New ANRs or crashes are not necessarily attack signals. Examine device cohorts, threads and SDK interactions to find the cause.
Evaluation approach
Compare stack traces, versions and device groups. Investigate main-thread blocking, locks and native-library compatibility.
Application example
A crash before a security event should be tracked as a technical defect rather than reported as a successful block.
Limits and considerations
Events increasing in the same release does not by itself prove causation.
Separate rejection from application failure
Expected transaction denial, crashes and Android ANRs are different outcomes. Even intentional termination can disrupt users, so define acceptance criteria in advance.
Associate crash reports with application and protection versions. Correct symbols or mapping files support diagnosis. Segment post-rule increases by device and flow before labeling them a general platform problem.
Checks and decisions
- Match symbol files
- Reproduce conditions
- Use controlled comparisons
Restored user experience and verified protection are separate acceptance criteria.
