Early smartphones were pretty basic. They relied on apps to do a lot of the more powerful and interesting things. For example, scanning QR codes—you needed to download an app to do it. That’s not the case anymore.
Flashlight apps have experienced a similar trajectory. What once required a third-party app from the app store is now a baked-in feature on Android and iPhone. You don’t need a flashlight app anymore, and you don’t need a QR code scanner app anymore either.

What Is a QR Code Scanner?
A QR code scanner is simply an app that can detect QR codes. A QR code is a form of barcode that contains information. You and I can’t read that information with our eyes, but a QR code scanner can.
QR codes can contain many different things. It can be a simple URL, plain text, a contact card, PDF, email, phone number, Wi-Fi network details, or even a prefilled text message. There’s a lot that can be done with QR codes, which is why you should know how to scan them.
All you have to do is point the app at the QR code and you’ll see the information contained in the strange boxy pattern. Except you don’t need an app anymore.
The Problem With QR Code Scanner Apps
The main problem with QR code scanner apps is they’re unnecessary. Both the iPhone and Android phones have built-in methods for doing this.
The story is much the same over on Android. Samsung Galaxy phones can also scan QR codes with the camera app. If yours can’t do that, a shortcut can be added to the Quick Settings panel.
Beyond simply being redundant, QR code scanner apps have the same security and privacy concerns as flashlight apps. Many of them abuse permissions that are not necessary for scanning a QR code. It’s a sneaky way to hide malware in an otherwise unassuming app.
At the end of the day, QR code scanner apps are just a relic of the early smartphone era. Android and iOS have evolved to include features like this that make highly specialized apps unnecessary. It’s a bit of a bummer for developers who were making nice apps, but easier for you.
