Let me give you another perspective - you cannot fight a foreign state that wants to hack your device and access your personal data. Even Apple iPhones, who often taut how "secure" their devices are, remain vulnerable to state spywares. A secured device, at most, will protect your data from the police or lay cracker or malware, who lack the means to use more sophisticated methods to access your data. When Android forks (like Lineage OS or Graphene OS) advertise that their Oses are more "secure", with better "data protection", what they mean is that their OSes try and prevent data leakages to the OS vendors (like Google or Apple or other BigTech) or to online services integrated with the OS or through system and user installed apps. In other words, "privacy and security" primarily means that they try and prevent surveillance capitalism.

Actually Graphene has been shown to be resilient (uniquely) to some of the forensic tools used by governments.
