Nine 9 tips before putting your Android Smartphone or Apple iPhone for resale


Many people are likely considering selling their old smartphones to upgrade to the latest models released by OEMs, featuring innovative features and new operating systems. However, before selling your smartphone to a friend or a company, it’s crucial to take certain steps to avoid potential cyber embarrassments.

1.) Uninstall Banking Apps and Gateways: Given the holiday season’s enticing offers, particularly when making purchases on credit, it’s essential to uninstall banking apps from your device before selling it. Additionally, remove all UPI gateway apps to prevent any compromise of your banking applications.

2.) Clean Up Call Records and Messages: Before selling your device, it’s wise to clean up call records and messages. Opt out of the sync option before deletion to avoid unintentional replication on your new device through cloud synchronization.

3.) Back Up Videos, Photos, and Docs: Prioritize backing up your videos, photos, and documents using services like iCloud, Google Drive, or other preferred cloud platforms before initiating the deletion process.

4.) Use an External Hard Drive: If concerned about ISP data issues or mobile carrier data restrictions, consider backing up data to an external hard drive before deletion.

5.) Logout and Reset the Device: To erase all data, reset your device after logging out of mobile applications. For Android phones, consider deleting your Google account.

6.) MicroSD Card Removal: Many smartphones with hybrid SIM slots allow for additional SD storage. Remember to remove the SD card when selling your Android or iPhone.

7.) eSIM Management: For phones using eSIM technology, delete it in the phone settings before selling. For regular nano SIM-based phones, remove the SIM card.

8.) WhatsApp, Instagram, and Facebook Backup: Before selling, back up your WhatsApp data, remove the SIM, and be cautious of service synchronization. Uninstall Instagram, Facebook, and WhatsApp to ensure a clean transition.

9.) Clean and Prepare for Sale: Switch off your smartphone, clean it thoroughly with a suitable cloth, and use specialized cleaning liquids to eliminate dust, fingerprint marks, and bacteria from the screen without damaging internal components. Having the original box, accessories, and invoice can enhance the resale value.

By following these steps, you can sell your old smartphone with confidence, minimizing the risk of any data-related issues or cyber threats.
