Seriously, why do people make such a fuss over this? Yes it's a bug, yes it's a serious bug, but seriously:
A) if they say they will have a software fix in a few days you won't have to buy a new one so that point is moot. (and it worked that way for the whining issue too). They are fixing the issue in a few days, in fact firmware updates have been coming out once every few weeks since the device was released, so I'd say support is pretty good. My archos gamepad 2 had one, (ONE) firmware update in 18 months and there were various issues that remained with it. OVerall android lag sometimes, button mapper crashing in the middle of the game, these were never fixed. Last time I checked, archos was in France and this was a western country, so I don't see the angle of "evil Chinese" holding up here.
B) There is no way this can cause any damage if you charge your device in standby or turn it off then charge it while it's off.
So it's not exactly the end of the world. And their response is good. Fixed in hardware for new units, free firmware update for all existing ones. We also know their customer support, if you buy a device in their aliexpress store, is exemplary - they replaced one on their costs with two freebies included while the issue was so small the customer played on it happily every day.
So what the hell do people mean with "bad support" ? Yes, their manufacturing procedures
are not that great. Duh, it's cheap and they're a small company. This means a higher percentage of devices while arrive broken. But they replace those at their costs with no complaints, and for the vast majority that does work correctly, updates to fix issues are released every few weeks. Also, they happily offer information AFAIK to skelton and other firmware developers, and even include patches made by these people in their official firmware updates.
What better support could you expect from a company with the limited resources they have?
