Smartphones are not safe

It is necessary to create a smartphone where, as a separate encryption layer on top of the encryption based on the security chip key, there will be a user password, so that even if the security chip is hacked, it will be impossible to decrypt the data since the password will not be stored anywhere, and of course, so that the phone enters an encrypted state not only after a reboot, but also after the screen is turned off. It is also desirable to encrypt the entire system except for the password entry window and the processes responsible for decryption, rather than just the user data, in order to reduce the attack vector.
