Do you often run past small black and white pixel graphics and wonder how to read them? Simply photographing them is only of limited help – a QR code scanner is required instead. The good news: you don’t have to install an additional app for all devices.

QR codes usually hide links to websites with further information. But phone numbers, appointments, WiFi access or coordinates can also be encoded in this way. We’ll show you how to stop puzzled by graphics and give you some of the most important Android apps to read.

An important note in advance: A separate app is not absolutely necessary. Smartphones such as the Google Pixel 4 and the Samsung Galaxy S10 can scan QR codes, for example, thanks to a feature in the camera app. In addition, the offers Google Assistant such a practical extension. The functionality is the same for the integrated variant as for the apps, although third-party applications sometimes offer additional functions.

How to use a QR code scanner for Android
The scanning of QR codes is actually always the same: First, start the appropriate application – for example, the camera app of your cell phone. Then you fix the code with the camera and wait a short time. It is important that the code is sufficiently illuminated. Some third-party applications also use the camera flash on request. Hold the device as steady as possible during the detection and wait until the focus has adjusted. As soon as the code has been recognized, the app usually signals the completed process by briefly vibrating and ideally carries out the desired action after confirmation.



This third-party application offers all-round convenience
