I’m documenting this here as it does seem to be too much of a delay especially in Ubuntu Mate 19.04.
Maybe this is normal? I’m not sure?
One more issue(?) i found. When i plugged in the supplied charger, sometimes the device still did not start charging. Either that or the icon takes 3~5secs (or more) to indicates that the device starts cgarging. Does anyone happens to have this issue as well?
