if u were discussing about the ppi on android or IOS phones there were no problem but its Z30!its different from all!its BlackBerry!other systems just turn around themselves.
Astro boy, 05 May 2014I agree higher PPI of around 400 would be nice to have but PPI would only matter to me if its ... moreI seen that before and i dont question BB10 being the best or the many great things about Z30 but for me the PPI is a dealbreaker. Im fed up with Androids and Googles crap but a high PPI is too important for my personal preferences.
Interesting thing is that similar discussions arouse in late 2009 and early 2010 when iPhone fans claimed that noone needed the high resolution of Nokia N900 (only 267 PPI) because iPhone 3GS had more pixel density than anyone needed (165 PPI). It was, in retrospective, ofcourse insane to say that 165 was more than enough, everyone could see that the high PPI (by the standards of that time) made N900 the king of webbrowsing. Today no Apple fanboy will say that 3GS was superior to N900 but at the time they defended 165 PPI as if it was the holy grail of smartphone displays. History is now repeating itself.
Anyway, lets not go too deep into this, lets just accept that "acceptable PPI" does not mean "the best". The question is what is acceptable and for me 326 is not, but for now i can live with my Z10 at 355 even if its too far from optimal.
Also, mathematically, the PPI difference is much bigger than the PPI numbers suggest. Its natural to assume that the difference between 165 and 267 is "only" 62% (267 divided by 165) but in reality it is 162%. The correct solution is 267 squared divided by 165 squared, since PPI is a one dimensional property of a two dimensional display.
Another interesting fact is that our fovea has a resolution of 180,000 cones per square millimeter, the square root of 180k is 424, multiplied by 25.4 millimeteres per inch = 10,770 ppi. But thats just a theoretical number, the eyes focal length (highly individual) reduces that number to below 1000 for the best eyes.

Astro boy, 05 May 2014One more thing i would like to add is below link

"technically the screen won’t be sharper than it needs to be until you get to the 500 pixels per inch range."
Im only asking for 400 PPI, though 500 would be nice.
By the way, i admit i dont find any advantage of 440 over 326 with photos and video, the culprit is small fonts. And 8 is not small, in fact thats the default size on my Z10. I have tested it on 5 and even then 355 PPI is not bad at all, but in the web browser they easily get much smaller than that and then it easily becomes garbled. Go to desktop version of the frontpage of this site and read it on your Z30 when zoomed out and then imagine that it looks nearly perfect and fully readable on an Xperia Z with the exact same display size. Huge difference.

All of us would admit that there are people who can run faster t... moreDuring 2013, Insight Media has focused more on the development of mobile displays in response to the increasing market importance of these displays. After the first introduction of a ‘Retina’ display in 2010 by Apple, many discussions of the meaning of the term have produced a variety of views.
The term ‘Retina’ was coined by Apple as a trademark and was meant to differentiate their products from other Smartphones with lower resolutions. At that time Smartphone displays were rather low resolution as no phone manufacturer saw any demand for higher resolution. This perception changed rather quickly after the release of the iPhone 4.
Apple used the term as a description of the limit of the human vision system to resolve single pixels. In their opinion at a 10″ to 12″ distance the 3.5″ display in the iPhone 4 with 960×640 pixels was right at that limit. This resolution equated to a pixel density of 326ppi.
Screen Size vs. Pixel Density
The chart shows an area in which most of today’s displays fall. There is of course a wide variety available in the market. While larger screens are falling into a close range of pixel density, the smaller mobile displays show a much wider disparity. Some typical displays are shown in this chart for an easier comparison. Of course we have to keep in mind that larger displays like TVs are typically viewed from a larger distance.
From a scientific perspective we have to deal with the functionality of the human vision system to understand what the human eye can resolve and what not. If we try to define a ‘Retina’ display as the limit of what a human can resolve we have to deal with several parameters that are independent of the actual pixel density. There are simple parameters such as distance to the display, but there are many other parameters that are more complicated. For example, the contrast ratio and absolute brightness influence the visual acuity. Then there is the distribution of visual acuity throughout all people. What one can resolve many others can not.
In the end, the discussion if a display is a Retina display in the meaning of Apple, depends on what percentile of the human population is included. What percentile should we chose? Does it make sense for a CE brand to base their product on a 99.9% percentile? This would mean that o.1% of the population is able to see pixelation in the display, while the other 99.9% do not. Just for fun, with a population of 7 billion people, 0.1% equates to 7 million people.
If we would all agree and define a certain pixel density for a specific type of display such as a Smartphone display for example, as the limit of visual acuity, we all could live happily ever after and all manufacturers would stick to this pixel density.
However, this is where it gets really confusing. At this point in time, the resolution of the display screen has nothing to do with fulfilling the idea of a Retina display anymore. It has become a marketing tool in a similar way as the screen size of the Smartphone. CE product marketing is often based on technical specifications, maybe because this is the way the design engineers communicate.
In the last few years, the 100 ppi mobile phone display has given way to the 400 ppi full HD display in the latest Smartphone models. As a marketing manager you have to ask yourself, if a 400 ppi Smartphone sells better than a 100 ppi one, how much better will a 500 ppi Smartphone sell? At this point ppi as a measure of viewing performance becomes irrelevant, the ppi number is a pure marketing tool.
If this trend continues, display technologies that can provide insanely high ppi numbers will have an advantage in the market place. They may not necessarily make sense from a technical standpoint, but they will make a lot of sense to the marketing manager. This will only be true until we can come up with another specification number that can be increased and used as a marketing tool. Then, and only then will we go back to the ‘one resolution fits all mobile phones’. – Norbert Hildebrand

All of us would admit that there are people who can run faster than us, who have more durability, have bigger this and that bodyparts than us and can lift more than us, be better than us at boxing or whatever fighting sports it may be, and also some can calculate faster than us and write better, but it seems its hard to admit that they can also have better eyes than us, why???
Just as our muscles and whatever was created very unequal our eyes and ears also were created equally unequal. To get an idea, do some research what is 20/20 vision, you'll be surprised, 20/20 is actually a very poor vision and most people dont get that poor vision before they are between 60 and 70 years old.
Apples Retina were defined based on a 20/20 vision! it only equals to ONE arcminute, ONLY ONE, while the resolution of the human eye is actually 3 times higher at 0.35 arcminutes.

I got rid of my Galaxy Note 2 because i couldnt stand the terrible pixelated display at only 267 PPI, it was useless for web browsing, it was terrible.
Font size 8 is very big compared to the sizes im talking about here, but i can still read them, IF the PPI is 440.
Anyway, im sure BB will release phones with 400 PPI or more, i just hope they will not all be big misfits, im through with big phones, i change to iOS or go back to Android if BB fail to bring a considerably upgraded successor to Z10 this year.

Z30 is the Ultimate device i was always looking for.
What i like about Z30?
1] Build Quality
2]BB10 OS(No crappy notification icons on top of screen like Android, No Lag like Android, No itunes required like iOS, No fixed toggle menu like iOS, no Blue tooth restriction like iOS, Can have a wallpaper which is not there in Windows Phone OS, Can record calls which i cant on Windows Phone) Hub feature with priority hub is amazing.
3]No Menu buttons and back buttons(gesture based).
4] Amazing virtual keyboard(Best in the world).
5] Excellent music quality(even beats the iPod)
5] Loud Speaker (Never miss a call)
6] Fantastic in call sound quality (no huh huh..what what and say again say again)
7] Man this phone catches network signal even in my office elevator.(No phone did that previously).
8] Last but most important:- Its BATTERY(how can i forget it) NEVER SAYS DIE..(I used to keep a charger in my office previously for my samsung S3 and now believe me i charge once in 2 to 3 days not because i dont use much but because Z30'S battery is big and screen is amoled)
Love you BlackBerry.. Love you Z30
zahra, 05 May 2014if it has a excelent ppi then its battery wouldnt be like this like iphone...2D rendering is not an issue for power consumption, and 3D isnt really an issue also since it will very often load the GPU to the max anyway, if the resolution is lower it will often spend the same amount of power to render it at a higher framerate.
The difference in power consumption is so small but the visual advantage of 1080 is big on a 5 inch display.

Z10 is much better but still small text has too low quality and is hard to read without zooming in.

Been use Z30 for about a month.. i noticed some issue with this phone,
1 - When pairing with ear bluetooth device, the range that it can handle is shorter than other android or ios phone, more noise when theres a wall blocked. ( I have Samsung Galaxy Golden I9230 and Z30 paired with my Plantronics Voyeger )
2 - After updating OS version, when theres incoming call, sometimes i got stucked when i wanna slide to left ( to answer call ). On and off button wont work. I have to wait for the call end then i need to call the person back.
This is the only problem i have with my Z30. The phone is good, i love this phone.. hope theres an update to fix this.
