Aura Never sign out of Kobo....

[ipse]

...lesson learned: this wipes out your settings and forces a reload of the library.
Pretty annoying (to put it mildly) especially as in my case it takes 2+ hrs to load 800 books (all my library).

I guess I got spoiled using Android tablets (I LOVE FBReader, especially with the TTS+ plugin) but some of the shortcomings of the Aura are baffling.

You can definitely discard my comments and frustrations as I'm very new to this, but I expect I'm not alone. I wonder how much is eInk getting for each device (in royalties) as the hardware performance and capabilities puts these readers at par with 50$ Chinese 7" tablets. So why the higher price?
Considering the price of eBooks, one would think the readers should be almost free...see the case of inkjet printers.

E-ink is a niche market compared to tablets. I agree e-ink reader software is limited and often unstable. This is why I choose to use rooted Android on a Nook STR. Indeed I am posting this post using the Nook. You can achieve something similar on a Kobo...It will certainly run FBreader.

Yes, that is correct it does that and it is expected that it does that. The licensing of ebooks is to a particular user. Logging off means removing those books so another user can logon and read there own books.

Are you telling me that if you logged out of whatever account identifies you to the Android device, it wouldn't remove all the "stuff" from the device? I would have expected it to remove all the apps that had been bought for that account plus all the data associated with the account. If that doesn't happen, there is a big chance of data being leaked to someone if all that is left when a new use logs in.

I think people are saying this is why the devices are as cheap as they are. That is definitely the reason given for the Kindle prices. The e-ink screens seem to be expensive. From memory, someone was searching for a replacement screen for a Mini and the best they could find was around $US40. Not that much less than the device retailed for.

I'd say yes to that, I am sure I have messed with changing google accounts on my tablet & I have yet to see any apps , photos, videos etc. disappear, OK, some paid ones might refuse to run I guess, if not longer correctly signed in, but certainly they are not zapped.

The Kindle app will delete its bought-from-amazon books, yes, if you log out of that . I have not tested what it does with any sideloaded books. I think in Kindle for PC they stay as-is though

with apps, consider the scenario where parent buys phone or tablet for child, Parent then conencts to google play & buys. installs apps via parent's account.. Then parent reregisters with childs' google account ( that has no associated credit card or wallet), to prevent future accidental purchases. you would not want apps to get zapped by Google in that scenario

I can also confirm an instance whrere we cleaned up a Samsung smartphone in order to give it away to a friend. I did the factory reset thing , expecting that to wipe everything. It wiped the logon-to-google details but it left all the old address book entries still on the phone within the contacts tab! ( On the phone, not on the sim card! )

This would be done via adding a secondary account to the phone, the main account would still be there, both accounts would then have access to the same apps

If you remove the primary google account from android (not sure if this still needs a rest to do this) all google play content will be wiped

for the Samsung, that must be local data, contacts from google would have been wiped if you did a reset

I did do a full Samsung reset to factory default, and a fresh isntall of latet firmware yet the address book survived!.

But this was a samsung galaxy PRo android phone, which does not use the google contacts system- instead it had a horrible system that linked only to it's own Kies desktop software ( on the rare occasions that you get that software to actually work). Actually getting contacts from that into google was a nightmare - I had to go via excel then I had to patch up lots of fields that did not populate properly. Keis, in its wisdom, has no print facility so we had to make our paper back up of the contacts list by grabbing screen images one at a time, as we scrolled the list!

it is probably safe to assume that a modern Goggle phone would do a better job of wiping stuff if log in was changed. but that's content "stuff" as in emails, addresses, not apps as in games, utilities....

I can see why Kobo does an all or nothing approach, because all content is in a single big database.

On , say ,a Sony or a kindle reader, you could change /delete/ deregister your store login account data but all local content would be intact still, at least until you forced a a sync with the store servers. & even then I'd expect side-loaded epubs/ mobi files to be left as-is..

This is not my experience.

I accidentally deleted all my cookies, when I only wanted to delete cookies for one day.

When I had to log back in to Kobo, my 180+ ebooks were readily available.

Perhaps it's because I didn't have 800+, as in your case?

The Kobo software is totally dependent upon the database it maintains, the database is susceptible to corruption. Logging off your Kobo account is one way to force a reconstruction of much of that database.

The alternate reading software, that you can add to your existing Kobo provided reading software, do not use a database in that manner, and require no lengthy processing. An install guide.

Just wondering if this has anything to do with the way many apps now are sandboxed

so for example with the address book

If I use the default settings for it with google, all data gets stored where the app specifically wants it, delete the app or reset and it takes the data away with it

If the data is sideloaded (address book from kies) then when the app is deleted, the data is from another source not tied into how the app wants it, so the app gets reset but the data remains ready to be imported to the app again

Not sure how the kobo e-ink devices work
signing off I would expect it to remove your kobo purchased books, but side loaded content I would expect to remain on the device (but would need to be re imported back to the library)

got me curious now, have an old Samsung phone, might need to try a rest and see what happens

Thanks Ken...I think I will have to go that route, as rebuilding the db takes an insane amount of time.
I actually came to like the reader provided I use CoolReader instead of the default.

On, say, my Kindle reader, you can log out and sync until you are blue in the face -- nothing whatsoever will be deleted. Not unless Amazon specifically messages your Kindle saying "Hey, you've got this library book, which just expired, please delete it now."

ok but I think the kindle-for-tablet apps work differently. I am fairly sure that I had books on tablet, downloaded from one amazon account, then I unlinked ( but did not delete the app) in order to add amazon app store which I then needed to link to a different amazon account. I think that all the locally stored books went away as soon as I de-linked

I then found that I can't have amazon app store linked to one account & also amazon kindle android app linked to a different amazon account on the same device. It seems that for tablets, Amazon link at device level, so the option of "link only this app to a different account" just leads to a registration error.

but kindle for PC is a registration within the pc program , not for the whole PC, so that can be changed as often as you like, I believe. possible with 2 or more windows users, each with their own logins, you could have 2 or more accounts linked, even ?



some more advanced android tablets also support multi user, but I don't have one of those

So you need to learn the rules for your book store and for your device.

it would be a simple PC test if I could be bothered. just get a free kindle book, download it to PC, then go to the manage my kindle amazon web page & delete it from my library, ( which they say means gone for good) - then see if it was still on the PC, I could expend that test to include my Kindle Fire tablet. but maybe someone has already done that & will post the answers

An important distinction to make.

Enormous Yawn... Blah, blah, blah... The device does what it does, deal with it. Another great reason for maintaining a Calibre library. Worst case is waiting while the reader processes the books into the DB. Annoying how slow it is, but *that* could, and should, be fixed with background processing

That is how it works. When you log out of you Kobo account the internal database is replaced by an empty database and the books from Kobo are removed. The sideloaded books are not touched. When you sign in again, the sideloaded books are processed and added into the database. If you have a lot of sideloaded books, that can take some time.
