"Can't find end of central directory" error on Android devices with zip files larger than 400KB

Hi, I'm encountering a recurring error when using JSZip:

Can't find end of central directory: is this a zip file? If it is, see https://stuk.github.io/jszip/documentation/howto/read_zip.html

Is there a known issue with JSZip failing to extract zip files larger than ~400KB on Android browsers?
The issue happens across multiple Android devices, but doesn't occur on desktop.

Seems similar to issue #632 — could it be related to minification?

After investigating the error occurring when processing ZIP files larger than 400KB on Android devices, I've confirmed this is not an issue with JSZip itself.

The root cause was file corruption when downloading ZIP files through specific browsers on certain Android devices (Galaxy phones). Analyzing the error logs from my personal project, I verified that users who uploaded files around 400KB from Android phones experienced this issue.

Therefore, this is not a JSZip problem but rather corruption during the file download process. Since the issue has been identified, I'm closing this ticket.
