So, I had one Galaxy S4 and with my polarized sunglasses I had no issue seeing the screen. The home button broke and I got the entire unit replaced, now whenever I look at the screen with my polarized sunglasses it is dimmed significantly.
What is your experience with polarized sunglasses and your S4? I'm wondering if it's more common or not to have issues with them on the S4. I know *very* common with screens to have an issue with polarized lenses
Mine is really clear. No problems at all

Can see mines fine. However it might be different from screen to screen. For example my Pebble watch... I cannot see at all with my polarized glasses on. And my iPhone 4S was hard to read as well.

LCD screens use polarization to create the image, you can see the details here in the LCD wiki. Because of this, using polarized sunglasses will make the screen appear dark in certain orientations. AMOLED on the other hand has sub pixels for each color, negating the need for polarization. If any polarization patterns are seen, it would be caused by the tempering process of the gorilla glass (and i'm not sure if this would even be seen in polarized light)

Apparently the Galaxy S4 active is shipping with a TFT display and not the AMOLED. I wonder if pressed for production, Samsung is starting to put the TFT display in the regular S4 also now? I'm going to put my screen under a microscope to check if it's AMOLED with subpixels and all.

Never thought of the active. I would suspect differently though. LCD's are known to be better in direct sunlight, AMOLED is catching up, but for a phone designed for the outdoors person, Samsung may be taking no chances. I also don't see the active being advertised as an AMOLED like the s4 is.

I checked under a microscope, comparing an iPhone 4 and a Galaxy S3. The pixel layout I saw on my Galaxy S4 and Galaxy S3 matched this image and other "microscope" images of the Galaxy S4 AMOLED.
http://i-cdn.phonearena.com/images/...Galaxy-S-4-on-the-right-screen-comparison.jpg
So, after seeing the pixel layout I'm absolutely confident it is an AMOLED. When I displayed a completely black image, there was absolutely no light coming through the display either and all pixels were turned completely off.

I have to tilt my S4 45 degree to the left to be able to view it clearly with polarized sunglasses. If I hold it straight, it is pretty dark, and if I tilt it 45 degrees to the right, it is nearly black.
Just wanted to mention with either of my polarized glasses my S4 is totally unaffected.
Interesting that there are differences in the manufacturing/tempering process.
Mine is also unaffected. I have tried with multiple sunglasses aswell

What you are saying is pretty much impossible with AMOLED displays. It may not be the normal orientation, but there has to be some orientation at which the screen is darkened. The only other explanation is that the sunglasses you tried were not actually polarized. You're absolutely sure?

Interesting, will perform some tests tonight.
I know both glasses are for sure polarized as they block out my cars display at certain angles.
I'm 99% sure of my statement, wonder if I can record the effect somehow with another camera.
Will let ya know.
It's likely just a matter of the build process - the polarization of the screen could be different in newer [sub]models. From one AMOLED screen to another, I've noticed the same problems, but it depends on what polarization the glasses have, what ANGLE the polarization is at, and what angle the polarization is on the device screen. I also have to tilt my head at least 45deg to get it 100% bright, and holding the device sideways works fine.

This happened to me on my galaxy skyrocket, but only because the screen protector I had was polarized and "anti-glare". I do not have a screen protector on my S4 and it doesn't happen there. It's interesting if it is a difference in production, because polarization does cut down light output a little.

It is quite interesting indeed. I haven't done much research on it, but I think it's something to do with keeping the light from bleeding into nearby pixels - keeping the image sharp and clear when looking at it head-on.

I've noticed this on my S3 and my new/used S4.....
I also have an "off colored" strip about 1in long you can ONLY see with polarized sunglasses. Not sure if it's the Zagg screen protector that's wrinkled slightly in that spot, or if there is a scratch on the screen on that spot under the Zagg? My S3 did that wherever it had a scratch... The Zagg covered the scratches, but couldn't hide it from my sunglasses. I don't want to take off the Zagg on the S4 to see if it's actually scratched or not, maybe someday when I get a spare $30 for another one I'll check it out.

Just wondering. When the screen is off, why is it as black as the bezel around it, same on my One S, but on my Galaxy tablet and some other phones, it's grey and you can clearly see where the screen is?
I thought maybe the glass is darker, but wouldn't this screw up the contrast/colours of the screen? Or maybe the material doesn't reflect light as much, but what material is this?
It's the screen. Amoled's backlight is from the pixel itself and doesn't need any source for backlight. It's those backlights on non Amoled screens that make black look grey.
Edit...
Misread what you asked. Thought you meant when the screen is on displaying black.

You're pretty much right. Its the sheet of plastic that they use in the screen. It all depends on what type they use. It varies from screen to screen. Samsung uses AMOLED screens so they use a different type of backlight. Samsung tablets use PLS though, which is like their version of IPS. They use a lighter backlight so it looks different. I personally don't like PLS screens or bad IPS screens (like this phone). The off viewing angles are pathetic. Good IPS screens like on the Lenovo Yoga or the HTC One are great, but otherwise I prefer normal LCD. Just my opinion

Yeah but the viewing angles (in my experience) are bad if its not a high quality panel. I find the veiwing angles of this phone terrible and there's no denying it. Compared to the htc one, its horrible. I'm not trying to start a fight here, i know this phone is $300 cheaper than the htc one, but still, I prefer wide veiwng angles.
Actually my only gripe about the Nexus 4 aesthetically is that it's NOT as black as the bezel when it's off.. Sometimes it's grayish, sometimes it's actually darker (depends on the lighting). the Gnex was uniformly black when it was off (which is the one thing I loved about the design), while outdoors I can easily see the "gray" of the N4's bezel (screen if you're indoors) when the screen is off. Wish it was all black, looks much better that way.
The LCD itself is an important part of why it looks like it does, but the more important factor is that the LCD is optically bonded to the touch surface, leaving no space for light reflections, air, etc. between the touch surface and the LCD itself. In LCDs that are not so bonded you see light reflecting off the touch surface, but also light that passes through the touch surface and reflects back off the LCD surface. In an optically bonded display assembly much less light reflects off the LCD surface because they put glue or a similar substance between the touch surface and LCD so there's no air between them.
From memory it is the polarizing filter/layer(s) that dictate how dark the panel is when it is off.

AMOLED doesn't use any backlight. IPS/PLS/TN/PVA/etc. all use either CCFL or LED for backlighting, the brightness/dimness of the light source effect brightness when the display is on but not when it is off.

This is really just a problem with how LCD's in general are made. Can't really do much about it other than different sunglasses as you mentioned.
I wonder if that was my question. I remember posting about it in the old N7 forum. At any rate, thanks for posting this! I'm still holding out for the LTE version.
Things can be done with the design to make lcds useable with polarized sunglasses. My xoom only blacks out on 2 of the 45deg angles. Works fine landscape and portrait. My s4 is fine during 360deg just slight color shifting mainly just at the 45deg angles.

So after some very confusing moments I just figured out that the Z2 screen is polarized so when holding the phone in landscape for example while taking a picture, you can't see the screen if you are wearing polarized sunglasses.
Here you can see it in a video I made:

This is the first time I see this in a smartphone, it's a little bit annoying, anyone knows the reason?, maybe the polarizing filter in the screen of the Z2 is what makes it a little bit dimmer than the competition?

pretty sure its to make the screen more visible under water... maybe.
edit: just googled, most phones have it now to stop glare from sun. thats it.
I know polarizing glasses stops water glare.. not sure how itd work under water though.
After seeing this first hand today it's a definite deal-breaker for me, as every pair of sunglasses I own are polarized, and I have no intention of changing that. I never had an issue before seeing the screen of my HTC One X & One M7 outside wearing sunglasses & taking photos in any orientation. Since the Z2 I received this week has a gap the size a credit card will fit into on the bottom left & both cameras are very off center I was going the exchange route but after noticing this today, no thanks. It's really a shame, maybe a future Xperia will be better though.
I found a review that mentions this issue on Pocket Lint: http://www.pocket-lint.com/review/128493-sony-xperia-z2-review
FWIW I have read elsewhere that the HTC One M8 shares this same issue too.
It is pretty daft considering most holiday snaps will be taken in landscape with the sunglasses on.

I guess Sony missed this one. Almost all LCD displays have a polarizing filter, but they are usually set to polarize at 45 degrees compared to sunglasses (or vice versa). You can try this by looking at an LCD display (not the Z2, obviously) or your digital watch through your sunglasses and then turning the glasses slowly.
BTW, my Google Nexus 7 tablet is also polarized at 90 degrees. I can see nothing in landscape view.
But my computer display and even the LCD in my car dash can be seen clearly. Unless I tilt my head 45 degrees.

Then your sunglasses aren't polarized, because the screen definitely is.
If you research LCD technology you will see a polarizing filter is required to make the screen work. If you then have polarizing glasses then you will have this issue. AMOLED technology is superior in this respect because it does not involve the use of polarized light.

The flaws you mentioned are present on almost all Z2's, so you aren't going to find one without flaws. Also if you are going to avoid a purchase of a phone strictly because you can't lift your glasses up for 3 seconds to snap a picture once or twice a month, then I wish you luck with your other life endevours lol From what I understand most phones with LCD's have polarized screens, so you may not be able to find one that doesn't have it. The Z2 is a great phone I wouldn't consider anything else.
Z2 is probably polarised for sunlight legibility. My tablet Z is also polarised in the opposite plane.

Yep I also had problems with polarised sunglasses looking at my Z3-C.
Pain in the arse really because I wear them while driving (prescription lenses otherwise I use regular glasses) and it makes it impossible.
That being said, it saves me from getting fines
It's better than my old M8, which was completely black in portrait mode while looking through polarized lenses.

Funny, I see rainbows and weird colors when looking at my wife's iPhone 6 through my Maui Jims. It depends on what glasses you have as well as what type of polarizer is used for the screen. AMOLED or IPS LCD doesn't matter as they both can have these issues depending on the glasses.
I have a pair of $200 Raybans that don't rainbow on anything really other than the displays on gas pumps
I received my Axon 7 on Wednesday this week. The AMOLED screen does have very good blacks and looks vibrant, but there is an issue I haven't seen discussed - I'm trying to determine if its just my phone, an issue with AMOLED in general, or perhaps a coating specific to the Axon 7:
When I view the phone directly, whites look correct (warm, natural or cool depending on the Display setting). However, turning the phone even a little off-axis, 10-20° either vertically or horizontally, introduces a very small blue shift - whites especially take on a bluish, sort of washed-out cast. It makes the colors seem much more shallow and unreliable. Can those of you who received your phones go to a WHITE or light-color screen and report if this happens for you too?
This is actually hard to identify, most people will just see something is a little "off" - to my eye, it looked like a very subtle version of a TN-panel color shift. I never have seen this on an IPS panel, though off-angles may get washed out (see Nexus 5/5X) quickly at 50-60°, they always retain their color, even if it lightens. Or, e.g., the Moto X Pure 2K IPS panel that I'm coming from has zero off-angle color shift, no wash-out, and just darkens a little even at 180°. This is my first AMOLED panel, so I'm not sure if it happens often.
If anyone can help me determine whether this is a defect or an expected limitation, that would be great.
I've noticed it on my A7 too. This is my first AMOLED phone, so I too am not sure if this is normal.
I see it also. Thanks a lot now I won't be able to insert it.
For now I will blame the screen protector that came in the screen.
Welcome to Amoled.
The cheap screen protector contributes too,
Thanks, all - I guess it's just the phone then. I actually don't have the screen protector insert applied, so I assume the "screen protector" refers to the factory glass overlay.
Does anyone know if even the new Samsung AMOLEDs exhibit this shift? I think the Axon 7 is technically a Samsung panel, but I wouldn't be surprised if Samsung kept the best AMOLED technology for themselves.
Not sure this is a dealbreaker, but it's definitely a step down from the great color-true viewing angles on the Moto X Pure. (Too bad Moto abandoned the good design the Moto X Pure had for gimmicky snap-on modules this year rather than iterating - it seems like the Axon 7 is otherwise the spiritual successor to the MXP.)

Does anyone know if even the new Samsung AMOLEDs exhibit this shift? I think the Axon 7 is technically a Samsung panel, but I wouldn't be surprised if Samsung kept the best AMOLED technology for themselves.
Not sure this is a dealbreaker, but it's definitely a step down from the great color-true viewing angles on the Moto X Pure. (Too bad Moto abandoned the good design the Moto X Pure had for gimmicky snap-on modules this year rather than iterating - it seems like the Axon 7 is otherwise the spiritual successor to the MXP.)

Of course Samsung keeps the top production panel for themselves... However, it's still a great panel according to colorimetry tests.
Don't notice it on my unit. Jumped from a galaxy S7 edge to the Axon 7 and the display looks exactly the same to me.
This is an area that has driven me a little crazy. I'm used to my Samsung AMOLEDs (Note 4, Note 3, S3, etc.), and they don't have any noticeable "shift", This screen is gorgeous, but it's not a top-tier Samsung panel (obviously). Still, small price to pay for a 400 dollar savings over a Note 7. I am also positive the matte screen protector isn't helping. Once my tempered glass one gets here, I will switch it out and see if it makes a difference.
Which tempered glass screen protector are you getting? I have not read one good review for any of them...yet.
As an update, I went and tried some floor model Galaxy phones at the mall, and they actually had worse off-axis blue shift. Not sure if that's because of the initial screen quality, or that it got worse over time.
Does anyone know of any AMOLED phone (specific model) that does not have any perceptible shift? Does anyone know if the shift gets worse over time?

I received my Axon 7 on Wednesday this week. The AMOLED screen does have very good blacks and looks vibrant, but there is an issue I haven't seen discussed - I'm trying to determine if its just my phone, an issue with AMOLED in general, or perhaps a coating specific to the Axon 7:
When I view the phone directly, whites look correct (warm, natural or cool depending on the Display setting). However, turning the phone even a little off-axis, 10-20° either vertically or horizontally, introduces a very small blue shift - whites especially take on a bluish, sort of washed-out cast. It makes the colors seem much more shallow and unreliable. Can those of you who received your phones go to a WHITE or light-color screen and report if this happens for you too?
This is actually hard to identify, most people will just see something is a little "off" - to my eye, it looked like a very subtle version of a TN-panel color shift. I never have seen this on an IPS panel, though off-angles may get washed out (see Nexus 5/5X) quickly at 50-60°, they always retain their color, even if it lightens. Or, e.g., the Moto X Pure 2K IPS panel that I'm coming from has zero off-angle color shift, no wash-out, and just darkens a little even at 180°. This is my first AMOLED panel, so I'm not sure if it happens often.
If anyone can help me determine whether this is a defect or an expected limitation, that would be great.

I believe others are correct that it is the cheap screen protector. Plastics is refracting the light leaving the phone. Since blue light refracts more (the reason the sky and sea is blue). you will then to get more blue especially at certain angles.
I don't think tempered glass of the same thickness will make a significant difference but i do recommend getting a tempered glass protection because the cheap plastic one will surely be scratched very quickly. There a lot of things that will cause increased color shift, but I am not sure its a huge issue. I don't think accurate color is needed off axis. I could be wrong. I typically only look at the screen off axis when I am trying to take a odd angle picture or too lazy to move when I am in bed.
If any one does find a screen protector that distorts less please let us know.

The first thing I did was remove the screen protector, and I still notice a blue-ish shift at angles. It's minor though, and it's definitely not a dealbreaker.

AMOLED screens are typically like that. When I get on the bus and see people using their galaxies, it always looks cyan from an angle. LCD technology loses contrast at angles, whereas AMOLED has chroma shift.

Just to be clear - the color shift happens without any additional protector. Someone else used the word "protector," but I only have the bare Gorilla Glass in front of the AMOLED screen, no plastic or other layer added.
I see it as well with no screen protector on.

I never understood why phone makers use glass. Just make it plastic with a removable glass screen protector that the user can replace if broken. My GF dropped her phone, The tempered glass protector broke but protected the glass screen.
I do like that the S7 active has a plastic screen just wish all companies did this.
Hello,
I have the same issue with 5 devices I was testing. Every Axon 7 had the issue with the color shift from a red tint, to a blue tint when tilted.
Is there someone without the issue or is it really normal?

I guess it's the pentile arrangement, since blue subpixels are larger
