Max Brightness

When the clerk at Meijer uses their handheld scanner on the MPerks barcode on my Pixel 7 it typically takes four or five attempts before it's successful and sometimes they have to scan it using the stationary scanner, which typically works the first time.  I now know why, courtesy of the Frontier Airlines app that's scanned when I board their planes.

As shown below, the Frontier app has an "Allow boarding pass max brightness" option that does exactly that.  I thought that probably was to improve their scanning accuracy, so the next time I went to Meijer I manually cranked up the brightness before having them scan my MPerks barcode.  Bingo, worked the first time!  Case closed.
