Weird Fingerprint Bug - OnePlus 5 Questions & Answers

For the fun sake, i tried my unregistered fingers with the fingerprint reader and in like 4-5 attempts, the device got unlocked even with unregistered fingerprint.
And when it did not get unlocked and the screen started displaying "Too many incorrect attempts, try again later" , unlocking the device was as easy as pressing the power button and swiping the homescreen.
Did anyone noticed the same behaviour?

HTC HD2 Unlock problems

Hi,
I have owned my HTC HD2 for about 3 months now. I have had a problem since i first got it which is really bugging me. Sometimes when the phone locks, i am unable to unlock it with the slider. The slider gets to about half way across the screen and then freezes. If i leave it for a few minutes it goes back to a locked position agian and when i attempt to slide the slider across, it freezes.
The only thing which gives me access to my phone again is to perform a hard reset by removing the battery.
Any ideas? The phone is on UK Vodafone and is running the latest firmware (v.1.72)

I don't have an answer, its likely to be sense trying to load something and hanging.there are loads of threads about unlock problems, all different, however I wanted to help you avoid confusion by pointing out that removing the battery is a soft reset, not a hard reset.
I'd start by removing some apps, see if it changes the behavior, then re add til it happens
i've the same issue. but not removing battery, just press little red restard button uder battery cover. i think it happens when i enable rotation of today screen or because of proximatelyscreenoff program bug. after removing today from rotation of bsd tweek i have 1-2 restarts for 2 weeks.
I had the same thing sometimes, but never happened with the latest rom I am using, and I am pretty much installing the same apps over and over after each flash...
You aren't by chance running the facebook application?
Leaving that open and locking your phone will result in you not being able to unlock your phone
I wonder if this problem has anything to do with power supply; I sometimes can't unlock the screen either and a few moments ago my battery had run out and when putting it on AC I wasn't able to unlock it. When it had charged a bit there were no problems unlocking it.

As I said, have you tried making sure Facebook isn't running
HD2 screen unlock probblem
Hi All,
I have put my screen unlock code as 0000 and set as 5 mins to lock the phone.
But that is becoming a headache now.
Sometime the phone behaves very unusual, it doesn't takes my code "0000", no option rather to reset the phone or remove battery and restart.
After the reset the phone works with my code (0000) but don't know when the same problem starts again.
Need Help..
Anyone solved this problem?
In the Att Tilt2 the power button was on Top & could close the Screen while talking on the phone
How do we do that in the HD2 cos its Off button is on the Red Call Shut button
Anyone
Unlock Problem
I everybody,
I have this issue aswell but even worse than everyone else. I can't unlock my device at all anymore else I do the "hold both VolUp&Down + Power Button " for reset to manufacturing settings of the cracked ROM.
any process so far or do you guys still think it's about messed up Apps?
best regards,
hanny
HD2 Hard Locked
Okay...so maybe Facebook is locking my HD2. It's LOCKED I'm recharging, I've attemted a soft restart, hard restart and every other restart out there...nothing is working. I even tried pushing the white button below the battery case and holding the volume up and down...I actually thought that it began to do a hard restart. It did begin but then it got stuck at the "swipe" demo. It is definitely stuck.
HELP!!!!

Fingerprint issues

How do you get the phone to recognize youe fingerprint? It is so annoying how it keep failing to recognize the fingerprint and asks to enter the code or pattern.

Go to Settings -> Security -> Nexus Imprint. Follow on screen instructions to register your fingerprints (up to 5).
I believe there is a setting to not have to input a code every time, check to see if that is your issue. I only have to enter a pin after a reboot, then just the fingerprint unlocks the phone.

I didn't explain myself well I guess. It happens to not recognize the fingerprint and then asks for pattern/code. It is annoying.
First I would say to clean it well. Second i would suggest you reset the print and add extra sets too. Also what ROM, firmware ect are you running? I have had flawless experiences with my sensor across various ROMs. I do a full set scan for 4 fingers. My 2 pointers and my 2 middles as well as another scan set for odd positions. This ensures no matter what I'm holding or position my phone's in it will be easily unlocked.

Running chroma 2/3 build with february firmware but I don't think that's the issue. I will try to register it again. Thanks.

I've had the same problem since the last week after updating a resurrection remix version. I think it's been doing something weird, but it'll unlock normal in the car and stuff so I don't know. Seems like when I put my finger on the sensor it will wake the device and want me to enter a PIN. If I put an unregistered finger on the sensor it won't wake it it'll stay black screen. It might be something to do with when you are at home with smart unlock. Hmmm....

I thought it could be the smart unlock and removed it but still same thing. Might have to go all stock and test it again. I had another nexus 6P before and that one you get unlocked really fast without any issues.
Edit: Found the issue. Double tap to lock ftom Nova was forcing the device to request pattern or pin.

How Do I Increase The Number Of Fingerprint Attempts

By default we have 5 attempts, how do I increase that? Because many times it does not recognise my fingerprint and I've come to the last attempt many times. Luckily it recognized my fingerprint on the last try. What would happen if all attempts were used? I don't want to try since I am travelling and don't want to lock myself out if that is what happens.
You can not lock the device on this way... Fingerprint works with PIN or password lock.
When you can not unlock with fingerprint, unlock it with PIN or password, delete that fingerprint ID and make new one (or two different of both hands) in optimal condition.
In my case fingerprint work fine, 99% at first attempt...

Bypassing Fingerprintsensor bug?

Hi everyone,
I notice that I can bypass my fingerprintsensor with tapping 3 times with the wrong finger on it and after the third time, the phone is unlocked.
I am on the last stock oxygenOS.
Does somebody else have this bug?
No.
No.
Yes I found that since the 1st day.
Now I tried twice with with a unregistered finger with the 3rd try another unregistered finger and it is unlocked!!!!
not all the time.

Doesn't happen to me. Have you got a pattern enabled?
After 3 failed finger print attempts the phone prompts for a pattern.
After testing, I was shocked to see that this worked on my phone...but after a little testing, it only unlocks on the third attempt when the phone has a smartlock device connected and doesn't require a PIN anyways.
If I turn Bluetooth off, the third wrong finger button press simply turns on the screen and asks for my PIN.

Smartlock was the key here!
I turned trusted places "home" off and on the 3rd try asked for the pin code.
So basically if I'm in trusted places or connected to a trusted device after 3 consecutive failed fingerprints it will open my phone without pin code

I think that's the point of smart Lock... ? So you don't have to unlock even with FP. Just swipe up and it should unlock...
That is interesting. Would only work around safety devices/places?

Lock screen bug

Just incase anyone else gets it, had a frustrating bug where after using the phone as normal throughout the day, I just went to unlock the phone using the to fingerprint unlock, which it said was unavailable and to use pin to unlock.
Upon inputting the pin it refused to accept the pin, was deffo correct used the same pin for years and years, no way I was getting it incorrect. No matter how many attempts it wouldn't work.
In the lock menu even holding down power I was unable to open the restart or turn off phone options aswell to compond the frustration.
After holding the power button for what felt like forever the phone performed a restart, the phone was able to be unlocked using the pin after the restart.
Had the phone for weeks and this is the 1 and only time it's occured. Just thought I would mention incase it happens to someone else
I can confirm that behavior and also the solution. Had that once as well.
Nearly the same issue here but in my case the power menu to restart the phone "normally" worked.....
