Introduction
Selling an old smartphone is a great way to recover some value before upgrading to a new device. However, many people forget that their phones contain personal information such as photos, videos, contacts, messages, passwords, and banking details.
Before selling a mobile phone, it is important to remove personal data completely and prepare the device for the next owner. Following the correct steps helps protect privacy and prevents unauthorized access to sensitive information.
