Stops responding when editing a large note on Android

[da2x]

Environment

Joplin version: 1.0.312 Platform: Android OS specifcs: 10, Samsung S10e

Steps To Reproduce

1. Create a new note and quickly type a 4000+ character note in one go

The app stops responding and text input no longer appears on screen. If you the problemt and continue typing, eventually the on-screen keyboard will also stop giving visual indications as to what letters you press. The whole system becomes unresponsive. Wait up to 10 seconds and the app will catch up with what you've typed and recover.

After the app has lagged behind input once, the app will be slow to respond to all subsequent text input. You can temporarily work around the issue by quitting the app and editing the same note. Text editing will then be fast for a short while. After some time, the issue reappears and text input becomes low and unresponsive again.

I see this quite often, also.

@da2x I have a series of questions for you and things for you to try:

1. When was the last time you restarted your phone?
2. When was the last time you went to Settings->System Updates->Download and install to see if there are new updates for your phone from Samsung?
3. When was the last time you went to Settings->Device Care->Memory and ran Clean Now (to stop background apps you're not using that may be hogging valuable resources)?
4. What launcher (Home UI) are you currently using?
5. Have you uninstalled and reinstalled Joplin from the Play Store?
6. How do you type a 4000+ note in one go without your thumbs getting tired? O.o

Might be related to #2357.

I am experiencing the same problem. Whenever the keyboard starts to lag after working in Joplin for some time I clear the data of the keyboard I am using(Gboard) from the Settings. This fixes the issue. A workaround for the problem is to use NeutriNote app on Android to write notes in markdown and then share it to Joplin or copy-paste the markdown code.

I believe this is the same issue as #1493; it's an issue with React Native itself (to be potentially fixed in v0.62)

It’s still a problem with the most recent version.

[virtadpt]

The problem seems to be in an upstream JS library. There's a thread on the forums about it.

tl;dr - Android is a no-go until that gets fixed.

Closing this issue after a prolonged period of inactivity. If this issue is still present in the latest release, please feel free to create a new issue with up-to-date information.

[da2x]

Still an issue.

[thearchivalone]

Reopening due to bug still showing up. Anyone have any thoughts on how to solve this?

[shreyasbharath]

Still a major issue, app is unusable if notes are large enough.

VERY slow on editing quite large notes on Android.

I'm experiencing same issue. After writing even less than hundred words (into the new note), app starts being unresponsive, than keyboard lags until couple of seconds, when it catches up. Eventually i have to leave editing mode. And enter it again.

Thanks

That one mentions React Native-version, which currently is 0.59 or 0.59.5, found in packages/app-mobile/package-lock.json:

Solution for me was to opt-in to new editor beta

I have the same issue. As a temporary solution, I am switching from Microsoft SwiftKey keyboard. to Gboard while note starts to become laggy. That makes I can finish typing my note : ) but anyway still annoying bug.

I was experiencing what i believe is this same issue. I open a note that isn't very large (maybe 35 lines), and as I type things go slower in what appears to be an exponential progression.

I tried switching from the 2.8.1 release to the new 2.10 release (released today) and the same thing occurred. Since the editor has been rewritten, I figured it must be something else. My phone is also a Samsung (S21 FE) like the original reporter.

On a whim, I switched the keyboard from the Samsung keyboard to GBoard, and presto, no slowdown. Switch back, and it slows down again. So it is, in my case, some interaction with the keyboard.

It also seems that I can append some information to the note without a slowdown, but inserting information in to the note takes only a handful of characters to become unusable. Inserting one character, then appending to the end of the note seems to continue the exponential slowdown.

To escape from the slowdown I need only exit editing the note and re-enter editing the note.

I hope this helps.

This is fixed since the switch to CodeMirror
