My p20 pro doesn't unlock at night. It's not have any light to detect face. Is it issue on my phone? Or it's same?

Face unlock will need some light. Not much light but a little is still required. This is because, unlike Apple's implementation, Huawei doesn't use a laser to scan your face. Which obviously works in the dark and is invisible to the naked eye.
Now, I will say this... Face unlock works more often and much faster on Huawei than on Apple. The only weakness is that it needs some light. But my phone unlocks even in quite dark conditions and even when I'm in bed to sleep, but I'm not in pitch black. So although it may require SOME light, it doesn't need much at all.
So check your face scan data. Maybe rescan your face in medium lit settings like in indoor lighting or something.
In actual truth, although face unlock is more reliable and much faster on our P20 Pro than any other competitor, the more efficient way than even THAT is to unlock using the fingerprint scanner. It is faster and even more reliable. And likely more secure too.
No it's the phone it needs some light iPhone X is the same

This is what they claim. Not sure if it actually works in real life tests.
Although in general use, some reviewers have argued that in terms of success rate, the P20 Pro recognises your face more often than the iPhone X does.
For face unlock to work more consistently in darkness, you need a light coloured or white lock screen.

So I'm debating RMA's the N7 I have with Google Play. I have a slight screen raise (this doesn't bother me too much) as well as screen flicker that I notice in low lighting situations (mostly in chrome and maps).
Does anyone NOT have screen flicker? Or is this a software issue?

Hey, I believe the screen flicker is due to the auto brightness function of the device.
I personally don't like auto brightness at all, try turning it off in the brightness menu and see if you still get that.
I see the flicker quite often with devices having that function turned on.

Hmmmm well I guess the only thing I have to compare it to is my iPhone 4 which doesn't do this.
My eyes are usually sensitive enough to be annoyed by screen flicker in any respect. Certainly with overhead CFL lighting.
My 16GB Nexus 7 (2 days in my posession now) doe snot exhibit any sort of screen flicker whatsoever. This is in comparison side by side with my HTC Desire HD which also does not flicker.
The display actually has a very high quality feeling which I like.

Thanks for the feedback. So even in low lighting conditions, with auto brightness set to on, and scrolling around in chrome / maps, you screen never flickers or sort of rapidly dims?
I've noticed it. Only on white web pages or books. Very slight. I had two HTC One Xs that both had it. Its a Tegra issue and doubt we will see a fix. Gutted.
Its not the whole screen. Noticeable around text especially. Some weird refresh prob. Left side of my screen is also slightly raised. Not happy.

I definitely get it on the whole screen, maybe for a second or 2. Might do it 2-3 times per day at most.
double post - deleted
Happened to me, I just turned the auto brightness off and t was fine. Try it, it works.
I keep auto brightness disabled and I haven't noticed the flicker that I can remember but tonight I'll try to reproduce and check it both ways.
I disable auto brightness and use this app which is actually a widget. It allows you to UAW any edge on the screen as an invisible or barely visible slider for brightness. It allows for incremental 1% changes on a slider instead of the typical button/toggle widget and its always enabled if you set it that way which allows on the go ease of use no matter what app or screen is open.
Its helped me attain amazing battery life and always have quick access for setting it just right.

I understand that - I'm trying to gauge whether or not it affects ALL N7's, or is a defect.
Google Play is shipping me a replacement N7 to address the screen raise on my current one, and I want to make sure the replacement is 100% A-OK.

Make a poll if you're trying to do that.... But yes, I see flicker too, but only at very low backlight levels and seems to be when wifi is active. I haven't tested to see if it's just wifi, or wifi causing other things (disk activity, etc), but this is the general consensus so far in the other thread.
As the subject. Is that my impression or something well known? Is there an app/setting to make it more natural?
Thanks!!!

Looks fine if you ask me.
I'd rather have it more saturated than have it looked washed out.
Its different compared to GS4 or iPhone but not bad. Considering I regularly get 3± hours screen time on a 24+ hour cycle I have no complaints.

Compared to my S2, the screen colours and black are amazing. Hard to even look at my s2 now.
But.... Some can find fault in anything somehow. Lol
Sent from my Moto X cell phone telephone.....
The screens and saturation levels do vary a little phone to phone. I have played with 3 Moto X's quite a bit now and each have been different. My first one isn't over saturated at all, the screen on it has a little more yellow to it. The other two have more of a blue tint and show more saturation. The whites do look better on the second two but the first is easier to look at in the dark.
I don't think there is any way to adjust it or even change the DNIe mode like Samsung allows. People wrote custom kernels for the Nexus 4 to allow color adjustment but there aren't nearly as many devs working on the Moto X, so you're probably stuck with what you get. I don't imagine that they do any factory calibration to speak of, so of course it will vary greatly between panels.
Unfortunately, oversaturated is the new properly calibrated. The problem is that it has a better off-the-shelf look when people who are clueless are comparing models in the store--hold a Moto X or GS4 up next to an iPhone or Nexus 5 and the colors "pop" more, which seems to be more appealing to the average consumer than the more muted appearance of a display with proper sRGB calibration.
Cool. Thanks guys. In on a xperia z1 and the display is amazing. So using the motox is very different. But yep I should be used to. Another thing I noticed is that is way less bright under the sun. Again I think is just a calibration thing since we if you switch to manual you can increase it much more than the way our light sensor detect it.

You can try the app Lux to control auto brightness and Screen Adjuster to try to correct the colors.
Hey guys,
I started noticing bit of red tint on lower half of the screen.
I am aware viewing angle make difference, but no matter which orientation/angle I look from it is still there.
Anyone else having similar issue?
Also, if this is a defect, is this the kind that retailer usually replace for consumer?
It is giving me headache looking at the screen for a prolonged period even though the tint is not severe.
Sent from my SM-N910U using XDA Premium 4 mobile app
Its very, very slight on mine. Nothing that would make me consider returning it though.
Also, screen tint shift based on angle is a lot more frequent than my s3 (i9300). I tilt note4 by even 5deg and I see colour shift already, but nothing like that on s3.
Can someone confirm this please.
Thank you.

Yes, my phone does this. However I've checked a lot of shop display units and have noticed many are better and some are worse than mine. The sad fact is that there seems to be a bit of a screen lottery going on and it's luck whether you get a good screen or a bad one.

You can try it. If they have a display unit that is obviously better than your current one and they can see that. Problem is you might end up with a replacement that is just as bad or worse!

Thats been the case since the Galaxy Note 2, even my note 3 has a slight reddish tint on the top part of the screen.. most if not all the units ive seen either has a red tint or a more warmer color tone at a certain part of the screen. People have accepted this as a norm.

Agree. My old s5 was much better with colour shift and tinting. As are the new tab s tablets. I'm disappointed with the note 4 screen.
Have you tried setting the display to photo mode?
I am still wondering if we talk about the same phone, my Note 4 has no red tint and no color shift at all, no matter how much I turn the phone.
Also looking at a totally white/red/yellow picture, I can't find any part of the screen that is warmer. Some people also reported that greys look terrible, I can't comfirm that for my display.
Coming from the Nexus 5, this display looks so much better in all aspects, I am still stunned after using the phone for 3 days now.
There seems to be quite a disparity between phones. Some are good, some are bad. That tends to be why people are having different experiences.

It was the norm for the S series up until the S4 came out. The S4 was the first Samsung screen since the Note 2 that had a very nice and even screen.
S1, S2, S3, Note 1, Note 3 all suffer from poor screen uniformity. Guess you can add the Note 4 to that too.
This worries me as I'm planning on skipping the Note 4 for the Nexus 6. Samsung will already be giving Motorola last years Amoled tech, and stretched across the bigger screen the unevenness will be even more obvious.
Especially now that Android Lollipop will be mostly light grey everywhere! Amoled's worst nightmare.
red tint?
What red tint, is this when the screen is on? off? I haven't noticed any red tint but now I'm worried...

Wow, if you do not notice it - do not find a reason to notice it. Be happy with your device.
My display is a very slightly more blueish/pinkish towards the top half, specifically the top right. It's only noticeable on white content. It's subtle enough that I won't go through the hassle of getting a replacement especially since the replacement could be even worse... At least my display has been brightness and no banding or anything. Overall though, this display is simply phenomenal. Hopefully these slight display issues will improve as time goes on, although the screen on my S4 was very uniform, doesn't even come close to the performance of the Note 4 screen though.
Seems like the problems are much less pronounced that the typical uneven backlight of LCD?

I'm on day 2 with this phone, I've just moved over from a Note 8 and so far loving it!
It's still early days and not sure if over time I'll regret my decision coming away from Samsung, after being with them for a last 3/4 years, but I fancied a change and got really annoyed with the battery life on the Note 8!
Anyway my post is about the Face Unlock on the Mate 10 Pro, which came via the OTA update, well its soo much better and quicker than my Note 8 that it's maybe a little too good! For instance I like that it detects me even when wearing sunglasses, the Note 8 didn't, but when I'm at work I put my phone on my Wireless Charger (I know this doesn't have wireless charging before anyone says anything, I'm just using it as a stand atm) and when I get a notification come through my phone unlocks ha!
I have the setting on so my phone screen lights up when a notification comes through, similar to iOS, along with face Unlock which is rapid, it just unlocks my phone!!
I'm not complain just surprised at the difference between the Note 8 and Mate 10 Pro!

Mate 10 C636 on april update (.134) and I just tried face unlocking after having this phone for months, its super, super, incredibly fast. Works in dark areas but not super dark areas. I tried it on a dimly lit room and it worked, on a room with no lights it doesn't work because it doesn't use infrared.
I'm blown away by how fast it is.. I wanna bet $100 that this is so incredibly fast because the face detection is done by the NPU which is purpose built for stuff like this..

You can change that it goes to homescreen automaticallybut you stay on lock screen. There is a setting that disables going to homescreen but still unlocks the phone. Then you only need to swipe to go to homescreen or double tap the notification.
I have that turned on because I like to check my Lockscreen before deciding whether I want to use the phone (see who texted before deciding whether I text back or ignore).
Additionally you can enable that the contents of your notifications are hidden unless your face is detected. This way you nosey GF won't be able to see your side chick texting you. Lol
edit: i never managed to fool it with a photo. tried many times.
Fast but not accurate
As a camera with nothing else its so quick but I've got problems because it detects my twin brother as mine "some times" but its good enough

It doesn't, you need a well lit environment for it to work properly. Basically it stores photos of your face during the setup and compares them with the current captured photo when you are trying to login.
I mean with the light from my laptop it does work. Decent enough. But it's nothing fancy or 1+ status. I do have it on because it's convenient enough though.

Yeah I use face unlock too which is faster than using fingerprint, to be honest I am really disappointed with. So far face unlock works 95% of the time compared to 70% of the fingerprint.
