Issues with Inkpad 840

Hello,

I have encountered a couple of issues with my Inkpad 840 and wanted to find out whether they're software issues or known quirks or whether i received defective hardware (and, in the former case, if anyone knows of a workaround).

1. There seems to be a screen refresh of sorts around 4-5 minutes after whatever my last action was, then another about 5-6 minutes later (i don't think it keeps going though, not sure). This also seems to cause koreader to turn the screen white. All power saving features are turned off, the "Complete Page Refresh" setting has no effect one way or the other.

I was wondering if this is intentional (and koreader just messes up when the refresh happens) or if there's something going wrong.

2. There's a fair amount of ghosting on pages with images (with the normal reader app as well as koreader), despite having set "Complete Page Refresh" to "always".

Another thing i noticed which is entirely subjective at this juncture, as i have done a lot of rebooting and the like: The battery appears to drain rather quickly (nothing completely unreasonable but at the rate it's going i'd definitely have to recharge after 3-4 days rather than weeks).

I have tried both of the available firmware versions (5.4.98 and 4.4), which made no difference regarding the first issue (i'll have another look at 4.4 to see if the ghosting is any better).

I hope somebody can offer some insight.

I've seen the battery issue (mine wasn't that severe), but I have not seen the other issues. They're new to me.

I usually got a week or more and that was with a lot of reading.

I used to see a lot of ghosting when I first got my Inkpad, but I haven't noticed the problem after upgrading to the 4.4.1277 version from the website. I'm referring to ghosting in the built-in readers and pbimageviewer. I haven't used koreader in a while since I'm happy with AdobeViewer.

I think the problem with the page flashing after 5 minutes and becoming unresponsive is common to many PocketBook models. I've noticed it on the 902 and 623 as well as on the Inkpad. I think something is being put to sleep. It usually takes a touch to wake up the device before you can use the UI after that flash.
