A phone or tablet producing an unexpected result — wrong location, wrong contact, wrong output — usually traces to a permission, default-app or account setting, not a defect. For Android default-app routing, first clear the current default for one action and choose the intended app once.
What this covers
- Android default-app routing with this exact failure state
- Diagnosis across system default versus in-app browser and domain-specific verified links
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleRecord exactly which permission, default app or account is active for the feature. Expected behavior: open links, calls, messages and files in the intended eligible app.
Isolate the component boundary
ReversibleClear the current default for one action and choose the intended app once. Test with a second account or a different default app assigned to the same action. Boundary to separate: system default versus in-app browser and domain-specific verified links.
Correct only the proven cause
ReversibleSet the supported default category and adjust verified-link handling. Correct the permission, default-app assignment or account setting proven by the comparison.
Verify and stop safely
ReversibleRepeat the original action and confirm the correct result with the fix in place. Do not clear app data when changing a default is sufficient.
