Is PLS the tablet's AMOLED ? IPS vs PLS video

http://www.youtube.com/watch?v=2-aE6SZkdHw
Just check out the difference in color rendering and luminosity between the two.
And the quality gain gets even wider with viewing angles according to PLS technology sheets I've been reading.
This seriously makes me condiser the gtab again over the transformer now.

Well Samsung did state that PLS was the evolution of IPS. So... I'm assuming it was supposed to better from the start. I don't know if it truly is. I will be waiting for Anandtech's review to find out.

I bet Samsung is dying to put Amoled on on these new tabs, but I doubt it. I would only buy it if it was Super Amoled Plus (Pentile Matrix...), But I doubt it. Seems like it would be a little expensive. I do imagine however, that Sammy's made some sort of cheaper display that looks just as nice.

Well Samsung have shown a 7" SuperAMOLED screen intended for tablets
My guess is that the next Galaxy Tab "7" will have SuperAMOLED (hopefully plus) and it will probably have the Exynos SoC

Interesting, but I doubt the 10.1 will be SUPER AMOLED because it's only $500.

It won't. They already said it will be PLS.

Interesting... There was a notion ink adam a few inches away

The Transformer Prime will have the brightest display of any current tablet. (Maybe).

The Max brightness is 600 nits. Note: 1 nit is equal to 1 candela/m2.
As you can see on this review there is a chart showing the candela brightness of the Xoom, the iPad2, the Galaxy tab 10.1, Iconia tab and the old transformer.
http://reviews.cnet.com/tablets/samsung-galaxy-tab-10/4505-3126_7-34505347-2.html?tag=mncol;rvwBody
The brightness of the TFP is nearly double the brightness of the old one and I haven't been able to find a tablet that is brighter than any of them.
I don't know about the "30% boost in Color enhancement" but I assume it may mean saturation closer to amoled levels. This to me is a good thing even though others may disagree.
Looking very good.... VERY GOOD.

Brightness is a funny thing. I keep mine at 10% or less on all my tablets because I don't feel like staring into the sun for 10+ hours a day :-O

Samsung Galaxy NOTE 10.1 hands on

UPDATE: I had to take the videos down for the moment at Samsung's request. There is information that they are about to change some design features and specs, but I don't know when and what exactly. I'm sorry for the situation, but I assure you I'll post them back as soon as I get word of it! Thank you for your interest and patience
I've had the chance to play around with the Note 10.1, that's the tablet with the S Pen. The reason they've delayed the release is that they've changed it dramatically since the preview at the MWC. It now has a 1.4GHz quadcore processor (I think it's the Exynos on the SIII), a 5 MP camera (instead of the 3.15) and the back got a hyperglazed finish just as the SIII. I've had the pebble blue one and I'm not sure if there is a marble white one.
The S Pen is much bigger than the Note 5.3 (looks EXACTLY the same), but smaller than the model shown at the MWC and it now fits inside a vertical hole in the lower left side. An amazing software feature is the Photoshop Touch app which is brilliant (as you may see in my video).
Here are my videos:

S Pen and Photoshop Touch review: http://www.youtube.com/watch?v=J0b0SRT_D74
It's an astonishing device, clearly stepping way higher in the high end line and it works like a charm. If you have questions feel free to ask, but unfortunately I no longer have it to do extra demos.

Which is the resolution? Still stuck at that 1280x800??

Yes, but I had no problem with it. At 150 ppi it's quite ok in my opinion.

If the resolution will be the same it will not compete with the ipad and will not sell well and i will not buy it either.

Thanks for the videos! This is a first day purchase for me. Any news on the release date?

Even 1920x1080 are too low for a 10.1. To compete with ipad visual quality they can barely put this resolution into a 8.9, but for a 10.1... no way it's too low.
Omg, Samsung is fond of low ppi especially if fullRGB, yes it's cheaper to build but OMG!

Unfortunately I have no such info, but given the fact that *I* (not some hotshot official) had access to one, it can't be far.

BS.
1920x1080 is normal-sized monitor HD resolution, to say it's too low for a 10.1" screen is beyond ridiculous.
iPhone's "Retina" resolution is completely worthless on a useless 3.5", iPad's "Retina" display is overkill. The higher the resolution the better... up to a point.
Beyond that you are just paying a weight and power consumption (and also brightness in the case of the Ipad) penalty without getting your worth (the higher the resolutions the less your eye is able to see the difference).
Full HD resolution on a 10.1" would be ideal.
P.S. "Samsung is fond of low ppi"??
The Galaxy Tab 10.1's PPI is over 10% higher than the iPad2's.

Great. Thanks for the videos. I really look forward to a launch. Hopefully very soon. I aim for this to be my note-taken tool at work. I hope it will live up to that and be usefull. (Not hand click when using the pen etc.).

Normal sized monitor is not meant to be used as close as a tablet.
The closer a device is used the higher the ppi should be. For a smartphone pixels start beeing unnoticeable from 320-330ppi. Actually the best job is made by lg with 1280x720 on a 4.3" and 342ppi, higher than apple.
The tablet is meant to be used less close than a phone, so the ppi can be lower, around 250... the value adopted by apple in ipad3.
So for an optimal view the ppi has to be higher. 1280x800 on a 10.1 does mean a too low ppi (maybe not for a monitor, but surely for a tablet).
And yes, I confirm that samsung is fond of low ppi devices. You tell me the higest ppi of a fullRGB display of a Samsung device. FullRGB only, because the pentile matrix trash doesn't worth any talk, you know that at ppi being equal the visual quality of a pentile is much lower due to less subpixels, so i.e. the actual ppi of a 300ppi samoled hd is around 250, but this is something already well known.

Do you have any information about battery life?

i'm thinking about buying a tablet .. and i was comparing between this one and the galaxy tab 2 10.1 .. i'm going to buy it for college use .. to be honest .. i haven't had any tablet before .. it's my first .. and i want recommendations .. which one should i buy .. galaxy note 10.1 or tab 10.1 or go for an ipad 3 ?

The tab 2 10.1 is painfully slow. It's disappointing because it could have been a much better option if they had just put in a better processor (I know the tablet is supposed to be entry level, but the year-old exynos from the s2 would have been better). I'm not a huge gamer, but I do want a tablet that runs without much lag out of the box. I also want to play HD video files without frame skipping and the tab 2 10.1 isn't very good for this either.
As far as the other 2, it depends on you. The new ipad is nice. It's fast and has a fantastic display. My brother in law has one and absolutely loves it.
Personally, I usually gravitate towards android (and samsung). The note 10.1 doesn't have the PPI of the ipad, but it can fully display 720p hd video which is good enough for me. The screen is also a little bigger (than the ipad). Memory expansion is nice through microsd and the US version should have the IR blaster to use as a universal remote. The potential of using the s-pen for note taking and drawing is also a big plus for me. The quad core processor should also be able to handle just about whatever you throw at it (at least for a couple of years).

I wish the resolution was higher. I hate the display on my Tab 10.1, there's a distinct lack of clarity.

Probably gonna exchange my tab10.1 for the Note10.1
Hope it will launch soon, any rumours on that subject?

That ppi is still ridiculous. Either they increase it till around 250, or sammy will get only low end customers.
But since they still use that crappy ppi on high end smartphones, I guess they are not able to increase the ppi in a tablet.

How close do you hold a tablet? How far do you sit from a monitor? For me it's only a few inches difference in usage? i sit approx arms length away from my monitors and hold my tablet only a few inches closer than that (arms slightly bent)

well then the tab 2 10.1 is out of the race .. now the iPad 3 And The Note 10.1 .. so your recommendation is to have the note 10.1 right?

That's what I'm going with, but i don't think there's really a wrong choice

I'm amused by all the comments linking the tablet to the low end of the market simply due to the low ppi. Clearly, everyone has different requirements out of a device. By putting a stylus on a 10" tablet, Samsung attained my personal "Shut up and take my money!" threshold. **** PPI, do you know how incredibly, mind blowingly useful a stylus is? As soon as I can figure out where to buy this thing, I'm buying it. I've been begging for a full sized tablet with a stylus ever since the original Note came out. This is my actual dream come true.

The Screen Resolution of Tablets

With the exception of the iPad (2048*1536) and the Asus Transformer Pad Infinity (1920*1200) most tablets including the 7.7 have a screen resolution of (1200*800).
The same screen resolution (1200*800) is available on the galaxy Note with a 5.3 inch screen. So a 7 inch screen such as the 7.7 would need a resolution of (1750*1160) to equal the Note. and a 10.1 screen would need a resolution of (2286*1524).
When I decide to buy a 7 inch tablet then I would want the screen resolution to be at least as good as the Note. How long do you think it will be before the next 7.7 has improved screen resolution to match the Note?

The Note is actually 1280x720,a small difference true. Edit: shouldn't trust my friend even though he owns a note... It is 800
But the bigger difference is that the Notes screen is Pentile and the 7.7 is not. Using Pentile to get higher pixel density just feels like cheating to me. Higher pixel density is supposed to make things more crisp, but a Pentile matrix does the opposite.
And the other two you mentioned aren't amoled, so they can't really be compared either.

I cannot give you a technical answer but I own both the note and the 7.7. The resolution on the tab is just superior. Put the two next to each other in a shop and you will see the difference instantly.

Hi Gaugerer, 7.7 actually has resolutions of 1280x800 instead of 1200x800.
Also, I agree with kishd. Put a Note and 7.7 side by side you can see clearly that the pixels in 7.7 are arranged in perfect grid, while the pixels in Note are arranged in pentile matrix, as in SIII.

The Note is not 1280x720. It's 1280x800; just like the Tab 7.7. I have both.

Thanks for your replies and for correcting my Note screen resolution. It seems that most of you are happy with current resolutions on Android tablets, but I wish we had iPad3 dpi for it would help with my charting and multiple windows.

Of course the more the better XD
We are hardly some fanboys who would defend its short-coming
Having said that, resolution is not everything. You would like to look at contrast and refresh rate, as well as how pixels are arranged. The overall watching experience depends on these as well.
But if you don't want to digest too much technical detail, just go to shop and try it out on your own

Galaxy S4 mini

Samsung annonced officially, the Samsung Galaxy S4 mini.
it has 4.3" qHD disply, android 4.2.2 but with out most of the features of S4 (like no double shot, no 360 panorama), has S Health but with out S4 sensors like temperature sensor, barometer and humidity sensor
chipset is most likely Snapdragon 400 at 1.7Ghz with 1.5Gb of RAM and internal storage is 8Gb with Micro SD card slot for expanding it.
rest of connectivity options and usual, wifi, bluetooth,GPS with GLONASS etc...
also has IR blaster for remote controlling.
the phone has dimensions of 124.6 x 61.3 x 8.94mm and weighs 107g which is cool
battery is user replacable and is 1900mAh.
no word on pricing. samsung will show it off on June 20 and most likely to reveal pricing then.
available color options are Black Mist and White Frost.
i kinda like it except the qHD screen. it should have been at least 720p but all its success depends on its pricing.
what do u guys think?

The SIII Mini always struck me as a bit pointless, having neither the spec to appeal to those that like phones with a bit of muscle or the price point for those that want a decent phone on a budget. It didn't really satisfy anyone and I have a sneaky feeling we're going to see more of the same with this.

Definitely not more of the same, but then the s3 mini was especially useless. Rumors/leaks have the ATT version of the s4 mini at 720p (presumably pentile, but no confirmation). But gsmarena just confirmed that the version announced for europe is NOT pentile. It's got the same RGB s stripe as the Note 2. At 4.25" with qHD, it has a very respectable 259ppi that is at least as sharp as a Galaxy S3, and maybe slightly sharper. I'd almost as soon have RGB qHD as 720p pentile, so at least I know for sure what I'm getting. It comes with air view and multiwindow, which is kinda surprising.

I saw it in a video (closely), and it's not as sharp as S3.
I don't know but it's clueless to compare the number of subpixels to say which is sharper.
With the lower ppi, Note 2 is still a little bit sharper than S3 because they scale it the same as S3 (by adjusting ppi) and no pentile effect on Note 2. But they cannot do the same on a smaller screen like S4 mini-

It's clueless to think you can make a screen sharper through scaling (presumably, you meant adjusting "dpi"). And to claim subpixels have nothing to do with sharpness but still hail the Note 2's lack of a pentile effect as responsible for it's sharpness. What do you think the pentile effect is? And to think you can divine screen sharpness through an encoded web video. Trust me, you can't.
You can pixelate software elements through improper scaling, but you can't sharpen a low density screen through software scaling. For example if you zoom in enough (a form of 'scaling') on a small image even viewing it on a super sharp screen, yeah, it'll look bad, but that's not the screen's problem. If you've got a low density screen, the sharpest of images will look crappy no matter how you scale them. The S4 mini is sharp for the same reason the Note 2 looks sharp: because they share the same complete RGB matrix and almost the same density.
Pentile is nothing more or less than false advertising, a way of artificially inflating the raw spec. It's not the worst thing in the world, it just requires a much higher purported ppi to reach the same sharpness as an RGB matrix screen.

Again like the S3 mini, Samsung is trying to milk more money out of the S4 series but now targeting the mid-range side. Average consumers will probably buy this as there is an "S4" tag on it and is much cheaper than it's big brother.

I don't think you understand my opinion, maybe due to my bad English. To say clearer, what I mean is the Note 2's screen's scale is basically the same as Galaxy S3 with the same 320 dpi - zooming from 4.8 to 5.55 inch. This means, a same font of texts, a word with a length of 120 pixels on S3 (1/6 of the total length) is still 120 pixels on Note 2 (also 1/6 of the total length), but 15.625% bigger in real-size (what you actually see). So is the result is what you can see clear on S3, you can see it CLEARER on Note 2. That's is the technichque Samsung usually implements, like on Note 8.0 that make it much more sharper than iPad mini in browsing. If we compare a same line of texts with 5mm of "real size", the result from a screen like One X basically has 18% more pixels to illustrate the detail of the text, which results in being clearer than Note 2. And if you really have a Note 2 (i'm using it), when visiting some websites in desktop mode (like xda forum, lol), the text is very small and not crisp anymore.
But how about Galaxy S4 Mini? "The S4 mini is sharp for the same reason the Note 2 looks sharp"? OK, now we will consider the same thing as Note 2 above. For a line of texts equivalent to 1/6 total length of the screen, it takes only 93.33 pixels, which means noticeably less than S3 and Note 2 with smaller "real size" also, so it cannot be as sharp as S3. And in fact, Samsung did rescale from 320dpi to 240 dpi on Galaxy S4 Mini, which also means for a same font of texts, the number of pixels for displaying increases about 15.3%, so from 93.33 pixels I said above now it is appox. 108 pixels, which is not too far from Galaxy S3, and the payoff is the screen is cramped. So we cannot say "because Note 2 is sharp so Galaxy S4 Mini is also sharp"
About Pentile screen, it is not totally "nothing more or less than false advertising", but more like "false understanding of the major and the misleading criticisms". Why? Because most of people don't understand what is "Pentile". In fact, this "technology" can ONLY be used on OLED (AMOLED) technogy, which has the uneven luminance and lumious time of different color subpixels. Even experts cannot show the "exactly" ppi of an Pentile Amoled screen (because even with Pentile, different stripes layout leads to different result), while some people try to do an easier way that comparing the total number of subpixels, which is totally false. In fact, Galaxy S4 has 623 subpixels/inch, slightly higher than Blackberry Z10 (615) and iPhone 5 (565), but it is MUCH more sharper and not really different from the normal RGB 1080p screen like Xperia Z.
With Pentile screen, the main culprit of all criticism is not the lack of subpixels, but the uneven scale of pixels (because they're not real pixels) and uneven big-small gaps redundant. That's why they call the subpixels layout of S4 is innovative while still Pentile, because it is much much better than the traditional matrix on Galaxy S3 and together with the high ppi reduces most of Pentile problem (in fact, with traditional matrix, even with 441 ppi probably there will be something there)

No info. There isn't a root for the 9190 yet - the 9192 and 9195 procedures do not work on the 9190 and will probably brick your device.

hello, does anyone know when this phone will be available in the usa? can not find any info on this
if this is in the wrong forum please move, thanks

Which phone should i buy? sIII or s4 mini

Hmm, you've mentioned the main benefit of getting the S3 I guess.
Also, the S3 has quad-core as opposed to the dual-core S4 mini. S3 has 1 GB of ram only though.
There are also more accessories for the S3 than for the S4 mini because the mini has a smaller market and is also a newer device.
