App freezes

[suhlrich]

The app freezes during collection sometimes. The video on device screen freezes, and it stops pinging the server. Fine with close and restart. Any ideas @xhardcorex?

[xhardcorex]

I will investigate it

[xhardcorex]

Have someone faced this bug recently and could provide more details how to reproduce it? Unfortunately, I still can't reproduce it

[suhlrich]

It has been a few weeks since someone has told us about it. We will check.

The app froze for me today. Here's how it happened:

I had scanned a qr code, and after a few minutes, i got the "disable portrait mode" warning. The phone was oriented horizontally. I swiped up to see if portrait lock was on, and it was not. I then swiped up out of the app (did not close), then came back in. The "disable portrait mode" warning went away, but then the video viewfinder was frozen. I was able to press the gear, start a new session, and everything worked ok after that.

@suhlrich I have configured observer for tracking capture session errors which can help us to catch freeze error. Do I need to present alert with the error description for this case or maybe do you have API which can I use to send logs on the backend? Thanks!

Let’s just do an alert for now. Isn’t it possible when testing on TestFlight to send errors to the developer?

@xhardcorex - i got the app to freeze again today. I just stopped a recording and the viewfinder froze (it was also not uploading videos). Buttons were still working. Can we add a button to send logs when this happens? I did not get an alert on the device.

[suhlrich]

@xhardcorex, if we want to send logs to server, we can upload a txt file the same way we do a video. Get an S3 link, then post using same parameters as we do for a video.

Got it and will do. Now we have in the build 1.6(25) observer to catch this error and presents alert.

Thanks! Had the phones freeze this weekend, here is what I noticed.

1. we got something like 'AVCapture Runtime Error' several times. On many of these, if you closed the app and re-opened, you could not get the camera viewer (just a fully blue screen). You couldn't even use the native camera app. It's like the app died without releasing the AVCapture socket or something. Restarting phone solved it. I can't say this for sure, but I have not seen this type of freezing behavior happen prior to release 1.6(25), but I haven't stress tested (24).
2. sometimes it froze with no error shown. It looked like this happened when we stopped a recording (the person was still in frame)

[xhardcorex]

Could you please provide device model and iOS version of device you tested? Will you have a chance to record the screen(approximately for 10-15 seconds) when you stuck the freeze next time and share with me the video? Thanks!

[suhlrich]

It happened on these two devices:

iphone 12 Pro. ios 16.4.1 (20E252)
iphone 12. ios 16.4.1(a) (20E252)

And yes, next time I will take a video of the screen. Good idea.

@xhardcorex would it be possible to have a button on the error dialog that shows up that says "send error message to developers." when they press it, we upload to the database just like a video?

Let's not push this before this weekend (we have a big data collection over the weekend and I'd like to use a stable build), but if we could have it sometime next week, that'd be awesome!
