copy to your wife as a back up plan.
Do you know the reason why most wallets disable mobile screen recording and screenshots from their wallets? This is because it's considered risky, as your mobile phone is not your private phone, you can't guarantee not sharing the phone with anyone on one to two occasions, and you can't also be sure of which third-party apps have access to your wallet.
Many people just want a shortcut and taking a screenshot is one of the shortcuts because they only need to swap the screen of the device and it's done but don't realize it's a mistake because of minimal knowledge and think all the available features can be used to make life easier.
If we want to become Bitcoin as an inheritance then teaching it to the person who will receive the inheritance is the easiest way but not giving it access to our wallet because we still keep all information confidential with high security, and those who receive the inheritance will only get access to it after we die by telling it in the will where we keep all these important things.
