Strange issue with face unlock - Huawei Mate 20 Questions & Answers

I've got Nova Launcher installed and when I lock the screen using a nova lock screen widget, after two seconds it automatically unlocks the screen again and goes back to home screen.
It's clearly related to face unlock because when I cover the camera with a finger, the phone stays locked and doesn't unlock itself again.
When I change nova's unlock method to "admin" everything works fine but this method requires a Pin to unlock so I don't want to use it. The "accessibility" method is much preferred.

Anyone experiencing this??

[Q] Pattern Unlock Only

How do I change the lock screen so that's it pattern only. Like the idea of dragging icons into the circle but am currently unlocking the phone and then having to enter my pattern. What have others done about this?
Never had this issue. Are you using a different ROM? If so ask the author. But every time I use an alternative lock method I never go through two lock screens.

[Q] Widget Locker Help

I have been trying to get Widget Locker working on my One but have hit an issue. I am thinking I may not be able to fix this without Root but I wanted to run it by the community to verify.
I have my phone linked to an Exchange server that forces a 4 digit pass-code onto the device. So from the default lock screen I swipe up and then get the keypad to unlock the device.
Widget Locker replaces the main screen and 60% of the time when I unlock the device it takes me to the keypad directly.
The other 40% of the time is the issue. When I unlock from Widget Locker it takes me to the default screen where I would swipe up. From this point I can ether swipe up and unlock or shut off the screen. When I try again it usually works perfectly.
Is there any way to get consistent behavior from Widget Locker without root? What I would expect would be to unlock and be taken to the keypad 100% of the time.
I would love to use widget locker, but I always get a 3-7 second delay with turning on my phone. Sorry I can't help you.

Go into Settings and set the HTC lockscreen to none. It forces the phone to only use WL, and you never see the stock lockscreen. Works for me,

That kills the security on the phone. We need to have ether a pin or password unlock to secure the device. Even without it I would want a pattern unlock at the least to keep it somewhat safe.
I expanded my search a bit and this seems to be a common problem on phones that have any sort of lockscreen security. What I cant understand is why it does work some times, but not others. It does not appear to be a timing issue but I cannot narrow down what else would randomly (apparently random) trigger the stock lock screen yet work other times.

No, it doesn't. The HTC lockscreen and the Security lockscreen are two different things. You can have the HTC lockscreen set to none, and still have the option to unlock with any of the various lock methods(i.e. PIN, Pattern, Face Unlock, etc...) I know this is true because I use it everyday. I use WL, have my HTC lockscreen set to none, and still have to enter a PIN to unlock my phone. And have no delay when using WL once the phone is booted.

And I am an idiot. You are completely correct. I am trying it now, thank you.
Edit: Working like a charm. If anybody else is having this issue the setting is under Personalize, lock screen style.
Thanks again!

Fingerprint senor only wakes, doesn't unlock

This is what is happeing to me. If my phone is locked for more than 20 minutes or so, when I use my fingerprint to unlock the phone, it only wakes th phone, I.e.turns the backlight on, but doesn't unlock it.
The fingrprint registers correctly, as the screen wouldn't wake otherwise. I'm struggling to understand what the problem could be.. maybe its Go Launcher? Maybe its lightflow? Or someway around notifications?
do u have a pin set up or pattern
Yes I do. When I use my fingerprint, it takes me to the screen to input my PIN

I had the same issue when I turned on douple tap to sleep in novalauncher. Once I disabled it, the fingerprint reader unlocked my phone, not taking me to the pattern screen. Its certainly a software problem, I guess it's your launcher.
I'm using a older version of Go Launcher EX (5.09). Its very old, but does the job for me.. unfortunatly it doesn't have the double tap option.
I'll try disabling it and see if th problem persists
Edit:
With the Google Now launcher, when I use this app to lock, the same problem occurs. I lock by clicking the app, but then when I try to unlock using fingerprint, it takes me to the PIN screen

If you want to use fingerprint unlock function, you need to install FingerprintEnabler xposed module. Else the fingerprint to screen on and ask for pin or pattern is the default behavior..!

Cannot unlock screen with fingerprint, after locking it with a shortcut

Hi,
Iv'e owned many phones with many different android versions from Kitkat to Nougat, and while i was changing UI's and launchers every now and then, i always kept 1 thing permanent: I had a shortcut (whether 3rd party or from the launcher) that locked the screen when clicked.
There was never an issue to use this shortcut to lock the screen, and then unlock the screen with the fingerprint reader, there was no waiting time between locking and unlocking and this feature always worked flawlessly.
In my Zenfone 5/Oreo/Zen UI it doesn't work anymore: You can now use one of 2 options, either to lock screen immediately but cannot use fingerprint to unlock afterwards, or to dim the screen which will lock regularly after 5-10 seconds.
Both are the options are annoying, what happened to the way it used to work before?

lag after face unlock?

I have had the phone for about a week, and it is very fast, but I set up face unlock yesterday and it freezes up when it gets unlocked that way. If I unlock it quickly after screen off it seems fine, but if it has been resting for more than a few minutes, I get a black screen (with the software buttons back menu home but they are unresponsive) for 5-10 seconds. Anyone else getting this or know of a fix?
I have not had this issue. Face unlock is quick whenever I use it. I do have raise to wake on and stay on lock screen after unlocking set to off.
I also use nova launcher.
Happy to test mine with different settings if you let me know how yours is set up.
Ian
same settings and nova launcher, except not stay on lock screen after unlock
Have changed that setting to match yours and still fine. Might be worth giving it a try with default launcher just to see if it has anything to do with nova launcher.
Otherwise I am not sure what else to suggest.
