My iPhone 14 Pro Max looks the outer area of the screen.
The "blob" looks almost like something is under the screen.
Viewed normally, the screen looks perfectly fine.
If anyone has one of these lights, can you check your phone to see if it looks like this?

Other phones have this too. Did a cursory google search. First page threw up results like these:

This was seen on the Note 9 and Note20 Ultra. It likely has to do with the adhesive to the frame but it doesn't effect the screen in normal lighting. Given the prevalence, it's probably not a defect.

First time I noticed this. I will check my Pixel 6 Pro next.
Interestingly enough none of the iphones show this.

I gonna guess that it's the OCA/LOCA (Liquid - Optical Clear Adhesive)
All modern phone screen use either one of those two to glued the glass to the image display panel.

on the screen over the menu button you can see button light that brightens up the right side of the screen which is quite visible in dark enviroment.
did any1 else noticed same thing on their gear or should i expect the screen was replaced with non genuine one?

Does everyone have the "rainbow effect"? It's deal breaker?

Just brought it, i really like it in all aspects except the annoying rainbow effect, i can even see it without tilt the tablet, especially in landscape, just wondering EVERYONE have this problem? after some time of use you get used to? any way of fix it?
I was thinking of change it but it doesn't make sense if all units are faulty
Rainbow effect:

I am unable to access your screen picture but my tablet is perfectly normal and has none of the aberrations you describe. I was in a shop yesterday and handled the two display models and they were fine too. So I would suspect a fault with yours.
Here are the pics http://imgur.com/a/mpuTI#0
So your tablet doesn't have any of this when you tilt it?
I noticed a rainbow effect when I first got mine, but now I don't see it at all unless I really look for it.

No, none of that. Using the same Google page,I have tilted it in every direction and it is a clean high quality IPS screen with no artifacts.

OPX AMOLED Screen Uniformity?

Does anyone else notice any uniformity issues on their OPX from top to bottom of the screen? By this I mean does the bottom of the phone seem slightly darker then the top when displaying colors?, most noticeable when displaying solid grey, and slightly more noticeable at lower brightness levels. I have read many other forums regarding Amoled on Samsung devices and a lot have had this same issue which is described to be normal for these displays. I even had an extreme case when I bought a Samsung Galaxy Tab S, however the second unit I got was much better. Here is one of the forums below, I will also post some of the images on my screen. See the color of the green on the Google play store from left to right, as well as the grey's left to right in spotify app. From my observation the screen looks darker on the left then the right. Please let me know if anyone else notices this and if it is normal, I really do not want to go through the hassle of a return if unnecessary.

Any comments here? I would really appreciate knowing if this is normal. I am trying to deal with Oneplus support and not having a good time, I would rather not have to send this back if I would most likely get one with the same effect on the screen.
Weird, never noticed anything like that

Is the aperture broken? Picture.

The apperture look like the blades arnt fully retracted for f1.5, it has a star like shape instead of normal big wide opening like in the telephoto camera.
This happened while doing some long exposures.
It fully opens in live focus mode only, in auto it stays like this until you expose to high light then it closes but mostly will stay like this.
This exynos version is really bad, I managed to barely squeeze 7 hrs of SOT (instead of 4:30 5) but....the constant 40 'C burning in my pocket is unacceptable.
I'll be sending this back since I can return it in 30 days.
I hope the note 9 wont have the same issues.
Also that iris scanner is much slower than the note 8s one:crying:
The picture doesn't work, but from your description it does indeed sound like an issue.
Things should look like the picture from this article (right under the photo of the blue & purple phone).

Transparent Galaxy Note 3 (Skin Template)

Well, as you all know, Galaxy Note 3 is quite old, and barely gets supported by most accessory manufacturers nowadays, so I decided to take some pictures, and scan the internals of my Galaxy Note 3, and stitch it all up, so I can use it like a transparent skin mod on my clear case, and I wanted to share it to you guys, so enjoy printing lol.
(You might be wondering, "take some pictures"? Yeah I did, I used multiple images and stitch them all up. Normal methods doesn't produce the desired clarity: Scanning the whole phone opened, produced blurred components, and are out of focus, and only those that are touching the glass surface of the scanner are that on focus, such as the battery, pen and the camera; Taking a normal whole picture of the phone, on the other hand, didn't have the blurring issue found on scanning, although the resolution of the picture is affected by my other phone's Camera resolution (which is 12MP). And so, to workaround this, I instead took multiple pictures of the parts of the phone. That's why you can see some unbalanaced lighting here and there throughout the image.)
