Android app truncate large (multi-gigabyte) files during camera upload #181
Description
Hey folks,
sorry to bother you again and again, but I found another possible bug in the camera upload process. I was trying to upload a 5.4 Gb video, the app reported that everything went ok, but on the server the file is only 1.1 Gb. Here is the app log:

No bother, it's good you report any bugs and hopefully we fix them or solve them.
TUS: upload completed for /InstantUpload//VID_20260531_204548.mp4 (size=1180123136)is actually that size.Is this for a video file that is uploaded while it's not completely written yet to the phone storage?

Shouldn't be the case. The logs say the upload started at 2026-06-01 23:51, so more than 24 hours after I finished recording the video (started recording at 20:45 of 2026-05-31 and it's a 20 minutes video).

is the suspect commit for this bug
this PR should fix it
zerox80 commentedon Jun 4, 2026
@4ndr3aR can you give it a test and say if it gives u any issues ?
zerox80 commentedon Jun 4, 2026
@4ndr3aR can u say which android are u using? Which phone? this bug just seems like your android system is very aggressive with background workers and kills it randomly, thats a very very edge-case bug
4ndr3aR commentedon Jun 4, 2026
Hi @zerox80, my phone is an OnePlus 6T with Android 11 (OxygenOS 11) and the app version I'm running is 1.2.3.
Should I upgrade to the latest version in the play store? I don't see any updates at the moment, the last update on the play store is still from 19/05.
zerox80 commentedon Jun 4, 2026
Nono try running my PR, are u able to compile it? we can run a CI for building the apk
4ndr3aR commentedon Jun 4, 2026
With t→∞, probably yes, but if you want a response within a couple of days, it's better if you run a build for me please :)
guruz commentedon Jun 8, 2026
I will do a QA build for you, i'll ping you about it.
guruz commentedon Jun 12, 2026
Looks like Google approed v.1.2.4. in Play Store open testing track?
4ndr3aR commentedon Jun 12, 2026
You're right, I'm updating right now. What happens if I just
touchthat 5.4 Gb video under Android Termux? Does changing its date make the app attempt a re-upload? Or I'll have to rename it to something else to make it appear a new file in the app DB?Checksums: Also get them via PROPFIND
guruz commentedon Aug 11, 2026
Sorry for late reply. Did you have any good or bad news about this issue?
4ndr3aR commentedon Aug 11, 2026
Hey, no problem at all, I kept testing all the time :)
All in all I'd say "mostly good". The large 5.4 Gb video failed to transfer even after renaming, but after that, I see that I only have another "large file" in
opencloud/opencloud-data/storage/users/uploads, a 1.3 Gb video file namedfd50a622-5469-4912-94d8-8c83822c9fed, but other files with comparable size transferred (and showed up inInstantUpload/Camera) without problems.Looking at the logs, it seems my docker is literally spamming messages like this one:
{"level":"error","service":"proxy","error":"failed to verify access token: token has invalid claims: token is expired","authenticator":"oidc","path":"/graph/v1.0/me/photo/$value","user_agent":"Mozilla/5.0 (Android) OpenCloud-android/1.2.5","client.address":"","network.peer.address":"IP_addr","network.peer.port":"PORT","time":"2026-08-11T13:26:15Z","message":"failed to authenticate the request"}But the app isn't complaining and it seems to upload files "almost normally". Maybe it's better if I re-authenticate, right? Should I delete my user on the app or is there a faster way?
