Since 2010 and every few months there is a new smartphone display resolution, and with it come the discussions of the usefulness of these extra pixels, the law of diminishing returns, whether the human eye can tell the difference, and the impact in the GPU and battery life.
Phone makers keep pushing the resolution more and more, and to be a honest i am huge advocate of increasing the resolution.
But now since we reached 500+ ppi and QHD resolution, do you think this is the last upgrade or are we going to see 1800 x 3200 resolution in a smartphone in 2015/2016, maybe even 4K by 2018.
To be honest, the idea of 4K phone display is tempting, and in a 5" phone, that's will give you 881 PPI, that's about 3 times of the pixel density of what claimed to be the limit of the human eye for a device held 10 to 12 inches from the eye ).
For me personally i doubt that the 300 PPI is the human eye limit (for a device held 10 to 12 inches from the eye), as -many before- me pointed out, and as long as i can tell the difference (i am able to tell 1080p from 720p , and also 1440p from 1080p) i am all for it.
What do you guys think the industry is going, is the resolution war will continue, or is QHD is the last upgrade at least for a while.
Display resolution milestones in smartphones (please correct me if i have made any mistakes):
2004: 320x320=~0.1MP (Palm Treo 650)
2005: 640x480=~0.3MP (O2 XDA Exec a.k.a Qtek 9000 , i-mate JASJAR and T-Mobile MDA IV)
2007: 480x800=~0.4MP (Toshiba Portege G900)
2010: 640x960=~0.6MP (Apple iPhone 4)
2011: 800x1280=~1MP (Galaxy Note)
2012: 1080x1920=~2MP (HTC DROID DNA)
2014: 1440x2560=~3.7MP (Oppo Find 7)

Manufacturers need to stop worrying about resolution and bragging about numbers, and focus more on color reproduction, brightness, efficiency, etc. Sony's getting it right (allegedly - we'll see) with the Z3. Bright, accurate, and efficient.

it will never stop as per me
i work as animator and if you ask me. this development of getting bigger sizes will never stop. qhd, amoled , UHD they all are the return of lakhs hour of work by the scientists. inventions are always going to come. what you asked is something like " did write brothers ever imagoned that the technology they develop that time will ever cross the speed of sound", that time it seems impossible. well here is the same concept . you don't know what will happen in future. development pace is so rapid today. nobody knows what tomorrow hold. now everything seems possible and this hunger for getting higher screen resolutions will never stop. clarity is going to clear. The human eye can see 7,000,000 colors. Some of these are eyesores. Certain colors and color relationships can be eye irritants, cause headaches, and wreak havoc with human vision. Other colors and color combinations are soothing.so its basically how far scientists can see. so this war will keep on continue forever. it will never going to stop.. the human thrust will always keep on for pushing themselves to infinity.

This so much. It extends to more than just phones. Megapixels, resolution, all that stuff. Bragging bigger numbers doesn't mean jack if the camera quality is crap and can't capture an image faithfully. Sick of seeing crap about 4k and 60fps and all that. Numbers make not a better camera.

Today's QHD is tomorrow's 360p. Resolution increments will not stop for a while.
But I agree with @Planterz, we need to focus on image and screen quality. Brightness, color reproduction, etc. are soo important. But it's hard to sell that to the general public when everyone else is selling numbers. Especially for Android where there's so much fragmentation and competition. The baseline for judging at this point is essentially specs.

The good: USD150 is a very acceptable price for Chinese phone with mainstream chipset. Mijue M10 is as fast and smooth as Cubot X6. Display is good with more details.
The bad: Though I’ve saw lower-than-mediocre back cameras like Cubot X6’s, the M10 is even worse, which, however, has a better front camera. Money on useless and crap gesture sensing should’ve been saved or used to enhance other features.
Bottom Line: Mijue M10 did not surprise me finally by functioning, but it has a right price.
The cheapest 8-core Chinese smartphone was USD40 cheaper in about 2 months, and now we see Mijue, a never-heard brand, make a debut with its M10 for USD150 or so. The M10 and Cubot X6 (USD190) share the same components except that the Mijue handset has a smaller Nand flash memory. According to a friend of mine on the sourcing market, 8Gb makes a price gap of approximately USD 5, which doubles on retail.
It seems that an overall markdown of USD30 dollars in MTK6592 mobile phones is destined for now or the few months to come. Before making that sure, we should figure out whether Mijue M10 is a normal phone or it’s priced low for reasons, because a crap, however cheap it is, is a crap.
The performance of Cubot X6 proves that the collaboration of MTK6592 Octa-core CPU plus a 4-core Mali-450 GPU well powers a 720p-display smartphone (http://forum.xda-developers.com/showthread.php?t=2647933). Huawei Honor 3X, with the similar components, is fantastically better.
And now, I’m showing you what a phone Mijue M10 is by comparison with Cubot X6 bit by bit.
1. What the hell?
The M10 is equipped with a gesture sensor, which is useless from my point of view. What’s more, it takes great efforts to keep your palm neither too close to nor too far from the screen when you make “air” gesture – I mean you have to nearly touch the screen but not really touch it.
Sometimes, people don’t appreciate the existence of something or grieve on the loss of it even if it was perfect by itself. The first rule of making a cheap phone is not to add such an embarrasing burden on it, so you can save money for something else that people really cares, for example, a good look.
Cubot X6, which costs you USD40 dollars more, has no fancy to flaunt, but is good as a common boy.
2. Design.
If someone had only half an hour to design a cellphone and no afflatus flashed through his mind, he would bring out Mijue M10. In fact, this Mijue handset is that kind of stuff you think is the copy of something at first sight even if you can’t recall which one. Just as you may guess “s/he should have committed suicidal many years ago” when the poster of Marilyn Manson leaps to your eyes, for no special reason.
However, the Chinese producer didn’t do anything stupid like leaving wide seams on the body or many physical buttons on the edge. Besides, the phone is thin and its matte-finish back cover is not cheesy, so generally it’s a neat phone without much to complain about.
Now Cubot X6 looks far more inspiring. Its copy of Arc S can be taken as a tribute to the past and the aluminum bordering the camera lens is, anyway, unique.
3. Display
To my surprise, Mijue M10 is equipped with a better display than Cubot X6 in terms of both resolution and contrast. The two phones have the same face value of 720 by 1280 pixels, but Mijue M10 delivers more details of the same picture. Have a look at the left lower part of the landscape photo. On Cubot X6, you can only tell it was a lot of grass, while on the M10, you can almost distinguish one piece from another. And of course colors are more vivid on the Mijue handset.
As for webpages, apps, or anything with white background, Mijue M10’s display is colder with a little bit sepia, which I don’t like, while you can see pure white on the X6.
4. Camera
In the same light condition, Cubot X6’s back camera takes better photos than Mijue M10 with crispier details and livelier colors, while their front cameras were quite the contrary.
5. Operating system.
The Android 4.2.2 pre-installed on Mijue M10 is the original version with everything essential such as the Play Store.
On the X6, the OS differs a little bit from the pure Android 4.2.2. Every apps icon has a background, which is lovely and helps make the interface more compact. Besides, the apps and widget sections are separate, so you don’t slide across them.
6. Performance
There is something weird about the results on benchmark apps, but I will mention it later in case it affects your judgment. First of all, have a look at the real performance of the two smartphones.
You may not observe from the video the subtle difference that I felt in reality, but switch of home screens and pictures was indeed a little smoother on Mijue M10. On the other hand, cars of NFS Most Wanted run in the same speed on both phones, sometimes a little bit faster on the X6.
From my 3-day experience, Mijue M10 and Cubot X6 belong to the same level in terms of smoothness, and they notched similar scores on GFX Bench. Though the Cubot handset is nearly 6,000 behind the M10 on Aututu, I still believe in my feelings.
The most weird is that both Antutu and GFX say the powerhouse of Mijue M10 is MT6592 which has 6 cores. I tried two sets of the model, and the results were not different. MT6592 with 6 cores! We all know MT6592 is an 8-core CPU, which is proved true on any other mobile phone. I personally can’t explain the absurdity.
7. Battery
Battery is most people’s top concern but I couldn’t give exact time of duration in my previous reviews. This time I let a 720P music video loop on the X6 and M10 when they are watched over by the Battery Monitor Widget. With the same 2,200mAh capacity, Mijue M10 and Cubot X6 lasted 4.5 and 5 hours respectively. I hope the numbers help you anticipate their durations in normal use.
Conclusion:
Anyway, Mijue M10 is the cheapest 8-core mobile phone presently, where no major drawbacks have been found during my short trial. Regardless of how they will perform in the long run, I personally think the M10 is better worth its price than Cubot X6, or any other Octa-core stuff.
History tells us that USD150 is the ultimate mainstream price for Chinese-branded smartphones with mainstream components, so we can expect quite a number of 8-core 720p-display 1GB-RAM phones with worse-than-mediocre cameras to emerge around the price before the release of the next generation of the MTK chipsets.

MEIZU MX4 hands on

I am a meizu fans, I want MX4 but can't get it now because it is stockout. I find this article from here and just share it with all people like me.

Xiaomi may be the darling of tech publications when they look to the Chinese smartphone market, but let's not forget that Meizu is the real pioneer of community-centric phone brands. As such, Meizu is sparing no effort to one-up its arch rival with its latest flagship phone, the MX4, as announced in Beijing earlier today. Thanks to the MediaTek MT6595 SoC, we're looking at an octa-core (four 2.2GHz A17 and four 1.7GHz A7) device that can connect to both FDD-LTE and TD-LTE networks right out of the box, thus beating the Xiaomi Mi 4 whose LTE variants aren't due until end of this year. More importantly, the MX4 manages to undercut the 3G-only Mi 4 by about $16 to $33 off-contract, depending on the storage capacity.
Like its predecessor, the MX4's 5.36-inch IPS screen maintains an unorthodox 5:3 aspect ratio, but with a slightly bumped-up resolution of 1,920 x 1,152. Compared to the standard 16:9 smartphones these days, the MX4 benefits from an eye-friendlier home screen as the icons are more spread out, plus the wider body can accommodate a slightly bigger pop-up video player -- a feature on Meizu's Flyme OS 4.0, which is a heavily but prettily customized Android 4.4 ROM -- when you're holding the phone in the usual portrait mode. The screen also takes up 79 percent of the phone's front side and has a narrow 2.6mm bezel, both of which look rather impressive. Meizu added that it's co-developed a screen sealant with Loctite that helps absorb shock impact, in order to reduce the chances of shattering one's screen when the MX4 hits the floor.
Despite the large screen, the MX4 is actually a phone I've enjoyed holding the most in its size category. First of all, it's only 147 grams heavy and 8.9mm thick (yet it still packs a built-in 3,100mAh battery) thanks to its aircraft-grade aluminum body -- one that claims to be harder than that of the iPhone 5s. Secondly, the MX4 carries an ergonomic curvature that's similar to that on the MX3, so there are no edges that would otherwise dig into the palm. To get to the MX4's Micro SIM slot, you can now simply peel off the flexible back cover, as opposed to using a pin to push and peel the hard cover off the MX3. The downside of that is you may feel the seam between the aluminum frame and the plastic cover, so hopefully the final production units will have a tighter fit.
Last but not least, the MX4 packs a 20.7-megapixel f/2.2 main camera and a 2-megapixel f/2.0 front-facing camera. While the latter's resolution is rather disappointing, it does offer a live beautification mode, which lets you preview the enhancements on your eyes, chin and skin before taking selfies. As for the main camera, its 1.2μm pixels will apparently handle dark environments just fine, plus its speedy image signal processor can handle 25 fps continuous shooting in 10-megapixel mode, 720p slow motion capture and even 30 fps 4K video capture. For the icing on the cake, there's a dual tone LED flash for better results when using flash.
The MX4 will be launching on September 20th globally, though only China prices are available at the moment: The 16GB model is just CN¥1,799 (about $290), whereas the 32GB flavor is CN¥1,999 (about $325), and the 64GB model costs CN¥2,399 (about $390). Pretty aggressive, right? And for the record, only the gray edition will be available to begin with, followed by a white edition and a gold edition. Much like the Smartisan T1, you can also purchase a liquid plus screen protection warranty for just CN¥89 (about $15) per year.

Display:
This handset comes with 5.5 inches IPS Full High Definition display with 401 pixel density. The display sharp and vivid, flawless touch responsive with good viewing angles. The sunlight legibility of the display is also good. This is a certainly good display to considering this price range.
Camera:
This device comes with 13 MP Primary camera with single LED flash and 5 MP front facing camera. Both cameras capable of taking impressive shots, the images taken by this phone good detailing and clarity. But in indoor/low light scenario captures images shows slightly noise however, it can capture decent images in low lighting conditions. The overall camera quality good enough to considering in this price point.
Design & Build Quality:
The Le1s sports all metal body, device feels pretty premium in hands, but also feels little bit heavy, it’s only because of its metal built body, but no problem it is not a big issue, overall it feels pretty slim. The back panel of the smartphone is non removable, means you cannot remove the battery from the device, which is a good point. The smartphone measures 151.1×74.2×7.5mm and it weighs only 169 grams, in thickness it is just 7.5mm thick. Overall the Design and Build quality is fantastic.
Hardware & Gaming Performance:
It is boosted by a 2.2Ghz Octa-Core MediaTek Helio X10(64 bit) processor, along with 3GB of RAM, and it has a PowerVR G6200 GPU for videos and gaming. The hardware specs itself explained that how much powerful the device is, so really without wasting any time let us discuss about it. Overall experience with this device is pretty good or we will say very responsive, we have done lot of multitasking and phone feels smooth. In terms of gaming we challenged the device with industry’s most powerful to most popular small games like, subway surfers etc, as we expect small games runs very smoothly in this device, also when we tested some of the best graphic intensive games, it feels smooth too, in this device we have played Asphalt 8, NOVA 3, Injustice, Six guns, they are very fluent, to be fair we haven’t noticed any lag with the device.
Verdict:
LeEco Le 1s is a well performer, it is very smooth in terms of browsing experience. The device is well performing in all most every section, like we have tested some Games and we didn’t notice any lags. The daylight performance of the camera was awesome, in other words the device feels damn premium. If you want a beast in your pocket, and want to show off within your budget, then this is for you.

18:9|18.5:9 Aspect Ratio MEGA RANT

What's the number one single most important thing about a screen's aspect ratio? IT'S COMPATIBILITY. Screen real-estate, maneuverability, SCROLLING POTENTIAL are all but NOTHING compared to compatibility. If my phone, or ANY electronic for that matter, features a screen incompatible with PRETTY MUCH EVERY OTHER VIDEO OR IMAGE on the internet and everywhere else, I WOULDN'T BUY IT. Do you know what you're doing when you buy phones with abominable aspect ratios?? You're FEEDING the corporate, capitalist minds of CEOs who think their customers are dumb enough to not notice black bars EVERYTIME they watch a video!
We need to GET REAL here: 99% (exaggeration) of ALL KNOW VIDEOS on the internet are in the 16:9 aspect ratio. Discarding old media (4:3), the rest are the professional movies recorded in 25.6:10.725 (2.39:1) and 12:5 (2.4:1 Blu-Ray crop). Now, one could argue Ultra-Wide 21:9 is acceptable due to it being very close to the cinematic standard of 2.39:1, but 18(.5):9 is NEITHER CINEMATIC NEITHER STANDARD AND NEITHER PRACTICAL!! We SHOULD NOT have to endure manufacturers being SO F'ING BRAIN-DEAD that they think our pleads to reduce bezels also mean we're willing to sacrifice a UNIVERSAL STANDARD. 25.6:10.725, 12:5, 21:9 (barely) and 16:9 are the ONLY ACCEPTABLE ASPECT RATIOS FOR A PLEASING EXPERIENCE. Why do we have to endure bezels like it's suddenly 2010 again? 18:9 WILL NOT BECOME A NEW STANDARD. It's literally a STUPID TREND, JUST LIKE REMOVING THE HEADPHONE JACK or MAKING BATTERIES IRREMOVABLE. It's gotten to the point where the Mi Mix, a revolutionary phone in terms of bezel-less design that KEPT the 16:9 ratio, was CHANGED TO 18:9 in the Mi Mix 2, JUST BECAUSE EVERYONE ELSE WAS DOING THAT. The Mi Mix screen design was awesome, and was ENOUGH. That extra 1 to 2% of extra screen estate IS NOT WORTH THE HUGE BLACK BEZELS. What's the point of reducing physical bezels, only to increase digital ones? And in the era of (thank god) OLEDs, constant unchanging parts of the screen like digital bezels are just MENTAL to put on a display that is SUSCEPTIBLE TO BURN-IN. It's just DUMB to put a 18:9 aspect ratio on a screen. Keep it 16:9 for now, until we get rollable OLED, and when that time comes, make a screen that de-rolls from a 16:9 one to a 12:5/25.6:10.725 one. Why, oh why have manufacturers done this... Finger gymnastics and incapacity of one-handed use have never been as dire a situation as it is now... Just REDUCE THE BEZELS AND KEEP THE HOLY ASPECT RATIO, DAMMIT!! Absolutely NOBODY wants to make the choice of either cropping, stretching or pillar-boxing!! It's time to STOP!! And don't get me even started on the huge notch the iPhone X has!
all other android phones got notch also, removed head phone jack, got swipe gestures. seem's like Apple is leading the way. and the android sheep follow
While black bars look as annoying as they do, this problem is only relevant if you consider photo/video viewing as a primary use case of the phone. Most phones in the last year or two are hardly advertised as mobile p/v viewers. High end OLED phones have more or less the same screen IQ (which often goes beyond what the content is made for), while decoding performance has been more than enough on a small screen for a long time. So there isn't much money to make from "my phone does YouTube better than yours".
If you're a heavy mobile p/v user, the current situation on the market sucks for you. But calling them "brain-dead" when what they do makes business seems to do little to make your life better.
I do agree with the finger gymnastics comment which should apply to the majority of users that have normal human hands.
Edit: Didn't notice this was a November 2017 post.
I hear you…
I hear you man. The new super long, super stretched or super whatever aspect ratios are STUPID :crying: DUMBASS.
I use my 16:9 smartphone a lot in landscape for browsing the internet, and at times it already annoys me the relatively reduced “height”. Some webpages even stick stupid onscreen squatter bars when in landscape, let me show you an example (I use a reduced screen dpi to maximize my screen content, 256dpi from the default 415,5dpi of my device):

Portrait mode, no bars.
Landscape, big squatter bar which cuts content.
Any time the aspect ratio is increased the screen becomes less flexible. 4:3 or even full square :fingers-crossed: owns LoL. 16:10 is great, can live with 16:9 but anything beyond that is MORONICAL. :silly:
Cheers fellows
I don't care if this thread is old. I agree completely. I'm using an 18:9 phone and I hate it. Everything is too narrow. I use my phone exclusively in landscape except when making calls. The 18:9 gives me black bars or cut off picture on everything. The length makes the keyboard near unmanageable as well. Finger gymnastics like crazy and typos everywhere! Never again. They also need to get rid of the hole punch, notch, dimple idea too. It looks terrible. Try watching full screen video on that. You'll hate life. And I don't even want to think about gaming... I refuse to buy another phone isn't 16:9, or 16:10.
Good to know...

which mobile better in reading-browsing for long time IPS or flagship amelod

i need phone not tab or iphone or ipad or kindle
for reading books - browsing some leaning app
i do not use it for gaming or camera
so MI 10 t with IPS screen as many say it is better for eyes
or go for samsung s21 Ultra
i know it is big difference in price also in spec
i can get s21 ultra
but what i want o know s IPS screen will more comfort for long reading use
or the dynamic amelod will be better
i think i read hat S21 ultra
have many certification in eye protection and have low blue light
so which better to go
I'm not an expert but I don't think one of them is specifically better for reading/browsing (although AMOLED is overall better than IPS).
If you want a device specifically for reading I'd get one with an e-ink display which is better for your eyes than either IPS or AMOLED.
Edit: I googled it to make sure I know what I'm saying and apparently there is no actual evidence e-ink is better for your eyes.
Who knew.

or go for another company
i found some review about s21 ultra take about technology to save eye
but could not find for any other company
could you google as you can find some
thanks alot
Advantages of AMOLED over LCD technology
In addition to the power-saving effect, an AMOLED display has other advantages compared to an LCD: No backlight also means less heat loss. In addition, AMOLED displays deliver significantly stronger contrast, deeper black levels, a wider color gamut and excellent viewing angle stability in comparison. In addition, AMOLED displays have up to 1,000 times faster response times than LCDs - in some cases less than a microsecond. And OLED screens allow not only flat-built but also curved smartphones with their design.
Examples:
Lefthand a device with AMOLED-display, righthand a device with IPS-LCD display

There probably won't be a Note 21, and I don't think the S22 Ultra will have a screen much better than the S21 Ultra (which is already nearly perfect).
So yeah, I'd get the S21 Ultra.
