Android app truncate large (multi-gigabyte) files during camera upload

[4ndr3aR]

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:

sorry to bother you again and again,

No bother, it's good you report any bugs and hopefully we fix them or solve them.

but on the server the file is only 1.1 Gb

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).

this PR should fix it

[zerox80]

@4ndr3aR can you give it a test and say if it gives u any issues ?

[zerox80]

@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

Hi @zerox80, my phone is an OnePlus 6T with Android 11 (OxygenOS 11) and the app version I'm running is 1.2.3.

@4ndr3aR can you give it a test and say if it gives u any issues ?

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.

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 :)
