On the Samsung Galaxy A6 Android phone, the screen resolution is 720x1480. This is 18.5:9. However, sbrick app incorrectly seems to detect the resolution to be 21:9 and therefore allows only to choose 21:9 profiles instead of allowing 18.5:9 profiles. The 21:9 picture is then distorted and compressed in one dimension to fit into 18.5:9.
Two solution suggestions: either fix the aspect ratio detection; or allow any aspect ratio profile on any phone (and only inform what the best fit is) and use black borders to make it fit (much like on a TV screen).
