Are you going to sell your old Samsung Galaxy phone for a newer version or just give it to a friend or an acquaintance? If so, you need to safeguard or even delete any information that you deem private in nature. Most specifically, you need to permanently erase sensitive data such as contacts and messages. But while this may be a simple task on some phone models, erasing contacts from your Samsung Galaxy is a different story all together. If you just delete the contacts casually, there's a possibility of another person recovering the contacts and using them maliciously. Based on this, here is a guide highlighting the reasons why and how to permanently erase contacts from your Samsung Galaxy phone.

Reasons to Wipe Contacts on Samsung Galaxy

- Identity theft. There's no denying that Samsung galaxy phones are laden with features. But in the midst of increased capability and modernity lies identity theft risks as well. Thanks to the compatibility of the Android system that runs on Samsung Galaxy as well as the availability of devious third party applications, criminals and hackers can retrieve deleted contacts and use them maliciously.

- Account hacking. The risk of having your accounts hacked are as real as the possibility of identity theft. The fact that a Samsung Galaxy can accomplish as many tasks as personal computers mean most people may end up saving some of their sensitive data in their Galaxy's phone book. If such information gets in the wrong hands, there's every chance you'll get hit by hackers.

- Ruined reputation. While many malice oriented individuals would concentrate more on draining your financial accounts where possible, there are still others who would rather use your name with an intention to ruin to your reputation. This includes soliciting for money, bullying others and sometimes even worse. This can bring your career and character tumbling down.

- Spoofing. Well. Phone hacking isn't as common as computer system's hacking. Yet when it occurs it can have devastating results. If you just deleted your contacts from your Samsung phone temporary, hackers can retrieve your contact information and use it to track you through GPS, access your voicemail, or even make annoying prank calls to your contacts. The worst part is that your callers won't have a way to know it isn't you at all.
