Occasionally, my fingerprint reader won't activate when my phone is locked. I put my finger over it, and the screen won't turn on - It doesn't even recognize my finger is there. When I turn the phone on, and put in my passcode, the fingerprint reader starts working again (apps like Robinhood). If I then lock the phone, the fingerprint reader starts working again. Over the course of a day however, it stops working numerous times and I have to put in a passcode to get the phone unlocked.
I'm using action launcher, but I don't have "double tap" to turn off power enabled...so not sure what it could be. Seems like its a software issue vs. hardware? I'm stock, no root.
Uninstall robinhood, it broke imprint in the last update
here is other thread already on topic

EDIT: dkotoric has realised this is due to using the double tap to sleep function on some launchers. Locking your device with that prevents the fingerprint scanner from allowing access for some reason.
So today was my first full day with the 6P. It's a truly great device.
A whole bunch of times though when I've come to unlock the device I've had to put in my pattern because it won't accept the fingerprint scanner.
The icon at the bottom of the lock screen that should be a fingerprint is just a lock symbol. If I then lock the phone again and reunlock it works as expected.
Not sure if this is a software bug or some setting I've got wrong. Can't see a pattern for when it does it though. I've switched 'require pattern on restart' off which has made no difference.

I've experienced that on one occasion today. That was after no occurrence in a full day's use yesterday. I put it down to slightly incorrect/incomplete/inaccurate finger print scans when it's set up.
Had no issues yet, used it for 2 days.
I have a pin set for after a reboot and it will ask for pin if I accidentally use pthe power button to switch on.
So far my finger print has not failed once o. My two index fingers.
I set up my finger print with a central / top end / bottom end / left edge / right edge and its worked fine
Been super accurate for me

I recommend using your main finger on different angles rather than using 5 different fingers when setting it up. ?

I've setup each index finger once and it hasn't skippes a beat. I'd setup your finger again and this time move your finger around after every press to get different angles.

I haven't had any issues whatsoever. You could setup each index finger as 2-3 different fingers if you want to improve accuracy too.
Still waiting on my 6P, but I do have the 5X. Installed all of my usual apps when I received the phone. Set up fingerprint scanner. For the life of me couldn't figure out what the heck was going on. Every time I would unlock the phone it would go to PIN screen. I had read all of the reviews on how fantastic the FPS was. Started to get really annoyed. In fact I did a factory reset to see if this would help. This time I didnt install apps just set up FPS. Worked flawlessly. Installed apps again and what do you know stopped working again. Then it hit me, I have an app called ScreenOFF. Basically I could touch the screen and it would turn the screen off without hitting the power button. Uninstalled app and FPS worked perfectly. SO, be careful if you have any of these types of app as it seems it screws up the ability to bypass lock screen
It seems to have sorted itself over night. Hasn't done it so far today. Thanks guys.

what I notice is I use lock app and apex launcher so I have it set up to double tap on screen to lock the device. If I lock the device using this method I can no longer unlock the device with my fingerprint. I have to use the lock pattern. Then I have to lock the phone again via power button in order to use fingerprint scanner?

Holy **** you're right yeah that's been my issue the whole time doing the same with Action Launcher. Been so used to using it it didn't occur to me that's the cause. That's annoying.

I have your issue but I am not using any sort of double tap to lock apps. also I am using google now launcher.
Yea this happens when you use a third party app or launcher to lock the device via a double tap on the home screen. I set up a gesture in Nova Launcher to lock the device via a double tap on the homescreen and when I do I cannot unlock the phone via Imprint. There is just a lock symbol instead of the Imprint symbol and the only way to unlock it is using the pin. It seems that right now the only way to use Imprint to unlock the device is when you lock the device using the power/sleep button. Using any 3rd party software without root access to lock the device will only let you unlock the device via the pin instead of Imprint.
EDIT: Everything works fine with root access. If you grant the app performing the screen lock root access then you will be able to lock the screen with say a gesture like double tapping the home screen and then you will still be able to unlock the device via Imprint.
I had this issue as well where my 6P would ask for my pin after using the fingerprint scanner. It would do this many times per day.
What I have found to stop this from happening is removing the administrator rights from all the apps that uses it to lock the screen. It seems that the phone will ask for a pin when a 3rd party app locks the screen.
So I'll just rely on Android locking the screen on its own vs entering the pin so many times a day along with the fingerprint scanner.

Are you just using nova as far as root access? I'm so used to just having greenify lock the screen, but I'm having this issue

I'm actually using loads of root apps including Greenify. (Though I'm not using greenify anymore) Everything is working fine. Are you having the issue when locking via a greenify gesture? I didn't even know Greenify had a screen locking gesture lol. Or do you mean the Imprint issue occurs after Greenify puts the device to sleep automatically?

Greenify has a widget that will hibernate and shut the screen off. I ended up finding this app that will shut the screen off and allow me to use the fingerprint to wake/unlock the device. :good:
So far, the only 3rd party app that I've found that can shut the screen off without root and without needing the pin again is Gravity Screen https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenofffree&hl=en
It has a few widgets that you can link your double tap homescreen gesture to. Specifically, I'm using Lightning Launcher and link the double tap to the "Off" shortcut. The other shortcuts will lock the phone and then you'll need the pin again instead of just the fingerprint.
However, I think the way this app accomplishes this is to first blank the screen off with just a black overlay and then set the screen timeout to around 10seconds (it sets it right back to whatever you had before by the time you wake the screen again). So far, I haven't had a problem with this since the app also has "in pocket protection" in which it will keep the screen from turning back on if the proximity sensor is covered. So if you double tap to sleep but then put it in your pocket before the 10 seconds is up, it won't turn it back on. If you have it sitting on your desk, you can double tap to sleep, but then tap again on the black screen within the first 10 seconds to see the navigation keys again. This also has the weird side effect of not being able to use the fingerprint reader during those 10 seconds, because technically the screen is still on. This was a little unsettling at first since I couldn't figure out why the fingerprint reader wasn't vibrating when I thought the screen was "off". To me, it's not that big of a deal so it's fine with me.
So, the 6P is a sodding big phone and I have fairly small hands.
Switching on to an unlocked state using the fingerprint reader is easy. Switching off requires the power button, which means wrestling the damn thing into a position where I can press the button.
I've looked at a few apps that switch off the screen with a shake or gesture, but these always result in a pattern request to unlock fully when turning back on with the fingerprint reader. Looking at this thread, it seems the Nova Launcher double-tap off function results in the same secondary security challenge when switching back on.
I assume this is because the third-party double-tap/shake/gesture event is only turning the screen off, not actually locking the device as the power button would.
Any ideas/solutions?
Use pocket lock and map the nova double tap gesture to the shortcut provided by pocket lock. There is some delay before it gets fully locked but it's the best option so far.

My Moto G5 Plus keeps locking whenever I’m making a phone call, and for some reason the fingerprint reader does not like to function more than 20% of the time when this happens. If I'm not making a phone call and am just waking the phone, the fingerprint reader works 90% of the time or more, usually only doesn't function if it's incredibly dirty or etc.
When I need to enter in information like when using an automated phone system that requires me to press buttons or I just simply want to hang up or alter settings such as turning on speaker phone, this gets in the way.
Is there a way to prevent the phone from locking only during phone calls? I don’t mind the screen going off but if it can’t be woken without using the fingerprint reader or with a button without entering my password, I’m not sure how I can get around this for phone calls that last longer than the lock screen timer.
Hi,
I am after some help please, preferably without reinstalling all over again (root etc).
If i leave my phone to lock after a few minutes of inactivity, the screen stops responding but everything else works:
All hardware buttons work
AOD - works, I can press notifications and the app opens, or hardpress the bottom home button to get to the home screen, but the screen wont respond after.
Fingerprint scanner - works, it bypasses the lock screen but nothing responds
DEX - phone completely responsive via keyboard and mouse
Soft reset - everything works until it has no activity again.
Safe mode - exactly the same, so seems not to be app related.
Just the screen wont respond after passing AOD but phone otherwise functional. Not dropped, no water damage - all good there.
Anyone gone through similar?
Cheers
Good lock 2018 - lock star
Interesting - after spending nearly all day playing about and deciding to post, i remembered there was a lockstar update for me this morning. I disabled the lock screen i built and the phone has been find since. I'll un-install and re-install it, and re-test should someone else have a problem with it and follow up.
Reinstalling LockStar fixed the problem. Case closed.
The OnePlus 6T's fingerprint sensor can easily be bypassed with this trick. . We have confirmed it working on two phones so far. Phone Unlocks itself via camera and voice from Lock screen, plz some one report..
Please confirm that the phone cannot see your face when you unlock it, and no Smart Lock trigger was active.
This alleged problem does not exist on my phone.

No i turned off face unlock , it just unlocks itself, just open the camera from lockscreen then close the camera app,
no , i turned off face unlock, it unlocks itself from launching camera from lockscreen thn closing the camera app, it bypasses all security locks " fingerprint , pins and face unlock"
We shall wait for others to check. I couldn't reproduce the error at all.
Do not have this problem with mine, are you sure you don't have your left thumb registered?

Either way if this is true. you should be reporting it to OnePlus. Not telling everyone on XDA how to break into someone elses 6T

So if I'm hearing you right, you're saying that by opening the camera from the lockscreen and then pressing your home button, your phone unlocks? Doesn't do that for me, it prompts me for my PIN or fingerprint when I press the home button. Can't reproduce this either... Might reinstall OOS? I'm at a loss for advice on this one.
I can reproduce this. I use navigation gestures, so opening the camera from the lockscreen and then just close it with the right (or left) swipe gesture to go back and you're in the phone. I don't think it has anything to do with the fingerprint sensor.
Edit: now I can't reproduce it anymore strange.. [emoji848]
I'm not able to reproduce this either. Switched to navigation gestures. Turned off face unlock. Launched camera from lock screen. Swipe from side to go back took me to lock screen with fp prompt only, no keypad for PIN. Tried again, this time swiping from middle to go home. I get fp prompt & keypad for PIN. However, with this screen the camera stays open and viewable through the lockscreen, but phone is still locked.
After a few tries I see my home screen but it's only a flash then it's back to my lock screen. It looks like it may want to but maybe I'm doing it wrong. Either way, this looks important enough to report to OP and see what's what.

Tilted phone so it can't capture my face and tried as you've said - running camera and voice commands from lockscreen and phone is still locked, cannot bypass..
So there are two vartiants.
1) Phone still recognizes your face
2) Enabled smart unlock? so phone knows that you are in home and automatically unlocks device.

Nope, i unlocked my friends mobile @ my home...
You sure you have a pin/fp/pattern set up at all?
I've been trying for 5 minutes with gestures and it always just either asks me for a pin or sends me back to the lock screen.
Seems odd but maybe post it on the OP forums instead of here, won't get them to fix it if they aren't aware of it...
Nope. Unable to reproduce.
