Pages deforming when scrolling - Nexus 10 Q&A, Help & Troubleshooting

Hi,
Have you ever noticed that when you scroll for exemple internet pages there is a little deformation of the image ? Like the text were warping, and especialy in portrait mod.
Take a look at this video: https://www.youtube.com/watch?v=-4-tKflikYY&feature=youtube_gdata_player
Do you know if it's hardware or software problem ?

I was wondering the same thing. It's due to how LCDs refresh, top to bottom, line by line. Given the fact that our display is so dense with pixels, and the GPU isn't extremely powerful (it's a tablet after all), this is bound to happen.
It also happens on iPads, so don't think it's exclusive to the N10.

I noticed this too back when I had my N10. It was very pronounced when scrolling in portrait mode. I thought it was another flaw until I had to go back to the HP Touchpad (running android) and noticed it too. But it was very hard to see on the Touchpad. Like stated before, its because it is pushing all those pixels.

It's not really disturbing but, i don't know if it could ever be fixed or we just have to deal with it...

I had a little freak out about this when I first got my N10. I had it on my galaxy tab 7+ and thought it was just an issue with that tablet, turns out its the refresh point of the screen and some people are really sensitive to it.
Anyone know if phone screens refresh top to bottom in portrait mode while tab screens refresh top to bottom in landscape mode?

I always thought that would be part of the butter project?

Has to do with the combination of a very high resolution screen with a gpu that is not strong enough or optimized to power it. You didnt see this issue at all in the ipad 2 but did see it (albeit slightly) in the ipad 3 due to the huge increase in screen resolution from the ipad 2. The issue is also not in the ipad 4 at all, the increase in gpu performance stopped it from happening. The issue is pretty prevalent in our nexus 10s and I definitely notice it but its not as jarring after awhile.

are google going to "optimise" this then? it is rather annoying

That's pretty weird. I've been using my Nexus 10 since early December, and never saw or experienced anything like this. The youtube video also looks pretty strange to me -- I don't have any of the lag in scrolling that is apparent in that video. In the video it appears that something is really eating up cycles in either the CPU, GPU or both. My own N10 appears to be much faster -- no lag or delay like the video shows, and none of the deforming or skewing that shows on the video either.
What are you guys looking at that "deforms" when you scroll? Do you developer options enabled that might affect video performance, e.g., Transition animation scale modified, Animator duration scale, Disable HW overlays? Having trouble reconciling my own experience with the youtube video and what I'm reading in this thread. I can't duplicate any of it on my end, regardless of the website or document I'm browsing or scrolling over...

Its not so much because of the GPU. Its the screen limited by the 60hz refresh rate. This can be seen on a desktop if the monitor is in portrait mode and you can find a page that with scroll @ 60fps.

Nexus One - XDA Owner Reviews

Now that people are starting to receive their Nexus One handsets, it would be really good if there was a single thread where people could post their first impressions, then a mini review after a few days of use.
So far I can't see any threads like that on this forum, only the one logging existing issues with the N1. This will be a really helpful set of opinions for people like myself who are WinMo owners potentially considering a switch.
Me from another forum first impressions....
NoHD recording or playback.
Yes this sucka is FAST. Im convinced engadget rigged the speed test. The loading of websites is insanely fast.
MultiTouch/Pinch Zoom on Dolphin Browser is fantastic!
MUCH better than Iphne for the simple reason text will format itself to the display once pinched in or out. I cant fathom how people overlook this feature.
Homescreen cards are useless.
Homescreen crawling with live wallpapers ((especially rain)) is slightly choppy at times. Regular wallpapers smooth.
Creepy moment....Maybe I overlooked something I did.. but how did camera pics from my G1 appear on my Nexus One gallery ???? Im seriously baffled. ((drop box)) is the only info I have. Maybe Its in picasa ?? Need to check this.
App installation ?....insanely fast..serious. Its done quicker than you can exit out so far. ((wifi))
Screen is gorgeous.. I will say this. It may not WOW you at first. But the second you go back to Iphone or another phone.. it REALLY hits you how sharp this phone is. Similar to dvd to HD. Biggest difference is when you go back and realize how blurry it was.
Any unboxing vids?

Did you ever upload your G1 camera pix to Picasa? Gallery on the Nexus One (2.1) seems to pull/sync albums off Picasa now...

First impressions after a few hours:
FAST!! (especially coming from the Hero). I was download/installing apps in the background and didn't notice any slowdown.
The screen is awesome. Not just the resolution, the colors are really good. OLED is worth it.
Different hardware button order on the bottom: Back-Menu-Home-Search on the N1. Not a big deal, but I had assumed that Android would come with a recommended button layout. Oh and the buttons are capacitive sensing, not protruding rubber buttons.
After about 24 hours..
FAST, FAST, FAST... app installs are ridiculously quick. As mentioned earlier, I don't know what Engadget was doing because the browser loads everything super quick for me. Maybe they should have ran multiple tests beyond their cluttered mess they call a website.
Transitioning between homescreens can be done by touching the bottom left and right, which show dots to indicate where you are. Center screen has two dots on each side, if you click the right dots you'll have 3 on the right and 1 on the left, click to the right again and you'll have 4 on the right and 0 on the left. hard to explain, but I like it better than swiping.
Some apps need to be updated to 2.1, so I'm missing some functionality but I'm sure that will be taken care of soon.
The screen is GORGEOUS. I spent over an hour last night reading a large pdf document and never felt any eyestrain whatsoever. I'm sensing great E-reader possibilities here. Further, the battery barely lost any juice while the screen was lit up for such a long period. Battery life has been excellent so far, much better than my Ion.
Speech-to-text works well so far.
Call clarity has been fine, but I've only talked for a few minutes.
No radio issues, showing over 1mbps here in the DC area.
N1 on AT&T
I'm stuck on ATT and with wifi it is extremely fast not much faster than my sons 3gs to compare with. But definately faster and smoother. I thought that edge would be terrible and it is slower of course but surprising noticably much faster than my G1. Maybe a better radio or just the horsepower. I have wifi at work and home and don't have a lot of idle time except maybe at the airport (which has wifi) so I'm ok.
At this point I don't see anything on the horizon to top this for a while.
You know you want one and you deserve it!!!! Do it!!! Yup, even on AT&T !!!
FAST FAST FAST. got this like an hour ago and sprang out of bed (SNOW DAY!)
anyways it's super fast. like 10 times faster than g1. you hit install and it's done. you click something and it's up. multi touch in dolphin is crazy. cant wait till tonight when cyanogen includes MT in regular browser.
complains? have to get used to top button / lock screen. i also have to agree with engadget that the touch buttons seem to be higher than they should be. as in for say HOME, you have to hit the top half of it really close to screen for it to work, if u hit too far down it doesnt. and too far down is too far up IMO.
BEAUTIFUL. screen is gorgeous.
camera takes pictures like instantly. and even autofocuses. no dedicated camera button tho .
not sure about sound quality. talked to cousin and it seemed maybe worse? idk i have to wait and see.i dont like that its microusb and not miniusb but that's not really an issue.
but seriously it's ridiculously responsive and awesome and fast and worth my money . onscreen keyboard works great especially in landscape.
Hello guys and compliments for yours purchase.
Can I make you some question?
Video resolution is 720x480 but how much frame for second?
Can you see flash site? I read that adobe flash 10.1 working on nexus one, I see a video.
It's possibile to add a T9 keyboard text input like nokia 5800? I see a program "better keyboard" made this.
Thanks you guys
cboy007 is the onscreen keyboard multitouch?

GRR. no its not. it's not that big of a deal for me and also you can count on either an update making it MT or another keyboard just using it's API's. the next HTC_IME might be MT for all we know.

not sure the FPS...i can post a test video for you in a little to check it out or look at one already posted. it's better than other phone but not amazing...
no flash YET it's coming soon as an update but right now there is no flash...
better keyboard or HTC IME willl allow for t9. and idk what t9 you mean...the normal keyboard has predictive to some extent but if you want phone keypad predictive go with better KB or HTC IME. i'm seeing if the current HTC IME works in a little.
The Nexus one is absolutely amazing!! I came from 32b sapphire(my touch). This phone is probably ten times faster at loading apps and navigating around. Internet browsing is insanely fast, its pretty much like browsing on a pc. Typing on the android keyboard is actually pretty good, if I type as fast as I can the phone does not miss a beat, I tested hitting 2 keys at the same time and it always picks up both of them. I have never noticed the phone slow down one bit even when it is running 20+ apps at the same time. Almost all the apps I had for the Mytouch have worked very well on the Nexus. Orientation is almost instant, and the camera takes pics really fast as mentioned above. The screen is beautifully clear and functions well. So far I'm very impressed!

the video resoultion is 800x480
screens dfont have fps but rather i think you mean to say refresh rate. the refresh rate on OLED displays is very high.
It is possible to add a T9 keyboard. Cyanogen will soon release the HTC_IME keyboard for nexus one and it supports this feature.

No, he's asking about the specs if you're taking video with the camera. It is 720x480, but I don't know the fps.
oh the camera? well still images do not have FPS, video recording is 20fps. (Source)
I've had mine for about an hour now and I LOVE it. The screen is amazing and very vibrant . The phone itself looks and feels great. When it changes to landscape view it is SUPER fast, there is pretty much no lag to speak of.
My biggest issue so far is the fact it doesn't use the normal mini usb for charging. The only reason I have an issue with that is the fact I have mini USB chargers everywhere in my house.
Besides that the only other thing I don't care for is the automatic screen brightness. I like my screen bright and it tends to get a little to dim when it's on auto matic.
It's the best phone in the world. So snappy, integrated with google. This is the Android experience.
Engadgets Browser Test....... BS
I keep hearing mention of the Engadget's browser test video between the Droid, N1 and IPhone. What they fail to mention is that engadget's site is safari optimized, yes apple's safari! Try any other website, and you'll have vastly different results. They keep saying that the Droid's and N1's performance was "embarrassing", the true embarrassment is the lack of objectivity that engadget has shown when regarding anything apple!
Wow, I didn't know about not charging off miniUSB...that's kinda a bummer, that's how I always charged my G1. Guess I'll have to make sure not to lose my official charger.
I've had it for about 90 minutes so far. Reading Engadget's review made me afraid I was going to have buyer's remorse, but the two things that bothered me the most in their review turn out to be non-issues. I tried out the screen in the bright Los Angeles sun and, at least when the brightness is turned up, it's still usable. The screen reflects a lot of light though, and the glare can make it tough, but you can still see what's on the screen through it just fine. Also, no multitouch is a bummer in most cases, but the multitouch on the Dolphin browser is just as good as the iPhone's, nice and smooth. Finally, page loading for me has been plenty fast, and despite Speedtest saying there's no real change in download speed, it appears to download pages much more quickly (I'm assuming it's due to the page rendering that much faster).
Everything is fast, boot times appear to be under 30 seconds (I didn't time it), no real lag so far, the keyboard is very responsive, scrolling is smooth as glass -- I'm not regretting the purchase in the slightest, though I am feeling a little bad for my poor G1, he served me well for quite some time!

For those that have a XOOM in hand, what don't you like?

Title says it all, what doesn't live up to your expectations? We've seen in the reviews that the screen isn't viewable in daylight and the buttons get stuck. Have you experienced this? What else?
I've only had it for a half hour or so but the display seems no different than my iPad that I had before it (in terms of visibility in different lighting conditions).
What buttons get stuck? I only see a power button on the back...
Anyways, I have no dislikes at the moment aside from the lack of microSD support right now.

Engadget's review said the volume buttons would get stuck from time to time. Also said the power button got stuck, forcing a shutdown.
Please compare and contrast with your iPad. Does the pixel density look worse? Have you tried reading a book on it? Have you seen it in direct sunlight (some reviews say it's completely unusable in direct sunlight)? Are the speakers bad, being on the back side and all?
It's cloudy out today so I doubt I'll be able to check in sunlight. My iPad was unusable in direct sunlight.
Reading a book in portrait mode works wonderfully (I use Kindle, not the google app). Worked great on my iPad as well.
Pixel density... seems about the same as the iPad visually. If I look for them, I can see pixels... though I have to stick my face within a foot of it to do so.
As I'm at work, I'll check the speakers later... I can't compare them to my iPad since I never used them before. I use a bluetooth headset for everything (phone, laptop, tablet).
I played with the volume and power buttons a bit, but I couldn't get them to stick.
No serious problems so far, though in some ways, the GMail client is less intuitive than I had hoped. For example, on the web, my priority inbox will move read emails to my inbox, but on the Xoom, they stay in my priority inbox, just marked as read. It makes for more clutter than I prefer.
But I'm an early adopter. I expect stuff like this.
No button issues at all.
don't like power button placement, other than that very happy with it so far, the size adn shape and screen ratio is great
great so far here with a few issues.
Power button placement doesn't make sense.
Browser loads mobile sites by default, with no option to change the user-agent (that I can find anyway)
no ad-hoc support, but I knew this from the start (hopefully can be patched soon)
and on a side note, the screen seems a bit on the lower quality side, BUT I have not yet removed the plastic film, it looks crystal clear, so I cant imagine it will have much of an impact, but it could just be me.
Button placement for sure. Trying to learn my way around it, doesn't feel as intuitive as my ipad but I am learning Also hate the power cord situation.
Speaking of power cord I don't get that either I mean WTF Moto looks like they stole a charger from Nokia...
The d!ck who spent 20 minutes trying to sell me other sh!t I didn't need at the VZ store.
[UPDATE]
Guess I'll encounter that d!ck again because i'm noticing a slightly discolored band running down the edge of the screen on one side so I'll have to take it back! Fudge!

This is why I'm waiting outside for costco to open. They don't push as hard.
Just got home with my new Xoom...
Display - Pretty good but not nearly as great as the iPad's.. nor is it as bright as the iPad. Pixel density looks A LOT like the iPad.. I can't really say the Xoom is any sharper than the iPad.. Whites look much better on the iPad.. they definately have a much higher color gamut and contrast ratio on the iPad. This is disappointing considering how much the Xoom costs off-contract. The Xoom screen looks nearly identical to what Samsung uses on their Galaxy Tab 7". Viewing angles are "decent" but again, not as good as iPad. I would say they are using a cheap PVA type panel, not IPS on this unit. PVA is still much better than TN at least.
Weight - Same weight as iPad.. so to me, it feels too heavy for it's size... but I think the Xoom is much easier to hang onto/hold because of it's widescreen nature'd body.
Speed - Depending on apps I guess.. or how optimized they are.. Angry Birds Seasons (the tablet version) runs like crap compared to Angry Birds on my Galaxy Tab.. not sure why.. Web browsing is a real treat.. Definately renders web sites faster than the iPad.. content is ready to explore at a much faster pace.. However, scrolling isn't as nice as it is on the iPad.. I don't know why Android can't get scrolling anywhere near iOS's Safari. Scrolling is choppy and clunky depending on how many pictures are needed to be shown on the screen at one time. Quadrant scores LOWER than my Galaxy Tab.. Could be Quadrant's not optimized well enough for the Tegra2 platform.
Battery Life - I will have to edit this in later.. my Xoom came out of the box with 77% life..
Interface/UI - I actually like Honeycombs UI.. the quick-softkeys are delightful to use.. especially to multitask with.. Flying between apps is instantaneous and snappy.. much faster than iPad's multitasking.
I'll post more later.. going back to playing with the Xoom.
Edit: Created a new thread on my thoughts so that people can ask anything they want to know.
Power button placement is pretty bad. It's especially an issue with the Moto Portfolio case. That thing, although well manufactured, is poorly designed (covers all the charging/usb ports.)
The system is a little laggy in some parts.
Very few tablet specific apps. So, Kindle app for example, looks fine but isnt utilizing the extra resolution. Ipad version will show two page layout, Honeycomb wont (for now.)
I don't see where people are getting the menu lag from, i've had absolutely none so far. The power button placement is PERFECT, are you guys kidding? The device was designed for optimized landscape view and when you hold it with both hands, it's right there ready to be pressed without having to readjust. This may be different for portrait but I don't plan on using it much.
Connectivity issues with android market as usual but thats typical, they need to fix that, asap.
Angry Birds Seasons is NOT laggy, again, don't know where you're getting that from.
And i'm looking at my Ipad and the xoom side by side and the screen quality on the Ipad is not "considerably" better. Slightly, if even that.
One big negative, lot's of force closes when I try to multi task a lot. This is VERY disappointing, and if it continues, i'll be returning the device.
The screen brightness/quality/angle view is not as good as the iPad, it seems heavy for its size, although the screen is bigger then the iPad it seems smaller because of the aspect ratio. Battery seems to drain fast, maybe it needs to be conditioned. Occasional lag in the UI.
On the plus side the speaker is pretty loud.
To summon it up: currently not overly impressed.
I hate that the browser shows mobile sites. I don't see an option to change the user agent. It's stupid to have to install a different browser, but I guess that's what I gotta do.

Go to: "about:debug"
You won't see anything. Then go into the settings and there should be a debug section where you can change the user agent to desktop. Someone posted this in another thread, worked well for me.

Thanks! The setting in debug is called uastring. Took me a while to realize.
Love the general feel and speed, mostly, of it. Most apps are faster than my X. Still playing with them.
Sling player (one of my favorite apps on my X) is useless, dial-up would work better, freezes and jumps. Video/audio NEVER in sync. Sometime emits a loud screech when un-freezing. (w/3G and all bars)
YouTube is terrible (same video compared to PC), like its always out of focus, contrast levels WAY off.
Hate the placement of the ports. Have to hold it upside down to use when charger is attached. I would have done this when placing it in the portfolio case (cheep and clumsy feeling) but then you cant get to the power button! DUMB, DUMB, DUMB design.
Cant find the setting to get the display to not time out when it on charge!
Cant get into my company website (can with my droid x) I think the new browser has TLS security set and I need to turn it off.
Generally I like it and will come up with work-arounds for most of the issues it's the first one out and both xoom and 3.0 need work and will mature with time. I do thin I will keep it.

I remember doing that on my phone. I don't like that it loses that setting on a reboot.

LCD ghosting

One thing I have noticed about my Xoom is that the LCD seems to have a fairly low refresh rate. This is most evident with the blacks 'smearing' quite noticeably when the screen scrolls. You can see this effect in the game Angry Birds by scrolling left and right (watch the yellow birds especially). I also noticed watching a movie that had a lot of dark scenes in it.
Has anyone else noticed the blacks smearing/ghosting on their displays? The moto website offers no specs on these displays at all, other than resolution. I wonder what the refresh rate really is? Anyone know?

Whoa, but the thing is I never noticed it LOL. I guess it can't be that big of a deal is there is only 2 small threads on the subject.
I put my xoom next to my computer monitor and I was amazed by the results. One good thing is that my computer monitor has zero ghosting issues.

A comparison against a computer monitor might not be fair if the monitor is a TN panel. They generally have quick response times, but poorer viewing angles and colour depth.
Most people won't notice the ghosting under normal circumstances and it's going to be a non issue for them. It's entirely possible that other tablets are no better, but I have nothing to test against right now. Although I am quite curious how the others perform in this regard. I have watched Futurama episodes on the Xoom and they looked great, but Harry Potter not so much because of the darker images. I had been wondering if some of these tablets are using the same LCD panels (except for the Asus which has an IPS panel).

Ah ok, I do have a TN panel so that explain things.
I might test this out on the iPad 2 + Transformer during my next best buy visit.
I'm going to visit staples tomorrow and do some testing with the Acer and Asus models. I have to return the Moto folio case while I am at it... We don't have the new Samsung or Toshiba tablets available yet here in Canada, not until the middle of August.

Return it. Now is the best time, don't wait until your return period is over and then become one of the habitual complainers...
I tested the Acer and the Asus tabs at staples today. The Acer had the same amount of ghosting as the Xoom which leads me to believe they use similar display panels. Although there was still some ghosting with the Asus, it was considerably less than either the Xoom or the Acer. The IPS panel Asus uses simply has better refresh rates it appears.
Conclusion? The Xoom is still a great tablet. The GPS works fantastic, the sound is good and the build quality is excellent. Buying another tablet is not the answer because every single model has its own strengths and weaknesses. It will drive you crazy if you keep trying to find the perfect tablet - one doesn't exist (yet). You have to buy one where the strengths suit your needs and you are willing to accept the weaknesses as just the way the tablet is made.

I noticed it in the day one.. it is like the plasma tvs.. but i dont think it is about the pyhsical refresh rate of the screen.. it is more likely about the frames that the gpu creates per second.. after i realised ghosting i put my xoom next to an ipad 2 and at first i could not see any ghosting in ipad when scrolling through the menu icons.. but then instead of throwing the icons with my finger i moved them slowly and there it was.. the ghosting of ipad 2 was even worse.. so i guess it can change with software adjustments..
I ran the test on my xoom and it did ghost. I then ran it on my nexus one and there was no ghosting at all.

Is there a way to change didplay refresh rate in android os?
hello, this is a hardware problem and and there is no software possibilitie to solve it. To answere your question, even if something would exist to change the refresh rate in android, that would not really change it because an lcd panel only works with one unique refresh rate on the contrary of the old crt's monitors.
You're right, i forgot it! And is it possible to change the fps of the desktop?

Any body have strange scrolling effect in portrait mode?

I love everything about my N10 but I'm coming from an IPAD2 and used to using in portrait mode. When I scroll up or down it makes the screen have this wobby effect like a wave kinda. If for example I scroll down a vertical line on the webpage looks like it bends. Kinda like that optical illusion when you wobble a pencil and it looks like you are bending it but its really straight. Anybody notice this?
I'm thinking its just that an optical illusion because of the narrow screen real estate in portrait mode. Not as noticeable in landscape mode but if i really look for it i can kinda notice it but not enough to bug me. I can always learn to use it in landscape mode primarily. But just curious if anyone else notices this effect of scrolling.
You are no imagining it. It exists. It exists on every display ever made. However some displays have it more (or less) pronounced due to the GPU /drivers. Higher resolutions and slower GPUs will both make the effect more noticeable. We have an ultra-high resolution and a GPU that could be faster, so that's why you can see it so easily.
Ahh ok. Thanks for the explanation. No wonder I don't notice it on the IPAD 2. I guess adapting it is.
Glad I found a thread on this, just making sure I wasn't the only one. When scrolling pictures or text I definitely can see a wavy lag in other parts of the screen.

But also the Mali604 is new so could be software related (drivers).
I don't see this on my screen, not sure what you guys are referring to, but I tried replicating it. Is this something that can be captured on video?
Referencing the thread I made for this issue on mine: http://forum.xda-developers.com/showthread.php?t=2008634
I have a video and picture on the first page showing what I'm talking about.
it's like scrolling jelly... one side scrolls a bit faster than the other side... almost as if vsync wasn't working properly

yes it's exactly like jelly. I hope it's a driver issue and not hardware limitation issue.

Nexus 10, is it that bad?

I've been reading for quite awhile because I got myself one (it's still on the way to me, so no hands on yet). I got it mainly because it's a Nexus and I'm done with those 3rd modifications on top of vanilla.
However, I'm getting really mixed comments from all of you guys. Some said it's really nice, some said it's the worst tablet. Although things are always going back to people's own preference but from what I read, 4.2.2 did give lotsa headaches to users mainly because of leaked memory and so.
So users, can you give me your truthful comments from both pros and cons? I can only get the device by next week and after that, it will be my time to list out my very own pros and cons.
Thanks and cheers!

Yeah, you better cancel your order because some random a holes on the internet did not like something.
Well, the problem is, I can't. Plus, I'm still quite skeptical about the reboots and I have faith that it will be fixed with the update soon.
Are you one of the users?
I'm definitely ok with a bit of problems and it gives me perfect reason to root and tweak it on myself although some do claim that, it should work perfectly fine out of the box.

I'm running stock and can definitely say that the surfaceflinger memory exists. It becomes obvious when you play multiple videos (streaming or video files). When you do other activities this bug is not readily apparent.
I also from time to time get random WiFi disconnects, which are easily fixed by toggling the WiFi off/on. With that being said I really like my N10 and am using it for more than I expected when I bought it. The display resolution, I/O speed and CPU are all outstanding.
At least the memory leak can be fixed and I read that the surfaceflinger driver developer already has it ready. This gives me hope that Android 4.3 will include the fix. The N10 used as a media consumption device is very good/excellent. I am not disappointed with my purchase.
My laptop at the about same price point (after including N10 accessories) has not been turned on in over three months. All my news reading has move from my desktop PC to the N10. I was surprised at how smooth that transition went.
The only thing that really bothered me about the Nexus 10 is how it could throttle and lower CPU clocks under general usage (general being like playing a game). But then again, the Nexus 4 also does this...
Aside from that though, I find the N10 pretty awesome
The light bleed at the bottom right is the only thing that has bothered me much, but that's because the threads here pointed it out and turned on an OCD switch in me. After almost a month, I had my first two reboots last night, both while watching an hourlong streaming video from a TV network site (using Firefox with Flash). Other than that, couldn't be happier with my N10.

Here's the thing that I always talk about. It's a nexus and all problems will be solved for sure by Google itself. With such a good display as well as the A15 architecture proc, it's really a beast and let alone the pure vanilla android.
People are a little bit over exaggerated about the bug, IMO. We receive the newest version and bugs are bearable with me. At least buyers should be aware of the firmware is always the latest which might be a little big buggy. Few positive comments over here are really making my day.
Another thing that bothered me is available RAM. Google states the tablet has 2GB of RAM, which is true (there is 2GB worth of RAM chips installed on the motherboard technically). Before 4.2.2, about 400MB was reserved specifically for the GPU, which is the largest amount of RAM I've seen on any Android device, so that left 1.6GB usable. Not that bad, and it still rounded to 2GB (most other devices though to be fair take like 200-300MB; but the N10 is driving a pretty beefy resolution)
WIth 4.2.2, the RAM reserved for the GPU doubled to 800-some MB (836?). So now the total RAM that the user can use on their own is 1.2GB. No longer nearly close to 2GB.
I guess nothing can really be done about it now, but I don't understand why there just isn't dedicated memory just for the GPU, or why Google doesn't just advertise how much RAM is actually available to use. This isn't an issue at all on most other devices, since the missing memory is usually a small amount, but when almost half of the advertised RAM is missing and not even user-configurable (most computers with IGPs sharing system memory at least let you specify how much you want to dedicated to it)... I find that pretty shady :/
On the other hand, I don't have any out-of-memory problems though (aside from the surfaceflinger thing), so it doesn't seem to be an "actual" issue.
I haven't really noticed anything wrong with my nexus 10 I think its great and fast. Also 4.3 is going to be released soon which should fix any software related issues and make it even smoother . I don't use my tablet as much as others might so maybe that's why I don't notice anything wrong. I generally use it 2-3 hours a day and the only thing I hat is the charging time which feels like forever and that it has a phablet ui rather than tablet look which wastes a little screen space. What they should do is get rid of notification bar and combine it with Nav bar like other tablets

Use full!screen and LMT/PIE and get all the screen resolution back (full 2560x1600). full!screen gets rid of both bars and provides a notifications pop-up while LMT/PIE can be configured with all the navigation buttons plus much more. I've been using that combination on rooted stock for months now and would never go back to the waste of space that either bar takes.
I like the clean AOSP browser in fullscreen mode plus thumb controls but it does not always paint properly when used with full!screen (artifacts where the navigation bar used to be). I switched to Ocean browser which is really AOSP with a new UI and that fixed the fullscreen paint issue.

If you can deal with random reboots don't worry about it. It really is something that depends on use. Watching YouTube via chrome will exacerbate the reboots. The actual app doesn't seem to eat the memory. However for my use I can't have it rebooting in the middle of a meeting or trying to dial into work so it has become something of a paperweight. I know how to consume the memory and how to avoid it but it will still eventually reboot. If your using it for goof off purposes instead of productivity you'll be fine. Also, please don't be an Android/Google apologist. They've had 6 months to fix the issue. And they don't market it as a device with buggy firmware that will reboot. If they called it Nexus 10 developer edition I'd agree with you.

Pros:
- Highest resolution tablet on the market, nobody else comes close, even latest iPad has 25% less pixels. I had a Thunderbolt display at work last year and loved working with so much screen real-estate, well, this tablet has even more pixels in 10" than that display had in 27".
- First Android device with beefy Cortex A15 CPU, the Exynos 5 Dual, still the only tablet on the market with A15.
- I actually like the build, fairly thin and I like the sticky material on back.
- For $500 for 32 GB, the one I got, you won't find any device with such high-end specs.
- Android 4.2.2 is usually fairly snappy, sometimes I go back and forth between the home screen and the application drawer just to see the snazzy zoom-in/zoom-out animation and how fast it is.
Each one of these comes with drawbacks however.
Cons:
- You want a high resolution, you have to pay for it with power draw. The display consistently accounts for about 60% of battery usage, even though I keep the brightness at about 30% under light and dial it down to the lowest setting in a dark room. The colors are good but a bit washed out, particularly when compared to an iPad. I wish it had a matte display like my Zenbook, as the glossy display does catch reflections, but I'm not sure that's possible for a tablet.
- The Exynos 5 CPU takes more power than it should and runs somewhat hot. Not as hot as the Tegra 3 in my HOX+, but fairly warm.
- I was surprised how heavy 1.3 lbs felt from the first time I held it. The battery in this thing is huge, 9Ah, compared to 2-3 Ah in most current flagship phones, like the One or S4. It probably had to be so big with that power-sucking display and CPU, but it adds weight.
- The build is a bit creaky and sometimes feels like you have to snap particular pieces back into place, probably to be expected at this cheap price.
- Android still has times when it starts lagging and everything you do takes a second or two to register. These slowdowns often come out of the blue and you're never sure what's going on. This is a mobile OS, so prepare to be frustrated when apps are backgrounded and cached data is lost, particularly if you're expecting something closer to desktop performance because of the specs. The known memory leak in 4.2.2 exacerbates this problem.
I'm happy with my Nexus 10, as I enjoy the high resolution and don't use it anywhere as much as my ultrabook. Now that I know about the memory leak, I may start trying to use it for web reading again, which I had to give up on because it was unusable when Chrome would start reloading every page for no reason. Now I know to reboot when that starts happening, so I at least have a workaround till they fix it.
I love the tablet, for the way I use it - which may be considered light use by most here - it is perfect. The memory issue is real there is no doubt about that. But it is also easily avoided. I reboot my N10 with a tasker profile once during the night and that is that. However I game on it very rarely and use it mostly for streaming movies or just browing the web. One reboot each night seems to be enough to not make these issues appear.
Having said that I have none of the other reported issues, no random reboots or whacky Wifi - I turn Wifi off when the tablet is not in use - but I am also running SentinelRom which seems to be ironing out a lot of the smaller issues. With this ROM scrolling for example has become a silky smooth affair.
Battery life is excellent, much better than the boards make it out to be. I rarely use the N10 with brightness above 25% because it is already so bright on that setting there is no need for it. There may be light bleed - hey it's an LCD after all! - but I never notice any the way I use it. The display is gorgeous in every way, shape and form and I really really like the fact that putting it on lowest brightness makes it really dark. This is perfect for using it in bed at night without getting eye cancer.
With the POGO charger the tablet even has decent charging speed.
Regarding build quality I cannot complain at all. My tablet is not creaky in the least. I had a TF101 which was way worse. I mostly use it with a Poetic smart cover and couldn't be happier. The weight is of course noticeable, but then again this is 10 inches of hardware, it will never feel light as a feather.
Still there are some undeniable software issues still present. The memory leak being one, some issues with scrolling (except when using SentinelRom) being another. But I have yet to see the "perfect" android device which so far does not exist. Google still has a lot of work to do.

Not getting the random reboots you speak of. Use my tablet 3-4 hours per day, sometimes more, and do not recall having 1 reboot. AOSP browser closures, yes, though with newer versions not as much. Have 2 Nexus 10 tablets, one stock, one sw display itching between SaberMod and Buttered AOKP.
Had both theTF101 and TF700. Went with the ASUS because of it's IPS+ display and SD card slot. 5 weeks after receiving, had to send it in for charging issues..oneof my main problems with the TF101. For the slight amount of money more for the Nexus 10, it is a much better option. Check out Swappa.com-can typically get a slightly used Nexus 10 for a really good price

You left out my next sentence. It depends on use. I can duplicate the surfaceflinger issue with eventual reboot on stock CM, buttered AOKP, and rasbean. Obviously we use the tablet differently.

I also left out the statement that got me to post originally: "However for my use I can't have it rebooting in the middle of a meeting or trying to dial into work so it mass become something of a paperweight." As the OP was curious about the reliability of this tablet, I wanted to offer a different perspective.
As a tablet for business, I use it for surfing (quote obtained from website, along with any needed client info), note taking, power point and excel, E-mail, along with a few other things. In a given day, I may spend 3-4 hours, while in client homes, using my tablet. So yes, we may use these differently, but for any "business" function I have thrown at it, it works fine. I also do not do many video presentations, which may explain why I do not experience the same issues as you.
