Screen sticking

Anyone else having a weird, intermittent issue with the touch screen seemingly not working right
IE: I try to scroll and instead it makes a tap where my finger lands. Unlocking the screen doesn't work 50% of the time because the lockscreen will just lag out and I have to sleep/re-wake the device
This happens on stock and after i rooted to tiamats rom

I haven't experienced or heard of this before, at least as you're explaining it.
Is this accompanied by screen dimming? Did this start after the update to HC3.2?

I use auto brightness, but I do not notice it changing during this happening
I got my XOOM with 3.2 on it

Your device may not be grounded. It's a common problem with touch screen devices. Does this happen when you're holding the device in your hands?

I really don't know, let me do some testing and see what circumstances it is replicated under.
How would grounding be determined? Its not charging...
I do have it in a silicon/rubber case. Would that be a problem?

Just for the sake of satisfying my curiosity - if you are experiencing this issue while your Xoom is docked - try placing your fingers on the back of your Xoom and typing with your thumbs.
I am trying to resolve a similar issue that I only encounter while my Xoom is docked at one place in the world - my work. Nowhere else does it do this.
I have installed a power conditioner, with no effect. It happens whenever the power is plugged into the dock. If I use an external power supply it goes away (batteries). I did switch off the florescent lighting and it is better, so it may be EM related. especially since it is a *capacitive* screen.
I have also read of people with other capacitive touch screen devices have the same issue when it is not held in their hands.
Let me know either way.
Thanks,
Frans

I have seen issue on gtab where some roms/kernel where having issue with screen calibration, there was a calibration files that could be created in the root with the name calibration.ini and upon reboot it was fixed, I do not know if this is valid for a xoom tho...
with a few rom I had NO issue whatsoever and never reused the calibration...

Well you bring an interesting point. The device was in my hands but I was not actually touching it... It had a rubber sleeve on it.
I since got the Motorola hard case which has some areas exposed and I also disabled the lock screen, and I have not been able to replicate the problem at all.
The device was docked at one point, charging, and the problem showed up aagin (recalling from memory). The fix was to power off the screen and re-wake the device. This did involve touching it, so...maybe its an electrical thing?

I had this problem with the stock 3.2 ROM. I haven't done any calibration, and don't think I need to: it works perfectly majority of the time.
I'll reenable the lockscreen and try to replicate it again.

Okay I think I'm onto the problem
I opened the case just now, still lock screen disabled, pressed just the power button and the touchscreen was acting up again.. couldn't slide to scroll, but could tap/point only
I then put my thumb on the side, as if naturally holding it without a case, and it started working normally again without any kind of power cycle.
Thoughts?

Have you dropped or jarred your Xoom a lot? Look for threads I started in this forum, I have one that explains this issue and includes a fix. My Xoom is still working flawlessly. I'd link it but pre-calculus is about to start.

I bought the XOOM second hand from someone who claimed they hardly used it. Right now sitting infront of me, the bottom right, on the back edge, there is a small pressured crease as if it was dropped (looks like the corner of my phone when i dropped it on tile).
I personally have not dropepd it, but I throw this thing onto my bed all the time, it fell out of the dock onto my hard desk once, so yeah its been knocked around.
Will doing that mod void the warranty?

I found no warranty stickers or screws when I disassembled it. The back cover is made to slide down so that Moto can do the 4G upgrade, so I doubt they want to be fooling with that type of thing anyways. I can't say for certain that sticking a piece of foam in the back of your Xoom won't void the warranty, but I can say that it fixes the issue(which also could be covered by warranty if you can get someone to believe you've got the issue, I however could not, so I had to take it upon myself).

Alright
I just ran into the problem again playing a game.. seemed like the right half of my screen just stopped working intermittently. Kept playing and it returned to normal.
I may pop it open and try the foam thing. I'm pretty good with disassembling laptops.. I can't see this being much harder.

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.

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?

Weird keyboard/digitizer problem

My friend just got a Nexus 4. When she is using the keyboard and hits the backspace quickly to erase lots of words, lines appear around the sides and bottom of the screen. The keyboard digitizer then appears to be off. If she hits the letter "b", it registers a "g", etc. Once she minimizes the keyboard and brings it back it works ok until she hits the backspace key again.
She tried installing Swiftkey but had the same result. I then installed Paranoid Android on her N4 and still have the same problem. Anyone seen this before or have any ideas? She might have to call google to get a replacement. I have had my N4 since release and never had this issue.

This IS your problem:

Hey! So i work at a phone shop and we get this problem in all the time, there is 2 things that can be causeing this problem. one being that you have a broken/damaged conecter at witch the screen its self conects to the phone. two being that the digitizer is defective or has dead touch receptor (meaning that it pick up touch in a different place than you intended it to. i would recomend contacting google and claiming it under warrenty. if that fails, you may need to take it in and get a new digitizer. Hope This Helps!! :fingers-crossed:

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).

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.

Touchscreen erratic behavior makes phone unusable

Ok, so I have a brand new Moto X Style (XT1572) bought in the UK.
After the initial 10 days when everything was working fine, the touchscreen has began showing some really irritating erratic behavior:
When I swipe, the screen interprets it as a touch
Single touch is sometimes doubled (for example, with the back navigation button)
Pulling down the notification bar gets it half way, then the phone thinks I have removed my finger so pulls it back up, even though my finger is still on the screen
The phone has never been dropped, no water splashed on it, no nasty handling, I am always extremely careful with all my devices. And the phone is not rooted or altered in any way.
So far I have tried the following, but none solved the issue:
Forced rebooted the device.
Reset to factory settings.
Re-reset factory settings and not install anything for 2 days except Twitter and Chrome.
Changed 3 different launchers besides stock.
Changed apps with alternatives.
Reset apps, reinstalled apps.
Removed screen protector and repeat previous steps.
Tried both with the fast charger connected and not connected. With factory provided cable.
Tried both with a normal charger connected and not connected. With factory provided cable.
The problem appears at random times/apps, anywhere there's scrolling involved: Chrome and Twitter are the most obvious. I have never unwillingly clicked on so many ads in the past as I have since this problem started. Worst part is that the phone decides for me if I want to touch or long touch or scroll, so it opens pages/tweets/apps I don't want to open. All at random. And then, after a while, it's fine. And then it starts again.
As you understand, the phone is unusable during the times it behaves erratically.
Not a happy first-time-Motorola customer here. Any ideas anyone?

I've made a post about weird screen issues where randomly it registers a swipe as a touch, and if you hold down on that touch, the screen goes insane and freaks out.. but the second I lift my finger up and put it down again it's fine... therefore it wsnt much of an issue for me.
Sent from my Moto X Pure Edition

I've been seeing weird stuff too. Force closing of games that play perfect on my original Moto X too...?

I think this is a result of the slim bezels. I noticed that most of the problems I have is when the skin from a finger holding the phone seems to be too close to the screen and it's registering it as a contact. Of course, this causes it not to interpret the contact you're intentionally making correctly.
My solution theory: use the included bumper or a case and see if you still have the problem. The case/bumper should help prevent unintended contact.

still have the problem with the case. it's weird Phantom touches that happen. I feel like it might be software, but idk.

Just coming back to say that the problem was not software related.
It was THE BLOODY CASE!!!
Can't believe it, can you?
It was an i-Blason Halo Series Hybrid Clear Case / Cover with TPU Bumper.
The edge of the case was registering touches on the screen!!!
Now in search of a new case.
BTW, I'd like to thank @jayochs and @AtLemacks for the great hint.
Still can't believe it...

weird. I have a regular TPU and it still does it. does it even without a case at all.

I have the same issue and a TPU case as well. I've found that locking and unlocking the device helps temporarily, but the issue soon returns. Obviously, this is not ideal... It's driving me insane.

Same issue here. Tried downgrading to 5.1.1 but the issue persists. Now I am going to try custom firmware. I Live abroad so I can not receive replacement

For all with the same issue, try operating your phone without a protection case for a few days. I found out this was the reason for the erratic behaviour.

I have been having this issue as well. It happens a lot when I am swiping text, or scrolling. When scrolling, my touch is sometimes registered as a 'click.' While swipe typing, it is as though my finger is removed then replaced, like the touchscreen input is skipping.
I will try removing the case, although this happens also when I am not holding it (phone on table). I think it might be possible that I need to push harder on the glass protector, except that the OP tried not using it altogether.

I found this thread which mentions adding some tape to the touch screen connectors.
Several people claim it solved their problem. I tried it without any success, but maybe it will help someone else.
