How to Safely Delete All Data on Cellphones – If you want to sell your phone, the first thing you need to do is delete all data, here's how to safely delete all data on your phone that you can try.

For those of you who want to sell a smartphone, you have to delete all the data on it. Please note that using only the reformat approach is not sufficient.

Kaspersky's Global Research and Analysis Team (GReAT) offers a robust solution to ensure that your data is completely wiped when selling your phone.

How To Delete All Data

The experts at Kaspersky propose a variety of approaches. First, make sure that the file storage space has been overwritten. To perform an overwrite, which is often known as “destroying”, software is required.

Some security systems, such as Kaspersky Total Security feature this kind of data deletion capability in the device's File Shredder, thereby ensuring that the selected data is overwritten multiple times so that it cannot be retrieved.

Second, you can also use Windows' built-in data deletion program, Cipher, which is generally used for encryption, but can also be used to destroy files from a hard drive or make them unreadable.

Head of GReAT Europe Marco Preuss stated that in general consumers should always store data on personal devices encrypted, in case the device is stolen or someone gains unwanted access.

"Depending on the type of information found, when personal data falls into the wrong hands, it may put not only yourself at risk but also your friends and family or even your organization," he said.

According to Germany's GREAT head Christian Funk, it's a common misconception that simply erasing data or reformatting a storage medium is enough to erase data.

“If there are even a handful of tech-savvy individuals, they can take this data. That's why it's so important to do a thorough cleanup,” he said.


In the article above, we have provided a list of ways to delete all data on your cellphone that you can try before selling your cellphone.
