A bit of lag.. - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Is it just me or does this lag a little.?!
Don't get me wrong i love it, it's just i have a nexus 5 with the snapdragon 800 in it and it's perfectly smooth.
It's quick.. but not as good, particularly in web browsing zooming and scrolling. (sometimes you touch things when you dont mean too, sometimes it's slow to pinch zoom,maybe this is the touch screen issue not shaw.. )
Hopefully it's just software and sony will get it better. With this hardware it should be perfect!

Have you upgraded the firmware to the latest available ? Some people reported occasional lags that went away after upgrading.

yes I'm on 402..but my nexus 5 is smoother and it shouldn't be..anyway I'm still happy..

The touch screen does have a grounding issue, of which the severity seems to differ per device. Maybe that's what you are experiencing.

A 10.1 inch tablet which has the same specifications and is exactly as fast as a 5 inch smartphone will ALWAYS seem more laggy!
This is just because lags which are very small on the phone (bordering on un-perceivable) are magnified on the tablet and thus seem more severe!
But in reality it's just a matter of scale, an optical "illusion".

the nexus 5 has resolution 1080 x1920 and a slower cpu snapdragon 800...
i think maybe it is a touch screen issue, it's a bit random.
I'm sure sony will get it better..

Nexus has same resolution. Nexus is a pure android software with minimal background processes. Sony has customized their own ui with extra and not as optimized background processes. There is also the scale thing, where as u won't notice lag on small screen as much as big screen.
Ur welcome

Yes, right.
Coreo, you can use alternative launcher instead of the Sony one; you can root the device and disable/uninstall the Sony bloatware/unnecessary background processes.

The Z2 tablet actually has a marginally higher resolution of 1920x1200 pixels.

fair enough... but it still feels smoother and quicker.. yes I've rooted, deleted a few sony apps, replaced the keyboard with swift keyboard and installed nova launcher..
PS im not complaining, it's still fast and am very happy with it. im just comparing it against the snap dragon 800, as a fair or unfair comparison it may or may not be..
in someways its a good thing as sony have room to improve..

New high resolution Prime perfomance (the Google+ article by Dianne Hackborn)

Hi all,
I know this article has been floating around here for some time, but this I found rather interesting:
Some have raised points along the lines of Samsung Galaxy S2 phones already having a smoother UI and indicating that they are doing something different vs. the Galaxy Nexus. When comparing individual devices though you really need to look at all of the factors. For example, the S2's screen is 480x800 vs. the Galaxy Nexus at 720x1280. If the Nexus S could already do 60fps for simple UIs on its 480x800, the CPU in the S2's is even better off.
The real important difference between these two screens is just that the Galaxy Nexus has 2.4x as many pixels that need to be drawn as the S2. This means that to achieve the same efficiency at drawing the screen, you need a CPU that can run a single core at 2.4x the speed (and rendering a UI for a single app is essentially not parallelizable, so multiple cores isn't going to save you).
This is where hardware accelerated rendering really becomes important: as the number of pixels goes up, GPUs can generally scale much better to handle them, since they are more specialized at their task. In fact this was the primary incentive for implementing hardware accelerated drawing in Android -- at 720x1280 we are well beyond the point where current ARM CPUs can provide 60fps. (And this is a reason to be careful about making comparisons between the Galaxy Nexus and other devices like the S2 -- if you are running third party apps, there is a good chance today that the app is not enabling hardware acceleration, so your comparison is doing CPU rendering on the Galaxy Nexus which means you almost certainly aren't going to get 60fps out of it, because it needs to hit 2.4x as many pixels as the S2 does.)
To be complete, there is another big advantage that the GPU gives you -- many more drawing effects become feasible. For example, if you are drawing a bitmap in software, you basically can't do anything to it except apply an offset. Just trying to scale it is going to make rendering significantly slower. On a GPU, applying transformations well beyond simple scales is basically free. This is why in the new default Holo themes in Android we have background images -- with hardware accelerated drawing, we can afford to draw (and scale) them. In fact, if the hardware path is not enabled by the app, these background images will be turned off.

This is kinda the same as with the Prime and the T700/other high-resolution tablets, isn't it? I'm not sure, but it sounds pretty obviously since the Tegra3 GPU isn't very good (yes, it is fine but I'm not sure for those high-res screens?). However I could be completely wrong..
I agree. It's the same with a gaming computer. Just because ur monitor has 1080p doesn't mean u can play all games in that rez. U will need a much more powerful gpu. I am certain though the tegra3 can support 1080p but it won't be smooth as 720p like our device. Unless u lower the rez but how would u on an android. Furthermore how ugly games would look who aren't optimize for 1080p.
Nvidia always!
The question isn't whether there's going to be a performance hit, it's what the performance hit looks like. If it's invisible in everything but gaming, I'd bet a lot of people will go for the HD display and gamers will stick to the lower res. If it's obvious in UI performance and transitions, it makes the benefit of the HD screen a little more questionable. The new chip in the iPad3 and Samsung's new Exynos chip won't make you choose (on paper). Benchmarks are useless except for bragging rights.
I have been saying this since people were trying to compare the new acer and samsung back in Dec. The higher the resolution, the more power and resources it takes. Also you have to look at the app market right now. What app's are out that will use that 1080p display...NONE as of now. Once they (1080p tablets) are released, it will be a few months before most apps will adapt to the new higher displays.
I continue to question the need for having a 1080p 10 inch display- there has to be a limit as to high a ppi count the human eye can reasonably distinguish. Just bumping up the resolution while not working on improving the true render process (in case of games or animations) does not make any sense to me.
A retina display just for the heck of it is not a great idea, at least to me.
For what it's worth, ICS is supposed to be fully hardware accelerated, so the Tegra 3 could be enough to power the higher resolution for everything but games.
Anandtech (who I probably trust the most when it comes to hardware evaluations) seemed to suggest in an early preview that the higher resolution *may* perform ok:
http://www.anandtech.com/show/5348/...-with-asus-1920-x-1200-tablet-running-ics-403
That said, there are still questions as to the benefit of such a high resolution on a 10" form factor designed to be held only 1-2' away from your face. They didn't bump up to 1920 x 1200 resolution monitors until 24" LCDs and up.
The real issue is that games on Android don't let you pick a resolution for them to run at. Almost all run at the full Res of the screen, which means slideshow on a 1080p Prime.

I agree, there is just no point..... there is more important things to improve than pixel count....
Thanks, at least I am not alone on this idea. It seems like when the news came that the iPad 3 is going to have a retina desiplay all the manufacturers didn't care anymore and just were thinking "We also need that!". I am comparision the text from thread with my HTC Sensation which should have a better DPI:
Transformer Prime: 149
The new Prime: 218
HTC Sensation: 260
and from NORMAL viewing distance both look great. However, when i come closer the pixels on the Transformer Prime are a little visible where the Sensation stays sharp. However the phone has a better DPI then the new res. panel so I'm not sure how that is.
I'm sure it will look some better, but I am not sure if it is worth the wait (again) and also the possibilty of the new Prime itself can't keep up with its own resolution..
Oh, again not trying to defend the Prime here.. I have to return it anyway because of backlight bleeding and am not sure if I want a new one or my money back, however if I see this result I think the resolution is just pure marketing.. I mean who is going to sit with its prime 5 cm from their heads.. lol.
http://androidandme.com/2012/01/news/hands-on-with-the-acer-iconia-tab-a510-and-zte-7-tablets/
Watch the video on Acer Iconia a510 (unannounced tablet). 1080p that comes with this tablet... does look a bit sluggish.
Just to add my galaxy nexus is 316 dpi..... unless your 2in from the screen...there really isn't much difference.
Also, I love how laptop and desktop DPI is half what most phone/tabs are and people are having a fit......
http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density#ASUS
Seems to run pretty good since it is still a pre-production model, however not as smooth as the Prime with ICS yes..

Yeah, exactly what I mean.. you can see it if your very close to the screen, but why would you do that, lol.
Oh, btw.. for the iPad 1&2 it still is 132, which is much lower then our Transformers (149,5), never heard real complaints about that.
>What app's are out that will use that 1080p display...NONE as of now
eBooks & PDFs. Sharper texts. More texts. One can conceivably view 2 pages side-by-side (16:10 / 2 = 8:10, or close to the 8.5:11 printed page).
With display mirroring, you get 1:1 pixel ratio when plugged into a HDTV via HDMI. This makes above use-case (high-density text consumption) much more feasible. Ditto for remote access.
Gaming perf will take a hit. Then again, gaming isn't exactly an Android forte right now, or for mobiles in general. The bulk of games are casual stuff, geared for handset resolution.
One can argue that hardcore Android gaming will prosper over time, and FPS perf will matter more. There are problems with this line of thought. First, is simply the assumption that Android will prosper on tablets, which given current sales is hardly a forgone conclusion. Second, are the fast advances in hardware and their correspondingly short lifespan. GPU-wise, the Teg3 isn't the fastest even now. By the time we get to see enough hardcore games, we'd be on Teg 5 or 6, or their equivalent. Teg3 will be old news.
But sure, if shooters and frame count are your thing, then 720p sounds like a plan, at least for the Teg3.
>I continue to question the need for having a 1080p 10 inch display
Some don't see the need for GPS in tabs either. Some don't use the cams. Different people have different uses. You shouldn't generalize your use to be everyone else's.
Rest assured that when it comes to marketing, toys with lo-res display will be viewed as inferior. Bigger is better. It's the same thing with quadcore vs dualcore vs single-core. Do you actually need a quadcore?
>there has to be a limit as to high a ppi count the human eye can reasonably distinguish
This argument has been bouncing around ever since Apple's Retina Display. Per this PPI calculator, 1920x1200 is 224ppi on a 10.1". Reportedly, people can discern 300ppi at 12" distance, given 20/20 vision. The real test is simpler and much less theoretical: walk into a store and compare the TF201 and TF700 side-by-side, and see if you can discern the difference.
>Anandtech (who I probably trust the most when it comes to hardware evaluations) seemed to suggest in an early preview that the higher resolution *may* perform ok:
Anandtech is good for chip-level analysis. For (mobile) system hardware and use-case analysis, he's just as green as many other tech blogs. Note the gaffs on the Prime testing wrt GPS and BT/wifi coexistence. I do see signs of improvement, however. They came out with a new Mobile Benchmark suite, whatever that means.
>The real issue is that games on Android don't let you pick a resolution for them to run at.
The real issue is that Android is still a nascent OS for tablets. HC was a beta which never took off. ICS was just released. The bulk of Android apps & games are still for handsets.
I have been concerned about this as well. Tegra 3's GPU is fine enough for a 1200x800 tablet, but it's going to be stretched at 1080p (this is nearly the resolution that my desktop runs at!).
I'd love a higher-resolution display, but it's a luxury (well, a tablet itself kinda is already, but even more so). It's not as if 1280x800 is cramped and blocky. I'm happy to wait a bit longer for 1080p tablets to mature and come down in price.
(I'd rather have 2GB RAM, actually.)
Well, perhaps this new release will coincide with a bump in the specs of Tegra 3. By the time the new tablet comes out, I would assume that's been almost half a year.... That's usually about the time span that nvidia would come out with a refresh of a chip design (well, they do this with their desktop GPUs, so not a great comparison, but it's possible?). So in the end perhaps the question of performance will be moot because there will be a faster Tegra 3 and more RAM in the new higher resolution tablets.
Just a thought.
Don't underestimate.
Let's wait a review or test.
Probably the Tegra 3 is more than capable of handling this kind of resolution in terms of playing HD movie, high profile compression, etc.
I saw several tests on current prime, and it has no problem with HD videos.
My only concern is battery life ... that's all.
I expect the 1920x1200 will result worse battery life, unless ASUS pump up the battery capacity or any other improvement.

Asus has already stated that battery life will be pretty much the same as the current Prime...So that should equal shorter battery life.I'll stick with my Prime for now.No Need in buying another tablet right now IMO.I'm waiting to see what Samsung brings to the table.

I don't think they can bump the specs within the generation of a chip. The only thing that can happen till then is that Asus finds an economical way to add 2GB memory to the device, Nvidia improves the production capabilities of Tegra 3 and we get a better yield of the chips. The spec increase can only happen from one generation to the next.
I think the performance will be fine. Even the battery life.
Most of the battery usage screen-wise is from the backlight, which will be the same.
Also, not much more power may be used necessarily either, especially if it doesn't end up taxing the Tegra 3 as much as we think it will. As far as we know, our 1200x800 displays may not even be taxing the Tegra 3 that much. If anything, the article shows that the Tegra 3 may be more qualified to handle that high a resolution with little to no performance degradation. There are demos on youtube of a tegra 3 device playing 1440p movies just fine, all while driving a second screen at the same time.
Of course I too don't feel the need for something that high of a resolution on a 10 inch screen, but I'll never really know until I see one in person.

is The resolution of the nexus 10 a bit superfluous

Wouldn't it be better to just have 1920x1200, I think pushing that many pixels put a burden on the battery and cpu for little advantage, With the battery size the nexus have it would have lasted as long as the ipad. I haven't received mine but I don't think it will make much of a difference compared to a full hd display. Correct me if I'm wrong.
Have you seen it in person ? Its gorgeous . Seriously. . I fell in love with the display . And performance is excellent

I think it's great.
But don't we have like 20 threads for this topic already...
It's an A15. I mean A9 quadcore and duo core krait pushes 1920X1200 just fine, so you might as well if the chip supports it. Otherwise the A15 is superfluous. I rather the screen be superfluous rather than the CPU/GPU.
You can never have too many pixels, the reason it might look superfluous is because it's so crystal clear, but try reading xda in your browser in overview mode and the tiny text is still crystal, then try it on an mdpi tablet or similar.
I'm just trying my best right now with experimentation to git pixel perfect wallpapers.

Of course compared to a mdpi the difference is huge but compared to a full hd display I don't think you will notice any difference, even in portrait mode.

I noticed the difference between the ipad 3 and the infinty/Acer. The Acer one actually has a nicer screen than the infinity btw which was surprsing. The Acer one had a super nice screen,
If there was a common resolution between 1920x1200 and 2560x1600 then I would say yes 2560x1600 is a bit overkill. However, there isn't a common resolution in use between the two and having owned a 1920x1200 tablet I can say that there is a noticeable difference between it and the iPad retina display in terms of text clarity.
All that said, I've not seen the Nexus 10 struggle to push 2560x1600. The only real issue it has with smoothness is with Chrome and this is a widespread issue. Chrome hasn't been updated since version 18 which was released back in March. Since then the Chrome for Android team has been working to get the Android port open sourced and upstream. There are already several bug fixes for responsiveness in Chrome 23+ but we'll have to wait until they make an Android release.
it's lame that you made this thread while you haven't received it...
I have gotten mine.. and have played with it for about 4 hours now.. and have lost about 10% battery.... 9000MAH is ALOT.. hasn't been a issue here..
I'd say that if your main use of a tablet involves text (as does mine, between ebook reading, browsing, RSS reading, etc.), then you simply can't have enough pixels. Other things matter, like color gamut and contrast and reflectivity and such (which is why the iPad 3 screen is so excellent even beyond the resolution), but for reading, I'll take every pixel I can get.
If you're mainly looking to game and watch video and such, then any true HD screen would likely be sufficient (and the higher the pixel count, the worse for gaming). So, pick your poison, I suppose.

How is the screen?

I'm interested in purchasing one, but for $500 and midrange specs it really needs to deliver on the screen for me. How is it? Im not so much concerned with resolution as much as precise color calibration thats not washed out or too warm/cold.
how does it look for you guys?

Well, this is not a midrange tablet, is a high end, don't get confused because is using the Snapdragon S4 Pro instead of the S600, there are not tablets that perform better than this one, also 2GB RAM, 1200p resolution (1920x1200), NFC, IR Port, Bluetooth 4.0, Dual Band WIFI a/b/g/n, microsd card slot upto 64GB. Check this review for more details about performance.
Also the screen is pretty good, has good viewing angles, great brightness, and pictures/videos looks awesome, the touch panel is very sensitive.
I'll see about getting some data when I get mine (should be Monday.) I don't have the fanciest calibration tools but good enough for the basics we're taking about here. I also have a calibrated desktop setup as well as a pile of other tablets and phones to compare to for subjective analysis.
This is not a midrange tablet. This is top of market right now.
I payed 700 for it. Plus another 150 on my country's customs. And it really really worth it.
When you have it on your hands, is just perfect!

sorry guys, i don't mean to offend but when I say midrange i mean:
- the resolution is still 1200p vs 1600p on the nexus 10
- the s4 chip, as great as it is, is devoured by the exynos 5250 in benchmarks which is in the nexus 10 (http://www.androidauthority.com/exynos-5-dual-benchmarks-125134/ reference)
when you're talking purely features (waterproof, lightest 10" tablet on the market, solid build, ir port, nfc, sd card slot, sim card lot) yes, you're right its top of the line. but as far as hardware specs go, to put it in perspective the next nexus 7 will either have an s4 pro or a 600 with the same resolution and cost roughly $300 less.
why does hardware matter? aren't those just numbers we geek over? well, often times manufacturers will push higher resolution screens on soc's that just aren't up to the task for it.
Like I said, I don't mind paying for the premium as I dont care about the resolution but I'm just concerned about the color accuracy. do the colors look washed out? is it like the nexus 7 and the nexus 10 which both have ips and (i forget samsung's proprietary panel used for the n10, which is supposively better then IPS), but in the end doesnt really matter because both screens are so horribly calibrated that its wasted?
the thing I'm actually pretty stoked about with this tablet running the S4 is that franco and paranoid android were able to create a nexus 4 color calibration kernel which works miracles for that screen. Coincidentally, thats the same chip used on the Z. I'm not sure how much support this tablet will have, but if Franco takes interest, the Xperia Z's screen will look spectacular after a color tweak...
I really hope the whites on mine aren't too warm. I would hate to turn this thing on and see it with that layer of pee-yellow on top that my 1st gen iPad and Galaxy Nexus suffered from.
As you said n10 screen got its own issues. There is question if there is need for such ppi in large devices we don't tend to hold close to face. And i wonder if future devices will chase after resolution knowing the price (atm there are only 3 android 10" tablets with HD+ screens. Color wise its very nice, warmer but not oversaturated like Samsung. However to know how it does compared to others we need to wait for RGB replication test.
In terms of speed XTZ is ahead of N10 in cpu (except single thread apps) raw power. N10 does better in browser test due to google optimalisation (in chrome or 4.2 i don't know). Mali is stronger raw what off-screen tests show. However on-screen n10 extreeme resolution works against it puting it behind http://www.gsmarena.com/sony_xperia_tablet_z-review-931p5.php .
So atm its high end, it wont be when tegra4 an s800 hit market.

A few things:
1. The S4 chip in the XTZ is actually more powerful than the Exynos 5250 Dual in the Nexus 10. The S4 in the link you used is a dual core MSM8960. The S4 chip in the XTZ is a quad core APQ8064. Coupled with the higher res of the Nexus 10, the performance of the Nexus 10 would be behind the XTZ.
2. This is a 10" tablet. Comparing it to the much faster paced 7" tablet market wouldn't make much sense, furthermore normally people get 10" tablets for different reasons than getting 7" tablets. While this is of course debatable, it would be more accurate to compare to up-and-coming 10" tablets like the new Tegra 4 tablets, which aren't slated to be released until Q3 2013 at least.
3. Screen-wise, I can't really comment since I don't have the XTZ yet (getting one on Thursday once it is released in my country). According to the reviews I read though, the colours are nice and sharp, and the screen has quite good viewing angles due to the gapless technology used in the screen. Quoted from androidpolice (http://www.androidpolice.com/2013/05/31/sony-xperia-tablet-z-review-a-surprisingly-good-tablet/):
The front of the Xperia Tablet Z is dominated by a 10.1-inch 1920x1200 LED-backlit LCD “Bravia Reality Display.” The Bravia-branded stuff is a post-processing engine for video and images, but the difference is extremely subtle. That’s not the important aspect of this panel anyway – more relevant is how it looks. In a word: good.
If I hold the Tablet Z uncomfortably close to my face, I can definitely see the pixels, but that doesn’t matter – you’ll never use a tablet like that. At a normal viewing distance – say 18-inches – the screen looks crisp and clear. Text is extremely readable and the pixels melt into lovely, fluid images. Because this is a gapless display, the viewing angles are much better than its smartphone counterpart.
The black levels are good on this device – better than the Nexus 7, for example. Below roughly 50% brightness, the blacks stay inky, but past that it starts getting a bit gray. It’s a far cry from AMOLED blacks, but it is above average when compared to other LCD panels (at least in my estimation).
We fetishize pixel density maybe a little too much. Having a higher resolution is great, but not at the expense of performance. This screen gets the job done, and does it well. You don’t need to stress about the raw resolution numbers being lower on the Tablet Z than the Nexus 10.

4. It is possible Sony may include the white balance setting in Settings just like the Xperia Z. Other devs may of course implement this feature as well.
I saw one on display in a shop. The screen is very impressive, best android tablet screen I've seen so far. Not seen the Nexus 10 screen, but I've read enough about it's light bleed issues.

I'd say the screen is quite similar to the nexus 7. Its not as good as the TF700 but its perfectly satisfactory.

A few things:
1. The S4 chip in the XTZ is actually more powerful than the Exynos 5250 Dual in the Nexus 10. The S4 in the link you used is a dual core MSM8960. The S4 chip in the XTZ is a quad core APQ8064. Coupled with the higher res of the Nexus 10, the performance of the Nexus 10 would be behind the XTZ.
2. This is a 10" tablet. Comparing it to the much faster paced 7" tablet market wouldn't make much sense, furthermore normally people get 10" tablets for different reasons than getting 7" tablets. While this is of course debatable, it would be more accurate to compare to up-and-coming 10" tablets like the new Tegra 4 tablets, which aren't slated to be released until Q3 2013 at least.
3. Screen-wise, I can't really comment since I don't have the XTZ yet (getting one on Thursday once it is released in my country). According to the reviews I read though, the colours are nice and sharp, and the screen has quite good viewing angles due to the gapless technology used in the screen.

Thanks for this, you bring up some excellent points. I'm going to take a wait-and-see approach to see if Franco or Faux will take any interest in this tablet and develop a kernel for it. Unfortunately, for that to happen I think the community is going to have to pool together some cash, like they did for the Oppo Find5...

1. I had believed in benchmarks before I used the N10 (and some chance with N7 also), Antutu and especially Quadrant are garbage. However, I still believe in the traditional benchmarks like Geekbench, Sunspider or BrowserMark (I don't use chrome, intead Ocean Browser and Dolphin which is not Google optimization and the browser benchmarks are superior). My friend bought the Tablet Z and it is somehow laggier than N10 and N7. I know we can blame the UI for it, but even it lauching apps, N7 and N10 are blazing fast.
In the real world performance, N10 (throttling fixed) > Tablet Z
3. Yes it's nice and sharp indeed, much better than XZ smartphone. The viewing angle is very good but still slightly worse than iPad 4 or N10. Texts are crisp, not as sharp as iPad 4 and N10 when comparing besides but it's satisfying when used stand alone.
Some extra opinions:
- In my country, 16GB 3G Tablet Z costs about $950 (with some stuff like external speakers and headphones which equivalent to ~$150), while 16GB N10 (shipped from other countries) costs $460
- The audio from speaker on Xperia Z is bad for a tablet, considering Youtube, movies are used frequently on tablets. The two front facing stereo speakers of N10 are not as good and Note 10.1 but still very inspiring.
- The lightweight is extremely lovable on Tablet Z. I felt a little bit hard when coming black to my not very heavy N10.
The screen is great. I was a little bit worried about it not being as high ppi as iPad/etc. I ordered it without seeing it.
I am completely happy with the screen. Colors, viewing angles are all very good. I even turned off the mobile Bravia engine.
If you are worried about the ppi/color anything, don't be. Screen is great.

For me, I don't really look at benchmarks. They're after all synthetic. Even browser benchmarks are affected far more by the Javascript engine behind it than the hardware. Chrome runs terribly in Sunspider and the like, while the stock browser with the Nexus 10 runs very fast, benchmark-wise. However I would much rather use Chrome than the stock browser app any day because of its usability
As for UI, I'm going to take the Tablet Z for a spin before I get it, see how fluid (or not) it is. I'm most probably getting it unless there are showstopper bugs - Nexus 10 is not available in my country, and the Exynos 5 Dual is simply not powerful enough to power the screen imo.
I'll post a review of it if (once) I get it. Going to touch on some of the concerns I see here I'll probably draw some comparisons to the other tablets I've used as well (Asus TF201, Nexus 7, Xperia Tablet S). Granted, they're previous gen but they provide a point of comparison

I did the same thing and I'm a little worried. June 6th release, this comment is making me more at ease though.

I'm in the same boat. Nexus 10 16GB costs more than the latest 16GB iPad. After being blown away by everything about the tablet and how much better it is, imo, than the Nexus 10, it was a no brainer since it's the same price as the 16GB iPad. Plus I picked up a 64GB SD card and the total cost is still lower than a 32GB iPad... and I get a 80GB tablet instead. Can not wait for this to arrive.

I'm hoping the same. Franco's gamma and color tool did wonders for what I felt was a very washed out screen on the n4.
I think the screen on the xtz is pretty good but a little too warm. I'd pay good money for a screen calibration tool.

violet grays
I've seen 3 Tablet Z in a shop in Moscow, and the screen was the only issue which stopped me from buying one. The whites where slightly yellowish which I could get used to, but the grays were of purple tint!
I even made a side-by-side screen comparison between Sony Experia Tablet Z, Samsung Galaxy Note 10.1 and iPad 4. I opened the same web page on every device and compared the colors as well as the text quality.
Samsung has a cooler white point, which means the whites were slightly bluish, the grays were also a little bit cool but ok. The text quality has been foreseeably lower than on other devices since Note 10.1 has lower resolution.
iPad is the best in terms of readability and color accuracy - white is quite neutral, gray is gray. The text is rendered very clean.
Sony Experia Tablet Z's white was noticeably more of yellow tint and the shades of gray were all slightly violet. In general, it looked like washed-out old picture. The text was crisp but I'd say has been not so comfortable for my eyes as on the iPad.
Moreover, one of 3 Sonys had more of violet hue than the other two! The salesperson whom I showed this difference told me it was a preproduction item just for demonstration, and the other two were for sale. Which also shows that the tablet really has this issue.
That was a big disappointment for me which prevented me from byuying the Tablet Z. I wish I know if there is a way to calibrate the tablet's screen.
the screen is stunning anyone who says other wise is being very petty. colours great sharp and very vibrant

Colours are great, sharp and very vibrant indeed.
But still there are problems I described above.

My Thoughts of the Galaxy Alpha

I'm just writing this to share my experience of the Galaxy alpha, I'll keep updating this as I think of more stuff to write. I'll also post pics when I can
But first I got to say this is an amazing phone, especially at the price I got it for, $270 new for the 850A,
I'm most impressed with the battery life, I average about 3 hours and 30 minutes of screen on time, and that's over 12 hours, right now it's at 11 hours with 1 hour and 30 minutes of SOT, with 53% left, If I push it I can get 4 hours SOT
Also I'm also surprised with the display, I came from a G3 with a 2K display, and before that an HTC One, you do notice the pixels about 6 inches from your face, and you shouldn't have it that close anyway, at about foot away it looks as sharp as my mom's G2
I'm not terribly impressed with the camera
Its takes very good photos outside, better then the G2, but in low light it's probably the worst I've ever seen
But one positive is the camera lens, it's very scratch proof, my mom and I got our phones at the same time, and used them the same, hers is full of scratches (my G3 was the same) and mine has not one speck
That's what I'm going to write so far, let me know if you have questions, I'll keep updating this thread with pics and more stuff I find to write about,
I also came from the G2 and I think the upgrade to Alpha is really good.
The best thing about the Alpha is its responsiveness (especially in lollipop) is the closest to an iPhone i've seen from an android device. It also kills the g2 in gaming---try running GTA San Andreas on G2, its hardly playable.
FOr the screen, I love the AMOLED Contrast but the resolution is horrendous due to the pentile display halving the already little 720p resolution. I really hope they atleast made it 1080p.
I also think the size is perfect. Onc eyou go back to smaller form factor you realize that the large size is overrated and you dont really need that much large device.
Low resolution was great choice from samsung if you dont use binoculars when you're using it you can't discover anything. Also it affects great buttery life so if you want sharper display (my opinion is that is unnecessary ) take g4 or something with this absolutely unnecessary thing .. also the performance is better cause the cpu dont have to count so many useless pixels like with fhd or 2k ...

I agree. I still prefer the amoled of the alpha overall since it really has great visibility, viewing angles and colors. The best thing is the responsiveness of the alpha due to the 720p.

If I hold the G2 and the alpha about a foot from my face you can't tell the difference, but I'd rather have a 720p display then 1080p just for the battery life, I think anything over a 5 inch display should have 1080 though
Thanks OP for the Review.
Agree that Camera is a little off compared to S5 it is probably same sensor as S5 BUT Samsung intentionally dumbed it down to 12 Megapixels to not compete with S5.
For low light indoors- move exposure to plus two (+2) AND use picture stabilization BUT picture stabilize takes a lo-o-o-ong exposure so rest the phone on something while you hold it and voice actuate to avoid motion- still not great like S6 but much better.

any reason to get this instead of the z3?

Im in the market for a 7 or 8 inch tablet, but upon searching google for the best android tab every site is raving about the z4 tablet.
Is it really that much better than the z3?
i doubt no matter how light it is, that ill feel like an 8inch tho
For me bigger iswhat i need . MOvies and animes.
Butit bcame a hassle when cant potrait lock

it mainly depends what size you prefer. obviously the Z4 is a little bit more cutting edge with a higher res display, faster processor, better camera, but both are lovely tablets that can still run anything at their respective resolutions.
i always thought i'd go for 7-8" tablets when i bought one because they are a good portable middle ground, but phones are already quite big these days so i went for a Z4 so it actually makes a noticeable difference in experience compared to the phone, and the Z4 is one of the lightest 10" tablets ever made and as a result feels really easy and comfortable to hold even in one hand compared to other 10" tablets that might have given you feeling that they are too big.
Ive played with a samsung tab s 10.5 (its pretty light too) and i just prefer a smaller footprint. My old nexus 7 was the perfect size but im willing to go up to 8inches if the z3 is the best smaller android tablet
I've got both and surprisingly the performance of both isn't too different to each other, even though one has a QualComm 801 32-bit v 810 64-bit. I think there are still optimisations yet to come for the Z4.
Its down to screen size for now and if you really want that expensive keyboard. For me, yes, 10.1 inch screen for fun + work / productivity is great. Z3 is still an excellent tablet.
