Android Compatibility Testing: Building a Smart Profile Matrix
How to select the right profile matrix for meaningful compatibility coverage.
A profile matrix should reflect real user distribution, not random device choices. Start with your top traffic segments by device model, OS version, and region. Add high-risk edge profiles for features sensitive to network or hardware differences. Keep the matrix lean enough to run frequently, but broad enough to catch regressions early. This balance gives practical coverage without bloating test cycles.
