[Likebook Mimas and Muses] Notes app BUG that results in a loss of page data

[MustardOrMayo]

It seems that on Boyue Likebook e-readers with note-taking features, there is a serious bug in the Notes application, which is technically part of the home shell.

I'm posting it here as I don't think there are any official support channels besides contacting them through their AliExpress page. I can prove this bug exists on the 1.0.2 firmware, which is the current version on the Mimas as of posting this.

Basically, just open a note (and I recommend duplicating the page), then tap the "undo" button a few times, which completely erases the page! Now, if you're careful, you can tap Menu > Redo a few times, and get back the page.

I was able to do that a number of times, until yesterday, where I ended up losing a page and not being able to recover it, so I'm trying out using "Squid", which lacks e-paper support, but will have to do for now.

When undoing each step doe sit erase a little more of the page? or does it not do anything till you hit it a certain amount times then it's just gone?

The second one you mentioned, after opening a note.

In that case it sounds like it's an erase all command and does not always put the erased stuff in ram or depending on what it erases might be too much to store in ram to redo, they could fix it by making you have to hold the undo button for a while before erasing it all or perhaps even prompt if you want to clear all once you've held it down.

Yeah, I agree, and I think that's what Boyue should've done.
