Hi,
I have noticed, as I drive a lot and use the phone on the dashboard with GPS, Spotify etc, that whenever it is sunny and I wear my sunglasses (Ray Ban with polarization, my screen becomes completely black. I know this is very common with LCD screens.. but I thought that most phone companies these days would take it into consideration that many people use polarized glasses.. at least it seems Apple does, as on my older iPhone 5 this did not happen.. and it does not happen with my iPad either for that matter.. is there a way to get a screen protector or something to reverse the polarization effect on my HTC screen? As I hate having to hold it in a 45 degree angle to be able to see what is on it.. and I cannot do that while driving, as I do not like touch the phone when I am driving.
Does anyone know?

Well,i noticed some odd behavior the other day with my phone laying on my desk at work. It was completely unresponsive. So I was just fooling around, laying the phone on my bed, same thing. I realized that unless my other hand is touching the phone, the screen is unresponsive. Think this is some sort of grounding issue? It isn't a big deal, but I have never had this problem on other phones. Anyone else have this problem? Try sitting it flat on a desk without touching the body of the phone and see if the touch screen functions.

Dont quote me on this but i read on how touch screens work and it basicly like you said the screen has a charge and when you touch it it slightly changes the charge and thats how the cpu monitors the change and tells the screen to act the way it does. But i am not sure why the screen gets less responsive when your not holding it in your hand. It happens with my G2 and my G1 so nothing new but maybe some one can actually explain what is going on.
Fear the static
The answer is quite simple; it's cooler outside so there is less humidity in the air. With lower humidity you have a higher static charge on your body (hence why you can zap someone more easily in the winter than the summer). Since the screen is capacitive (relies on small changes in the charge on the top surface to know where you are touching it) and you have a larger charge on your body, the digitizer sees it more like you bringing three or four fingers in close proximity to one spot. The reason putting both hands on it works is because you now give the digitizer a reference charge to distinguish and ignore.
TL;DR - Winter static makes screen think you are ham-fisting it.
Solution - use hand lotion to help dissipate your body's static charge from your fingertips, just don't use so much that you end up leaving greasy streaks on your screen. If you do, wipe the excess off of your hands with paper towels until you don't have lint tracks in your hand, TP is good for this.

I can confirm this "issue" or behavoir. It happened to my phone exactly like u described. I dont know if this is a common thing for capacitive devices or not but it does happen to me.
Oh well, i guess i should stop being lazy and pick up my phone lol.

I 2nd that statement and a +1 on solution with lotion! lol
Now i will begin to tell my gf how the Screen isnt HEAT sensitive and why during the winter time with cold hands it responds differently.
i did notice this behavior the other day, and to be perfectly honest it scared the tar out of me, but then as soon as i picked the phone up it was fine again. i guess you really do learn something new every day, i always thought the capacitive screen reacted to heat, but i guess not.

****, do I have to go buy hand lotion now? Anyway, thanks a lot.
Does all capasitive screens react like this are some phones just more prone to it?
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.
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.
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.

Hey guys, just got my S22U the other day (along with the wife) and have to say, great phones. Took mine out today with my sunglasses on (which are polarised) and noticed a big thick line in the middle of the screen while looking through the glasses. Take them off and you can't see it. Tried it as well on the wifes phone and same thing. My S20U never had this, was wondering if everyone has this issue on their handset or if it's just limited to a certain batch?
I took a photo with the polarised glasses in front of my wifes camera to show what I mean
You do realize that lcd displays work by polarization, right? They may not look correct through polarized glasses.
Yeah I do, I've never had a panel this drastic though which is what caught my eye (no pun intented)
