Re: How do I wipe android phone before selling?

Performing a factory reset on an Android phone is a common method for wiping personal data before selling, recycling, or troubleshooting the device. However, there are scenarios where a factory reset alone may not be sufficient to fully erase all data, especially if you have sensitive information on the device or are concerned about data recovery by malicious parties. Here's why a factory reset might not be enough and what additional steps you can take to ensure your data is thoroughly wiped:

A factory reset typically deletes user data and settings by removing the index of files, making them invisible to the operating system. However, the actual data may remain on the storage medium until it's overwritten by new data. Skilled individuals with the right tools can potentially recover this data.

If your device uses external storage, a factory reset may not erase the data stored on these media. Personal files on SD cards or connected USB drives remain accessible unless manually deleted or formatted.

When a Factory Reset Isn't Enough? 

Selling or Disposing of the Device: If you plan to sell or give away your phone, ensuring that no personal data can be recovered is crucial.

Handling Sensitive Information: Professionals dealing with sensitive data (e.g., financial, medical, personal identifiers) need stronger assurances that data is irretrievable.

Security-Conscious Users: Individuals concerned about privacy and data security may require more robust data wiping methods.

You should use more dedicated method in order to wipe Android phone before selling. A factory reset is not secure enough!
