Screen Polarized? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Is the screen polarized or is it possibly my screen protector?
I was driving with the top down and polarized sunglasses and noticed I could barely see my screen unless I tilt my head to the right (horizontal mounted)
Just wanted to see if anyone else noticed this.

I wonder if it's the preinstalled protector. Wearing my sunglasses I can barely see the screen. My s10+ right next to the s20 is clearly visible aside from being a bit darker obviously. I don't want to tear off the protector to see if it makes a difference..

I've got a WS glass protector. I can view mine in either horizontal or vertical no problem. It disappears if I point the top of the phone at 2:30 or 7:30 only. So really no problems for mine.

Its your sunglasses not working well with that type of screen, i have Oakley polarised and several different smartphones have the same issue for me.

This problem has been an issue for years, a search online will tell you the filters on the polarized glasses negates the light on the cell phone screen and how to work around it, try turning your phone 90° and see what happens.

can't see screen very good with polarized sunglasses

Anyone else noticed that when you wear polarized sunglasses, you have to be off angle to see the screen of the 5x?
I got mine last week and it makes it real hard when wearing the polarized, at least the Smith sunglasses. Any remedies besides not wearing polarized lenses?
Same problem with the original Nexus 5. Fix is to get a different phone or glasses :/ .
Same here. Can't view the phone in landscape mode with polarized Oakleys.
Some screen protectors might be able to help this
No, it's how the screen outputs light and at what angle. There's no solution other than taking your glasses off or viewing the screen from a different angle.
That's what I figured. It makes it difficult when using the waze app while driving. Just have to look off angle and I can see it.
Just noticed it today with my polarized oakleys
Put a polarized filter on your car window, then cops can't see your phone screen!
Make sure it is oriented correctly for the way you hold the phone.

That's expected from a LCD screen.

Polarization on the screen?

Not a complaint or a request for help but more of an observation and interest in why.
Today we had sun.... yes sun in the uk.... I know it's very rare. Anyway I was wearing my sunglasses, went to turn on the screen and black... maybe I didn't press the button hard enough?.... nope nothing... what's broken already?
Took off my glasses and to my surprise the screen was already on. My sunglasses have polarized lenses and conflicted with some sort of polarization on the phone screen to let nothing through.
On my M8 the result was just a distortion on the screen not complete blackness.
Anybody know what purpose this serves in improving the screen?... other than making polarized glasses a no no when using it?

The M9 was polarized in landscape. No idea why they decided to polarize the 10 this way.
I had some problems with mine too, so I just threw it away

Every LCD panel is polarized in some way. Do the same thing with your old device and rotate it to find the angle.
That being said having this orientation polarized on the 10 is a pretty bad decision

Polarization allows lights of a specific orientation. Unpolarized light travels through an entire 180 degrees like in a circle. Polarized sunglasses use a polarized filter that's orientated vertically that allows only vertical (90 deg) waves to go through.
In a nut shell, the HTC 10's polarizing filter is orientated horizontally if you cannot see the screen in portrait with your sunglasses on. Polarization reduces eye strain by significantly reducing the number of light waves going through without affecting the brightness.
This orientation is actually a pretty good idea if you are using GPS in landscape mode or taking a picture outside with your phone. Imagine having to take your glasses off in order to take a picture or look at the GPS...that wouldn't bode well.

I'll take photos tomorrow but I can confirm the phone usable with polarised glasses if you have the sharp panel.
Polarizing in the portrait orientation also helps prevent texting and driving[emoji6]

sadly, it just means that people will text and drive with the phone turned sideways. also sucks if you are listening to a playlist and try to skip a song. Or walking down the street, or in a park.
Every device known to man is polarized, many vertically and horizontally. Why is it so talked about on the 10?

If I remember the s7 isn't. And some are radially polarised like the sony z2
Although all screens may be polarized, they can polarize it at a 45 degree angle to make the phone visible it portrait or landscape, but half as bright. Also, there is some type of layer they can put on top of the screen that would eliminate the polarization, or radial polarization. Kind of disappointed i can't see my 10's screen in portrait with sunglasses on.
Have tianma panel and lucky no problem about visibility tru polarized sunglasses

Sadly I think your glasses might not be polarised as I have a blank screen in portrait and u have a Tianma panel.

Thought so, then went to optic shop and asked to wear polarized oakley and Ray ban.
Went outside to check it out properly. I do have seen the screen both portrait and landscape thru glasses.
I can see mine fine in portrait but when I switch to landscape I get the vary dark grey screen. But that is normal any lcd screen should do this.

I have the tianma and the exact same experience as this. Landscape is clear and normal, portrait is dim, but semi-usable. Sometimes when reading something, i have to take my glasses off for a second to see better.
And yes, my sunglasses are 100% polarized. When I wear them while looking at my Dell laptop, the screen is COMPLETELY black. Which sucks pretty bad when I want to work outside on a sunny day.
Guess I'm not the only one. Walked out of Sprint store last Friday, got to car put phone in pocket and drove back to work. On way back into work, I got a text, with polarized oakley prescription sg's on, I could not see my screen. Kind of freaked out a little bit lol
I've been doing research and it seems a possible fix could be in using certain screen protectors. Looking at other phones that have the same LCD issues, it seems people have had varying degrees of success with either matte screen protectors or tempered glass screen protectors. Unfortunately, since our phone is so new, I haven't found a documented case of a screen protector actually fixing the issue.
Anybody have any more info on this? I've been wearing polarized sunglasses for years and I don't see switching to non-polarized as a viable option.

Screen Polarization issue

Is there a screen protector that improves screen visibility while viewing the htc 10 (verticality) with polarised sun glasses?
Thanks

I would say no considering what is necessary to rotate the polarization of light.
Is the phone screen polarized? I thought it was my screen protector was kind of irritated that I can't see my phone screen in portrait mode while wearing my sunglasses. Causes issues with using my phone as a navigation device in my car unless I rotate it to landscape or twist my head.
The screen is indeed polarized. I do not have a screen protector on my phone yet, and my polarized sunglasses do the same thing.
Polarizing a screen protector is an incredibly stupid thing to do, as it would lower the light output from your screen. No one would use a screen protector that dims your screen.

Screen warp?

My screen seems to be showing a bit of warping right at the bottom of the screen near the back and home buttons, right on the edge of the screen. Not so much that you notice but it warps the light if you use the screen to reflect the world, and only in that spot. Bit disappointed considering its a totally flat piece of glass!
Anyone else got this issue? Might get onto three about it. I'll see if it's widespread first.
I'll try get a picture later, or video if I can.
Warped like raised wavy or warped like wrapped screen that goes downwards into it at the edge? If either of those makes sense..
I saw that when in 120hz mode, but it looked more like an intended effect to me. It wasn't unpleasant in my eyes.
Also seemed to only happen on long scrolling windows. Short scrolling I could not see it.
I would say it's a pinch under the glass, but the glass looks fine, just reflections of the surroundings in the glass so right where the back button is. It's definitely not lifting and looks flat, but the light dances and create an almost m shape. It's far from anything serious, as you need to look for it, but just something to keep an eye on for early adopters.
I don't think the screen refresh affects it, as I can recreate with screen off.
Got pics from the screen, using my **** ipad camera. But you can see the warp. The white shelf is flat, being a shelf, so you can see it shows as straight up the screen then at the bottom forms an m shape.

Huh, i can see what your on about.
Mine doesnt have that, so maybe your device has a defect.

stains on the screen

Hello.
So I use polarized sunglasses and I noticed some stains in my screen. Only noticible with polarized sunglasses.
Can you test yours.

All I can tell you is not to wear polarized glasses - I had a funny episode when I saw my N10+ screen on bright sunny day while wearing new, highly polarized glasses: I went back home to take picture of that but the problem has 'fixed itself' and I still didn't realized what caused that until someone in the forum asked: did you take your sunglasses off? I'm a rational guy but this think made me look paranoid.:laugh:, but I felt embarrassed enough and asked mods to delete that thread, which wasn't fair to Samsung when I titled it something like "total failure of N10+ display"
Well, anybody can make a mistake ?
Those are stress patterns in the Gorilla Glass, normal.
The polarized sunglasses "see" them as the light coming off the screen is polarized.
Decades ago I developed the habit of tilting my head to view LCDs with my RX polarized sunglasses on. Now it's a learned reflex action I do almost instinctively.
Do the same when looking at a oily road surface... to gain an optimum view.
You can also view where the weak spot(s) are in tempered glass and clear plastics as they will be darkest. Helpful if you need to break it... or don't want to break it.
