The new trybot will be called "try-nougat-phone-tester" in similar naming convention to the "gpu-manual-try-" trybots, but a bit less verbose.

I suspect we'll wind up renaming both CI and try here -- I know you're partial to including try- in the name, but we've tried to avoid that beyond GPU in favor of having the names match.

Fair enough. Once the new CI and trybot naming convention is decided upon, happy to rename all of these. (It looks like the names of CI and trybots don't currently match.)

Indeed; we've tried to do so w/ newer bots (and a few older bots), but we are far away from getting everything renamed, and I wouldn't want to name the trybot "Nougat Phone Tester" here.

Running first job through this trybot here:

https://chromium-review.googlesource.com/1200387

https://ci.chromium.org/p/chromium/builders/luci.chromium.try/try-nougat-phone-tester/1

My initial guess is that any VR tests in that run will fail. Whatever is isolating the tests for swarming needs to have the DOWNLOAD_VR_TEST_APKS environment variable set when running "gclient runhooks" in order to get the APKs necessary for VR tests (we got complaints about unconditionally downloading them when they were initially added, so we had to move them behind the environment variable).

Nevermind, looks like that's never been set in the bot_update step. Since it's cloning the arm64 builder, everything should be taken care of.

The first tryjob passed the following steps which it ran:

chrome_public_test_vr_apk-ddready-cardboard on Android device Pixel 1 XL (with patch)
chrome_public_test_vr_apk-ddready-dynamicsettings on Android device Pixel 1 XL (with patch)

It failed the following step:

chrome_public_test_vr_apk-ddready-ddview on Android device Pixel 1 XL (with patch)
https://chromium-swarm.appspot.com/task?id=3fabbd157a362910&refresh=10&show_raw=1

apparently because the device that was being tested went offline during the test.

It might be necessary to increase the timeouts on both the waterfall bots and this trybot in order to handle tryjobs that come in on it. That can be done if it looks like the bot is not reliable. For now closing this as fixed.
