I have recently been having some issues downloading .apk directly to my Samsung A20 using the scan code. apk is 4559kb
Issue 1 Having scanned the code and selected the url typically a pop up comes up with a download button, this recently sometimes does not show
Issue 2 The download finishes but the .apk file won't load "problem while parsing the package"
Issue 3 Australian EST between 7pm - 12pm downloads to the PC often take an extended length of time and then fail to be successful
( these issues didn't exist a month ago, downloading the apk using the barcode directly to the phone was quick and non problematic )
Work around
Early morning 5am - 7am I have greater success downloading to the phone, but I can still have issues with the download file not parsing.
I have found that downloading the file to the PC first and then copying the file to the download directory of the phone is typically successful
