Hi @juristat;

I would like effectively more info since it also happen on my new phone and I had previously opened an issue for the same kind of behavior.

My new phone is an Samsung Galaxy S8 (SM-G950F) "dreamlte" with Android Pie (9) I have the same issue with the Bitwarden app version 2.6.1.

Previously I opened this issue but it was for a different phone.

The same happens on a Samsung Galaxy J4 (2018). The camera viewfinder is somewhat narrower and the app crashes when it sees the QR code.

Similar reports from bitwarden/mobile#1289:

Device: Google Pixel 3
Operating system: Android 11 RQ1A.210205.004
Build Version (go to "Settings" → "About" in the app): 2.8.0 (3349)
Is this a Beta release? No

I have the same issue. It seems to only happen on 'complex' QR codes.

My workaround is to use Google Lens to get the URL from the QR, and paste the URL in Bitwarden.

It appears that I've got the same issue:

Device: Galaxy XCover 5 - SM-G525F/DS
OS: Android 11
Build Version: 2.9.1

I have the same issue. It seems to only happen on 'complex' QR codes.

My workaround is to use Google Lens to get the URL from the QR, and paste the URL in Bitwarden.

I've never found one that cant be scanned in my case it just takes multiple attempts.
The complexity doesn't seem to matter in my case, its truly random as far as I can tell.

I have never been able to scan a QR code from within the bitwarden app, it crashes on both official and custom roms (Android 7/8/9/10 all basd on Samsung oneui on my Galaxy S7 G930-F. The only time I did got it to work was when I used an AOSP based rom ( Android 9).

I just use a seperate QR code scanning app and copy / paste the url into the Bitwarden apps TOTP field to get it it to work.

I've tried to better understand what causes this, to make adding 2FA less of a hassle and hopefully help whoever looks into this in the future. But even testing different methods in different circumstances many times didn't lead me to any clear conclusion. A previous version of this comment said it did, which recently proved false upon further testing. I apologize for that, this is confusing.

Thanks everyone for the info! We weren't able to replicate this in multiple devices but we suspect the linked PR changes will fix it. If you previously had this issue, can you download the .apk from our CI and test it please?

Obligatory disclaimer: This isn't an official release that went through regression testing, there might be other unrelated issues overall, we just want to be sure this TOTP crash is fixed.

Issue was automatically closed due to being linked in the PR but I'm reopening this until we figure it out.

Edit: Updated the CI link

The issue I'm getting happens the second time I try to scan a QR code without restarting the app. The crash message is java.lang.RuntimeException: Camera is being used after Camera.release() was called.

[Larry-Sussman]

This has been addressed by bitwarden/mobile#1759 and should be resolved in the mobile app v2.16.2. Please let us know if this crash still occurs after this update. I'm leaving this issue open as @vvolkgang mentioned until we can confirm the fix.

[aouerf]

I thought that I installed the update before reporting, but I guess not; this was a mistake on my part. After updating and testing, I can confirm that the latest build fixed the issue for me.

[fmbarina]

Happy to see progress on this, but sadly it still occasionally crashes here. Adb logcat also shows java.lang.RuntimeException: Camera is being used after Camera.release() was called.

Device: Asus Zenphone 3 Zoom (ZE553KL)
Operating system: Android 8
Build Version 2.16.2 (4334)

[vvolkgang]

@fmbarina can you provide reproduction steps? We believe that's a different issue and we've been unable to replicate it yet.

[fmbarina]

I wish I could provide more helpful information - and do tell me if I'm doing this wrong. But I just...

1. Open bitwarden app (after restarting phone just to be safe)
2. Add new item (tap + icon)
3. Tap scan button with camera already pointed at a generic test QR code

• secret = SY3SJKJCWOFJQC6XHIP5RWWYV4DQNGQE
• label = Label
• issuer = Issuer

And upon trying to scan, sometimes it crashes.
I'm willing to try to reproduce the issue with other tools if that'd be any help, I just don't know what those would be.

[kosmoz]

I am also experiencing this issue.

The camera works fine until it "sees" the QR code, then the app crashes.

(2.16.2 on Xiaomi Mi5s running LineageOS 16, Android 9)

[Greenderella]

This issue appears to still be present on version 2.18.0

[develop7]

I'm affected by the issue as well, version 2022.05.0 on Pixel 5 running Android 12 (security update May 5, 2022). Bitwarden app crashes on first attempt to scan the QR code; scanning the code after reopening the app after crash succeeds though.

[fedemkr]

Thanks a lot for all the feedback, this is happening because of a racing issue so it's quite difficult to reproduce consistently, but a fix has been applied in #1942 and will be available in June's release. Please let us know if this keeps happening after the release, thanks.

[develop7]

@fedemkr any beta releases before that?

[fedemkr]

Hi, @develop7 you can grab the apk from Github Action Artifacts and try it to see if that solves your issue but beware that the app may not be stable given that it's a development build and it hasn't been tested thoroughly by the test team yet.
Also, we're going to ship it to the beta channel before the final June release so you can wait for that as well to have more things included and better stability (just in case here also applies that it's not the final release so issues may appear during beta testing but much less than development build)
