Is my Arnova 7h G3 broken? Hardware/Software error? Is this a known problem? Cyanogenmod?

I feel like the only guy on the entire Internet who actually owns this exact tablet right now, so I hope I can find someone else who can tell me if the following behavior is normal (i.e. firmware bugs) or a hardware problem unique to my device.


At first I was very happy with my purchase, for a cheap little toy it did a most things surprisingly well ... or so I thought.


My questions to other owners:


Where is up and where is down in portrait mode for you?


My 7H G3 thinks that the side with the webcam and and microphone is "down" and the one with the speaker is "up". I tested it with several different tools and that's the default portrait orientation - the one that all apps with forced orientation default to.


While it seems a bit odd to cover webcam and microphone when holding it, this is where the device is heaviest and I guess it may make sense to hold it this way.


Can you "lock" your screen in portrait mode without third party tools?


I can't "lock" my screen in portrait mode, it always jumps back to landscape when disabling automatic screen orientation, instead of locking it in the position is currently is. Freeware rotation tools don't fix this and "jump" back to landscape mode when manually enforcing "portrait" and "landscape" or mode.



Does kinetic scrolling / "fling" reliably work for you?


Mine is occasionally behaving oddly. While scrolling itself works fine and the touchscreen doesn't show any issues, kinetic scrolling / fling frequently does not. The second I remove my finger from the screen any list scrolls in the exact opposite/reversed direction (i.e. the "kinetic energy" is exactly 180° reversed), creating a rubber-band effect that makes it impossible to use - it simply bounces back to where I started. This is for the default launcher and any ICS system app and most other apps. There are exceptions, though. Opera appears to use its own scrolling routine and scrolling and flinging works perfectly fine and as expected - but in the default browser and Dolphin it does not.

This happens sometimes and even survived a full factory reset but usually disappears just like it appeared (after putting the tablet aside for a few minutes) - this seems like a very, very odd "overheating" bug if that would be the case.


If I had to guess, these appear to all be software-related problems that could be fixed with a simple firmware update, one we will almost certainly never get.


So: Can anyone confirm or vehemently deny these issues? Should I return the tablet (I still have 12 days to get my money back for it) and hunt for a different one in this ultra-low price range, should I get it replaced for a new one or is there a way to fix the software?


Is anyone successfully running Cyanogenmod on this device without any (notable) limitations?

It feels like nobody else does, but thanks for your help, those links are a great starting point.

I may just give CM9 a shot (shame there is no Cyanogen 10, I could really use multiuser support - although the Allwinner A10 mods should technically work). :)


I found out that the most severe problem, the entirely messed up and worse than broken kinetic scrolling / fling only occurs when the tablet is plugged in / charging. While still a rather severe problem (especially since battery life isn't exactly stellar and charging isn't all that terrible quick) I guess this is a trade-off I'm able to live with for the low price.


The remaining problems still stand but appear to be mostly software related, so once a full backup and restore procedure is possible for me, I'll give CM a shot ...
