Non square pixels ?

I've noticed that Leo is somewhat wide, and still it has same resolution as other phones.
It has resolution 480x800, which is width=0.6 * height.
That huge Russian review states that Leo has display dimensions 88x56 mm. That makes it 0.63 * height. Which would mean the pixels are not square, it is 5% wider.
That is not much and it would be hardly noticeable. But if you rotate the screen, it will be 5% in other direction, and the difference would be 10%.
Question is .. is it noticeable ?
At least it should be measurable. If you have Leo, could you recheck my theory ? Display perfect circle or square (such bitmap should be easy to make on PC), and use ruler to measure the width and height on Leo's display. Also try that in landscape mode.
If indeed the pixels are not square, I'm interested how is it noticeable. Especially on people it should be visible, especially if you switch from landscape to portrait and back. On portrait all should be wider, on landscape all should be thinner.

88x56 cant be correct cause it is not 5:3 and this also imply a 4,1" display and not a 4,3" one ^^. Conclusion: The values arent correct . The pixel are squared.

It's probably not that noticable, or rather doesn't matter as soon as you get used to it. The pixels on my laptop (Thinkpad SL500) aren't square either, but as soon as you get used to it it's no problem

Good point. Still .. what is the real display size ?
Leo surely seems wider aspect ratio then my current Xperia, which has the same resolution, and perfect 0.6 ratio.

I searched for some pictures on google and measured the aspect ratio on them, and it looks ok. So the impression comes probably just from the fact that Leo does not have hardware keys and the part above display is quite short too.
Good ! Eh .. now I simply HAVE to buy it, right ?

to be 4.3in diagonal (109.22mm) AND be square pixel at 800x480 the lcd size has to be 93.65mm X 56mm.
Is is that? i don't know, but it would fit in the frame reported at 120.5mm x 67mm.

I just held a ruler next to my screen and measured the screen. The size is 56x94. The are approximate sizes no exact measurements...

Thanx, that makes this non-issue.

Reference for display hardware quirk

I just wanted to post this for anyone who is overly anal about small problems with display technology, like myself. After owning the G2 for a week (Verizon)and finding some of its display flaws, I was able to confirm all of them with 3 other Verizon units.
1. It seems that the bottom left corner area (in portrait), radiating out maybe an inch (and a little further up the left edge, most easily seen by using the default white soft buttons and comparing the left and right corners) is a little bit cooler in color (blue hue) than the rest of the display. Most people probably won't notice this, but at least 3 of these phones were from different batches.
2. The top edge of the display (near the camera) is a bit brighter than the other edges, a characteristic that many edge-lit LCD phones seem to have.
3. Yes, the grid of dots on the display are normal, but if you can see them with the display on in a poorly lot environment, you probably have either a bad revision of the digitizer hardware (one if the 4 I looked at had this problem, not the one that I own).
4. Like any display, the calibration range varies widely between panels. My phone appeared to have a warmer calibration than the other 3 (which I prefer), one of them appearing almost as blue as my old GS3. So, if you think your display is too blue, it probably is. For reference, by iPad appears to be slightly cooler than my G2 unit.
If you're like me and at times have been a chronic phone-returner for defective units when it may have just been a defect with the technology used in a particular model (or just a product of bad QC), I hope this helps.

I have this on mine. It also appears that the right side is more yellow than the rest of the screen as well. This is normal for the Verizon version then? Im usualy picky hut its a huge quality improvement over my old dna.

Screen coloring green/blue/etc. at slight angle

There seem to be quite a few Note 4's being sold globally that suffer from serious screen coloring (color shifting) when watched from close to a normal viewing angle. To get an idea of the scale of this problem this topic contains a Poll.
This defect is most easily noted on a bright white screen (www.google.com, "Dead Pixel Test" app). Even at a slight angle (=20"-30" from dead straight) the screen will show a clear blue, green or red colored haze. The screen on a properly built Note 4 stays (close to) white, even at a wide angle.
Please let us know if your Note 4 suffers from this phenomena beyond a trivial degree or if it doesn't.
Also be aware to check for this defect BEFORE you root your Note 4, as Samsung will object or even prohibit you to exchange your device for a better model.

I don't think there is such a thing as a "normal" Note 4. Every AMOLED phone from Samsung varies from unit to unit. I remember finding exactly the same differences between two Galaxy S3s where one had a tint horizontally and the other had a tint when angled vertically. Interestingly the phones with the greatest colour shift are usually the ones that go brightest when looked straight on. Either Samsung is making these phones in multiple ways from multiple factory plants....or for whatever reason using different materials (such as polarising materials) in the top layers of the screen.
Although I didn't check the tint on a second Note 4 I tried, I did notice that mine was obviously brighter at all points on the brightness settngs bar!
Either way, while bad uniformity is definitely a defect....I think this off-axis viewing tint is not. If it was a defect, it would exist with Note 4 only and not all the Samsung phones I have seen to-date. BTW my Note 3 also tints when viewing at an angle but a bit less than the Note 4.

I never had this phenomena with my 5 previous Note or Galaxy S phones, nor on my Samsung Tab S 10.5's. I did have multitouch issues on my Note 3 and 2014 Note 10.1. Seeing the screen of the Note 4 is plenty bright I don't care too much for the "more brightness" bonus, if it were applicable here. I compared my unit to a random store unit and in direct comparison I much preferred the store model. The white screen already looked a bit 'off' on mine, and the store model did not have color shifting at all.

What are the chances of both my Note 3 and Note 4 having the same "fault" though? My Note 3 goes bluish off axis, my note 4 goes greenish. Both screens are still perfectly readable at any angle, and only colours that noticeably shift are white/grey. Orange still looks like orange, red still looks like red.

I think it depends on the amount of color shift. My Note 4 has a clear blue haze even when looking at it close to dead straight. I watched a snowboard movie/documentary and snow went definitely blue with only a shift of 20-30 degrees.

It's really good news to know that many devices don't have the blue tint when shifting! If mine has it I'll definitely send it to maintenance. I guess repairing is better as I can look at the device at their facility and not accept it if I don't like the results.

It is really hard to be sure we are all seeing or evaluating this the same way. For example, if I display a photo with many colours, I see no shift at any angle. White is the most obvious and you need "lots" of it like a www.google.com screen to see it. I would say I am fine for 20-30 degrees before it starts shifting. I think you may have been a bit unlucky in happening to choose a snowboard documentary rather than Iron Man 3 or something like that etc! Then you might not have noticed it

I voted "No" because the poll asks whether the screen color changes at a "SLIGHT" angle. While mine does not, at a larger angle the screen does show blue tinge that increases with the angle.

I have this too, its normal?

I have the same "issue" actually it was the first thing I realized when I turned on the phone for the first time. I haven't even realized it with my previous used galaxy S5

It's probably caused by some coating layer. Nothing we can do about it, doesn't distract me much in a phone anyway. The screen is lovely apart from that, the black level made me almost cry when I compared it to my LCD TV. I so want an OLED TV now. Shame they are so expensive.

Mine does this:
https://www.youtube.com/watch?v=aVrm73sAnUs
Is this a faulty display or is it just the way this display works?

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 get all the colors green a little blue and a little red it actually seems to me like a [email protected] rainbow I don't mind it much because it doesn't distract me much but I will pay more attention in the near future before buying a Samsung phone again...

No solution to this feature?

It is not repearable by software or external means. Well, maybe a heater could do something, but I am not gonna try.
I sold my Note 4 and now have the Note Edge, which luckily has much less issue with color shifting.

While looking directly mine is red at the middle of the screen. While rotating, the red tint is appearing at the top or bottom of the screen according the rotating direction. Also Bottom part of the screen is also less white than top.

Forgive my not reading the entire thread as it's late and time is an unusually precious commodity lately...
My screen does develop an extremely mild hint of a color shift at slight angles, but I don't notice it unless I look for it. However, at extreme angles (at which I never view the screen, like greater than 75 degrees away from dead-on perpendicular to the screen surface) I do see not only greenish/bluish (almost like a faded teal) but also a magentaish hue. I suspect in my case it's a result of the manufacturing and tempering processes of the glass. LCD panels exhibit something similar when viewed through polarized sunglass lenses, but this is not the same: LCD panels have a nearly random-blob appearance where on this Note 4 it appears in bands running along the vertical (when viewed in portrait orientation) axis of the screen. At worst, I can make it greenish on the left side and magentaish on the right by viewing at around 70-80 degrees off perpendicular, so admittedly I have to hold the phone in such an extreme position to see this that I don't consider it a defect per se.
HIH.

Mediocre - Subpar screen quality

My 32/3 Mi Max just arrived today, not too happy with the screen. It seemed so dull, some leaks on the edge. No competition between AMOLED screen and this. But the 7' LCD of 1920x1200 mediapad X2 is still a height better than this. Heck, even redmi note 2 is better. A little disappointed, glad I didn't go all out with 128/4 version.

Mine isn't that bad. Download Color Changer Pro from the Play Store. You can increase the saturation and colors in it. Mine almost looks as good as an AMOLED now minus the blacks.

The screen protector you have reduces screen quality especially black levels. 100% the cause. Most of the full cover glass for 2.5d screens does not actually adhere to the screen reducing contrast.
The screen quality is v.good although it uses software contrast boosting to make the colors nice, which can crush some details in colors.
Take off the screen prortector and show the same photo, you will see the big difference.
Btw what case do you have?

I've made some comparison photo from some of my available devices on hand. It's horrible, They're definitely cutting corners on the screen. Even my $60 Alcatel phone looks better. My Mi Pad, and Redmi Note 2 have the same "washed out tinting" issues, but this is definitely worse than that.
Just for a note:

Did you read what I said about your screen protector.
The screen is IPS, there will always be changes in brightness when viewing off axis. It's called IPS glow. Depending on the screen, you will see it more from different angles. Mi Max might look better at a different angle than the other phones.

Now you can see the contrast is increased and black levels are better.
This is why I hate phones with 2.5d screens. You can get these full cover protectors which reduce quality or normal glass protectors which don't cover the screen fully. There is also tpu screen protectors which will cover fully without reducing quality, but they feel a bit rubbery and are hard to apply.

I forgot to put the note on the bottom, I took off the screen protector.
All LCDs have that bleeds, glows or whatever you want to call it, I'm well aware of that. But, If you need to put your phone in an angle to get correct color reproduction, i think it defeats the purpose of "IPS" display in the first place.

IPS screens don't really have a purpose, it's just a screen type. Every type of screen has its flaw.
Amoled has image retention and must use pwm to reduce brightness. Some people notice the flicker/eye strain from it.
TN panel has inverted colors instead of ips glow. IPS still has better viewing angles and IPS glow is only noticeable at certain angles.

I have to agree that the full screen coloured screen protector is POS, just realised that it doesn't have any glue in the middle, making some gap between the screen and the protector. Gonna order some better one.
Besides the screen, it's a solid good phone I reckon. I get more than what I bargained for because it's really is an inexpensive phone.. too pampered by AMOLED I guess.

The battery life is amazing. I recently got the 3/32, currently 8.5 hours SOT and 40% battery left.
Hows the miui 8 rom? I've left mine on miui 7 for now as I've read some bad things about it on the miui forum.

There is some full coverage protectors with glue in the middle, at least for other phones. Not sure if there is one for mi max but if there is, they are very rare.

It's fresh out of the box. Haven't really tried anything yet, but I'm on 8.0.1.0 apparently. I'm not sure about the battery life.. I'm more than happy to get 6.5hrs sot. My daily driver is iPhone SE, hands down its a beast of a phone, 9 hours on time give or take.
I just ordered Nillkin glass protector for my mi max, kind of expensive, but can't go wrong with that one. Please share with me if you found any good full screen glass protector.

The big draw of the Mi Max screen is the size, not the color accuracy or black levels or brightness. It's an average screen, not mediocre like a lot of cheap Chinese Android junk but not as good as an LCD on a flagship device. AMOLED is on a different planet because of the crazy saturation and inky blacks. I've had a few phones with AMOLED and although they're great for viewing photos and videos, they're not good for web surfing or working with documents because white draws more power. I didn't have any issues with burn in though.

1. The photo attached in the first post doesn't actually have the mi max in it. I suggest you remove it.
2. Second, the comparison album you made on imgur has software buttons and doesn't actually show that it's a Mi Max, while the separately attached photo in that same post has the xiaomi rom running. The separately attached photo clearly shows its the Mi Max and the display looks great to me with no issues.
My personal experience is also that the screen is great and I'm not sure where you're coming from...

In the first post, Mi Max is the middle phone. The user has installed a full coverage black glass screen protector which reduces the contrast as there is an airgap between it and the display.

I thought long and hard about wading into this thread, but after using the phone for a week I figured why the chuff not.
So, yeah, after 7 days use I've got to say I think the screen is pretty great! I haven't seen any hint blue tint I've read about in a few reviews, although, my device is much newer than the first batches and preproduction models, so that could explain it.
It's not as punchy as an AMOLED, but AMOLED colours are often way inaccurate. Which brings me to my next point, I find the screen pretty spot on in terms of colour accuracy (visually speaking at least, I've got no idea as to the reproduction of the panel on a spec level). It's definitely an improvement over my Meizu M1 Metal.
For the money, it's hard to fault this device. It's by no means perfect, but it's 1/5 the cost of a Samsung Galaxy Whatever.

It is a bit on the blue side but just a bit & you correct it with enabling reading mode & moving slider to the beginning position.
Did my own view test today by using MX player & putting it in to the 32 bit RGB display colour format and then I played a 10 bit Hevc movie. Well the display is quite good but nothing mind blowing. Luminance is an a down side required for something like HDR but it can pass presumably if you use it in controlled darker environment. Actually with brightness set to 11 out of 15 possible (which translate into 73.3%) its good enough but if you go over that contrast and with it quality begins to go down drastically, 12 (80%) is top & even that I would call a compromise. Don't be missed by this for a mobile phone LED display this one is perfectly fine, not a stellar one nor the best one out there but perfectly fine. The little more brighter displays won't make much of the difference between 450 & 550 nits their is little to non difference you will be able to see in this particular case regarding LCD's, next category should be a 700~1000 nits but mobile phones & only couple of them are stepping in lower margins of that category.
At the end I just can't not to wonder if the guy who did a calibration of the display had a little problem with its eye sight because you see as much a display is on a cold (blue) side & that is minimal a tad or two the photos (with main camera) are proportionally on the opposite warm (yellow) side.
Best regards.

Anyone have both S10+ and A70?

Hi,
I have an A70 but am considering getting an S10+. I'm curious how the screen width of the S10+ compares to the A70. I know based on specs the S10+ is narrower but, given the curved screen, I'm curious how the actual screen width compares between the two.
If someone has both, would you mind posting a picture showing the screen sizes compared? Maybe with them laying top to bottom?
Thanks in advance!

I don't have an A70. I do have the S10 and S10+ though. I can tell you, the S10+ is around the size of the Note 9. With a 6.4 inch screen, it's pretty massive even with a case on it.
