I'm not trying to solve the issue, just warning people pocketbook is not that good.
The manual on my device also mentions the cloud, but it is just wrong. I think they have regional partners with ebook stores that customize it.
Though I think you are right it isn't Android and I misremembered. I thought thats why it has a dual core cpu and make wonder why it's so slow after boot until it's ready to turn pages.
I can't speak to how their distribution is resulting in selling devices that don't have advertised features enabled. It is weird they would allow this while keeping their branding and same device name (maybe they are working around some trade restrictions?) So that is not good, but I don't know how widespread that issue is. And as I pointed out in my response before the edit, this seems straightforward to resolve if you buy from somewhere that has this issue.
Not to belabor the point, but in my original post I mentioned how PocketBook devices are specifically not Android as an advantage in terms of battery life.
I suspect that what you are experiencing with regards to it being "slow" to resume an in progress book and allow navigation may be due to your settings. The PocketBook has a sleep mode that allows quick resume for reading. How long after it goes to sleep before it powers all the way down is fully configurable from disabling it to waiting your choice of many options between 10 minutes and 48 hours. IMO the cold boot time is acceptable and I did not notice a difference from my 1st Gen Oasis. The power loss if you fully disable its auto power off is still great, although I haven't used it that way much beyond when I first got mine so I don't have a comparison to my Oasis.
That being said, I don't have the same model as you so maybe there is a significant difference between them in performance, but it would be easy enough to check independent reviews if I was trying to decide between them.
