  • The first reason is, in case you have a physical reader, it is because of the dirt. Sometimes when we press the fingerprint reader, many times it tends to leave a mark and, as a consequence, it is usually inaccurate.
  • Another detail that you should not lose sight of is that your finger can also be dirty. Sometimes fingerprints tend to store dust that we often don’t see with the naked eye.
  • The most recurrent is that you pick up the cell phone with sweat or with a wet hand. This will also cause a layer to form on top of the fingerprint and not be recognized as such by the smartphone.
