The mobile section of the Dashboard config displays widgets related to mobile data. These widgets display data only if you are using any of the PX mobile SDK. The Mobile Crash Events widget displays the number of times your application crashed during the selected timeframe.

I’m not aware of another way to surface those events in PX; they’re not surfaced in Query Builder

Thank you for you answer, from what i understand I can only see how many times the app crashed but not any details related to the stacktrace or any other useful information to help me with fixing those potential crashes.

How about in Audience Explorer? If you go to an individual user’s activity feed, and filter to include “app crashed” events, can you see more detail there?
