Question Circular hole on the inner screen - Xiaomi Mix Fold 2

Hey everybody,
Have you noticed that at a certain angle there is a clearly visible camera hole on the inner screen of the Fold 2?
Look at the upper right part of the screen where usually the signal bars are displayed.
Perfect camera sized opening under the pixels... I guess they initially designed the screen with an under-dsplay camera in mind, but for some reason decided not to do it at the end...

Ambient light sensor. Cover the hole with your finger and the screen will dim.

Poor Screen Uniformity

Anyone else have any issues in regards to the screen?
I can look past the horrible refresh rate/ghosting, but this is really bugging me, amongst other things.
It seems the bottom half, mainly in the left corner, is quite a bit brighter than the top, making it seem more yellow, and the top a darkish pink hue.
The bottom corners also have very noticeable light bleed strip down the sides, which is noticeable on any screen/colour. It's like a small bright 3mm or so wide strip each side.
Half way up theres also a mark that separates where the brighter part of the screen starts/ends, so I'm wondering if someone dented the back of the panel when assembling it in the factory?
Either way I've requested a replacement, I'm just more curious to see if it's a common problem or not. Ghosting aside, the screen itself is quite stunning to look at, especially with a bit of ambient light in the room.

i didn't get your question, but if it is that i have any issues in regards to the screen? then no, i think it's stunning...
I also have the light bleed in the corners but it's only really noticeable on the bottom of the right bezel (in portrait). The light bleed looks like a strip on bright white light running up the right hand bezel before stopping about a third of the way up.
This is my second z3 and I'm contemplating whether to bother with another replacement or just return it altogether. Can't say I've been won over by the phone so far...I may just go for the note 4 instead...

Built quality, glass si kinda moving

Does any one have problem with build quality?
When I push screen(glass) on left side near edges it's moving down and up, like it's not properly bonded. Also right bottom corner of screen is not in same level as edges, so it's kinda sharp when you go with finger over it.
I am not sure, should I go and change device or its like that on every device
Maybe you should get a replacement I haven't noticed that on mine.
I haven't noticed that but I did notice that when I was putting on a screen protector last night and looking under a light, you can see what looks like hairline scratches or marks on the glass. It's only when you hold the phone at certain angles that you can see them.
Mine has a tiny piece of trash or dirt under the screen, very small but annoying

Known Hardware Problems & Issues

Hey guys! what should I look out for after I finally get my S6 before the return window closes? Mainly on the hardware side as there is always the chance that the software gets fixed.
Alright guys! Lets start trouble shooting. i just got my S6 in topaz blue(MAYBE THIS IS IMPORTANT HERE as in: -> it's a lighter colour). and immediately i noticed a few bad bad things.
The softkeys do not light pure white but more of a beige hue(dirty white).Additionaly!! The silhouette of the lit light is shifted two times within the glass. What I mean is, that the conture of the lit softkey button can also be seen right above and below the normal place where the softkey lights up... so if it is lit I can see the symbol a total of three times. Depending on the angle of view on of the reflections(?) within the glass disappear. The notification LED has also the same kind of light shifting effect
The whole Metal-Bezel on the front feels quite sharp in comparision to the back side of it.
The Display has a slight green hue at the bottom of the display(almost the same color of the phone)
I am able to see iregularitys in the colour layer of the bezel beneath the glass on the top part of the phone. this can only be seen if a lightsource shines on it.
And lastly: OMG is the phone slippery! I think this comes from the fact the the only part which gives the phone hold on the side opposite the palm is the small edge side(opposed to the end of the bezel + a rounded back cover of some phones(Lg G2... so good to hold)).

Rear camera off-center

Probably a silly question. But I want to know whether the lens's position cause any effect on OIS when it's being completely off-centered as signified by the red circle in the image attached.
Thanks
I don't think it is a problem. If there is no black edges on screen when taking pictures, everything is fine.
And to see if OIS is turning on, just shake your phone (with camera off) and you can hear camera moving . Go to the camera app and shake again, you will not hear the camera moving. It means OIS is on.

I didn't mean whether the OIS will work or not, what I meant was whether the off-center will have any effect on OIS's working resulting in a bit more shaky video relatively?
Turn your phone around and it's centered.
Your welcome

I don't think so. I say this based upon my examination of the eight S7's I've possessed so far. Turning any one of them upside down appeared to merely cause an optical illusion. The illusion was that, if the back camera lens seemed off-center when right side up, flipping the device 180 degrees simply made it appear that the relative lens position had changed, often then seeming more centered.
If you look carefully at your S7's back lens (a magnifier helps), you can easily see that the lens itself is considerably recessed beneath the surface. That is, it is set back below the protective surface glass and the surrounding circular port opening. This means that when you look at the lens straight on, a crescent shadow is cast around a portion of the lens. And that makes it only appear to become more centered or more off-centered. The crescent shadow will change position depending upon the direction of your back lighting. You can hold your S7 facing its back panel, look at the lens, and pivot around in a circle to change the direction of the back lighting. You should notice the illusion of the lens moving from one side to the other as the back lighting becomes oblique from the opposite direction. A similar thing will occur when you turn the phone upside down.
Out of the eight S7's I've possessed, only one of them had a near perfectly centered back camera lens. As long as no portion of the lens is overlapped by the circular port opening, there should be no performance loss with the camera function. As stated, an off-centered back camera lens is actually only the position of the internally mounted camera module as relative to the external circular port opening. And the movement illusion is the shadow crescent moving around. The OIS movement should be so minimal that it will be undetectable in terms of how centered the lens appears to be.

Hi there.
I just got my S7 Edge today which seems to have the same misaligned camera and circular cover.
Did you notice any effect this has?

Small light bleed on midnight black s8

I never even noticed this before but I read a thread about it and than I looked at my phone and there is a barely visible light bleed above the light sensor like if it's just light barely peeking thru the glass it's not on the display. It's where the top bezel above the front camera meets the frame. Is this something I should b concerned about. It's only noticeable in the dark. Is it it defected or is it normal.

I have it too with my s8+, there is a little dot on the left side of the device where the plastic connects with the screen.
It's a production variance - you could argue it shouldn't be like that, but you'll never get a perfect phone due to variances in the tolerances during manufacturing... Mine has it too along the side (as did my silver S7 Edge before it).

But will this affect water resistance or is this jus light peeking thru glass

Depends on if its just light from mossing paint or an air gap.
The front glass is glass so its see through, and then there is a black flim/coating put on it. Then it is glue to the frame of the phone.
So if a piece of the black coating got messed up then your get light showing.
Now if its not glue down all the way and there is a gap then the water proof is gone.
There was a guy on xda that got his coarl blue s7e and one corner was missing some of the blue coating.
I have this light bleed over the iris scanner and the front camera. Then I searched where it comes from. I saw if I had a white screen (for example settings) and a high brightness a big light bleed in the front camera if you look from the top of the phone to the bottom of the camera. There I see light from the screen. It's not a problem for me, but have you guys this too? The question about water resistant is interesting in this case.
hope it's jus paint that is missing. That's fine with me. If it's not glued down right I'm gonna have to go exchange it. I'm gonna have to check it out more and see what it is.
I'm seeing something similar with my unit...but I think this is more of a light reflection off the interior of the case because of the space/void created by the two sensors in that area. I say that because the reflection occurs directly about the sensors and it moves around a bit as you change viewing angle. Am I crazy?
It is a reflection that gets passed on to the IR LED. Not a sensor.
Harmless, and seems to be on all units I looked at.

How bad is your bleed? I JUST noticed today that mine has bleeding on the right edge? But it seems to go all the way down the side? Mostly visible when there is something bright on the screen? There is also a little on the bottom left side of the screen..
So, can we say that the light bleed above the front camera is normal then? I have it too.
