Choose the right camera in PWAs, Android and iOS

Currently we try to choose a back camera, but Samsung Galaxy S21 (and probably other new phones) have telephoto/ wide angle lens.

Solution: we should switch between cameras until we find a "normal / macro lens" one.

Here is the video using a Samsung Galaxy M31

You would observe that the camera opens in telescopic view having a large field of view.
inspite of holding the camera about 15 cm away from the laptop, the entire laptop is seen

When the change camera option is clicked, it opens the front camera .. and then after pressing it multiple times, at 0:21 seconds- the actual normal/ macro camera is turned on , and the code is visible very clearly before getting scanned.

In my opinion, if we can have the ability to identify the normal camera/ macro lens and choose it as a default, it would solve the issue.

Update from previous testing:
We have tried installing other apps that are popular in India - generally used to scan QR Code & make payments using the phone. It is observed that there is only one camera option to show the image from the normal lens - and no option to change cameras.
