[Q] Polarised glass?

I am wearing polarized glasses, and noticed that glass on my Note is polarized too. You know, when you rotate phone and see different transparency.
If Note screen is LED technology, why polarized glass?
Sorry for my language, not native.

Confirmed !!! Tried it on Galaxy Note and yes it indeed changes transparency levels. I believe its more of a pixel shift effect due to pentile matrix display. Wondering if this can be used for passive 3D viewing experience on Galaxy Note?
As an added observation tried it on my nokia with AMOLED display without any polarization effect.

Waterproof-ness

How waterproof is the phone?
Can the touch screen be used underwater?
I know it can be used right after taking it out of water, but what about under the water?
Also can buttons be pressed in the water?
If not, will the phone be damaged if a water drop falls into the button space when pressed?

As long as all the flaps (USB/audio jack/SIM/microSD) are closed the phone is completely waterproof. It can withstand up to 30 minutes at 1m depth and water jets (shower/rain/...).
The touchscreen cannot be used under water, this is impossible with capacitive touchscreens.
All buttons can be used under water.

Actually I think screens are OK when fully immersed. It's when they have drops of water all over they have problems. This may vary depending on the touch panel in use but it's not impossible.

I saw some info "forgot where I found it" that the touchscreen of the Xperia Z/ZL supports pressure detection so if this is the case it might be possible to use it underwater. Will post the link soon when I find it.

Capacitive screens use conduction for sensing the touches so not sure about this.

Just wondering what's Throw?

The pressure sensor is not in the display but an actual air pressure sensor. Can be used to calculate at what height above sea level you are.
Capacitive displays work with electrical charges. There run tiny tiny wires over the display that detect when they are interconnected, which happens when you touch them. The problem is that when you use it when it is completely immersed, everything appears to be connected to everything. With drops of water it's possible to filter them out somehow (I don't know the details on this), but while fully immersed it's impossible to distinguish between what parts are being touched by water and what parts by skin accurately enough to provide touch input.
Throw is one of the marketing terms for Sony's DLNA stuff. You can "throw" images and video's to your TV and other devices over DLNA.

Ok... And I thought it was a pressure sensor on the screen I was planning on porting the python mypaint would have been great if the phone has pressure sensitivity.

Actually, pressure sensitivity on tablets and phablets (like the Galaxy Note series) is done with pressure sensors in the pen, not in the display. The display has some sort of electromagnetic resonance that (through induction) powers the pen and allows the pen to transmit back what amount of pressure is being applied.
One of the other ways that allows (limited) pressure sensitivity is by using a resistive display, and that isn't possible with a glass display surface. In addition to that, it is quite crappy.

I saw a video on youtube ( Can't remember by who, maybe Clove?) where they submerged the phone under water and the guy tried taking photos with the camera, the touch doesn't work at all under water. Makes sense with the explanations above, phone is meant to survive if it takes a dunk really

[Q] Is the screen used by xperia SP a pentile screen?

I see some report saying the TFT-LCD screen used by xperia SP is Pentile. Is it really the case? If so, is it a RGBG or RGBW PenTile screen? And can someone please post a close-up photo of the phone's screen?

Wikipedia only listed some example of PenTile screen devices that even Chinese WIkipedia listed more PenTile-using devices than English Wikipedia...
and i personally cant determine with enough confidence on whether it is or isnt pentile base on those photo at this scale...

[Q] Touch screen issues after replacement

hi guys
i just replaced my cracked screen with a new one (which seems not quite original!!) and i'm totally sure the the touch functionality is lower than the what it should be ( as of not original screen)
is there any way to increase the touch sensitivity to have a better touch on this screen?!!
another question! as you look at your z1 you will see the screen has a little redish tint in some angles and a unique pattern when the screen is off and the borders of screen is much more black than the screen. but mine,the screen is more black than the borders (the borders are not black as before in angles exactly like iphone 5 black )and no redish screen and no patterns! is this a terrible screen ?!
sorry for my bad english

It's same screen but from difrently manufacturer.
I have Z1 and my friend had one.
And we didn't have same screen, same camera, nothing. Everything was slightly difrent.
And yes, his scren wad redish, my is deep black

Screen Viewing Angles

So I just picked up my Note 4 last night. Coming from a G3. Screen is bright and colors are great. Liking the phone. But one thing that bugs me and it may just be me.. is the color shift during different viewing angles of the screen. Mine turn to like a greenish blue tint when tilted all directions. It's most noticeable on lighter screens. Darker colors not so much.
Does anyone else have this? Does it bother you? Should I go exchange?

Mess around with these settings first

Doesn't make a difference. Anybody else have this problem?

All the displays in the Note 4 have screen viewing angle issues. Some have vertical shift issues wheres others have horizontal shift issues and others have both. People tend to keep their eyes oriented on just the vertical aspect and look at their devices eye-on, a big factor as to why you don't read many others acknowledging this on their AMOLED devices (Note, not just pertaining to the Note 4). AMOLED has perfect viewing angles, the culprit is usually the digitizer and glass which are incorporated on top of the AMOLED screen. The digitzer and Glass are responsible for the color shift due to inorganic elements used to manufacture such components. I've seen red shift to orange when looking at certain Note 4's from a horizontal angle, and I've seen Blues shifting to purple from vertical angles, and I've seen worse in which a demo unit had pink shift and green and blue shift. A replacement is not going to help. The iPhone circumvents the screen viewing angle problems thanks to the separation between the LCD panel, backlight, and glass. Recently, Apple decided to combine the backlight and LCD, thus reducing 3 layers to 2, the results did not compromise the screen viewing angles. IPS displays are still a versatile choice when thinking about appropriate displays. AMOLED is simply good for folks that are addicted to saturated colors.

Never had any issue. When I first got my phone, when I viewed the screen from a heavy angle it had a bit of a pink tint on white colors, but that had gone away now.

Are you using any screen protector as well?
BTW,
There are several factors involved,
- Amount of Oleophobic Coating which distorts the actual colors discernible by the viewer
- The Digitizer
- The Corning Gorilla Glass
- And the amount of bonding used to keep the AMOLED display adhered to its bottom layer (Remember: Organic by Nature).

I have no issues. Looks amazing for me

Well after having it a few days.. it doesn't bother me much anymore or I don't notice it as much. Maybe it's going away. I had a few galaxy devices recently and I guess I never noticed. I'm used to my G3s ips screen.
