Hi guys.
Before buying my A510, I used to have a SGT 10.1. I sold off my SGT 10.1 2 weeks before getting my A510, so I was never able to do side-by-side comparison between the two.
However, judging by the response in the forums at that time and by my personal usage, it was clear that the Acer tablet had some serious sensitivity issues. I couldn't confirm how bad, but it was bad enough to be noticeable by me based against my SGT 10.1.
To me, the worst thing is when putting the tablet on a hard flat surface, like a table. This is where the sensitivity, for some weird r!eason, takes a very BAD hit. I just got a Note 10.1 yesteray, and used both side by side. The Note could flawlessly take input when laid flat on a table. But not the A510.
Any idea why? Do try if your tab takes a hit when placed on a flat surface and let me know.
Thanks
I had an A510 that I returned for just that reason; sensitivity not only took a hit, it became almost useless when laid on a table. Problem was compounded by a screen protector. A700 seems much better. However the most recent update (1.029 -> 1.057) actually made things worse as far as the touch screen. For a while I flashed back to 1.029. Then I decided to update to 1.057 and root, and now I am using Acer Liquid Settings program which requires root & seems to help sensitivity. I am typing this flat on a table with only 1 or 2 missed touches for this reply, all in the 1st sentence.
Edit: There is a YouTube video that illustrates this problem in the A510 Search A510 problem on YouTube.

Indeed, I have EXACTLY the same problem as that in the video. The actionbar is TOTALLY unusable on a table. When I lift and use it in my hands, things are much better but still very much worse compared to other tablets.
Now, the thing is, from what I read, an update from Acer caused this issue. Can anybody vouch for that?
I got my tablet in mid-June, and by then it was running on the latest version. I've not gotten any new updates to fix this issue. Assuming it is a software problem, why hasn't Acer issued a hotfix? Also, this must mean ALL A510s are affected right?
screen protector?
ok, may sound a bit weird, but i experienced exactly the same "issue" on my a700. if i use the tab in bed or in the stand i got no touchscreen response. but this inresponsiveness has startet sometimes after mounting a screen protector at the tab. it just takes a while, until i recognised this behavior. travelling around the last weeks and was trying to navigate through the music library at the hotel brought the problem up first time.
since i removed the protector foil, the touchscreen response is back in all situations.

There have been past threads on different devices that point to a grounding issue when this occurs. Your body is a conductor when holding the tablet so it works better. If the device is grounded properly then there isn't an issue either way. If your saying this was the result of an update then that's better then a hardware issue since it can be fixed much easier, once the company is made aware of the issue of course.

Yes a software issue can be fixed more easily...
IF the company decides to acknowledge the problem, act on the information and then go to the (likely considerable) expense of creating and releasing an update to address the problem. There have been many reports of this touch screen issue in the A51x & A7xx Iconias throughout the Internet especially, but not exclusively, if one is using a screen protector. Amazingly Acer claimed to address this in most recent OTA update for A700 (1.057), which was stated to address touch screen issues; it only made them worse on my A700. Go figure.
So I have the A700 and do not find any difference in touch sensitivity between the tablet laying down on a table and it being in my hands. Are you guys finding a big difference between the two?
Unfortunately it doesn't mean its perfect as I do struggle with touch sensitivity with the edges of the screen sometimes, which can be annoying as a lot off apps/browsers tend to put buttons in the corners.
Quick fix is to toggle the screen sensitivity everytime you boot up. (Change to medium then back high again, you do this every boot.)
A more permanent solution (applicable to the A510 only), is to flash NoThrills' optimized A510 rom along with the included NoThrills Kernel. This has solved my screen sensitivity issues.

Oh my God, you're so damn right! One of the first things I did when I got my tablet was putting the sensitivity to high, and I have never changed it since. Now that you mention, I put it to medium, then immediately high. Using the tablet on a flat surface is possible...my taps get registered flawlessly.
So, this means it is not something wrong with the display panel itself, but a software issue. Here's to hoping that Acer will fix it. Really weird man.
PS: Is there a code that I could tweak in the buil_prop maybe? I don't want to be flashing ROMs at the moment.
I was also wondering whether screen sensitivity could be addressed in build.prop. Anyone know?

I currently do not know of any build.prop or init.d solution. (So I guess it's more complex than I thought it would be.)
As mentioned though, I don't have the sensitivity issues anymore since using NoThrill's Optimized A510 WW ROM (The kernel was the one that fixed it I think, since I flashed Acer's stock kernel and I got my sensitivity issues back.)
So you might wanna consider flashing a new rom, or, flashing a new kernel at least.

Hello,
I am convinced that something is wrong with the Triumph. I searched for "keyboard" and "response" in the thread titles but got nothing.
Basically, the screen doesn't register my touches consistently. Is this something that is fixable by a software update, or is it faulty hardware? It's almost like I type too fast for the Triumph. But when touching a link, it often doesn't register, either, and it's not localized to any particular area of the screen. Slowing down my typing seems to help, but this is making the phone in my opinion, unusable. I have no reason to believe that I got a faulty unit.
What is the fix for this problem, and sorry if I missed the answers somewhere in the forums.

No, I have not, but I have thought about it. I've heard conflicting reports about whether that helps or not. In the past, I have not noted these screen protectors to be causing the problem. Can anyone speak with authority about whether removing the screen protector solves the response issues? It's a one-way procedure, because there's no way that I'll be able to get that screen protector applied as perfectly as it was at the factory.
Thanks

I can't speak with authority, but I can speak based on personal experience. It made a HUGE difference for me. And no, I haven't had any scratches on the screen nor have I had any problems since I removed it.
I can't say but I have notices that when my available RAM falls below 50 mb that the touch becomes less responsive, that and cold fingers.

The touch screen does lag, regardless of the screen protector. Its most apparent to me when opening the app drawer; it's hard to get the screen to roll. I think it's a combination of literally cold fingers as well as a sort of metaphorical coldness of the device itself; it seems that the lag effect diminishes as the device settles into its groove after prolonged use. I notice the lag when the ROM is 'fresh.'
I am on my 2nd T and they both exhibit the quirk. LPP and the new ADW seem to help her work it out. Perplexing little devices on an intentionally-attenuated redheaded step-network, fer sure, but virtually unbrickable, and oh my black jesus do i ever love me my $25/month, contract-free ultimateness.
I've spent a lot of time trying to resolve this issue in the TG-Reloaded CM7 ROM. Updating & rewriting the bi041p touchscreen driver in the kernel. I'm finally ready to just say it's a hardware problem, maybe a grounding issue. The interrupt sometimes just doesn't trigger reliably.
Well they're are two things you can do it increase the touch screen sensitivity,the first way would be to flash ROM or a kernel that has reworked drivers that are supposed to help touchscreen sensitivity a little.The next thing you could do that I think would greatly improve touchscreen sensitivity would be to take of the factory installed screen protector as it is very thick and low quality.
Is there any way to raise the touch input sensitivity? My A700 seems to miss quick taps, requiring at least half a second worth of tap to reliably register the input. Can this be changed?
Yes. Look in settings.

Hi there. The A510 has a bug that causes the touchscreen to not initialize correctly during boot. This can be temporarily solved by changing the setting for the screen sensitivity in the settings menu. This seems to reinitializes the screen which then works ok until the next reboot. Perhaps the same bug is also present for the A700?
You could give it a try.

This issue was one of the reasons why I brought the a510 back for a refund.
Easy to fix, and adjusting the input made things a little better permanently, but it was not as responsive as it should be without fiddling at each bootup.
Wife hated having to do it too, so back it went.
The a700 is/was on my short list, so if this is a common problem on the a700 now too then my choice of HD Android tablet got 'infinitely' easier...
I'm not having any issues with touch on my A700.
No probs here eithet

Ya, big issue. Even at the highest sensitivity it is simply not good enough.

I too had a significant touch screen sensitivity issue with the A510 and returned it for that reason. It was greatly exacerbated by the Skinomi screen protector I used, and improved when I removed that. However even with the screen protector off, the A510's screen was virtually unresponsive when lying flat on a desk or propped up in a stand, both of which modes I use not infrequently. The A510 seemed to need my fingers on the back to function properly; some (on XDA and other forums) refer to this as a "grounding" problem.
I purchased the A700 hoping that, with a different screen, this problem might be resolved. The good news for me is that my A700 has shown NO issues at all with the touch screen. I have a Roo Case matte screen protector on, (which really helps with glare and fingerprints) and the screen has responded to my every touch, whether in my hands, on a desk or on a stand.
Even though I have lost some battery life and responsiveness compared to the A510 due to the higher resolution, I am more than pleased with the A700 because of the lack (for me) of touch screen issues.
I should note that the Mobile Tech Review review of the A700 (the best review resource for tablets IMHO) finds the opposite of my experience; they found their A700 to be somewhat LESS responsive than their A510. Go figure.
Which firmware are you using? I've updated my firmware to the 1.028.00 version found in the development forum and I must say that the input sensitivity is improved with that version .... a bit. (Was running a 1.026.00 version). So it definitely seems to depend on the firmware version one is running.

The current US FW version is 1.017.
I got my A510 two days ago and after my initial delight with the device dissipated I got into testing it a bit. In 12 hours of testing (playing back medium res video on loop) I had two complete freezes requiring a hard reset. I was using Mobo player. This is just not acceptable for me so I'm sending it back today. Looking for a replacement tablet there's nothing that really fits the bill. The TF300 is very similar and I would go for that were it not for the silly speaker placement that gives imbalanced, mono sound when playing back video/audio.
Essentially, I want the A510 but without the freezing problems so my question is whether I just got unlucky with a bad device or if this is a problem common to this tablet (or indeed the Tegra chip in general). The device does heat up quite a bit but that in and of itself is not a major issue to me if it's not the root cause of the crashing. If it's a known problem is there any chance Acer will fix it in later batches of the tablet?
The A700 is a little outside my budget but I would pay the extra €70 if I could be sure it didn't have similar issues so if anyone has rigorously tested both models and can give any feedback as to the reliability of each I'd love to hear it.

Well, I bought an Iconia A510 and experienced the touch screen issues during the very first minutes of usage. I sent it back to Acer for assistance twice in a month. After a touch screen and a motherboard replacement still the problem hasn't been solved.
While I was waiting for the A510 to be fixed, I ordered a brand new A700 from Amazon.
I would have sold the A510 if the A700 had satisfied me.
The touch screen issues were almost absent, though it happened a few times to the screen to become unresponsive. The heat on the lower-right corner was there and present. I experienced a couple of reboots too (expecially during high demanding 3D games).
Due to the higher resolution, a few games didn't run as smooth as on the A510.
Watching the movies was a very pleasant experience. The screen was really great as well as the stereo output coming out from two separate and well positioned speakers.
While I was impressed with the Iconia A700, I resolved to return it back to Amazon because I realised that the only benefit I would have had from the new model was the screen resolution.
The A700 inherited all other major issues affecting the A510 (touch screen, heat and reboots).
It could be that I received a defective device. Still I haven't read very positive feedback on the A700.
Thanks. Looks like yet another missed opportunity then. As a matter of interest if your A501 is still misbehaving when you get it back, what do you plan to do?

Well, the tablet is in my hands already and like I said in my previous post it is still misbehaving. I am eagerly waiting for the next OTA to be released. There are reports that the touch screen issues have been resolved in which case I am going to keep it.
I will give it to my little boy otherwise.
Since he repeatedly bangs on the screen as long as it shows anything that he likes, I am pretty much sure he won't notice any lag on the touch screen responsiveness!
my a510 freezes too. totally randomly...black and white screen, or gray.
and then the only way is to force rebbot manually with poweroff.
i got my one replaced too, but still find this frezees...or simple app crashes...or lags
i opened a similar thread...but no answers. my firmware is italian 1044.00 wwgen1
@slrvboooh
what's your firmware build?
I returned a TF700 and replace a order again on Amazon
I just got my TF700 and the first things I do is press the screen down to see if there is a clicking sound or loosen screen problem.
Thank god it doesn't have such problems
Then I turn it on and check for light bleeding. Well, there is a light bleeding spot on the left corner, but not obvious and won't be notice under normal use.
The rest of the TF700 are fine.
Now I am waiting for the case and screen flim.
I am not going to use it until the case arrive, last time I drop it from around 5~8cm height and the corner just blend and the screen pop out. I cannot believe how weak the structure is (Absolutely much weaker than the ipad!)
Hope the case could give some protection.
Waiting for JB now

Yes, +1 on the case. It's really important to have some protective covering for this device. It's so beautiful and it would be such a shame to scratch and mar it up.
Without issues, Asus's tablets are the best:good:
Sound funny but it's true.
Do you have Bluetooth earphones to test it out with? I am happy with my tablet except for the Bluetooth audio lag.
What about lags and performance ?
Mine is perfect built with no hard ware issues, but I feel there are some software issues. I want to know is it common issues or only mine.
Some lags in main screen when first time going through them it looks like it needs time to load the pages and when downloading/updating apps from the market there are some freezes in screen and sometime while browsing using chrome the device become unresponsive and the screen freeze and I have to shut it down...
The device is great, but I'm wondering about the software issues and smoothness of this CPU

same here but i think it's more noticeable because i have a nexus which is very smooth. hoping jb solves all the lagginess.
I just received my TF700T 64GB from Amazon yesterday and no issues with the screen clicking, actually it is very solid. It does have some light bleed out on the start up screen. But any other time it is not noticeable at all. As for the BT issue, that I am not sure of since I don't have a BT headset.
I did have a Freeze and Crash with loading Glowball. Once I turned it off and back on, it didn't seem to have any issues. The lags, in loading pages I have noticed this every once in awhile, which is strange. Wasn't sure if it was my Wifi network. However I have not had any lagging to the point that it locked up the page where I would need to shut down and reboot.
As for a case, that is not for me. You purchase a device like this due to performance and how thin it is. By putting a case over it, then it is thicker like some of the competition. Besides when dust particles get behind the case it will scratch the aluminum anyway if not careful. Not quite sure how one drops such a heavy device. If you have Accidental Damage insurance on it, no need to worry. File a claim and get a new one, issue fixed.
Traded my prime in at my local BestBuy for an Infinity. Clicking around the screen and the buttons were mushy. Second Infinity the buttons were still mushy and there was a poor mesh between the aluminum back and the plastic strip. THIRD Infinity SEEMS ok (cross your fingers) buttons click good, not really mushy, no clicking around the screen, all seems well!
The clicking could be because the glue they use stays tacky for a bit. I would assume that after a month or so it should cure and stop being tacky thus the clicking. Just an idea tho...
It's actually a shame that there are threads devoted to receiving a flawless prime. Not knocking the OP or anything, but it's crazy how we shell out 1/2 a G for a tablet and "hope" that it's a good one... I got fed up with the stutters, lock ups, questionable-hardware-so-lets-blame-it-on-the-software concerns... I had a tf201 and was lucky enough to be able to return it directly to Asus and get a full refund, then I turned around and got the tf700... Went through two of them. First one had mushy buttons and a clicky screen... It was a c7... Then got a replacement which was a c6. Turned out to be a better build than the c7, but the GPS didn't work independently like it should have. Then, I checked the c7 and that didn't work the way it should have either. Both needed google location services active for GPS to work! Between that and reading about the tf300 issues with JB and experiencing the sluggish response times, non responsive touch screen, icon-less home screens, app force closes, decreasing wifi reception and just about every problem under the sun (ala prime), I finally decided to return it to amazon for a refund. It seems like the infinity starts to get really slow as you use it more and more... It has potential, but I don't have the time or bank roll to wait and gamble...
I'm sure there are people who have perfectly working infinity's but I wasn't trying to hold my breath any longer just to hope that JB would correct all the issues... I'm actually eyeing the iPad, but will probably wait until October to see what apple has up its sleeve... I don't care for apple, but truthfully speaking... Their products have a LOT less issues and the developer devotion to some solid apps only available on the iPad have me steered in that direction. I mean, I can't get scrabble for the infinity or the prime (when i had it)... Really?!?!
Well, good luck to the infinity owners, I'll still follow the forums just to see how things turn out, but I think I'm done with Asus... It's really a shame, because they have so much potential...
Hi,
I made this video to demonstrate a rather serious Galaxy Note 10.1 Bug
that i've encountered on two devices, bought from two separate stores.
The first device was a Note 10.1 N8010 with Jelly Bean, the second (the
one on the video) is a Note 10.1 N8010 with Ice Cream Sandwitch.
Transcript:
Hi.
I have in front of me a brand new Galaxy Note 10.1.. its a WIFI-model
N8010. With brand new i mean i bought it a couple of hours ago--here is
the recepit.
I already bought a Galaxy Note 10.1, same type and model.. about 6
Months ago, but its touchscreen suffered from a very weird
touchscreen-bug that was somewhat difficult to reproduce. When I tried
to return the first model, the device went away for almost 3 months and
when I got it back the bug was still there.
Since I was using the device mainly for writing assignments and taking
notes (thats why i bought it in the first place) i gave it back and went
to another store to buy a new one, hoping that the first place will give
me my money back. I needed the device urgently and it was, like i said,
3 months and I had to make a decision.
Well, as it turns out, though, the new device, the one you can see here,
has the same bug.. and I'm going to demonstrate it now.
Right now, as you can see, the device is not in a sane state.. and the
display hasn't turned off since I started speaking. The 2, well, the 4
dots, here, here, here and here.. this one is shaking.. the 4 dots are
supposed to indicate touch activity but are rather ghost-dots caused by
mentioned bug. Here for example is another dot.. I can make several of
them.. I can use a couple of fingers.. and.. this dot is caused by my
hand, the other ones by said bug. I can't do anything right now.. I
can't press on any of these buttons.. I can't call the menu, I can't
switch the homescreen left or right.. I can't drag the.. this thing
here, whatever its name is.. touch input is pretty much impossible.
How do you cause this bug? It's pretty simple.. you roll the palm of
your hand over the display. I can demonstrate this.. I can already
demonstrate this on the lockscreen, doesn't matter.. now, there are 3
dots.. and again.. well, lets try that one again.. now we see 4 dots..
and I can't unlock the lockscreen with my finger. I can though do it
with my pen. Alright.. like i said, you roll the palm of your hand over
the display.. angle and corner don't matter.. current application in
the foreground don't matter either. When this state is active.. it's
going to be almost impossible, I already mentioned that, to use
touch-input.. and with almost I mean there are certain situations where
touch-input will partially work.. but in most cases it won't. Like
you've seen the pen works in this state.. and sometimes, but just
sometimes, it will reset said state. I'm not sure.. I'm still not able
to use touch properly.. yeah, i'm still not able but the pen still
works. Let's reproduce it one more time.
If you want to reset this state your only option is to turn off the
display.. there you go. This bug occurs on ICS and JB.. this device here
has ICS, thats 4.0.4 and my last device, the one that i wanted to give
back.. is running JB 4.1.2, i think. (...) This bug is a show stopper
for everyone who'd like to use this device for lots of writing.. and
it's also a trouble maker since the repair-guys have a hard time
reproducing it, even if you provide them with a comprehensive video.
Now, I hope this video will reach someone who has the necessary access..
because, i don't know, either I'm very, very lucky and get my hands on
two exceptional devices with the exact same bug or this affects the
whole batch or every such model.
I can show perhaps a couple of other apps if the device will let me..
which it won't right now.. Its probably time to use the pen. For
example S-note.. pen works.. touch doesn't.. it's the same story, it
doesn't depend on the application or lockscreen or mainscreen, whatever.
Let me repeat: In this state, when you see these dots, the display will
never dim or go to sleep.. so if you write something and you don't
realize that the device is in such a state.. and you go somewhere for a
couple of hours.. you will come back and you will see that the display
never turned itself off and that you lost lots of battery.
If you want to contact me, i provided my address below (...) thanks for
watching."

I don't know what kind of help anyone's going to be able to provide. It's either a s/w problem which if you've hard reset the device and it's still there indicates a h/w problem. There's been some strangeness on particular regional versions of s/w. For example, different S Note versions have had various problems and different versions are shipped in different regional ROMs. You said two Note's you've had have the same problem though which doesn't make sense if one was ICS and one JB which means they were manufactured at different times so not from the same batch. Are you using a case with magnets in it? Some people have reported strange display issues when the Note's near magnets which causes electromagnetic interference.
The Note's been out since August and sold in the millions and this is the first this type of issue's been reported. So, to your point, maybe there was a batch of bad displays that got out and all ended up in whatever region you live in. Or all versions of your region's s/w has some type of display driver bug. Mine (from August) has no touch issues either via the pen or capacitive touches and I enabled "show touch" in the developer's settings to test it. It's also a pretty obvious issue so if it were common others would have commented or posted also.
The latest 4.1.2 s/w for the N8010 is for the Nordic Countries and was released in March. From your accent I'm guessing you're in the EU. The Nordic ROM is multi-CSC so can be used on any EU N8010. You might want to try installing it via Odin to see if it changes anything.

You provided help when you tried to reproduce the problem.

It's either a s/w problem which if you've hard reset the device and it's still there indicates a h/w problem.

The first N8010 was reset a couple of times. The second wasn't but I guess that wouldn't make much of a difference.

You said two Note's you've had have the same problem though which doesn't make sense if one was ICS and one JB which means they were manufactured at different times so not from the same batch.

Both had initially ICS. The first N8010 was upgraded to JB during the 3 month repair process.

No, what you've seen in the video was just taken out of the box. There was nothing close or attached, just a tablet and two laptops on a table. The problem was initially reproducible in two different cities on several separate addresses.

Yes.. and that was pretty much the only reason why I was so convinced that my device was faulty and went out to get another one in order to get back to work as soon as possible. Now I have to deal with two retail stores.. trying to explain why I want a refund while looking like a shady guy who is trying to pull something.

When touches are shown, yes. Otherwise, hell no.. it took me months to figure out what was wrong. I blamed all possible things for the various gitches that were a direct result of this bug.. mostly the apps I was using. When the touch-input freezes started to occur on a daily basis I started to debug.. which isn't that productive when you're not root. In the end I stumbled over the "show touches" option and was lucky that such an option even exists.

Thanks for the link but right now I would just like to get my money back safely.. :|
Do you maybe know how to get in touch with samsung? Just in case the retail stores decide to give me a hard time..
I briefly experienced this issue while using my Note 10.1 in a place I don't usually use it (my brother's desk instead of my own). I was able to reproduce the issue many times by placing my palm on the screen just as in the video above.
Strangely enough, I haven't been able to reproduce the issue since that first time. I use my Note 10.1 in a number of different places (lecture halls, library, home desk, etc.), but can't seem to make it happen again.
I'm running a rooted, deodexed stock rom (4.1.2) on a NT-8013.
me too
Don't worry, you aren't crazy, I get this too.
I'm convinced its caused by pressure on the display components. My reasons are the following:
If i roll my palm across the screen relatively lightly (but still with enough pressure for the device to respond to normal touches) this never happens.
However as soon as i apply a littly more pressure I can replicate this problem every time. (To those reading thinking that I am putting an unreasonable amount of pressure on the device - I am not! I see people much more violent with their tablets day to day with no issue)
Furthermore, the more pressure I apply the longer the touches will stay after i remove my hand, suggesting that the device is kind of uncompressing.
Finally the area in which this is worst* there are some small LCD 'Mura' - that is light spots on the screen you can only see from some angles, these are normally the result of pressure.
I dont know about you guys but my note is pretty creaky, I would guess that there simply isnt enough rigidity to protect the screen components from stresses caused by pushing down on the device. (Note that i dont get this problem usually unless the device is sitting flat on its back.)
Dont get my wrong, I love my note and these issues are fortunately only an uncommon annoyance for me during typical use. But, this is kind of ****ty build quality and i will have reservations about buying another device from samsung.
*(e.g. if i roll my hand across the screen this is the most common area for a touch to 'stick')

In situations where I wasn't able to reproduce the bug (that happened every once in a while) I used a simple workaround: lock+unlock the screen and the bug was reproducible again.

You're right. After realizing that the second device has the same bug, I was close to declaring myself mental.

Mine too. It feels cheap and the only reason I bought it is because of the pen.

What's your typical use? My typical use was writing and said bug made that very inconvenient. It basically prevented me from using touch-input after writing only a couple of lines..
Maybe a short update: I returned the second device, got my money back, and sent the first device once again to $REPAIR_GUYS, this time with a link to the video above.
I'm also thinking about buying a Note 8 if I get refund for the first device.
Bottom line: The tablet was supposed to replace all the cumbersome paper I have to deliver every week and I'm out of a working device since end of january. A huge waste of money, time, time and time.

Yeah if it wasn't for the pen I bet most people would have gone for something more sturdy/better screen/stock android.
It literally is the only device which can do annotation anywhere near properly though so Its a matter of priorities.

Typical use has been taking lecture notes for several hours a day, managed a years worth of university with it, and while its not perfect
it did save my back from having to lug around lots of books and notes.
I would guess that this issue is present on all devices, just at differing scales. Hopefully you can find one where it is at a level that doesn't
bother you, though I wouldn't blame you for giving up and avoiding Samsung from now on, must be a right pain.

I would say that if you are planning on using the note 8 for lots of writing, maybe try it in store first, its probably way too small for any prolonged period, I find the 10.1 cramped and I have relatively small hands/writing. (Not helped by the fact the pen digitizer gets weird towards the edges of the screen)
Anyways, good luck!

I never really used the whole screen for writing for various reasons:
1. the pen is not precise somewhere around the middle of the screen
2. the pen is not precise at the edges (as you mentioned)
Reason 2 is something all wacom digitizers seem to share (I remember watching a guy on youtube demonstrating the "edge-effect" on the note and two other, professional wacom devices), reason 1 I can't explain.
Anyway, I always ended up just using the upper half of the screen and that's basically the main reason why I think it wouldn't make much of a difference. But on the other hand my gut tells me that you could be right.
Right now I can't shake the feeling that the note is just some random entity in Samsung's massive brute-force output. Never mind the details or the quality, after 5 different pen-tablets the fifth iteration will be just fine. Sounds a lot like Agile SW development.. just with hardware.
Same problem, demonstrated by someone else:
Have two tablets stock and no root. I have none of the described bugs and these 2 tablets are solid and very well built. Solid as any tab that I have owned. That is a strange problem and probable a batch built on Friday about quiting time.
None of those issues could have been reproduced on my Note 10.1 (GT-N8000) from Germany. Mine was bought in October 2012.
Sorry to hear that you have gotten two faulty devices :-/

I have went through 3 of these tablets, ended returning each one to best buy. I absolutely love it for drawing and sketching....until the screens bugged up. All three of mine where the gray version, I'm tempted to pick up a white and give it a try.
Btw ...the second video posted in this thread is mine. :cyclops:
Interesting thread, after reading it I decided to test mine and it's not suffering with that bug, I'm in the UK and brought it 2 months ago, it's the grey variant

Yep, all three had the same issue.
At first I thought the screen bug was from the tablet getting too hot while sketching (SketchBook). The tablet was pretty warm, not uncomfortable to touch or anything. Possibly overheating?
While streaming Netflix, the touch dots would randomly appear and not go away. The tablet wasn't warm like before when I was sketching and it wasn't even being touched.
Still tempted to try another one, i did love it when it was working and there aren't any other android devices sporting the wacom digitizer
Update:
After almost four months, some Samsung technician/representative reluctantly decided to issue a refund. Reluctantly because, and I quote, out of 100 times he tried to reproduce the bug demonstrated in not one but two videos.. he succeeded only once.
Not really satisfying but, oh well, if they dont give a f.., I won't either.
Any updates
Hi
I bought this Note for my girlfriend as a Christmas gift. She's loaded a few apps and mainly uses it to look up stuff on the web, FaceBook and things like that. The issue is the screen starts twitcihing and types random letters and will switch pges and change settings. I did a factory reset via the reset option in the settings tab. That did not help. I will post a video tonight showing the issue. Are there any other option out there??!!
Thanks

Touchscreen fixed with better USB cord on Note 10.1 2014
I have the same issue on Note 10.1 2014 SM-P605.
I've tried changing apps, dozens of keyboard settings, device covers, screen protectors, pen input, finger input, touching the corners to recalibrate, turning the divice upside down, locking, unlocking, running different tabs in chrome...way too much time on this issue.
Finally I found the cause.
A cheap monoprice USB cable attached will produce the problem 100% of the time.
Using a heafty stock USB cable works 100% of the time.
I spent three days setting up this new tablet. And it worked flawlessly, until the last day when I moved to a new room.
Now I'm loving it again.
i have problem in touch in several flashing my touch not working anymore anyone can spare me a helping hand to solve this issue sorry for my bad
