Why Should You Erase Data, Before Selling or Exchanging Old Smartphone?

Are You Selling or Exchanging Your Old Smartphone? Make Sure You “Erase” Your Data!

Recent market research has confirmed that more than 500 million people were using smartphones in India as of December 2019, which is a 15 percent increase from 2018. A key reason behind this rapid growth is Chinese brands such as Xiaomi and Realme. They are offering the latest high-spec smartphones at cheaper rates.

Earlier, people used to stick to a smartphone for years. But now devices are changing hands (exchanged, resold) faster than ever due to affordable prices. Other Key reasons behind smartphone consumption trends include— availability of many makes and models. Consumers’ preference for the latest technology, and lucrative exchange offer from online and offline retailers.

When you buy a new smartphone, you either sell it to a reseller or exchange it. Most users delete data or factory reset the device before picking any of these options. But they are unaware that deleting the data or formatting their smartphone doesn’t remove the data from the phone memory. The data remains inside the storage and you can easily recover it by using data recovery software. This fact underlines an immense threat to your personal data that can be stolen from your used smartphone. This leads to implications such as identity theft, financial losses, harassment, and even legal troubles!

A lab investigation of second hand (used) devices conducted by Stellar ascertains this fact. The study had revealed low awareness levels among users regarding the secure disposal of their smartphones and other data storage devices. The study investigated a very large sample of 311 used devices and storage media. This includes mobile phones, memory cards, and hard drives. 222 of these devices contained Personally Identifiable Information (PII) and sensitive personal data.

About 71% (or 7 in 10) of these used devices were dumped by the users after formatting the device or deleting the data. A significant percentage of users had taken no action at all and the data was found accessible. Overall, the data on these devices could be easily recovered using data recovery software, and therefore was highly vulnerable to theft and misuse.

Leverage “Data Erasure” Instead of Deletion or Formatting Before Reselling or Dumping Your Old Phone

Smartphones are full of personal and sensitive data including photographs, videos, credit card details, bank account details, Aadhaar Card details, etc. Such data if it falls into wrong hands can pose a big threat to you. Hackers and data brokers can recover personal data from your old phone, posing threats in the form of extortion, financial frauds, identity theft, and more.

To avoid a data breach, ensure that the old smartphone you are reselling does not hold any personal data. Use data erasure software to erase the data from your old phone and ensure complete data privacy. Don’t rely on deletion and formatting. ‘Deletion’ simply removes addresses to the files stored on phone memory, the actual files remain inside your phone. Similarly, ‘formatting’ is a method to prepare the storage media for reuse, it may not remove the data that can still be recovered.
