    How the app decides which camera to use? It has three

    the back camera is used, and if you meant there are 3 in the back that is up to the system, maybe try cleaning them 😅

    ok so probably it is a problem with the QR library we use, sadly IIRC we can't upgrade it without having to drop support for android 5

    I'm curious... how important is to keep support for this old version of Android?

    more than for your particular device 😁 sorry

    but eventually it will get dropped when there are less remain android 5 users
