Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. For Google Play services, first restart, check free space and update Android, Play system and Play services.
What this covers
- Google Play services with this exact failure state
- Diagnosis across one app versus system service update, account, storage and device certification
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. Expected behavior: provide account, notification, location and app APIs without excessive error loops.
Isolate the component boundary
ReversibleRestart, check free space and update Android, Play system and Play services. Use a known reference input or manufacturer test and compare the result. Boundary to separate: one app versus system service update, account, storage and device certification.
Correct only the proven cause
ReversibleClear cache before service data and re-add accounts only with credentials and sync verified. Correct the setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. Do not sideload system-service packages from untrusted sites.

Common follow-ups
What should I check first when Google Play services has this problem?+
Restart, check free space and update Android, Play system and Play services.
Why not factory-reset immediately?+
The useful boundary is one app versus system service update, account, storage and device certification. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not sideload system-service packages from untrusted sites.
