My phone's fingerprint scanner is a hit and miss.
It sometimes does not responds to my finger input.

Would appreciate some thoughts on this:
I like using an app to lock my phone, and I have this one installed:
https://play.google.com/store/apps/details?id=com.iglint.android.screenlock
It locks the screen, but I notice that the Nexus 6p will not allow me to wake the phone via the fingerprint sensor.
If I use the app to lock the screen, and then use the fingerprint sensor, the phone prompts me to enter my pin.
If I use the power button to lock the screen, the fingerprint sensor works as intended.
Thoughts?
My thoughts would be that this app has not been updated to include fingerprint sensors to be able to unlock.
Once it does that, I assume it would work.
Either that or only an official method of locking the screen can allow your fingerprint to unlock.

Screen Off and Lock Apps break Nexus Imprint

i would love to be able to turn the screen off and lock with the fingerprint scanner. hence - we would never have to touch the power button.
Hey guys
Every time I use finger print to open my phone it always ask for PIN straight after, how do I turn off the PIN I just want to use finger print to open my phone? Thanks
If it's asking for the pin after you use the finger print without ever unlocking the screen first then it's not recognizing your finger print.
Are you locking it with double tap on nova prime or with the screen timing out? Those both force the PIN for me.
Using the power button to lock, the fingerprint works every time
I know Marshmallow does a lot of wakelock/alarm optimizing on its own, but I like to run Amplify not just to extend my battery, but also for privacy reasons - I block a lot of services with things like "analytics" in the names. I got my new Nexus 6P today and while getting everything set up, I noticed that somewhere along the line the fingerprint scanner had stopped waking the device - I'd put my finger on it, get the single vibration, but the screen wouldn't turn on. I'd have to hit the power button as well. (Oddly enough, if I did the fingerprint and then the power button, it would unlock immediately on waking, so the fingerprint scanner was clearly registering the fingerprint, it just wasn't able to actually wake the device.)
I managed to narrow this down to being Amplify's fault somehow; with Amplify disabled and no other changes, the fingerprint scanner works as expected (wakes and unlocks the device in one press), but with Amplify enabled, even without any services, wakelocks, or alarms actually blocked, the fingerprint scanner won't wake the device. Has anyone encountered this? Any fixes?
I just picked up my 10 after having an S7 for a while and I really like it. One thing that I'm still confused about is the fingerprint sensor. I have a pattern setup along with my prints. If I leave then phone for a while and press my finger on the pad I'm asked to input the pattern. Then once I do I can unlock then phone with any finger by just pressing the home button.
It seems to defeat the purpose of having a fingerprint sensor if it always prompts me for my swipe pattern.
Am I missing something in how I have it setup?
I know after a reboot you have to enter your password/pattern/pin each time but I do experience the same thing you do but it's pretty rare though. Long periods of inactivity doesn't cause it on my end, it just happens from time to time. Maybe it's some kind of security feature that after so many unlocks with the fingerprint scanner that a password authentication is required. Kind of hard to steal someones fingerprint but it is possible if you know what you're doing, where as brute force cracking would take much longer and triggers a factory reset after 10 attempts. Think of it as an alternating form of two factor authentication just to make sure it's you that is in possession of the phone. Just a guess though.
Yeah I've been trying a ton of different things and nothing seems to be working. Sucks!!

A couple of times since I've had the 6T, when I tapped the screen to bring up the ambient display or lock screen the fingerprint sensor wouldn't be active. The fingerprint icon would be white and putting a finger on it did nothing. The first time it happened, I was using the single tap to ambient display. When the fingerprint sensor didn't work, I hit the power button to bring up the lock screen and the sensor activated and I was able to unlock using a fingerprint.
I've switched to using double tap to lock screen with both face & fingerprint unlock. Tonight when I tapped the screen the lock screen came up but again the fingerprint icon was white, not active, and face unlock didn't even work. I had to swipe up to unlock with my PIN. After doing so, both fingerprint & face unlock have worked as normal.
Any ideas on why this could be happening? Just a random software glitch? Or does device security require unlocking with a PIN/Password/Pattern after so many fingerprint/face unlocks or after a given amount of time?
yes, it happened to me as well.
but i dont think this is a bug/glitch. This happened to me on other android phones as well.
i think this is a security thing where your fingerprint sensor/ face id is disabled once in a while and you can only sign in with your pin/password.
