Forensically wiping a phone ensures that all data is irretrievably erased, protecting your privacy and sensitive information. This process is crucial if you’re selling, donating, or disposing of your device. In this guide, we’ll explore how to effectively and securely wipe your phone, using both built-in features and specialized software.
What Does It Mean to Forensically Wipe a Phone?
Forensically wiping a phone involves completely erasing all data so that it cannot be recovered, even with advanced recovery tools. This process is more thorough than a standard factory reset, which may leave some data accessible to skilled technicians.
