How setup / enable Samsung Galaxy S8 Plus anti-theft & security features including screen locks [Tutorials]

Your new Samsung Galaxy S8+ comes with a lot of security features you can use to make sure nobody can access your device and your data without your consent. For a phone that’s worth almost a thousand dollars, it is just right to make sure nobody can use it in the event that you lost or misplaced it.

In this post, I will walk you through in setting up the anti-theft feature of your phone so that nobody would be able to use it even if they resort to a reset to gain access. It is actually the “kill switch” of your phone and it only takes effect if the phone is reset through the recovery mode with your Google ID still signed in and a screen lock activated.

Aside for the anti-theft, your Galaxy S8 Plus also comes packed with iris and fingerprint scanners so you can gain access through biometrics. Smartphones have evolved so much since 2010 and now we’re enjoying features brought about by new technologies. So, enjoy what your phone has to offer.

How to turn On / Off Samsung Galaxy S8+ anti-theft feature

Before, when you have issues with your device, you can just reset it through the Recovery mode and everything will be deleted and the phone will be brought back to its factory settings as if it’s new. Today, however, you cannot just do that anymore because you will be locked out of your phone and if you don’t know what your Google ID and password is, then you can never use your phone again. This feature is called “anti-theft” because in case you lost your phone, other people who don’t know your Google ID and password won’t be able to gain access to it as it renders the phone useless.

I cannot stress enough how important this feature is so make sure you use this and enable it the moment you open your phone for the first time. Here’s how…

  1. Hi new s8+ purchased. Difficult to recognise pattern security. Doesn’t allow much time to draw pattern. Or doesn’t recognise pattern being drawn. Lots of difficulties trying to unlock phone. Why does this happen? How can we fix this issue. Still want to use pattern, not other security types. Has anyone had same difficulties?
