Hi @cmelchior,

A bunch of issues related to native crashes while using encryption are referenced in this merge request.

Can you elaborate on what is the issue and how will this help fix it. We can help out with testing it locally at our end if needed.

@mehulsutariya
You can see the details of the core issues and PR here. But it basically fixes one rootcause of corruption of encrypted files on Android specifically. Or it at least fixes some rootcauses for it. We are still investigating another potential race to see if that could be another cause of corruption and are therefore waiting on releasing this until that has been clarified during this week.
Do you have reproducible corruption cases using encryption? In that case it would be great if you can validate that it indeed fixes it. @cmelchior could provide a snapshot version perhaps?

Perhaps @vladimirfx would be able to validate as well?

[mehulsutariya]

Thanks for the details. We would be able to test it locally at our end on specific devices. If you can provide snapshot, that would help.

It would be awesome if it indeed fixes this issue as we are getting 1000s of such crashes on daily basis and looking at other issues in this project, many other users are facing this for a while now.

@cmelchior @bmunkholm We are still seeing the following crash after updating to snapshot version. Should I file a separate issue for this?

You can see the Crash Distribution by Device in the below screenshot. As previously shared in a related issue, Samsung dominates this issue more than any other device.

@mehulsutariya Yes please post a new issue with the complete crash info.
Thanks!

[bmunkholm]

Also, please use the released version. Snapshot version is undefined. We don't know which specific version you have used.

[mehulsutariya]

We are using 6.1.0-SNAPSHOT

A SNAPSHOT version can change - depending on when you take it. So it's never a well defined version.
