Double-tapped the COME download action
After a double tap, check whether the browser created one request or two. Avoid assuming that both taps started independent COME APK downloads.
Count actual transfer entries
Read Downloads for entries with the relevant name and time. One page can handle repeated taps in different ways. Only the browser records show whether there is an active duplicate or merely repeated navigation.
Use one identified completed copy
If two transfers really exist, let the useful one complete and use the browser supported cancellation for an unwanted duplicate when appropriate. Do not interrupt an Android installation simply because the source button was tapped twice.
A practical example
Two page taps produce one completed entry and no second file. There is nothing to remove just because the gesture happened twice. If two files exist, compare their records before choosing one.
Keep the surrounding steps clear
A browser download has its own record. The page that starts the request, the transfer entry and the saved file are three useful checkpoints. An animation on a webpage is not the browser's completion result. Inspect the record before beginning another copy, especially if the first attempt could still be running.
Android installation is a later step. A package can be completely saved while no application has been installed. When a completed file is selected, read the receiving app and Android's actual message. Do not disable device protection or accept an unrelated permission because the file task is inconvenient.
If the same problem returns after one deliberate check, keep the destination address, time, browser name and exact message. That is more useful than a list of repeated taps. Avoid deleting working app data, clearing every browser record or creating another account to diagnose a transfer problem.
What a completed answer looks like
The number and state of actual transfers are known, and installation proceeds from one deliberately identified file.
