You could a tool like LogDog

This allows to capture all logs and network requests from your app wirelessly.
I needs to be integrated once and then captures everything you need to reproduce.

If you no longer need the logs it is possible to turn off the SDK remotely (no code changes or a new build required)

Can help to catch these annoying bugs that only happen on users devices but never on developer machines :)

Note: I build LogDog exactly for these use cases.
