Welcome here I've got Samsung Galaxy a03s, and I'm going to show you how to allow the camera up to scan qr codes at this device. So, let's start by tapping on the camera button to open it, and for now we are on standard photo mode from here. Let's go to the left corner button to open the advanced camera settings, and here at the second place we have scanned qr codes option. So by using the button from the right, we can easily turn it off and turn it on as we need and of course I suggest you to keep the sternum on, because when you have it, you can scan qr codes by putting them inside your camera, and you don't need any other app to do it. So this is really easy and that's all thanks for watching, subscribe our channel and leave the thumbs up. You.
