Android app freezing after launch

[matejkramny]

The bug

The android app freezes shortly after launching, every time. Perhaps I have too big of a library.. web works fine. The app logs don't show anything useful.

I have tested the demo server, and it works fine. Library is ~70k photos. Another user on my server has ~10k photos - works without issue.

Have had an external library but removed since, don't think it's a duplicate of #8148 but is very similar.

How can I best figure out what's wrong?

Reproduction steps

1. Have big library
2. open android client (logged in already)
3. App is interactive for ~10s
4. App freezes, perhaps for ~30s
5. Becomes responsive again but then freezes forever
6. Backgrounding and opening app then shows black screen (flutter crashed perhaps)
...

Relevant log output

I can't find any relevant logs in the app
Have enabled more verbose + diagnostics. No logs after the black screen

Additional information

The top user is not working, bottom one has no problems

Can you try accessing your instance over local IP? What is your mobile phone model?

[matejkramny]

Hi, I can't as it's a dedicated server in another country. Using pixel 2 (android 11). It's understandably not the best in today's performance but it works just fine with 10k photos user

[Mikesco3]

I'm having the same issue. My server is within my local network, I'm accessing it using the local static IP.

I'm running a galaxy S21+

But it seems to be the issue with my android app version 1.106.3 build 14.3

Server version 1.106.4 on a Debian 12 container.

The experience is that:

1. Open the app
2. If I scroll a bit or try to play a video, then at around 30 seconds into it, the app freezes and doesn't respond to anything, except if I hit the button on my phone to switch to another app, (not even backing all the way out to another app, just enough to show me the carousel of other running apps) and then go back to Immich then it might snap out of it after about a 3-5 second blank screen but about 10 - 30 seconds later lock up again.
3. But most of the time I can only get it back by closing Immich and starting again.

I've tried running it in various conditions: Closing all other apps Rebooting the phone But same result, seems to be pretty consistent.

It feels like it locks up trying to index or cash the content.

I also very large library. Also the app doesn't tell me anymore how many total items...

Let me know how else I can help. Thank you for such an awesome app!! Look Forward to contributing and paying some

[matejkramny]

I'm going to try to attach adb to the app loaded on my phone and will see what's locking it up later this week. Can't reproduce the hanging in the emulators but I'm suspecting it's writing a lot of data to the database?

[matejkramny]

I wonder if it would be worth implementing this usage pattern, if not already - https://isar.dev/recipes/multi_isolate.html#example

I found isolate usage in the code but it might be for the background sync. I'm thinking if doing the database sync in an isolate thread would help with performance. For a large library I imagine 70k record updates would take a while whilst it freezes the UI thread

[matejkramny]

Hi,

I found using isolates helped, adb logs don't show any more than usual, other than using CPU profiling which shows Isar doing this:

The UI locks up at this state, and there are no more logs.

Doing more CPU profiling shows about the same things, maybe as flutter itself stops responding on the app. It's possible something crashes, but I'm at a loss as to how to debug it any further because there are no logs in addition to what I screenshotted.

As I mentioned, running the app with my isolate PR fixes this problem, but I suspect it might be something related to it, or a side effect/bug that I put in f.e. - there are watchers on the Isar db that would refresh the UI. Perhaps this happens too many times (per asset?) and that might/not be happening with the assets synced in the isolate?

Thank you!

We‘re experiencing the same on my wife’s Galaxy S20, see here: https://github.com/immich-app/immich/discussions/9614 No problem on my iPhone

I hope your PR can be merged at some point. For us, this is the most annoying bug with this otherwise amazing software. I understood it might not be the root cause, but maybe it improves things. I am clutching at every straw 🤣

Hey!

I've implemented immich locally for a month now. Everthing has being going great up until a few days ago? For some reason the App opens, I can see the thumbnails loading and then It just hangs, can't scroll ou access the menus.

Android App version: 1.115.0 Immich version (updated today): v1.115.0 Phone: Samsung A53 5G

I've tried clearing cache: same behaviour. I've proceeded clearing data. This required me to login again and setup automatic backup. So far the app is working, will report back if not.

[LinhyCZ]

This is unfortunately also happening to me for couple of versions.. Background sync works, but after few (approximately 20) seconds the app freezes and I cannot do anything. Does not matter if I open gallery or sync settings, or other screen. If I tab out and return to app, I only see black screen.

Immich version (both app and server): 1.115.0 Phone: Huawei Mate 10 Pro

[alextran1502]

@LinhyCZ how many assets do you have on your instance and local device? How many album do you have on your Immich instance? How long have you been installing the app?

[matejkramny]

@alextran1502 is there a good way to get library stats? I've made a dummy user with 100k photos and the app worked just fine. My library is ~70k + some videos

Also tested on pixel 2 when i made this issue (100% of the time), now got a pixel 8 pro - still having the same problem just not as frequently

[alextran1502]

@matejkramny the easiest way is from the web, you can hover on the icon next to the navigation button to show how many assets/albums the user has. I believe the bottleneck is our albums synchronization code that competes with the UI thread. We discussed internally and come up with a better solution. The PRs you are seeing that refactoring the mobile app are steps toward solving this issue

[LinhyCZ]

@alextran1502 I have about 24k photos and 2k videos + 10k assests from external library. I have been using Immich for almost a year (I think :D), about two months ago I noticed some assets were not uploaded, so I uninstalled the app, installed it again and reran the upload job (which fixed the missing assets).

[alextran1502]

@LinhyCZ thanks for the info. How many Immich's albums and albums on the local device do you have?

[LinhyCZ]

@alextran1502 I only clicked on the Recent option, I don't have any albums created..

[LinhyCZ]

@alextran1502 I have tried working with the app a bit more, uninstalled it and installed it back again and it is somewhat working, but the reactions are very slow.. sometimes it takes about 30 seconds until the app registers i clicked on something or renders something..

[alextran1502]

@LinhyCZ We are working toward a better sync operation, which will make the app more responsive when first opening. By the way, what is your phone model?

[LinhyCZ]

@alextran1502 Might make it better, but this is not just on a first opening. For me the app is very sluggish the whole time I use it.

My phone is an old Huawei Mate 10 Pro.

[yewkay]

I have 63k photos and I'm experiencing the same app hang/crash issue. Background sync works but if I open the app, it will crash shortly.

Opening in webui will works fine for me
