In the early days of computing, people dreaded when they had a problem with the software because it was never an easy fix. Smartphone operating systems changed all of that.
An operating system like Android has a built-in feature that allows the user to take a hard reset (factory reset). It’s a feature that can be used any time you have a problem that you don’t know how to fix.
The Android OS is exceptionally reliable in general, but as we’ve seen with Microsoft’s Windows of late, an OS can cause you some problems after you update it to newer versions. And updating is just a part of life that we’re all going to have to get used to—it means not only extra features and updated design elements but also critical security updates.
In addition to solving problems related to Android’s functionality, taking a hard reset is what you ought to do before selling your smartphone. Most people keep their phones to a point where they’re now officially outdated—and even to a point where they may no longer work due to an ailing battery—but it’s still safe practice to delete everything that’s on the software just in case someone does decide to pick it up and have a play around. The way to do this is by taking a hard reset—once the hard reset is performed, it’s no longer possible for people to see any of your pictures or any other data that was stored on your device’s NAND-based flash storage.
The Android operating system since Android 5.0 Lollipop now comes with Factory Reset Protection (FRP). This means that it is no longer possible for someone to steal your device, apply a factory reset to it and then take ownership of it as if they never did anything wrong. Now with Factory Reset Protection, if someone else decided to hard reset your device, they’ll still need to log in to the owners Google account before they can proceed. The heightened security is excellent for most people but does come with one downside: if you can’t get back into your device because you can’t get access to your Google account, you’ll need a workaround. And there are tools out there now that can help you gain access to your device again if it ever happens to you.
