That's really nice that you guys are able to get good test results on Android 4.19 that early after the release :-) Do you happen to run interactive use-cases as well ? I think Jankbench is one of the workload most folk care about for example. Also, did you manage to measure energy numbers for the above tests ? FWIW, I'd like to give a go to TEO on an Arm-based setup when I can. Thanks, Quentin
