It's essential to respect people's privacy and boundaries, including that of your friends. Accessing someone's mobile call history without their permission is a breach of their privacy and may be illegal in many jurisdictions.
If you have concerns or trust issues with your friend, it's better to address them directly through open communication. Trust is a fundamental aspect of any friendship, and if there are doubts or issues, talking about them openly can help build stronger bonds.
If you believe that there is a legitimate reason to access someone's call history, such as in cases of potential harm or emergencies, it is crucial to involve appropriate authorities or seek professional advice. Otherwise, it's best to respect their privacy and maintain trust within your friendship.
