Suite level flakiness reports, particularly ones that rely on anecdotes, aren't terribly useful. If specific tests are failing, please file bugs for those.

Assign to test owner for further triaging

I got a flake on a similar test download.DownloadActivityTest#testDeleteFiles:

https://ci.chromium.org/p/chromium/builders/luci.chromium.try/android-kitkat-arm-rel/18246

Looking at chrome_public_test_apk crashes from the last 200 runs shows several examples of flaky tests...
https://ci.chromium.org/p/chromium/builders/luci.chromium.try/android-kitkat-arm-rel?limit=200

Should I file 1 bug per test? Could we just disable these tests while they get fixed?

+additional owners of DownloadActivityTest.

I got this flake again, so... ping? Any update?

Sheriffs: could you please disable the test for the responsible engineer? Thanks.
