Hi, I see that there are existing tests in https://wpt.fyi/results/serial?label=experimental&label=master&aligned, but only for things that don't require actually creating a device.
Do at least these tests also pass on Android? Is any work happening to make Serial testable in WPT in general? Something along the lines of https://web-platform-tests.org/writing-tests/testdriver.html#bluetooth should work.
