Display almost unreadable with polarised sunglasses - Samsung Galaxy S10+ Questions & Answers

I'm using the S10+ for navigation (among other things), but have notice that I can hardly read the screen with polarised sunglasses. The screen looks mostly blue and has very low contrast. Never had this with any other phone. Are there any tricks to make this work? Or do I need to get new sunglasses?
Thanks

Apparently it's the screen protector... Peel that off and your good to go?

Thank you. I will give that a go.

Screen question

Hi,
I've watched numerous videos of this phone, and it looks as though the screen on the HD2 is quite reflective, has anyone had an issue with this?
Cheers
When using it in sunlight, you can see yourself. If you don't mind seeing yourself or what's behind you, then it doesn't cause a problem. Just think "any other mobile phone screen". Nearly all phone screens are glossy when off, it just dpeends on how bright you set the backlight. Set your current phone's backlight down a tad and you'll probably get the same effect. Then you can decide if it worries you.
You can also get screen protectors that are polarizing and reduce glare ......

HTC HD2 Screen Brightness

Am I the only one having trouble with HD2's screen brightness ?
I work in a very shiny-sunny environment (I'm a ski instructor) and I can barely use the phone when I'm working. I manage to use the basic functions, but watching a video is impossible, I just cannot see a thing !
I compared with a friend's Iphone a few days ago and it seems Iphone screen's brigthness is much better. (or is it the material used for the screen itself?) Even though it's sunny, the Iphone shows nice colors and images, when the HTC darken everything, coupled with reflects making the whole thing unusable...
I'm already using a 100% brightness all the time but it doesn't help much when the light is strong. Though it helps draining the battery quicker...
I don't want to start any sterile debate Iphone-HD2, I'm very happy with my HD2. Indoor the screen is just great. I just have that one big problem in my everyday life with that phone...
I have no problem looking at the screen under direct sunlight with auto-adjusted screen brightness setting. 100% screen brightness should not be a problem for me.
Did you use any screen protector? Perhaps different type of screen protector might affect the brightness of the screen, at least by minimal amount.
Mmmh
Maybe the snow reflection and the very high luminosity around here is responsible for this I don't know.
I've always had that problem with my HD2. Yesterday I installed a Zagg Full Body Shield, and it's even worse ! Though there are less reflects (the screen is not so shiny anymore), the screen protector make it even darker.
I'll remove that screen protector, see why here if you're interested : http://forum.xda-developers.com/showpost.php?p=6255312&postcount=57

Of course you don't have a problem with viewing your phone outdoors - you live in England.
try an antiglare screen protector, do you have your brightness set to 100%?

Your S4 screen with polarized lens sunglasses

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.

The Z2 screen is polarized (can't be seen in landscape with polarized sunglasses)

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:
http://youtu.be/kSWo7yLdfwU
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.

Exactly! I've hated the camera on my M7 since day 1 and I was excited to finally upgrade to a phone with a high quality camera. Little did I know at the time the Z2 would also be useless on sunny days for taking photos

That's pretty interesting, I never really knew how that worked, thanks! I have noticed in some cars I couldn't see the nav screen with my sunglasses on, and I just thought it was a poor quality screen, luckily in my Jeep there's no problem at all though. Now I must find a phone with a legible screen for taking sunny day photos.

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.

Increase screen brightness?

I recently got an Eonon GA8163 unit for my mazda, and for the most part its okay.
I'm really considering returning it because of the dim screen during the daytime. With sunglasses on, you can't see it, and without its still pretty dim.
Is there anything I can do to help it out?
I have everything set at max brightness, white background, but was wondering if there were any more advanced work arounds.
If there isn't anything else I can do, i'm tempted to return the unit and go with a standard brand name double din unit.
Hi there is usually a resistor or a preset resistor that you can change or adjust. But you will have to find the location of it on the board. If you have the PCB layout it would be much easier to locate it.

Thanks !!! That seems to significantly make the screen BRIGHTER. (at least it looks brighter as I look at it at night .. will see what it looks like once the sun comes up).
If it's still not bright enough, here are a few words of encouragement :-
While there is no User adjustable CONTRAST, it would seem that even at FULL Brightness, Blacks are still a full BLACK, and are not washed out and starting to become a dark gray.
This would indicate, that if the Backlight was BRIGHTER, it may still not burn through a Black section, but a white section would brighter.
So all that is needed is a BRIGHTER BACKLIGHT.
I suspect the current Backlight is running near maximum brightness, otherwise the manufacturer would set it up higher -- so what is needed is an Upgraded Backlight (and possibly associated Backlight supply).
A better backlight would cost more in production, so to keep the cost down, a manufacturer will fit a backlight with the minimum brightness (ie Cost), that they can get away with.
However, LCD displays can have potentially have very high power Backlight in them, so that they can be readily readable in BRIGHT sunlight. (if battery power is not rationed -- ie in a Smartphone). Car has a "BIG" battery, so a more power hungry BRIGHTER backlight would not be an issue on car battery life.
Next time I have the Unit "out of the car" I intend to take a look at the backlight, and research the possibolity of fitting a significantly brighter backlight. It should be possible to fit one that would be so bright, one would never want to run it at full brightness, and it would be blinding, even in direct sunlight.
Having upgraded over 200+ Industrial LCD display to brighter LED Backlights, I believe that the above might be a distinct possibility, at a reasonable cost. The only restriction might be how easy it would be for the average user, to carry out the upgrade, without damaging their unit.
If this works out, I will post some pictures and details of the upgrade.
The GS2170B is a great unit for it's price, with a very good response speed. It's only major failing I have experienced, is a sub-optimal Brightness.

Thats awesome! Have you looked into this yet/have any luck? I have a GA2170 as well which is just a bit too dim to be easily seen in daylight (night time is fine). Also, has anyone bought an anti-glare film to cover the screen? I feel that that would help immensely (mine is so shiny that any sunlight in the car at all renders it nearly unreadable).

WARNING? Long -- do not read unless you are really interested in my personal thought on this subject.
I have taken the HU apart to check out the LCD panel part. It is custom to that model, and not a readily replaceable display to a brighter panel.
So I have put modifying it on hold, and have explored some other ways to improve the appearance of the display.
(1) Tinted my Windows (they had no factory tint) .. That helped in so many other ways as well.
(2) Diagnose what was actually being reflected, which was interesting and not what I had expected.
The reflection you see when looking reasonably straight on into the display, is the reflection of what is directly perpendicularly in front of the display.
If you look at a modern car HU, they now tend to be mounted quite high up, but no longer is a shaded Tunnel/Hole.
Instead, the are mounted at an angle to point up at the inner ceiling of the car, which optimally is a dark color, and therefore is not throwing much reflective light onto the front of the Glass.
I had always incorrectly assumed, it was the direct sunlight, shining through the windows onto the panel, but this is only part of the reflection problem.
If you get a sheet of white paper, and move it around about 2 feet from the display, you should clearly see, that when you get the paper into a perpendicular position in front of the display, that the reflection from that white paper is the major cause of not being able to read the screen ,
Replace that white paper with a Mat Back sheet, and the display becomes amazingly more readable,
This is why the manufacturers now slant their units to be pointing up at the ceiling, between the drive and passenger seats.
Anti Reflective Films: I have yet to find a decent, effective, anti reflective film.
Most being sold are to help prevent scratch damage to the front glass, and if anything, are actually more reflective than the glass itself.
Manufacturers can get a pretty good anti reflective coating onto Glass (example, a good Picture frame glass, or car dashboard glass), but it must be a lot more difficult, or cost prohibitive, to get a decent anti reflective coating onto a cheap $10 screen protective film.
Since my unit is a replacment for the 2din radio in a 30 year old (Classic ?) car, and is located low in front of the gear level, and not higher up as in most modern cars, I have made compromises.
Even it it was Highly Bright & Readable, looking down at it is a major distraction of taking your eyes completely off the road, so I have concentrated now on making the unit more controllable by the addon steering wheel Buttons, and with Google Assistant control, that there is now seldom a need to even look at the unit, especially for any length of time, or to perform any complex, distracting operations.
This approach is working well, and as time goes by, I am finding I am getting far less concerned about the lower brightness display.
Also, since my Unit has Video Out, I am considering mounting a small Video screen up in my Instrument panel (Probably covering the Tach, and having a nice bright display there that I can see while still looking ahead through the windscreen. The other option is a nice bright Heads Up display, throwing the Information onto the Windscreen, just like the Air Force Fighter Pilots have in their jets !!

Thats awesome! Have you looked into this yet/have any luck? I have a GA2170 as well which is just a bit too dim to be easily seen in daylight (night time is fine). Also, has anyone bought an anti-glare film to cover the screen? I feel that that would help immensely (mine is so shiny that any sunlight in the car at all renders it nearly unreadable).

My GA2170B came with a film already on the screen (I think that was just a factory/shipping anti scratch protective film), and a separate, user installable protective film, that claimed to be anti reflective, but did not appear to do much to top reflections.
Manufacturers poor attempt to compensate for what they must realize is a "cheap sub standard brightness screen" -- but you get what you pay for.
You want something really nice and high end, be prepared to drop $1000+
I wish the glass on the Eonon was like the Glass on my 30 year old car's Instrument panel.
It has NO RELECTION at all, and when it is clean, you cannot even see that it is there. It looks like you can just reach out and physically touch the needles of the Gauges, even when there is bright sun shinning in directly onto it.
All the sun does is to make the Needles and Gauge Scale brighter !!
Thanks for the update! I guess I'll have to keep using it as I do until anything else changes. Cheers!
