Debugging Crashes on Samsung and Xiaomi Devices

Your app works perfectly on the emulator but crashes on real devices? OEM-specific behavior is usually the culprit — and real tester feedback is the fastest way to pin it down.

The OEM Fragmentation Problem

Android optimizations by manufacturers like Xiaomi (MIUI) or Samsung (OneUI) often kill background services aggressively, causing crashes that don't happen on stock Android emulators.

Reading Tester Logs

When a tester reports a crash on AppTesterHub:

1. Check the Device Model in their report.
2. Look for "Battery Optimization" settings. Often, asking the user to disable battery optimization fixes 90% of background crashes.

Pro Tip

Use the Tester Chat feature to ask the specific user to run a debug build or share a screen recording of the crash. Direct access to real users is your best debugging tool.
