executeShell only executes command when input i

[ligi]

this does not execute the command:
device.executeShell("input keyevent KEYCODE_POWER")

but this does:
device.executeShell("input keyevent KEYCODE_POWER").reader().readText()

I would expect the first command to also work

Both should work with the latest master
