1P Android 8.12.42 frequent crash during scrolling down

I noticed 1P Android 8.12.42 frequently crashes when I try to scroll down.

Steps: Items tab → All items or one of Tags or Archive → Scroll down → App crash

  • It doesn’t look like a specific item triggers the crash as it crashes in multiple places.
  • No crash in Home and Watchtower tabs.
  • I cleared cache, tried sign-out and sign-in but no luck.
  • There is no issue with Mac 8.12.42.

I can open a support request and send a diag report if it helps.

Hello folks! 

I’m sorry that you ran into a crash when using 1Password for Android and weren’t able to use the app. This is an issue that our development team is aware of and has shed some light on here.

In short: a recent app update exposed a rare date-sorting bug that creates duplicate headers on the last day of certain months. That would explain why some people ran into the issue on October 31st but haven’t seen it since, a fix should ship in the next update to 1Password for Android to avoid the issue from happening in the future. 

If you’re currently seeing a crash when using 1Password for Android then please let me know and we can investigate further.

I have an android tablet + phone, after editing a 1password Login entry the following bug appears on both devices. This bug did not exist before. I changed the email address of a Login entry and afterwards this bug appeared.

 

 BUG DETAILS:
- I open 1password app and login into the “Home” screen. i can view, edit, create entries no problem. I can scroll no problem. 
- I click on “Items”, i can scroll up and down no problem.
- I can click into “Logins”, “Secure Notes”, “Credit Cards”, “Identities”, “Documents” without a crash. But AS SOON AS I SCROLL the whole app crashes (will try to attach logs below).
- This only seems to happen within my Personal vault. From Items->Personal (which includes Logins/SecureNotes/CreditCards/Identities/Documents above since those are in my Personal vault), any scrolling triggers the crash. From Items->Family, scrolling does NOT trigger a crash.
- SORTING within Personal using the icon at the top right does NOT trigger a crash UNLESS I sort by “Date Created”. 
- Uninstalling and reinstalling 1password does not fix the issue.


POSSIBLE ROOT CAUSE
The facts above, combined with the logs which start with 

java.lang.IllegalArgumentException: Key "header:OCTOBER 2026" was already used. If you are using LazyColumn/Row please make sure you provide a unique key for each item.


seems to point to some kind of Vault-specific data corruption when I edited the entry.


IMPACT
I am effectively unable to use my personal Vault due to this issue. While I could make a new Vault this could happen in that Vault too.

The fact that such a serious bug is possible and is not caught really erodes trust in the 1Password ecosystem… I’m a big fan of 1PW and would like to see this fixed ASAP. I hope info I provided is enough, thanks

    Update: Somehow the issue stopped since yesterday (no crash at all). Hmm...

        No more crash since my last update. Also got 1P update to 8.12.44 today.

        Thank you for the fix and hoping it would never recur.
