Comment 4 by briander...@chromium.org, Feb 24 2018 

Stefan, was this regression expected?

Comment 5 by szager@chromium.org, Feb 24 2018 

No, it's not expected.  I'm trying to debug it, but as far as I can tell, we don't currently support any way to run a sampling profiler on the render process on android.
