🐛 Describe the bug

Android/test-llama-app (mobile-job) fails due to corrupted apk downloaded from S3. See logs:

You can follow the S3 link and download it manually to reproduce the issue by running unzip mobile-job-android-9954110435-1-2024-07-16-ZOfaUHWN_ci.apk, you will see detailed error like

Archive:  mobile-job-android-9954110435-1-2024-07-16-ZOfaUHWN_ci.apk
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of mobile-job-android-9954110435-1-2024-07-16-ZOfaUHWN_ci.apk or
        mobile-job-android-9954110435-1-2024-07-16-ZOfaUHWN_ci.apk.zip, and cannot find mobile-job-android-9954110435-1-2024-07-16-ZOfaUHWN_ci.apk.ZIP, period.

I tired build the same apk locally and it's just unzipped fine. So I think the issue is either the uploading to S3 or downloading from S3 is not done correctly.
