Task 02 · Q789 Android compatibility
Check compatibility signals
Read the Android version and system error instead of guessing from the phone model alone.
APK source and compatibility only; browser-session login has its own diagnostic site.
Three-pass method
Make the result reproducible
-
1
Observe before changing anything
Open the current Q789 route and note the exact point where the task begins. Keep the host, time and visible label together.
-
2
Change one variable
Test only one of network, device state or route at a time. Multiple simultaneous changes make the Q789 result impossible to interpret.
-
3
Stop and record the result
If the route asks for an unrelated secret, repeats without completing or contradicts the expected task, stop. Save only non-private evidence.
