The fingerprint scanner is one of the top three features on my Nexus 6P. Unlocking your phone is one of the most trivial tasks we can do, and we do it hundreds of times every day; having to just touch the fingerprint scanner is not going to save you hours in a week, but it definitely is one of those "quality of life" improvements that we quickly grow fond of. What I found though was that the fingerprint scanner on the Nexus 6P isn't perfect. On average, a quarter of the times I was trying to unlock my phone it just didn't work. I initially thought this was a problem because I'd just set up my fingerprints and the system needed some time to adjust to all the different angles I was using to unlock my phone. But as I used the phone more and more I saw no improvement. So I figured out a neat workaround. It's a workaround and not a fix, and you'll see why in just a minute. To set things up you have to open up the Settings menu on your Nexus device and go to the Security tab. Once there, go to Nexus Imprint - this is the control center for the fingerprints that Android recognizes. As you can see in the image above, there are five fingerprint slots. The trick to getting better results is to remove the five fingers you presumably have set up and re-add them, only this time use just two fingers. I entered both my index fingers twice (since they're the most likely to be used to unlock the phone), and since I had one fingerprint left over I used it for one of my thumbs. The result? I'm at 100% unlock rate, and when using my index fingers I never had the phone refuse to unlock or ask me to try again (unless I moved my finger too fast, but that's a user error). So while it takes two fingers away from your list of choices, this method makes up for it with accuracy.
What's my model number?
There are several ways to locate your model number:
- Option 1
- On your device, go to Settings, then "About device" and scroll down to "Model number"
- Option 2
- Often times you can view the model number inside the device, by removing the battery
- Option 3
- Using Samsung's model/serial number location tool
