Using a generic QR code scanner (https://itunes.apple.com/us/app/free-qr-code-reader-barcode-scanner-for-iphone/id903799541?mt=8) , for the Upbit image, the scanner reads the Q address only, for the Explorer image the scanner reads “qtum:QSyiND…?label=QTUM Mobile Wallet” where QSyiND… is the full Q address, and the scanner cannot read the QR image from qtum-qt.
