This isnt possible.
I guess its possible That is what was displayed under properties....

When I connect my Alita to the PC I get one icon with the Reader. I open that and I see two icons. One for SD card and one for internal drive. And when I click properties both say Format: Generic Hierarchical.

Then I'm afraid it is defective.
I then proceeded and put my SD card out of Alita and into my SD card reader. Now it says FORMAT: exFAT and the opening of my folders was a lot faster. With card in Alita it took a while to load all folders.

Also the most important thing there was absolutely NO PROBLEM with copying files (even 1GB+).

So this is pure Alita fault not the SD card. But I don't really know what's causing this. Software bug? Random write failure of SD slot? I think file size is not a problem either since sometimes it adds 5 files which are all about the same size and fails with the sixth. Copy window closes before ending and I see 5 files instead of 6. It's kinda random. Aside from that it doesn't want to copy failed file anymore via Alita if I try again the copy status bar just go to the previous location and hangs there for a bit then closes.

And again everything works normal on SD card reader as I said.

This fairy tale is nonsense.

Likebook Alita has/d problems with exFAT and a bug related to this was fixed in the last update.

Yup. That's the MTP. It doesn't expose low level details about the filesystem. In windows you see them as "Generic Hierarchical", see https://superuser.com/questions/1443948/what-exactly-is-a-generic-hierarchical-file-system-and-why-does-it-behave-diff

I know that MTP in linux is broken as hell (ie: you can do a single thing at a given time, so copying files while exploring what's already on your device is a big nope). AFAICR windows support should be better, but not as good as a mass storage device.

Anyways for transfering big chunks of data ADB will do it faster, specially if there're a lot of tiny files. Indeed in linux ADB is the only way to bulk transfer data given how broken MTP is.

I have V3.0.1-2020102114 and it says that it's latest version.

Yeah probably MTP problem then. Yes browsing while copying don't work in windows 10 either for me on Alita. And there is some issue with renaming files I think at least when I tried.

EDIT: Thanks pazos for mentioning the MTP problem. I switched to PTP and it looks that it works better than MTP. It's copying manga CBZ files fine although sometimes it gets stuck for a while but never fails.

My Alita intermittently displays a garbled page in Boyue Reader, KOReader, and more rarely outside the reader in the user interface. The garbling can be resolved by hitting the power button on and off, which displays the screen saver and restores the display to a readable state, but on the page following the expected next page.

The bug appears as follows: tapping page X to get the next page (X+1) does not change the display, even with waiting. Upon tapping again, the screen shows what appears to be the superposition of: (1) the original display page X, (2) the ghost (white space for characters) of the intended next page (X+1), and (3) the page following the intended next page, page (X+2).

Thus it would seem that although Alita did not respond to the tap on Page X by displaying page X+1, continuing to display Page X, it "believes" that Page X+1 has been displayed. Therefore when tapping a second time, it selectively erases Page X+1 (which is not displayed, resulting in ghosting), and then displays Page X+2. The result is of course an unreadable mess.

After restoring the display by invoking the screensaver and turning the Alita back on, Page X+2 is displayed, not the intended Page X+1, thus requiring a tap to the previous page before continuing with reading.

This bug is present in Alita's original Android 6, after the update to Android 8.1, and with all subsequent updates. It is intermittent, perhaps arising every hour or so.

I have stuck with Librera which hasn't given me any problems. It's easy to spend too much time fiddling around with these devices.

I think I asked this question already but forgot. When reading on Tachiyomi sometimes when I flip the page the page refreshes wrongly. Previous image stays there and it loads new one on top of it. Then if you flip to other pages parts of that first image still persist if that part doesn't need to be reloaded by the new image... the only solution is to flip back to the page when the refresh has gone wrong (it happens like every 20 page turns on average). Is this well known problem with Alita/Boyue devices?

Lol also it really like to freeze randomly when flipping pages and it's driving me insane (doesn't accept any input for a while and then skips two pages at once... it doesn't depend on resolution or file size of the cbz/image). I was thinking 8.1 will make all more smooth but I guess I was partly mistaken.

I have what seems to be the same problem, as detailed in one of my prior posts. I have provided screenshots to the Boyue Team on Facebook, and a sample PDF that I read when the issue arises, without however receiving any indication from the Boyue Team that a fix is in the works.

While using either KOreader or the Boyue reader, there is an occasional lag, followed by what I have determined is the failure to erase the current page N, before displaying page N+2 on top of it, "erasing" page N+1 which was never displayed - creating ghost images of page N+1. The problem has persisted through the 8.1 update, and all other updates, as in your case.

I have made the symptom less bothersome by being extremely careful about sending multiple or rapid page turn signals (rereading the page when there is lag, which in my case works because my reading material is impossibly difficult to understand on a first reading anyway), and whenever the corrupted display appears, hitting the power button to invoke the screensaver, and hitting it again to restore the screen. The screen usually displays the page after the one I intended, and in that case I have to tap to the previous page.

Boyue Team, if you are listening: Best wishes for a fix in the next update!
