Screen sticking - Xoom General

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.

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?

EVO Video of touch Screen Working

We have seen multiple videos of the screen grounding issue and there are many that say theirs does not have this problem. I have two evo's and they both have this issue. I would request those who are not haveing this issue to please post a video of their phone's touch screen working while not grounded. It is not that I think anyone is lying, I just wonder if maybe the issue is not being tested correctly. I just want to see someone's that does not have this issue so I can be confident that if I return mine I have a chance of receiving one with out this problem. So please anyone that does not havethis issue show video of the phone on a pillow or bed or multiple ungrounded surfaces with the phone not plugged in to anything and demonstrate the drawing app and also the pull down notification so I can see one that works. Thanks in advance!
It's not consistent, I hadn't noticed it until after I found out...I noticed a screen tap wasn't registered when I clearly pressed.
If you look at the demo images, it shows it does work, but doesn't always work...it's not consistent like it should be.
Yes I know that it is inconsistant... that is the issue. What I am asking for is to see someone's that consistently works while not grounded. I want to see if there is even one evo out there that has a touch screen that works as it should while not grounded. I believe that possibly those that say they dont have this screen issue may not understand what we are saying or are testing it differently.
mines having the issue hold it in my hand its fine lay it on the desk it messes up
I had never noticed this until I did as you suggested and use it on my pillow and sure enough I have the same issue. Not sure if it matters or not to me yet since I only notice it during this testing and not with every day use. Guess I will have to think about it!
Just tried this out on a pillow and for me it is just the top 1/3 of the screen that goes unresponsive. Tried it with the marketplace and i could scroll just fine through the list of apps at the bottom but from the Apps, Games, Downloads Tabs up, the screen is unresponsive.

I returned my first Evo because the screen in the portrait notification bar area was dead to touch.
My new unit has no issues whether lying flat on a desk or on a bed or pillow.
Mine is going back to Sprint a new one issued, just waiting for them to get the new batch in.
I called them yesterday about it and let them know it is being returned for a new one.

Do you have a video of this?
Up until just now I thought mine was perfectly fine but I just tried setting it on a pillow and doing it and lo and behold, it's a little glitchy at the top 3rd of the screen. It's perfectly fine laying flat on a disk or stack of papers though.
This doesn't seem like such an issue to me though. Not as much as the 30fps issue. When am I ever going to be lying my phone on a pillow using it? I always hold it in my hand anyway.
If the original poster wants to keep a tally: I have the problem and have the 1st hardware revision. I also confirm grounding the screen itself did no fix the issue (since I have the invisible shield). However, the problem was immediately resolved when I grounded the battery/phone negative terminal by running a wire from it to my bare finger. Touching the screen with my other hand/finger showed the issue had disappeared.
I posted a video on YouTube, but xda won't let me post links since I am unverified.
So I am coming to the conclusion that this grounding issue effects all evo's, seeing that not one person can produce a video of it working otherwise.
My evo works fine no matter what its on. I post a video later today.

Mine works. I haven't seen an issue on any surface or lack of surface. The four other's I know who have the phone haven't had this issue either.
Mine works too, no grounding issues here. Why no video? Just don't feel the need to prove anything to you.
My EVO doesn't have this problem at all. I put it on a stryofoam plate and it was slightly less responsive, but still worked on all parts of the screen.
Mine doesn't have the screen grounding issues, but my colleague's does. I used the phones side by side and I see how the top 1/3 of his screen doesn't respond when laying flat. Mine works perfectly. Unfortunately I have bad light leakage above the buttons where his doesn't.

No video necessary. Just do what I outlay in my post:

Takes only a few minutes and you can see immediately and with real accuracy whether or not your phone is working properly.

I am asking for video simply to see if there are any phones out their that do not have this issue. If u don't want to help a fellow evo enthusiast out fine, but seeing how I have not seen a single video of the phone on an ungrounded surface which does not suffer from this issue j doubt you are testing yours the same way if it is not giving you the same result. That
Is why a video would be helpful. Because if yours indeed does not suffer from the problem then that means that there is chance that if I returned mine that I could get a working model. So if you want to help fellow forum members out... post a video.
Does anybody in here ever USE the kickstand?

Just confirmed this issue on my Omnia7.
This is retarded. Capacitive screens don't work that way.
not having any problem on my omnia 7...tried everything to try emulate some of the effects reported! not seeing any deterioration in sensitivity!
Not a pickle from my Omnia 7, Still as lush as ever and responsive as it should be, i've been mostly USING in on a pillow/soft surface when it's laying down next to me when i'm home and sitting here for hours on end.
Loving it even more when all these bugs/glitches come out and it's stomping them down.
I feel I should come back to this and apologise as I have found a pillow which messes up my phone's touch responsiveness too. Interesting.

What kind of pillow? This smells of static to me, seeing as capactive screens rely on the tiny electrical charges in your body. Polyester fabrics getsquite static, do they not?
It happens to me when I place it on my desk...
I noticed the same thing...but I didn't associate this with the soft surface, the touch screen doesn't work when it's plugged into the charger

I believe the manual is a load of BS. My iPad works fine when connected to my powerpoint. I've noticed that when the Omnia is charging via powerpoint its screen sensitivity does go down, BUT, when you hold the phone with your other hand, or even just touch part of the rear/side with one finger, the screen starts working flawlessly.... imo it could be some design flaw regarding conductivity
When I place my Omnia 7 on my car phone holder (from Capdase), the screen does not respond at times, and I can't seem to find any pattern why or how this happens. Sometimes it works, sometimes it doesn't. Once I take it off the phone holder, the screen is working fine again.
I wrote it in the other thread... but I had this problem too and after I flashed the newest firmware it was gone. Now the screen responds perfect no matter where I place the phone.
You should check the thread with omnia firmware out
Another solution I found is that you would need to Hard reset your device not through the settings but turning off and than press/hold volume down + camera and power on. Than press the middle button twice and than you will not have anymore problems with touch screen.

o really?! I thought it was just magic and the magic couldn't work when the phone was placed on soft things! im so glad someone with intelligence could teach me about this capacitive thingy whoever he is!
you have completely cleared this up for me - i now see the error of my ways. must have been having hallucinations or something. sorry for this disruption everybody!
i hope the next version of our phone uses magic because that would be really cool!
on a side note to that, after updating my firmware yesterday this dosnt seem to happen anymore. stupid hallucinations!
Had this before, after the firmware Upgrade the Problem seems to be resolved but after some time ( 1 week or so ) it's back again.
Looks like there is a fix for the laying-flat-issue for the Focus:
http://forum.xda-developers.com/showthread.php?p=11077163#post11077163
Maybe it works for some issues with the Omnia 7 as well. Did anybody already try?
Yes, have the same. If I put it on my couch, or bed. Sometimes also on hard surfaces. Doesn't bother me too much though, but it is weird.
I'm not trying to toot my own horn here...but I was literally the first person (or one of them at least) on Microsoft answers, Youtube and forums alike to raise concern about this issue.
It's a conductivity problem. As long as one hand is touching the back of the phone (sometimes near the top or sides too) then the touch screen will operate normally.
The reason it stuffs up when you have it flat is because you're not touching the back of the device, hence the conductivity flaw.
Check all this, it's a problem with the Omnia 7's, deal with it or chose another handset. I ended up keeping mine, I can live with it.

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

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?
dsf3g said:
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] Bottom half of screen not responding to touch

I had an exam and removed the battery for my phone for the duration. When I put it back in, the bottom half of my screen stopped responding to touch. The screen itself is unharmed and uncracked. The S Pen still works flawlessly. However, the bottom half of the screen ("above" about 890 pixels on the Y axis) simply does not respond to normal touch. In addition, the volume buttons no longer change my notification volume. They still work for music volume, just not touch volume. When I long-press the power button, the power menu sits at the very top of the screen and has black covering the whole bottom of the screen for some reason. When I receive calls, the buttons are right at the top. Because of this, this seems to be some sort of software issue, but I have no idea what would cause it. Has anyone with more experience with Samsung devices seen this before? Multiple restarts and battery pulls have done nothing.
EDIT: In case anyone else encounters this, it had something to do with my case. I think my phone thought it was a smart cover for some reason. I enabled and disabled smart cover and then removed and replaced the case. It's working fine now.
EDIT: Never mind, that was a coincidence. The issue is DEFINITELY that the phone thinks it has a smart cover on it, but it has nothing to do with my own case.

I've had much the same problem. While the S-Pen was able to make selections that the touchscreen wouldn't, other S-Pen functions such as Air Command and being able to start an Action Memo wouldn't work. Waiting for an extended period of time (like 24 hours) and all of a sudden it started working again. However, while I was waiting, rebooting - even performing a factory reset - didn't' fix it! I just now rebooted it and it's not working again, and it's not in a case.
Where do you find the option to enable and disable Smart Cover? On the Note 2, it was (apparently) under Security / Device Administrators, but I don't find it there. The only option I could find was in Accessories / S View Cover / Automatic Unlock but changing this setting (including rebooting between settings) hasn't solved it.

Sadly, it was just coincidence that it randomly stopped happening when I enabled and disabled the auto-unlock feature with Smart Cover. My phone started doing it again and I've been unable to repair it. I went to Verizon and they wiped my phone before telling me I'll just have to get it replaced with a refurbished one. Very frustrated. Shame there aren't any AOSP based ROMs yet (like CyanogenMod)-- they'd probably fix it since the cover thing wouldn't be a feature.
Bump.
Anyone know of the APK which would handle S View Cover behavior? If we were to disable that I imagine the problem would go away. I'm still not totally sure of the origin of the issue, but it seems to come from a combination of hardware and software problems. The hardware sensor thinks I have the case on, so the software changes things around. When I call people, I get the S View Cover style call screen. If I change the toggle in accessory settings to automatically unlock the phone when opening the cover, hitting the lock button automatically unlocks the phone as though I had no lockscreen. However, when this is disabled, the lock screen is NOT in the S View Cover form-- it looks stock. This confuses me.
Any ideas from anyone else getting the issue?
Same experience
Just to add my experience as I go. This afternoon I received an error that my SMS data could not be downloaded. Upon sliding down the notifications I was unable to control much. I ripped the majority of my hair out over this.... My pen works flawlessly everywhere though. I eventually discovered it works fine on the bottom half as you described. I have to run to some appointments, but I'll touch back after I try a few things.

Maybe it was caused by the battery insertion or backplate replacement. Perhaps too much pressure or an uneven pressure damaged the circuitry, which is now loose and causing the intermittent error.
Or perhaps it was a static discharge from the battery.
Both cases seem to me to be warrenty items.

Uh oh... I'm rooted and on Verizon. There isn't a way to unroot yet is there?

I thought the only thing necessary to unroot is to flash the stock ROM. The download is linked from the de la Vega post.

I have the same issue. I ve been trying to understand why this happened but no luck. I tried everything from updating to reseting. I first noticed it when i took the battery out as well. but the problem kinda fixed it self so i thought the phone has a spaz or something. but when i removed the battery again it happened again.
I took it to the people i bought it from and all they can say is cause there were a couple of scratches on the side of the case that it may not fall under warranty...
i was pretty angry cause its only two months old and the warranty is for a year. and the problem started happening while i was overseas so its been like that for almost a month. hopefully the sales guy is just talk cause its not up to him its just his "opinion" as he put it.
Did they explain to you why this happened? or if this is a common issue?
Hope your new phone is ok
I have this problem intermittently also. Exactly as described above.

any updates on this? im having the same problem now with my tmobile version. it fell facedown and the extended battery i had it in fell out. im going to try putting an aosp rom on it when i get home from work.
Timely post! I gave up. Verizon sending me a warranty replacement to arrive today.
Sent from my SM-N900V using Tapatalk
I have the solution!
Please. Let me know it worked for you, so people that doesn´t like to post and only read can solve this problem.
The Problem:
The half bottom screen is not working. Including the back button, the option button and the home buttom. they only work if you use the S Pen. Except for the home button. The volumes button do not work either. So the Solution is this..
take off the battery while the phone is on. YES, do not turn off the telephone and the take off the battery. Just take off the battery while the phone is on. It should work. I hope this is the solution.
One more thing. Do not allow your phone to dried up the battery completly so this wont happen again. It is better to turn it off before it dries up.!
Please let me know if it worked for you! I will let you know if this problems start again and if was only an coincidence.Hopes it not!
This tough me a good lesson! never buy a Phone from not trusted retailer, it is better to pay the full price a good store. The people that sold me the phone has a crappy warrraty like if the screen it cellphone is complete off they wont allow me to use the warranty and my phone had faulty battery conecction so it was off. then I paid 100 dollars to be repaired then this problem.
Ok, guys please let us know if it worked so people start saving their phone
Just happened to mine as well
Hard reset didn't work, on the phone with support trying to request a replacement now.
Finally Solved!
Hi
I had same problem
I did everything u said like:
mega wipe and changing rom
custom roms
taking out battery when it's on ( I Did this but I don't know It had any effects on my phone or not!)

Solution:
But I had a flip cover and I separated that from phone and thanks God,surprisingly It's Fixed and it works like a charm!!! after that I used my original cover and there is no problem till now.
Good Luck

I haven't gone back to refresh my memory but it seems to me that all these occurrances were caused by removing the back cover. Try removing it and the battery and firmly press on every spot with your thumb. First place the device face down on table padded with a single layer of a blanket. Remove the SIM and SD card and firmly reinsert. Press the back cover on and try it, then return it for warranty if it is still bad.

I also was faced with this issue today at the start of my morning BUT I FOUND A SOLUTION
I have a Sprint Galaxy Note 3 N900P Stock ROM/ no root, no mods/custom kernels/boots etc...
My device side effects were
The bottom half of my screen was not responding to my fingers,
When you press the Power Button, The options appeared on the top section of the screen instead of being the center
When I press the volume up/down keys, The volume would raise and lower, But the screen that pops up and shows you the volume had increased or decreased didnt show up
Only way to use device was with S Pen
Basically all the issues everyone listed, I had them.
Now my solution; if the issue is a hardware issue.
After dissembling my phone to see what each hardware part of the phone controls, I've come to the conclusion that there was an issue with my USB Dock Connector section of the phone. I uploaded a image pointing which connector controls it. I tried to just wipe and clean it up a bit because mines had some residue on the underneath of it. Then I plugged it back in and it started back to work %100. After I tried restarting it a few times and shaking the device up, it still works; Although I am still going to order a replacement USB Charging Port with flex cable just in case.
fixed.
This is the definitely the hardware problem.
most likely happen if u ever dropped ur phone to the ground ----------- and reboot ur phone some what later time. (can be days or months).
Temp Solution to this problem is...
face down your phone to the flat floor or a table, gently hit the back, strong enough to shock the devide, but not that strong to crack your screen.
one other simple way is to drop your phone to the floor, screen is facing down, from about 30 cm high from the floor.
"simply, hit your device like you used to fix your ur old TV. "
that is just a temp. GL.
