Guide / 01
What the answer means for this product
Face recognition depends on the phone camera seeing your face; fingerprint access depends on the phone’s sensor location. The zipped pocket does not change those device requirements.

A useful next check
Check your phone’s unlocking method and test it while stationary. Do not rely on an unverified pocket opening for biometric access.
