Lost Touching on Xoom - Xoom General

Does anyone notice that if you touch on the screen for more than around 20 seconds at the exact same spot, the touch will be suddenly lost. You have to re touch the screen to get back the response.
You can download a multi touch testing app and try and you will know what I am talking about.
The problem is also found on ATRIX......(please refer to http://forum.xda-developers.com/showthread.php?t=1000583)
I am now quite angry and wanna MOTO to have it fixed as soon as possible.

Does this manifest in any way in real-world use? I haven't noticed any touch screen problems.
There is a long list of things that people would like Motorola and/or google to fix right away: SD card, Video playback, Forced Closes to name a few.
But if a problem isn't noticed in every-day use, its not going to be much of a priority.

It'd seem more like something built in than just a bug that popped up.
At least as a developer, that's where I'd put my two cents. There's a reason for it -- although I guess I could see it being an issue if there were an app that made you hold your fingers still for 20+ sec, followed by movements on the screen... but I don't know.

It does, in fact, manifest itself in real-world use; when I hold the device with my left hand in the middle--as is usually the case--my thumb often presses against the black bar at the bottom (the one that has the time, navigation symbols, etc). After a few seconds, the screen fails to respond to touch; it does recover after a while, but until I read the op, I never realized the cause, i.e. I was removing my thumb from the bar. I was thinking of returning it, because I thought it was experiencing random freezes.

I would imagine this is a feature, whether in the hardware or implemented in the software. It's a pain in the arse from the device's perspective to be continuously polling a screen touch for 20 seconds or more.
I'm a developer too and unless it happens with _any_ continuous touch (moving or still) it's a feature not a bug.
However, if you were to touch and move for 20+ seconds then it stops responding, this is a bug, depends where and when (whether always or just in certain apps) it happens.

So, like we said before, no real-word manifestation.

I haven't been able to replicate this on my XOOM. Though, if the problem occurs on your XOOM as you describe, I can understand why that would be annoying. Maybe the problem isn't present on all devices.

I did try a multitouch testing apply. I had 8 of my fingers for more than just 20 seconds. Didn't experience a thing until I put my ninth one down. On other test app, though, it said xoom can support up to ten.

OK think I figured this out. I can replicate what you are saying. But, the whole screen doesn't lose touch sensitivity, only the menu bar. I suspect this is intentional, and part of honeycomb and not a flaw in the touchscreen hardware.
It just means that you have to remove one fingure from the menu bar before you can use it again. I can't see this causing any problem whatsoever in day to day use. Just an interesting quirk.

Don't forget , that the bar is part of the screen just like any other, if you're holding that in an app that doesn't support multitouch in such a way, it wont work.
One thing that always bugged me on my Android devices is that I can't drag the curtain (notification drop down) half way, keep hold of it and tap something inside then let go. But that's just the way it works.

Actually you are partially right. Its the honeycomb interface as a whole that becomes unresponisve, not the screen. For example if am at the home-screen and I touch the menu bar for more than 20 sec and hold my finger there, I can't open the browser.
BUT
If the browser is already open, and I hold down on the menu bar, the rest of the menu bar won't respond, but links in the browser work fine. So it's not the touchsreen that becomes unresponsive, its the Honeycomb interface.
Edit: after experimenting with different apps, it looks like my own observation isn't completely consistent. Some apps like the browser continue to respond. Others like Google books lock up. Not sure what to make of it all. But there are definitely cases where only the menu bar freezes and the app continues to respond.

Yeah, now that I know what causes this quirk to manifest, I'll just have to be careful not to rest my thumb on the bar. I must find some way to hold it firmly with my left hand; maybe some kind of suction device attached to the back.

Patient: "Doctor it hurts when I bend over."
Doctor: "Well then don't bend over!"
LOL Pretty much a universal soltion. But I agree just a quirk, doesn't seem to be a big deal, just don't hold it like that.

LOL, right!

When you play games you can easily observe this!!
For example you play car racing, you have to touch the "accelerating button" for the whole time. It will suddenly lose response and all the other cars pass me.
Another example is the mini squadron, you have to keep touching the "fire button" to fire. But after touching for 20 seconds, it losses response again.
It is so annoying when playing games. However, except this, other daily uses will not observe this problem.
AND my XOOM is the recent WIFI only version. Maybe only this version has the problem?
AND I am talking about keep touching on the same position on the screen. You dont have to use two fingers to have the problem.

I have the 4G/Wifi Xoom fully stock,
I had a similar issue yesterday, I bought one of those styluses for ipad, which do work for OG Droid and for the Xoom, had a drawing app open, set the pad down with the stylus on top, it did 2 things it start to constantly draw from tip to clip.
then I picked up the stylus, now everything seemed to be stuck to a center point every touch drew a center line to the single point for about 2 minutes, I put it down, had wouldnt respond to more pressing, then picked it up it finally returned to normal.
although I just topped putting the stylus on it while its on, and havent had the issue, but I have only played angry birds, and fruit ninja.

Wow. Not good.
One of the XOOM's biggest selling points is HD Video, and it doesn't do that well.
The other is 3D gaming. And now we're finding out the control is messed up! Seriously!
And to think I was looking forward to gaming on this thing while waiting 3 hours for my damn videos to finish encoding. What next.
I'm starting to have doubts about the XOOM again. Video and 3D gaming was supposed to be what the Tegra 2 was all about. Would like more feedback about how real this problem is, and whether games are really unplayable - is this a quirk or a serious flaw? Will have to try some gaming tomorrow. Would help if we could list games that are affected and to what degree. Maybe we can get some consensus on whether this problem is meaningful or not.
Games reported to be affected so far:
1. Car racing (which one?)
2. Mini Squadron
3. Mario Cart

My Hero does the weirdest thing...

Sometimes, I'll place the handset down on a table or whatever, and completely of it's own accord, the screen will scroll right to the second page. Then a couple seconds later, it'll scroll right again to the third, and fourth. I'll pick it up and swipe back to the home screen and put it back down, and it'll do the same thing again. Basically.... wtf?
Sometimes it does it in menus aswell, scrolling down lists one by one every few seconds when the thing isn't even in my hands.
Has anyone else experienced this? I've had a couple of replacement handsets and it's done it on all of them!

It has happened to mine, intermittently. I was hoping that it was just a little piece of grit under the trackball and that it would stop, but now you've got me worried that it is a common fault. Mine is an unlocked white in the UK, bought from Devicewire and delivered around 10 days ago...
Yup, I can comfirm it has happened to me with 3 white sim free Heros. It can happen when the device is completely undisturbed so i'm assuming it's some weird software glitch.
I can't even identify what causes it, to recreate the conditions. Seems totally random.

Hopefully a (rapid) firmware upgrade will sort it...
Could it be something on the touch screen?
I think I have seen this too! Do we all have screen protectors on? I do on my Hero....
It seems to me like the people widget caused me some issues. I have removed it and the device is faster and this bug hasn't appeared for me at all since.

Screen protector, yes. And the People widget (which I find very useful!)
Speaking about really weird things going on with the Hero. I can contribute with some funky stuff too:
When having my Hero near/under my mousecable the mousepointer (on the monitor) gets its own life. It starts moving randomly and begins to scroll the pages up and down in my browser WITHOUT me touching anything. I do have a cable connected mouse (USB). The phone has wifi, GPS and Network activated. I have not yet tested what happens with those turned off though.
Haha this is getting interesting. I noticed some mousepointer jitter when I was using the PC at work today, with my Hero nearby. I'll investigate more today.
Mine doesn't have a screen protector, but I do use the people widget on my second page. I'll remove it and see if it makes a difference to the spontaneous scrolling.
I just got my white unlocked hero 3 days ago and I just noticed this problem for the first time. The home screen would move over 1 or 2 screens without me even doing anything. Im wondering if it was major lag from previous movements I made. Im sure this is a software bug, does anyone know if HTC releases software updates for their android devices? I just switched from an iphone and hope they would release updates and fixes like apple did when something was wrong with a software release.
This phone is what... a week since launch day? We are early adopters and will find bugs. There'll be an update soon I'm pretty sure.
I think there is some interference with Wifi/Other radio and the Hero screen.
When i put mine on my desk next to my PC i cannot press all buttons on the touch screen but the wheel and hardware keys still work. When i move it 1m away from my PC this behavior is gone.
This problem happened to me when I had wet hands. All I did was wipe the hero dry and it worked fine again.

This is due to the phones aggressively high SAR value (it's really really high). I would think twice before putting this phone in your pant pockets if you ever want to have chidren

Wow, really? I already have 2 so going to keep this in my pocket from now on!!!
Aaaaaaaand HTC didn't bother fixing this in the new rom. The T9 keyboard input bug and huge lag are also unchanged.
I can confirm that this odd bug still lurks around in the official 2.73.405.5 build.
It has been suggested that it migh be due to dirt inside the trackbal housing but then why would the homescreen suddenly scroll on its own without being touched? Maybe a sensor glitch? I don't know what solution HTC are using to read the movements of the trackball though... one thing is for sure; it's not a good one....
I'm 100% sure now it's not a hardware issue. It's happened on multiple Heros I've used, not long out the box either. The only thing I've noticed that indicates any kind of pattern to the apparent randomness is that it gets a lot worse when there's a lot of mobile data transfer going on. One time I physically couldn't get it to stay on the homescreen long enough to click an icon.
Just pitching in, exact same problem here. Very strange that everyone gets it to the right :/
Just notice on mine too, some automovement in menu and home
Upgraded yesterday to new firmware (modaco)
Could be an increase of trackball sensibili? I see a settings to tweak it on blackberry device...on android?

Did google fix the sreen problem after the upgrade?

Hi, Just wonder if you still have the screen problem (register the wrong place when click) after the upgrade.
No. You should check out the humongous thread on google support forums. Googe have now abandned even giving updates on this serious problem.
http://www.google.com/support/forum...8e&hl=en&fid=04134c63c784258e00047fdfe09ae547
p.s. no fix in ere36b either (as im running that now and still experience this problem at random)
I don't understand this issue, I just don't see it on mine at all, no matter what ROM I install ... there has to be something more to this than a simple fault across all handsets ... either select faulty ones or some other factor. Mine just works 100% as expected at all times.
That said I have had no 3G issues either, no matter what radio version I use. Perhaps I am lucky ?
I think its because people are touching the edge of the screen while pressing with the other causing it to register incorrectly

That is not it, there are plenty of videos that show the touchsreen misfiring while just laying on the table. Also, the way I hold my phone I am never touching the glass surface other than with the one finger doing the touching.
With regards to some people not seeing it, this issue is very random. I can go for days without noticing it and then out of the blue it would come back, most annoying when it happens while typing something.
There is another somewhat related issue with the sensor on the n1. If you download an app called multi touch paint and try to draw two parallel lines simultaneously from say top left corner down to bottom right you will see that the lines are not straight at all and full of zigzags. Only way that this sensor recognizes multiple lines properly is if you draw perfectly vertical or horizontal lines.
There is also a discussion on developer groups where game developers are pointing out this very problem of multi toch totally being screwed up where it switches axis causing your touch to register in completely the wrong place. From the comments of the android engineer it makes it seem that the sensor hardware is just like that, cheap and low quality.

I know, I have seen all these videos and attempted to re-create many times to test I have never seen this issue once.
Don't get me wrong I can understand it being a mare of you are having it, but I just dont ever see it.
after trolling the Google thread, it seems to me there are several scenarios everyone is lumping into "screen issues" and it's going to be hard to pin it down to one source
Mine happens (touch registers on the wrong part of the screen) when I am using certain apps (Ringdroid, Browser mostly) - a couple of things clears it up ; press the sleep button, kill all tasks if you have an app for it, or change to landscape mode. For other people it's the soft keys and/or much worse. Since mine clears up with a specific action, I tend to think it is software related.
With mine it used randomly to happen but only in the Launcher (never again since 36B). I couldn't point anywhere but if I selected any app with the trackball and opend ist everything worked fine again, also the keyboard on the launcher worked well. For me it seems that it has something to do with the launcher.

Cant text right with keyboard open? Jumps around.

Recently (starting hours ago) When i try to text and use the physical keyboard it jumps around. It may scroll up the message or go over to send or things like that. I have taken my screen protector off (great, now i buy another one) and wiped it all down but it still does it.
I also reset it a few times.
Anyone else experiencing this?
I am getting the same thing. I think something is conducting on the capacitive screen as when I set the phone down or don't touch it at all, this never happens.
So should i exchange it?
I don't know. Like I said mine seems to do the same thing. I am not sure if it requires exchanging or if my fingers are brushing the side in a way they shouldn't. I'm open for suggestions myself
Hmm no mine just jumps up the text page like it scrolls the chat message up even if nothing is touching the screen.
Same thing here. Used to happen with my old myTouch but it was after a couple months of use. Uncool for it to happen on the G2 just after the 14 days have passed.
It is probably the capacitive pad thats not working right. Its probably detecting heat and scrolling on its own.
Yes get a replacement.
It's the touchpad. Move to a room with different lighting and try again.
I second the touchpad. It messes me up in the terminal by sending special characters.

I did notice it was the light now. Still does it sometimes tho.
Thanks. What do you guys mean by captive ? Heat ?
Mine does this randomly too, and I've also concluded it's the trackpad. One time I went to my home screen while it was doing it and I could watch the selection scrolling from left to right.
Haven't figured out how to fix it, usually if I lock then unlock the phone it works fine.
Mine just started doing this today. I was sitting under the A/C and i noticed whenever i would try to swype during SMS text messaging, it would highlight "Send" in orange or it would highlight and scroll up the text thread. After I moved away from the A/C, it stopped doing this. my trackpad has been fine and I have never had any issues prior to this or even after moving away from the A/C vent.
This trackpad works on heat I would guess or like others have said, possibly electrical ground current which is probably by a grid I would imagine.
Thats kinda bad for you guys. I havent had this problem at all but seems like a trackpad problem. This happen to me on my g1 onces and that was a dirty trackball

Flaky Touchscreen (Just mine?)

I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

I agree it sounds like software since the reboot fixes it but your issue doesn't seem that common. I've seen a couple now that are somewhat similar but not like the pervasive left screen glitch. I would try an exchange personally.
Sent from my ASUS Transformer Pad TF300T using Tapatalk 2
Well sorry to burst the bubble but doing a reboot to resolve the problem doesn't really rule out a hardware issue. A hardware issue can be intermittent, there's nothing that states that it must be permanent. Furthermore it might not be the rebooting that resolves it but the time that passes. In other words, the problem might occur only at 6:45PM and last for 30 seconds, if you reboot it you might not experience it again. You have no time machine so there's no way for you to really figure out when it will occur and for how long to find out what's causing it.
It's all tricky. Some errors can occur both due to software and hardware so it's hard to determine which is actually causing it for a specific issue.
But a few things lead me to believe it's hardware.
1. Why aren't more people experiencing it? A software issue results in far greater people experiencing it, especially for a group as homogenous as TF300T owners who all own the same device. The conditions are already ripe and unless a third party app is causing it, everyone is running the same code and therefore more likely to experience the problem. A hardware fault would have to be deeply ingrained into the construction, the likelihood they had let it progress that far is unlikely. Instead, it seems like a QC issue which only affects a few individuals like you.
2. Touch screen issues have been noticed in not just this device but others. It can take on the habit of registering ghost input, no input, etcetera. Happens on the Nook Color too. Happens when the device is unplugged but mostly when it is plugged in to a power source especially the wall mains. If you're not getting it from your wall mains, it's probably the device. If it is your wall mains there's nothing you can do about it.
3. There's nothing random about handling touch screen events so I find it hard to believe this is caused by software. It's more likely it's a bad touch screen feeding false events to good touch event code. The likelihood code is doing this and doing this where only you experience it and not many others (actually I've seen no other people complain about this for the TF300T and two other people complain about it for the TF101) is really low.
IMO: Just exchange it. If you make the mistake of never exchanging it you'll be stuck on that boat forever. It's probably poor QC. If the second one has the issue, that bumps up the likelihood it's a software issue as these issues in hardware are very rare and I don't think two possible units experiencing it is very common unless it was a far more common software issue. If it occurred again I would either exchange it again or get a refund.
So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.
Check the running apps it's most likely mem related
Hi,
I've had two of these for about a week now, one for my self, and one for my 10 year old. I had to go into settings and shut off all kinds of stuff that was attempting to auto updated right off the bat. These don't come with a ton of memory right out of the box.
If you press on the bottom left corner of your screen the two little squares, it will show you what is loaded in memory. Every thing that comes up on that list on the left hand side is a opened application that is actively eating up your memory.
The only way to clear these apps once opened is to power the unit off, and then back on.
On both mine and my sons, I shut off all the auto updates, there are a bunch of different settings, you really need to go through them and look too many to list but a bunch should be turned off.
I don't have any issues at this point, neither does my 10 year old, he's always playing games like Fruit Ninja and normally has three or 4 youtube windows in the back going with in 5 minutes of turning the thing on and no issues.
Mine I use more for business related stuff, and also no issues. However right out of the box the first day it was a bit flaky. They both run smooth now.
I'm just waiting on some one to give me a root app for .26 since the second I turned these both on they updated the OTA firmware which took them off .17
Anyway I hope this helps.
Good luck.

Sorry didn't see the post about issues with where you pressed the screen. That one sounds like you may need to take it back in to have serviced. I tried what you said with squeezing the screen, and pressing the back in different spots. Nope, no issues like that. I would say it requires service.

The button you refer to in the bottom left is the multi-tasking button. If you press it and swipe an app, it will be removed from that list. Android usually runs fine with lots of apps sitting in ram. The only real exception to this is apps that are poorly coded and will try to run in the background all the time.
If you want root look in the development section, there is a simple utility to let you downgrade to .17, root, voodoo backup, update, and restore.
I have same/similar problem see other thread

So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.

See here for my symptoms.
So, last night I took the tablet back to Best Buy and exchanged it (actually, had to drive to a second Best Buy because the one where I bought mine was sold out!). So far so good. Though I've only had the replacement a short time, I'm feeling good about this one. No hiccups so far. And upon running the initial setup I remembered that even during the initial setup of my first one, the screen had become unresponsive once. All in all I've got a good feeling about this one. And I do desperately want it to work because, man, I love the concept and execution of this thing.
Have you tried the creaky test with the new one to see if it's a manufacturing issue indicative of all TF300T's or whether it was just an isolated QC incident?

I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

[Q] I've noticed a problem with palm rejection.

Hey guys, I just picked up my Tegra Note and I'm enjoying it, but in testing out the potential and limitations of the DirectStylus, I came across a problem and I want to find out if it's just my problem, or if it's reproducible with all Tegra Notes with the latest system updates.
Basically, I'm using the stylus, and stylus only mode is activated. This works pretty well and ignores most/all inputs from anything except the tip of the stylus.
However, I have noticed that if I slide my finger onto the screen from the outer edge/bevel, it will often (nearly 100% of the time) register this as a touch. For an example, if I tap the home button with my finger nothing happens, however if I drag my finger from just below the screen onto the home button, it will press. Likewise I cannot scroll through home screens by normally swiping my finger, but if I swipe from off screen on the left or right, it will register. Bringing down the notification area with a finger swipe, etc, all work as well when naturally this should only be possible with the stylus.
The main problem with this is when writing/drawing with my hand resting on the edge of the device. If my palm is entirely off the screen it is fine. If my palm is entirely on the screen then stylus only works, too. However, if in the process of writing my hand slides from the side onto the screen, suddenly the stylus looses focus and I'm drawing lines with my palm.
I hope I have explained this issue correctly, and I wondered if this was a known problem? If there are any solutions? Have I messed up and set an option somewhere I shouldn't have? Should I get it replaced? Sorry for all the questions! :laugh:
Oh and it's not rooted or anything. Just stock, updated to the latest system version through the system updates.
Thanks, hope you can help!
I get a similar issue at the bottom left of the screen sometimes. It only seems to effect the bottom left but in both orientations so that rules out a hardware issue. Doing a quick lock and unlock seems to fix it for me and it functions fine until next time I turn on stylus mode. Seems hit and miss with no real way to replicate it.
It didn't seem to do it before ota 2.3 so I predict a hotfix for the issue. Its a minor issue, the battery life on 4.4.2 isn't however, 4-5hrs with lite use is pretty rubbish. I suspect that's an issue with the power saving features (I think it's stuck on Max performance all the time).
Would be nice if they fix the SD write issue but Google dictate that I think.
Mine was certainly a lot worse than that - persistent on all four edges of the screen and there is no way to stop it. 60-80% of the time it was manageable, but consistently reproducible, other times it was far worse and could only manage dots and dashes when I tried to write anything while resting my palm on the screen. It also developed a 'blind spot' problem I've noticed reported on a couple of forums - a spot where the stlus simply refused to draw - so I grew more concerned that I had a problem with the actual hardware. So, I took it into the store I bought it from, and they're going to replace it for me.
Hopefully I won't have a problem with the replacement one, because I absolutely love the tablet!
I've had similar problems... just remember, all of the stylus functionality is governed by software; the screen on this is simply a regular capacitive screen that's also capable of detecting the size and shape of what's touching it, and the rest is calculated by software. It's a neat idea, but in practice it hasn't held up as well as Nvidia would've liked us to believe. Now that I've had a Galaxy Note 2 for a couple months, I have to say that the active stylus experience blows the TN7 away, but then again it's a much more expensive technology to implement. I almost always used a pencil with my TN7 while it was my day-to-day work buddy since I found the stylus to be too sticky and hard to write with... I also found several of the issues I was having weren't as bad while using a pencil, so maybe you could give that a try. Also, remember that if the screen is dirty that it will affect the stylus's performance as the screen is so sensitive that even a little moisture could register as a touch on the screen.
I received my replacement tablet today, and it is a lot better than the one I previously had. While the problem is still there, it is far, FAR better than before. Now it seems to be a minor nuisance, rather than a consistently reproducible problem. On top of that it has a much more vibrant screen - less yellow and washed out - and no 'dead zones' when trying to write with the stylus. So while I am certain software has an impact on performance, there must have been something weird going on inside the hardware of my previous device, too.
Considering the price, the fact that others have had similar issues, and how much I like about everything else - I'm very happy with my new TN7 now!
Have same problem .... When i swipe from left or right side of the screen it detects stylus nd do all the things.... Dont knw wat to do amazon is not replacing too the tablet..!
Same problem, I don't usually mind it other when I'm using an app like sketchbook pro, it becomes really annoying.
