[Q] I've noticed a problem with palm rejection. - Nvidia Tegra Note 7

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.

Screen Accuracy Problems

The touchscreen on my titan is acting very problematically, with the screen slowly getting more and more inaccurate to touchscreen inputs, it's getting to the point where i have to use align screen 3+ times per day, and it's incredibly upsetting, is there any fix for this, or is it a hardware problem?
I'm not sure what it is but I too had that problem. After I flashed to DCD's 3.0.1 ROM,, the screen seems to be more stable. I still have to align screen every now and then. Do you you use your finger instead of the stylus? Sounds weird but I do that a lot and that might contribute to the problem.
Yeah, I do use my fingers on the screen a bit, with PointUI's Home, I don't see how that could cause it though o.o.
My I760 did that on two different phones. So i just got the xv6800, no problems yet except the ****ty video drivers-Or lack there of.
Okay, at this point the screen is going nuts, I'm probably going to have to send it off to sprint for a replacement at this point, as within 20 seconds of aligning the screen it's off by a good 5mm, and that number keeps rising.
Is you screen dirty? Along with using my fingers, my screen was dirty also. I just used a dry towel and clean the screen by blowing hot breath on it. Also, I bought new screen protectors. Yes it does seem odd that using my stylus and having a clean screen helped with my problem. Maybe my new ROM fixed the problem, I don't know. But its not as bad as it was before. Good luck.
Yeah, my problem was getting exponentially worse, off by about 6mm or so every time I'd align the screen, so I just returned it on my insurance plan.
Stylus vs Finger
If you are aligning your screen using the stylus and then using your finger for gestures and such the screen response is not aligned. You have to align with your finger in order to get a more accurate response because your finger covers so much more area than that tiny stylus tip.
I would alternate back and forth between the two, but to give an example of how severe the problem was getting, I would align the screen (with stylus) launch a program, and -already- the screen would respond about 4-5 millimeters down and 2-3 millimeters to the right of the stylus, which would make various tasks nigh-impossible.
I had the same issue and notice that it was mainly due to the fact that my screen was dirty as mentioned before. Sometimes you may even notice that your screen may not be dirty but remember that oils from our fingers and especially our ears when we talk can cause the alignment issues. Perhaps you can even change the screen protector and see if this helps. This should fix all of your issues assuming it is not an actual software problem. The one time that I did find the alignment to be a software issue, all I had to do to fix it was to callibrate the screen in both standard and panoramic view. I hope this helps...
Nah, it wasn't that, I tried cleaning off the screen with a microfiber cleaning cloth and everything, even removed the screen protector to see if that was causing it, it was a hardware defect.
Well I can say this.. I used to work for Sprint, Nextell, Verison, and ATT at various points. I know that with more of them, they usually send you out another device and you send your back. The think I love about ATT is that they will do this with a No Questions Asked policy except for the standard one involving abuse, water damage ect. After 3 defective devices, they will automatically upgrade you to another device.... Please make sure that the reasons are lagitimate so that this policy does not change but if you need to go through the hoops to get a better device that works.... Have at it. Do not take it to a store unless directed by the telephone people. Many people feel like they are techs because they own a ppc of some sort but they are not the ones that make the ultimate call. Let the corperate people make the decisions. Once you receive your device, immediately stress test it with all of the things that you will be doing with your device. Load and unload software, ect to make sure it works. If ther eis an issue, it ie better to notify them within the first 72 hours. I hope this helps again.

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.

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.

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

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?

Touchscreen problems

I have a UK Advent Vega Tetra Note 7 (the Currys /PC World version) with a slide cover. Lately the touchscreen has been exhibiting a few intermittent problems. The most annoying is that when I hit a soft key or type a letter, the screen registers multiple touches. This is extremely frustrating when I hit the back button, only to close the entire application.
The pinch and zoom sometimes plays up to. I thought that might be related to the already-identified issue over the black area to the sides of the screen being touch sensitive when they really should not be. It means that your palm often inadvertently acts as a second finger when scrolling, and zooms the screen. However the problem seems deeper, as it can happen even when being careful not to touch the bezel. And if you hold the black area off to the side of the screen, it brings up a menu.
When browsing, occasionally the touch and hold works a bit randomly, for example, when you hold a link that you want to bring up in a new tab.
I have factory reset the tablet and the problem disappears, only to reappear later. And it isn't constant either - it comes and goes.
I wonder if the issue has something to do with the magnetic slide case? Or do users without the case also experience problems? It really is a pity, as this is a great tablet otherwise.
I've had issues similar. After going back to 4.3 they seemed to go away (battery life was better too). Now back on 4.4.2 and OTA 2.3 the problems are there again. It must be a software issue, hopefully it'll be fixed along with the battery life issues.
Roll on 4.5 and let's hope nvidia give us it.
downgrade?

How did you downgrade? Is it just a case of a factory reset, then declining any upgrades?
I do hope Nvidia are aware of this problem. It really takes the shine of a good tablet.

Look here for an Advent guide to reflashing the 4.3 ROM:
http://www.adventcomputers.co.uk/product-download-select/296
You can ignore the updates afterwards. By no means though is 4.3 perfect, there is problems with the GPS and various other things that have been fixed in the latest versions.
Personally I found the latest to be best overall - Minus the battery life issues and some minor stylus/touchscreen issues.
Thank you BuToNz. I developed touchscreen problems when using the stylus after updating to 4.4.2, sensitivity was lost in an area the size of a large coin, if it registered anything in this zone it was just a messed up line. I downgraded as per the link details to 4.3 and the touchscreen with stylus is fine again.. Left feedback with Nvidia, hopefully they can repair this.

tegra note touch faulty
me 2 facing the same problem pls help..
There is a known issue that has existed since the tablet was launched where sometimes if you wake the screen by opening the cover, the touchscreen can become erratic or unresponsive. If you do a quick sleep/wake with the power button, it usually fixes it. Why Nvidia hasn't been able to fix this after a year is baffling and part of why I held off on getting a Shield Tab (among other reasons).

There is a known issue that has existed since the tablet was launched where sometimes if you wake the screen by opening the cover, the touchscreen can become erratic or unresponsive.

This has been consistent with mine and I can live with it, however recently randomly after a day or two of use, if I turn off the tab with the power button and have it charging, when I go to use it again after a random time, I get a completely unresponsive touchscreen after powering it back up with the button. No response from the screen at all. Buttons work fine, and a hard power down fixes the issue just fine, but no amount of play with either the power button or screen cover or even stylus fixes the non responsive screen. Very strange.
Still love every bit of this tab, but do hope for a Android 5.0 update soon for both it and my Shield Portable.

[Q] Are Note 7 Touch-Screen Issues Hardware or Software?

Hi guys,
I recently purchased a used Tegra Note 7 on eBay. As I'm in the UK it's the Advent Vega variety, although I don't know if that is relevant as they all appear to be the same unit; can someone confirm?
Anyway, I have noticed that every so often I lose touch response along the left or bottom edge of the screen, where the nav-bar would be in either portrait or landscape modes. This sometimes results in me having difficulty pressing the back or home button, or having difficulty selecting the settings button in the bundled camera app (this sits at the top-left of the screen). Another annoyance I found in the YouTube app; when scrolling through videos to watch, it would load the first video my finger landed on, but then continue scrolling. It's like it registers my first touch as a 'click' then realises I actually want to perform a continuous movement.
Having read a few posts scattered across the net about various touch-screen issues and some apparent software fixes, I wonder if I should stick with the tablet and wait for Lollipop to fix everything(!), or send it back on the assumption that this is an inherent fault. Because I may end up sending the tablet back, I'm hesitant to try any software fixes that require unlocking the bootloader and installing a custom recovery.
So what is the general consensus? Is the hardware flaky on these devices, or is software to blame?
I wasn't pleased when I found out that the UK models are Advent Vega (I experienced many issues with their first budget device, which was pretty horrible), but hoped all Tegra Notes were built equally regardless of the market.
Thanks in advance.
Today I was watching YouTube in reverse-landscape mode (so that the hinge on the flip case was at the top), and I couldn't click the search button at the top right of the app. It just would not register. Five minutes later, it starts working.
What's the deal with these screens?
Well, it's going back to the seller. I had no confidence in the device being able to give me hassle-free use throughout its life.
Plus there doesn't seem to be much of a community. Weird how this tablet seems to have gone under the radar.
HELLO-O-O-o-o-? ECHO-O-O-o-o-.
I get the touch screen issues occasionally too. I find that just turning the screen off and then back on usually fixes the issue.
Still it is bloody irritating!
I am miffed at the lack of community support for this device too. I thought that given the price and the fact that unlocking the bootloader is so easy that the dev community would have been all over this tablet. Shame.
Yeah it's a strange one for sure. It's still one of the most powerful tablets around, runs almost pure Android, has front-facing speakers, a half-decent stylus, easy to unlock like you say, and is an absolute bargain.
The Shield Tablet looks absolutely awesome though, hopefully that ends up with more of a following.
