P20 Pro intermittently launches camera when fingerprint unlock used - Huawei P20 Pro Questions & Answers

Hello,
Has anyone else come across the following with the P20 Pro (mine is a CLT-L09 on firmware 8.1.0.131(C782) - but the issue has occurred on all firmware versions I've had to date).
Occasionally when I unlock the handset via the fingerprint sensor, the camera launches rather than the handset just going to the home screen.
Currently I have the face unlock, lift to wake and the fingerprint unlock turned on. However, I have tried turning off the face unlock and the lift to wake - but the same thing still happens.
I'd say it probably happens about once in every ten unlocks.
I don't know whether I'm accidentally pressing something which is causing it - the camera icon is in the bottom right corner, so I'm not catching that as I unlock with the fingerprint sensor.
Any ideas please?
(I moved from a P10 Plus and never had this issue with that handset).
Thanks in advance.

why do I have to scan my finger twice to unlock?

Hello,
I bought the Moto X4 through Amazon with the Ads and latter hated seeing them so I paid for the difference to get them off. I issue is that Everytime I unlock the using the fingerprint sensor I it just takes me to my lock screen and then I have to swipe up or I have to use my fingerprint again to take to my home screen. It did the same thing while I had the Amazon Ads i always had to do it twice to unlock my device completely.
Does any body else have that issue or is there a way for it to be just on scan and take me directly to my home screen?
I'm on the Android One version on Project Fi, and that is not how mine works. While the screen is off, I press my finger on the sensor, and it bypasses the lock screen to open my phone immediately. Works the same with both fingers I have added.
The G5 Plus had a faster fingerprint sensor.
Is there any way to use my fingerprint scanner only once and directly take me to the home screen instead of the lock screen?
Mine works like that. Just touch it and unlock directly to the home screen. Idk why your didn't. Try to remove fingerprint unlock and set it again. Must work like it should.
My guess is that this is a behavior of the Amazon version that shows ads on the lock-screen, so they have to force you to take an extra step so you actually see the ads.

Screen wake up time has increased significantly

After the latest update (.140) I have noticed that the fingerprint sensor has slowed down awfully. It takes like 2 seconds to unlock. But it seems to be snappy if you manually turn on the screen and then unlock.
Meaning the screen wake up time is the issue here. It won't just wake up as soon as I press the fingerprint sensor. And it's getting super annoying.
Has anyone else noticed this issue?
Model : COR - AL00
--------------------------------------
Update : As I suspected it's not the fingerprint sensor after all, it's the screen itself. The screen is taking much longer to wake up, even when I try by pressing the lock button it takes a significant amount of time to wake the device up and turn on the screen, is anyone experiencing this issue?

It is the face unlock. The phone processes the face first before waking screen in order to skip the lockscreen after unlock. Disable it if it bothers u too much and it will be normal again

Fingerprint problem after changing screen

Hey everyone,
I just changed the screen (with the full assembly) on my P10 and I have a weird problem with the fingerprint sensor.
I can add new fingerprints just fine, and if I try to set the same finger 2 times I get a message saying I've already saved this fingerprint. But, I can't seem to unlock my screen with the scanner. The screen wakes up when I scan my finger but the phone doesn't unlock even if the option is activated in the options.
I really don't know what to do.
Same problem here, is software related problem. Try to do a factory RESET. In my p10 was solved on the pie update.

Question Fingerprint sensor unresponsive after update

I'm running MIUI 12.5.6, and since the last update the fingerprint sensor has become temperamental.
Previously, just touching my thumb to the power button would unlock the screen.
Now it will sometimes unlock, but other times I actually have to click the button.
Anyone else experiencing this?
Thanks
Try unregistering and registering from scratch.

Question Critical security issue?

Recently, I have begun to notice that when i double tap on a locked screen to watch the time, smartphone sometimes unlocks itself. It's worth noting that I didn't set up face unlock and I didn't touch fingerprint scanner. Does anyone else have such issue? What could be the reason?
Unlocking with a trusted Bluetooth device is also disabled
