The fingerprint scanner on Google’s two new Nexus devices are amazing and fast. They’re right where an index finger naturally rests, making unlocking the phone natural and fast. It’s extremely easy to use, setup, and enjoy. My own Nexus 6P has no problems, and works nearly every time even months later, but that isn’t the case for everyone.

Nexus 6P Fingerprint Scanner Tips & Tricks

If your Nexus 6P fails to recognize a saved fingerprint it could be caused by a few different things. Below we’ll go through them all, the proper way to set up and insert your fingerprint, and a few other steps to avoid problems.

First up, if you’ve already added a fingerprint or two, make sure the scanner surface is clean, as it may not be getting an accurate reading. Dirt, pocket lint, fingerprint oil build-up and more could be causing it to malfunction and not get a 100% accurate reading.

However, the biggest thing is how you setup your fingerprint. The setup is pretty self explanatory, but also requires less taps than Samsung devices, so you must get all 6-8 of them right. If you didn’t do it perfect, you may want to delete them and redo each saved fingerprint. In the video below we’ve fast forward to entering a fingerprint, and it’s a good example of doing different angles, sides, areas, flat end or the tip of your finger.

Those having problems with it not being accurate and failing to read a finger, delete it and try again. Simply head to settings > security > Nexus imprint > Confirm Pin then add more, or tap and either rename or “Delete” the currently saved scans. Now just add it again, and take it slow, make it accurate, and make sure the scanner and fingers are clean.

Some forum members claim doubling the same finger in the system for a better chance of success, but this just makes the system more confused, so we’d recommend only doing one entry for each finger. Google claimed its system learns the “imprint” over time and gets better, so we’d only recommend deleting it if you’re truly experiencing a lot of issues.

So what could be causing problems? A case. If you’ve recently added a new case to the Nexus 6P the angle may be slightly different, causing issues with the scanner. I’m not experiencing this with the official case, but I also re-scanned and saved my imprint after I added the case. So some should try that as well. Here’s the instructions one more time just in case.

  1.  Head to Settings > Security
  2. Tap on Nexus Imprint
  3. Hit Continue, setup a backup password, pin, or pattern
  4. Follow the steps, tap the scanner 6 times, to save a fingerprint
  5. Once finished add more fingers, or one from your other hand
  6. Nexus Imprint learns as you use it, and becomes more accurate over time

We’d recommend users setup both index fingers, as that makes the most sense, then add more if you’d like. Again, keep the case on if you use a case, and make sure fingers and the surface are clean.

Most users are enjoying the scanner without any issues whatsoever, but those who are having trouble should try deleting them and starting over using all of the information provided above. If things still aren’t working right we’d suggest maybe buying a different case, or doing a factory data reset (which will erase everything) and starting over completely. That is a last resort.
