Hi @SamSG,

Sorry to hear you’re seeing this crash. Are you able to reproduce this locally at all, or is it only something you’ve observed in production? If you can reproduce locally, please provide steps to reproduce so that we can investigate further. In the meantime I’ll also see if we can figure out any solutions based on the stack trace alone.

Thanks!

Hi @SamSG,

After looking into this further, I don’t think we’ll need reproduction steps from you. We found that this is an Android OS error which was resolved in Android 6. More information can be found [here](https://issuetracker.google.com/issues/129894679?pli=1). Since 99% of your users who are seeing this crash are on Android 5, it seems extremely like that this is the cause of the crash.

Thanks!
