Questions on run-perf-tests.py: Step5 & Step8

[AmitKulkarni9]

Hi,
Just need few queries in run-perf-tests.py.

Step5: Enable and clear graphics info dumpsys
reset_graphics_dumpsys(device, package_name)
what is the device here ?

Step8: Download files from device
Is it the dumpsys logs? So once we run the systrace the logs will be dumped in the device? If yes where in the device I can find it ? Is it "/storage/emulated/0/Android/data/" OR "/storage/emulated/legacy/Android/data/"

Thanks,
Amit
