Fingerprint Sensor Calibration: the big problem of the Galaxy A that remains unresolved

If you own a Samsung Galaxy A from the past two years, chances are you’ve encountered the dreaded ‘Fingerprint Sensor Calibration Required’ message. This article aims to address this widespread problem that has been reported extensively on the Samsung Spain forums. Unfortunately, as of now, there is no official fix announced.

The Problem with the Fingerprint Sensor

Users have been complaining about this issue for the past year across various models. The bug manifests itself when attempting to use the fingerprint sensor within any application. While it functions perfectly for unlocking the device, it fails to work in other scenarios, such as with banking applications.

Every user who has sought help on the Samsung Spain forum regarding this problem has left empty-handed. Forum moderators suggest remedies like performing a factory reset or enabling safe mode, but none of these seem to prevent the persistent appearance of the error message.

Even the common workaround of deleting registered fingerprints and re-registering them proves futile. When attempting to use the fingerprint sensor within an application, the error ‘Fingerprint Sensor Calibration Required’ continues to surface.

Samsung’s Suggested Solution: Contact Customer Service

The error message itself advises users to contact customer service if the problem persists. It appears that Samsung anticipates that this issue might linger for weeks if not addressed promptly.

Some users who have reached out to customer service have reported that Samsung doesn’t seem to allocate significant attention to this problem. In fact, one user shared that customer support informed them that the issue would be forwarded to their R&D department. This is rather perplexing considering it appears to be a known issue.

Evidently, this is a prevalent problem with Samsung Galaxy A devices, specifically with the fingerprint sensor when used within applications, as opposed to when unlocking the device. This might explain why it isn’t as widely recognized, as a substantial portion of users primarily utilize this component for device unlocking.

Given the lack of a definitive solution from Samsung, if you find yourself grappling with this problem, our recommendation is to reach out to the company’s support service to request a replacement or a viable solution.
